Description

本発明は、会話する相手が見える範囲の距離(以下、見通し距離という。)内にいるが、声が聞こえづらかったり、聞こえなかったりして直接会話ができない距離にいる人との間で、会話する相手の姿を見ながらあたかも目の前で会話しているかのように通信をすることを可能にする赤外線通信装置に関するものである。   In the present invention, a conversation is made with a person who is within a distance (hereinafter referred to as a line-of-sight distance) in which a conversation partner can be seen, but who is in a distance where the voice is difficult to hear or cannot be directly spoken. The present invention relates to an infrared communication device that makes it possible to communicate as if talking in front of the user while watching the appearance of the other party.

人間は、視覚・聴覚という、遠距離感覚器が発達しており、対人・対物との距離を様々な方法で知覚し、その距離に応じて認知・行動の様式を変化させている。特に、知覚レベルの変化は大きく、コミュニケーションに大きな役割を果たす視聴覚に着目して対人距離を分類すると、次の3つに大別される。   Humans have developed long-distance sensations, visual and auditory senses, and perceive the distance between the person and the object in various ways, and change the cognitive and behavioral patterns according to the distance. In particular, the perceptual level changes greatly, and the interpersonal distance is classified into the following three categories by focusing on audiovisual that plays a major role in communication.

第1に、1〜2m以内の距離(以下、“接触距離”と言う)では、手の届く範囲で、お互いの顔をつきあわせてコミュニケーションが行われ、相手の姿・声ともにはっきりと知覚可能であり、非常に高い臨場感がある。   First, at distances within 1 to 2 meters (hereinafter referred to as “contact distance”), communication is performed with each other's faces within the reach of the hands, and the other person's figure and voice can be clearly perceived. It has a very high presence.

第2に、5mから十数m程度の距離(“見通し距離”)では、相手の姿は見えるが、声がはっきりと聞こえない。大声をあげる、ジェスチャーを交える等によって意思を伝えることはできるが、コミュニケーションの精度、臨場感は大きく落ちてしまう。   Second, at a distance of about 5m to a few dozen meters ("line-of-sight distance"), the opponent can be seen but the voice cannot be heard clearly. Although you can communicate your intentions by making loud voices or exchanging gestures, the accuracy and presence of the communication will be greatly reduced.

第3に、数十m以上の距離(以下、“遠隔距離”と言う)では、お互いの姿・声ともに知覚することができず、何らかの道具を介することなくコミュニケーションを成立させることはできない。   Third, at a distance of several tens of meters (hereinafter referred to as “remote distance”), it is impossible to perceive each other's figure and voice, and communication cannot be established without using any tools.

この距離の分類の中で、接触距離でのコミュニケーションは別として、他の距離でのコミュニケーションは何らかの補助手段が必要とされる。遠隔距離でのコミュニケーションについては、携帯電話、テレビ電話、無線機をはじめ、これまでも各種の通信装置が提案されているが、見通し距離においては、コミュニケーションに使用可能な通信装置は数少ない。   In this distance classification, apart from communication at contact distance, communication at other distances requires some auxiliary means. For communication at a remote distance, various communication devices have been proposed so far, including cellular phones, videophones, and wireless devices, but there are only a few communication devices that can be used for communication at a line-of-sight distance.

発明者らは、見通し距離にいる相手との会話に対する一手段として、既に “Visualresonator:interfaceforinteractivecock−tailpartyphenomenon”の題名で「Ext.Abstracts CHI2006」の1505−1510頁に発表した論文(非特許文献1)のFig.2及びその説明文で、使用者の頭部に装着するヘッドフォン型のアダプタに、赤外線送信部、赤外線信号受信部及びマイクロフォンを装備し、このアダプタを装着した複数人が互いに相手を確認している状態で、赤外線を利用して通信するシステムを提示している。   The inventors have already published a paper published on pages 1505-1510 of “Ext. Abstracts CHI2006” under the title of “Visualresonator: interfacinginteractivecock-tailpartyphenomenon” (Non-Patent Document 1) as a means of conversation with a partner at a line-of-sight distance. FIG. 2 and its explanation, the headphone adapter to be worn on the user's head is equipped with an infrared transmitter, an infrared signal receiver, and a microphone, and a plurality of people wearing this adapter confirm each other. In the state, the system which communicates using infrared rays is presented.

さらに、特開2009−88803「赤外線通信装置」では、全方向性赤外線受信機を用いて呼び出し伝達部を設けること、呼び出し方向を検出すること等を開示している。   Furthermore, Japanese Unexamined Patent Application Publication No. 2009-88803 “Infrared Communication Device” discloses providing a call transmission unit using an omnidirectional infrared receiver, detecting the calling direction, and the like.

Inami, “Visualresonator: interfacefor- teractiveactive-tailpartyphenomenon”, Ext. Abstracts CHI 2006, pages 1505-1510

従来提案されているシステムでは、赤外線通信を行う者同士が相手を確認(認識)している状態で赤外線信号の送受信を行い、通信手段により会話を行うことができる。また、見通し距離内にいるが、相手が自分を認識していない場合でも、全方向性赤外線信号受信部と呼び出し伝達部とを備えて、相手に通信を望む者がいることを認識させて会話を開始することができる。全方向からの信号を受信する無指向性赤外線信号受信部は、使用者を中心にして全方向から送信されてくる赤外線信号を受信する。そして呼び出し伝達部は、無指向性赤外線信号受信部が赤外線信号を受信すると、使用者に呼び出しがあることを振動、音響及び発光の少なくとも一つによって伝達する。   In a system proposed in the past, infrared signals can be transmitted and received in a state where the parties performing infrared communication confirm (recognize) each other, and conversation can be performed by communication means. In addition, even if you are within the line-of-sight distance, but the other party does not recognize you, you can have an omnidirectional infrared signal receiver and a call transmission unit to make sure that the other party wants to communicate. Can start. An omnidirectional infrared signal receiver that receives signals from all directions receives infrared signals transmitted from all directions with the user at the center. Then, when the omnidirectional infrared signal receiving unit receives the infrared signal, the call transmission unit transmits that the user has a call by at least one of vibration, sound, and light emission.

既に発明者が提案した特許文献1の特開2009−88803「赤外線通信装置」や、非特許文献1のJ.Watanabe,H.Nii,Y.Hashimoto、M.Inami、「Visualresonator:interfaceforinteractivecock−tailpartyphenomenon」、Ext.Abstracts CHI2006、1505−1510頁においては、お互いの会話中に常に相手の方向を向き続けなければならないというデメリットがある。また、呼出方向が直感的に分かるにはさらに改善の余地を残していた。   Japanese Patent Laid-Open No. 2009-88803 “Infrared communication device” disclosed in Japanese Patent Application Laid-Open No. 2009-88803 already proposed by the inventor and J. Pat. Watanabe, H.M. Nii, Y .; Hashimoto, M.H. Inami, “Visualresonator: interfacefor- teractiveactive-tailpartyphenomenon”, Ext. In Abstracts CHI 2006, pages 1505-1510, there is a demerit that it is necessary to always face the other party during the conversation. In addition, there remains room for improvement in order to intuitively understand the calling direction.

これらの装置は、見通し距離にいる相手との会話は可能となっているが、従来提案した装置からさらにマン・マシンインターフェイスを向上させて、人間の自然な動作の中で適切に補助手段としての機能を果たす装置が望まれる。例えば、相手が見通し距離にいるとき、まず声を掛けて、会話の意志を伝えるであろう。会話の相手は、遠くから自分を呼びかける声が聞こえたときは、まず、相手を探すために周囲をキョロキョロと見渡して、呼びかけている人を探すであろう。声が聞こえた方向を直感的に感じてその方向を向くが、音声は空気中を伝わる振動波であり、壁等による反射の影響もあって、意外と音源の方向を感知するのは難しいものである。このため、頭を回転させる動作により目で周囲を見渡して相手を捜すことになる。そして、自分を向いて何らかの合図を送っている人を見つけると、ジェスチャー交じりでの会話が開始されるであろう。   These devices can talk with the other party at the line-of-sight distance, but the man-machine interface has been further improved from the previously proposed devices to appropriately serve as auxiliary means in the natural human movement. A device that performs the function is desired. For example, when the opponent is at a line-of-sight distance, he will first speak and communicate the will of the conversation. When the conversation partner hears a call to him from a distance, he or she will first look around and look for the person who calls. Intuitively feel the direction in which the voice was heard and turn to it, but the sound is a vibration wave that travels in the air, and it is difficult to detect the direction of the sound source unexpectedly due to the influence of reflections from the walls etc. is there. For this reason, the movement of rotating the head looks around with the eyes to search for the opponent. And if you find someone who is pointing to you, you will start a conversation with gestures.

本発明は、この様な場合での会話手段、即ち音声を入出力するための補助手段を提供するものであり、人間の自然な動作の中で装置を動作させることを目的としている。
The present invention provides a conversation means in such a case, that is, an auxiliary means for inputting / outputting a voice, and an object of the present invention is to operate the apparatus in a natural human movement.

本発明は、見通し距離にいる相手との会話手段を提供するものであり、特定方向からの赤外線信号を受信する複数の呼出用指向性赤外線信号受信部と、前記呼出用指向性赤外線信号受信部で受信された呼出信号を、振動、音または光の情報に変換する信号変換部と、前記信号変換部で変換した信号を振動、音または光として受信者に通知する呼出部と、特定方向からの赤外線信号を受信する会話用指向性赤外線信号受信部と、受信信号を変換して音声信号にする出力音声変換部と、音声信号を可聴域の音声として出力する音声出力部と、音声を入力する音声入力部と、音声入力部から入力した前記音声を赤外線信号に変換する入力音声変換部と、特定方向への赤外線信号を送信する会話用指向性赤外線信号送信部と、装置全体の信号を制御する制御部と、からなり、少なくとも前記会話用指向性赤外線信号受信部と前記会話用指向性赤外線信号送信部とは、顔の正面方向に送受信信号の指向性を一致させ、前記音声出力部と前記音声入力部を一体として頭部に配置し、複数の前記呼出用指向性赤外線信号受信部では、指向性方向を異なる方向として、それぞれの方向の信号を受信させ、呼出信号を受信した前記呼出用指向性赤外線信号受信部に対応する前記呼出部から振動、音または光により呼出が行われることを特徴とする対話型赤外線通信装置により実現される。   The present invention provides a means for conversation with a partner at a line-of-sight distance, and includes a plurality of directional infrared signal receiving units for receiving infrared signals from a specific direction, and the directional infrared signal receiving unit for calling. A signal conversion unit that converts the call signal received in the above into vibration, sound, or light information, a call unit that notifies the receiver of the signal converted by the signal conversion unit as vibration, sound, or light, and a specific direction. A directional infrared signal receiver for conversation that receives the infrared signal, an output voice converter that converts the received signal into a voice signal, a voice output unit that outputs the voice signal as an audible voice, and a voice input A voice input unit, an input voice conversion unit that converts the voice input from the voice input unit into an infrared signal, a directional infrared signal transmission unit for conversation that transmits an infrared signal in a specific direction, and a signal of the entire apparatus Control And at least the directional infrared signal receiving unit for conversation and the directional infrared signal transmitting unit for conversation match the directivity of the transmitted / received signal in the front direction of the face, and the voice output unit and the The voice input unit is integrally arranged on the head, and the plurality of directional infrared signal receiving units for calling receive signals of each direction with different directivity directions and receive the calling signal. The interactive infrared communication apparatus is characterized in that a call is made by vibration, sound or light from the calling unit corresponding to the directional infrared signal receiving unit.

会話したい相手が見通し距離にいる場合には、相手に向かって音声入力部を介して声を掛ける。そして、会話用指向性赤外線信号送信部から赤外線信号を相手の方向へ送信する。信号の受信部は複数の呼出用指向性赤外線信号受信部からなり、全方向をカバーするように配置されている。呼出側の会話用指向性赤外線信号送信部により送信された赤外線信号を、相手側は、いずれかの呼出用指向性赤外線信号受信部で受信すると、その呼出用指向性赤外線信号受信部に対応した呼出信号の信号変換部で呼出部の動作を行う信号に変換され、呼出部の動作により呼出相手に通知される。呼出部により相手に直感的に分かる方法として、振動、音または光により提示し、相手側はどの方向から送信された信号かを感知する。そして、受信側が感知した方向に顔を向けると、送信側の会話用指向性赤外線信号送信部と受信側の会話用指向性赤外線信号受信部の指向性が一致し、受信側の会話用指向性赤外線信号受信部が赤外線信号を受信し、出力音声変換部において音声信号に変換して、音声出力部から可聴域の音声として出力する。この時、会話用指向性赤外線信号送信部も、会話を求めて声を掛けた呼出人側に向いている。このため、音声入力部より音声を入力し、入力音声変換部により電気信号に変換し、会話用指向性赤外線信号送信部より赤外線信号として送信する。   When the other party who wants to talk is at a line-of-sight distance, he speaks to the other party via the voice input unit. And an infrared signal is transmitted to the direction of the other party from the directional infrared signal transmission unit for conversation. The signal receiving unit includes a plurality of directional infrared signal receiving units for calling and is arranged so as to cover all directions. When the other party receives an infrared signal transmitted by the calling directional infrared signal transmission unit at one of the calling directional infrared signal reception units, the corresponding directional infrared signal reception unit corresponds to the calling directional infrared signal reception unit. The call signal is converted into a signal for performing the operation of the calling unit by the signal conversion unit, and notified to the calling party by the operation of the calling unit. As a method that can be intuitively understood by the caller by the calling unit, it is presented by vibration, sound, or light, and the other party senses from which direction the signal is transmitted. When the receiving side turns its face in the direction sensed, the directivity of the transmitting directional infrared signal transmitter on the transmitting side matches the directivity of the receiving directional infrared signal receiver on the receiving side. The infrared signal receiving unit receives the infrared signal, converts the infrared signal into an audio signal in the output audio conversion unit, and outputs the audio signal from the audio output unit as audio in the audible range. At this time, the directional infrared signal transmission unit for conversation is also directed to the calling party who calls out for conversation. For this reason, voice is input from the voice input unit, converted into an electrical signal by the input voice conversion unit, and transmitted as an infrared signal from the directional infrared signal transmission unit for conversation.

呼出部は、人間が感知できる振動、音や光により実現され、赤外線信号の送信方向に指向性を有するいずれかの呼出用指向性信号受信部が受信して、対応する呼出部が動作するから、どの方向から声を掛けられたかが容易に感知できる。   The calling unit is realized by vibration, sound, or light that can be detected by humans, and any of the calling directivity signal receiving units having directivity in the transmission direction of the infrared signal is received and the corresponding calling unit operates. It is easy to detect from which direction the voice is spoken.

さらに、全方向からの赤外線信号を受信する会話用無指向性赤外線信号受信部を備え、会話用指向性赤外線信号受信部と会話用無指向性赤外線信号受信部を切り替え可能とすることにより、複数の人との会話をしたい場合にも適用できる。この場合に、会話用指向性赤外線信号受信部と会話用無指向性赤外線信号受信部を切り替え可能とすることにより、複数の人からの音声を聴いたり、特定の人からの音声を聴いたりすることができるため応用範囲が広がり、場面に応じた柔軟な使用方法が可能となる。   Furthermore, a conversational omnidirectional infrared signal receiving unit that receives infrared signals from all directions is provided, and a plurality of conversational directional infrared signal receiving units and a conversational omnidirectional infrared signal receiving unit can be switched. It is also applicable when you want to have a conversation with other people. In this case, by enabling switching between the conversational directional infrared signal receiving unit and the conversational omnidirectional infrared signal receiving unit, it is possible to listen to voices from a plurality of people or to listen to voices from a specific person. Therefore, the application range is widened, and a flexible usage method according to the scene becomes possible.

さらに全方向に赤外線信号を送信する会話用無指向性赤外線信号送信部を備え、会話用指向性赤外線信号送信部と会話用無指向性赤外線信号送信部を切り替え可能とすれば、複数の人に音声を送信することも可能である。   Furthermore, a conversational omnidirectional infrared signal transmission unit that transmits infrared signals in all directions is provided, and if the conversational directional infrared signal transmission unit and the conversational omnidirectional infrared signal transmission unit can be switched, a plurality of people can be switched. It is also possible to transmit audio.

また、全方向からの赤外線信号を受信する会話用無指向性赤外線信号受信部と全方向に赤外線信号を送信する会話用無指向性赤外線信号送信部をさらに備え、会話用指向性赤外線信号受信部と会話用無指向性赤外線信号受信部が切り替え可能であり、会話用指向性赤外線信号送信部と会話用無指向性赤外線信号送信部が切り替え可能とすることで、複数の人からの音声を聴いたり、複数の人に音声を発したり任意の方法で会話が可能となり、一層応用範囲が広がり、場面に応じてさらに柔軟な使用方法が可能となる。   In addition, a conversational omnidirectional infrared signal receiving unit for receiving infrared signals from all directions and a conversational omnidirectional infrared signal transmitting unit for transmitting infrared signals in all directions are further provided. The conversational omnidirectional infrared signal receiver can be switched, and the conversational directional infrared signal transmitter and the conversational omnidirectional infrared signal transmitter can be switched to listen to audio from multiple people. It is possible to utter a voice to a plurality of people or to have a conversation by an arbitrary method, further expanding the application range, and enabling a more flexible usage method according to the scene.

会話用指向性赤外線信号受信部と会話用指向性赤外線信号送信部を頭部から取り外し可能として、体の正面に配置可能な取付部を備え、会話用指向性赤外線信号受信部と会話用指向性赤外線信号送信部を取付部に移動させたときは、体の正面方向への指向性を有するようにすることができる。これにより、会話中に相手を見続ける必要が無く、体の正面がお互いに向き合っていれば会話が可能である。   The directional infrared signal receiver for conversation and the directional infrared signal transmitter for conversation can be removed from the head and equipped with a mounting part that can be placed on the front of the body. When the infrared signal transmission part is moved to the attachment part, it is possible to have directivity in the front direction of the body. Thereby, it is not necessary to continue to look at the other party during the conversation, and the conversation is possible if the fronts of the bodies face each other.

状況によっては会話相手と向き合うことができない場合もあるが、このような場合には、会話用指向性赤外線信号受信部と会話用指向性赤外線信号送信部を会話の相手に向けることができるようにしておくことが可能となるようにしてもよい。状況により柔軟に対処できる様に、会話用指向性赤外線信号受信部のみ、或いは会話用指向性赤外線信号送信部のみを分離してもよい。   Depending on the situation, it may not be possible to face the conversation partner. In such a case, the conversational directional infrared signal receiver and the conversational directional infrared signal transmitter should be directed to the conversation partner. It may be possible to keep it. Only the directional infrared signal receiver for conversation or only the directional infrared signal transmitter for conversation may be separated so that it can be flexibly dealt with depending on the situation.

また、会話用指向性赤外線信号受信部と会話用指向性赤外線信号送信部の信号検知部を設け、
複数の呼出用指向性赤外線信号受信部のいずれかで信号を受信した場合は、会話用指向性赤外線信号受信部、出力音声変換部、音声出力部、会話用指向性赤外線信号送信部、入力音声変換部、音声入力部と信号検知部を駆動し、信号検知部が何れの送受信部からも予め定められた入出力信号が無いことを検知した場合は、会話用指向性赤外線信号受信部、出力音声変換部、音声出力部、会話用指向性赤外線信号送信部、入力音声変換部、音声入力部と信号検知部の駆動とを停止させる。
In addition, a signal detector for the conversational directional infrared signal receiver and the conversational directional infrared signal transmitter is provided.
When a signal is received by any one of a plurality of directional infrared signal reception units for calling, a directional infrared signal reception unit for conversation, an output voice conversion unit, a voice output unit, a directional infrared signal transmission unit for conversation, an input voice When the conversion unit, the voice input unit and the signal detection unit are driven, and the signal detection unit detects that there is no predetermined input / output signal from any of the transmission / reception units, the directional infrared signal reception unit for conversation, the output The driving of the voice conversion unit, the voice output unit, the conversational directional infrared signal transmission unit, the input voice conversion unit, the voice input unit, and the signal detection unit is stopped.

対話型赤外線通信装置では、まず複数の呼出用指向性赤外線信号受信部、信号変換部、呼出部及び制御部の電源をオンにしておき、呼出信号を受信可能な状態としておく。いずれかの呼出用指向性赤外線信号受信部で呼出信号を受けたら、会話用指向性赤外線信号受信部、出力音声変換部、音声出力部、会話用指向性赤外線信号送信部、入力音声変換部、音声入力部と信号検知部の電源をオンにして駆動状態とする。信号検知部は、入出力信号によりお互いの会話が続いていることを検知し、会話の終了は、予め定められた時間内に信号を検知しなかったときは会話が終了したとして、会話用指向性赤外線信号受信部、出力音声変換部、音声出力部、会話用指向性赤外線信号送信部、入力音声変換部、音声入力部と信号検知部の電源をオフにして駆動を停止させる。これらの動作は制御部にて行われ、電力消費を抑えることができる。   In the interactive infrared communication apparatus, first, the plurality of calling directivity infrared signal receiving units, the signal converting unit, the calling unit, and the control unit are turned on so that the calling signal can be received. Upon receiving a call signal at any of the directional infrared signal receiving units for calling, a directional infrared signal receiving unit for conversation, an output voice conversion unit, a voice output unit, a directional infrared signal transmission unit for conversation, an input voice conversion unit, The sound input unit and the signal detection unit are turned on to be in a driving state. The signal detection unit detects that the conversation is continuing with the input / output signal. The end of the conversation is determined to be the conversation end when the signal is not detected within a predetermined time. The directional infrared signal receiving unit, the output voice conversion unit, the voice output unit, the conversational directional infrared signal transmission unit, the input voice conversion unit, the voice input unit, and the signal detection unit are turned off to stop driving. These operations are performed by the control unit, and power consumption can be suppressed.

また、信号検知部が動作している間は、全ての呼出用指向性赤外線信号受信部、全ての信号変換部、全ての呼出部の駆動を停止させることにより、消費電力の低減が可能となる。   In addition, while the signal detection unit is operating, it is possible to reduce power consumption by stopping the driving of all the directional infrared signal receiving units for calling, all the signal converting units, and all the calling units. .

音声出力部は骨伝道によるイヤフォン、音声入力部は骨伝導によるマイクとすることにより、周囲の雑音の影響を抑止することができる。特に人ごみの中や、工事中の現場で効果的である。   By using an earphone based on bone evangelism as the audio output unit and a microphone based on bone conduction as the audio input unit, the influence of ambient noise can be suppressed. This is especially effective in crowds and construction sites.

対話型赤外線通信装置では、特定方向からの赤外線の呼出信号を受信する複数の呼出用指向性赤外線信号受信部と呼出部を、他と分離して一体として呼出装置を構成し、呼出信号を受信した受信部に対応する呼出部で光により受信者に通知するようにしてもよい。   In an interactive infrared communication device, a plurality of directional infrared signal receivers for calling that receive infrared calling signals from a specific direction and a calling unit are separated from others to form a calling device and receive a calling signal. The caller corresponding to the received receiver may be notified to the receiver by light.

呼出装置を別に構成することで、本体の軽量化が可能となるばかりでなく、周囲に置いた方が便利な場合にも対応できる。この場合は、頭部に設置されていないため呼出通知は、少なくとも光による可視化された信号を用いる。赤外線信号の受信者は、光信号により通知された方向を向いて送信者と向き合う。   By configuring the calling device separately, not only the weight of the main body can be reduced, but also the case where it is more convenient to place it around can be accommodated. In this case, since it is not installed on the head, the call notification uses at least a signal visualized by light. The receiver of the infrared signal faces the transmitter in the direction notified by the optical signal.

さらに呼出装置に、音声入力部、会話用指向性赤外線信号受信部と会話用指向性赤外線信号送信部を一体として送受信装置を構成し、複数の呼出用指向性赤外線信号受信部の指向性を示す面方向と直交する方向に、会話用指向性赤外線信号受信部と会話用指向性赤外線信号送信部とを配置し、音声入力部に口から音声を入力する操作をする場合に、会話用指向性赤外線信号受信部と会話用指向性赤外線信号送信部とが顔の正面方向に指向性を有する構造とする。   Further, the call device is configured by integrating a voice input unit, a conversational directional infrared signal reception unit, and a conversational directional infrared signal transmission unit to form a transmission / reception device, and shows the directivity of a plurality of call directional infrared signal reception units. When a conversational directional infrared signal receiving unit and a conversational directional infrared signal transmitting unit are arranged in a direction orthogonal to the surface direction, and speech is input to the voice input unit, speech directivity is used. The infrared signal receiving unit and the directional infrared signal transmitting unit for conversation are structured to have directivity in the front direction of the face.

この送受信装置に、音声入力部、会話用指向性赤外線信号受信部と会話用指向性赤外線信号送信部を設けることにより、呼出部から光で通知されると、送受信装置を口元に持ってきて音声入力部から音声を入力する。この動作を行うことにより、会話用指向性赤外線信号受信部と会話用指向性赤外線信号送信部は、会話の相手側方向を向くことになり、お互いの音声の送受信が可能となり、会話することができる。そして、複数の呼出用指向性赤外線信号受信部は、会話用指向性赤外線信号受信部及び会話用指向性赤外線信号送信部と直交する方向に配置されているから、会話中は、垂直方向を向いていることになり、他の相手からの呼出信号を受信することはない。従って、会話中は排他的にお互いの会話に集中できる。   By providing a voice input unit, a conversational directional infrared signal reception unit, and a conversational directional infrared signal transmission unit in the transmission / reception device, when the call unit notifies the user of the light, the transmission / reception device is brought to the mouth and the voice is transmitted. Input voice from the input section. By performing this operation, the directional infrared signal receiving unit for conversation and the directional infrared signal transmitting unit for conversation are directed toward the other side of the conversation, so that they can transmit and receive each other's voice and can talk. it can. The plurality of directional infrared signal receiving units for calling are arranged in a direction orthogonal to the directional infrared signal receiving unit for conversation and the directional infrared signal transmitting unit for conversation. Therefore, the call signal from the other party is not received. Therefore, it is possible to concentrate on each other's conversation exclusively during the conversation.

以下図面を参照して本発明の対話型赤外線通信装置の実施の形態を詳細に説明する。   Embodiments of the interactive infrared communication apparatus of the present invention will be described below in detail with reference to the drawings.

図1は、本発明の基本的な概念を説明する図であり、お互いが道路を隔てて歩いている状況を示している。   FIG. 1 is a diagram for explaining the basic concept of the present invention, and shows a situation where each other is walking across a road.

本発明による対話型赤外線通信装置10の装着者A及びBは、お互い直接声が届かない距離にいても、自分がコミュニケーションをとりたい相手の方向を向き、話し掛けることで相手に呼びかけることができる。装着者Aが装着者Bとコミュニケーションをとる場合は、図1(A)に示したように、装着者Aが装着者Bに向かって声を掛ける。すると、装着者Bは呼出部からの通知に気付き、発信側の装着者Aを捜す。そして、図1(B)に示したようにお互いが相手の存在に気付き、向かい合うことで会話を開始する。向かい合ったときに相手のマイクロフォンからの声が明瞭に聴こえるようになっているため、見通し距離においても会話する相手を見ながら、近接距離にいて会話をするかのように会話をすることができる。   The wearers A and B of the interactive infrared communication apparatus 10 according to the present invention can call the other party by speaking and pointing in the direction of the other party that he / she wants to communicate with, even if the wearers A and B are at a distance where the voices do not reach each other directly. When the wearer A communicates with the wearer B, the wearer A calls out to the wearer B as shown in FIG. Then, the wearer B notices the notification from the calling unit and searches for the wearer A on the transmission side. Then, as shown in FIG. 1 (B), each other notices the existence of the other party and starts a conversation by facing each other. Since the voice from the other party's microphone can be clearly heard when facing each other, it is possible to talk as if talking at a close distance while looking at the other party who is talking even at a line-of-sight distance.

図2は、本発明による対話型赤外線通信装置10のブロック図であり、具体的な実施例に共通する機能を説明する。   FIG. 2 is a block diagram of the interactive infrared communication device 10 according to the present invention, and describes functions common to specific embodiments.

呼出用指向性赤外線信号受信部12は、4個の呼出用指向性赤外線信号受信部12−1〜12−4からなり、前後左右方向からの呼出信号を受信する。この呼出用指向性赤外線信号受信部は、4個に限らず、任意の数でよい。また、複数の呼出用指向性赤外線信号受信部で全方向をカバーするような指向性特性を備えるようにしているため、4個の呼出用指向性赤外線信号受信部12−1〜12−4を有する場合はそれぞれが約90度の角度をカバーする。次に信号変換部14において、各指向性赤外線呼出信号受信部12−1〜12−4に対応して赤外線信号を電気的に変換して呼出を行うための信号に変換する信号変換部14−1〜14−4と呼出部16−1〜16−4があり、呼出部16にもそれぞれ対応した呼出部16−1〜16―4がある。呼出部は、呼び出された相手側が、現在立つ位置のどの方向から呼び出されているかが分かるように、赤外線信号の発信方向からの信号を受信した呼出用指向性赤外線信号受信機12−1〜12−4のいずれかに対応した呼出部16−1〜16−4により、信号が伝えられる。呼出方法としては、振動、音、光等があるが、人間が知覚できる方法であればその他の方法であってもよい。   The calling directional infrared signal receiving unit 12 includes four calling directional infrared signal receiving units 12-1 to 12-4, and receives call signals from the front, rear, left, and right directions. The number of the directional infrared signal receiving units for calling is not limited to four, but may be any number. In addition, since the directional infrared signal receiving units 12-1 to 12-4 are provided with directivity characteristics that cover all directions with a plurality of directional infrared signal receiving units for calling. Each covers an angle of about 90 degrees. Next, in the signal conversion unit 14, the signal conversion unit 14-converts the infrared signal into a signal for calling by electrically converting the infrared signal corresponding to each of the directional infrared call signal reception units 12-1 to 12-4. 1 to 14-4 and calling units 16-1 to 16-4, and the calling unit 16 also has corresponding calling units 16-1 to 16-4. The calling unit receives the signal from the direction in which the infrared signal is transmitted so that the called party can be called from which direction of the currently standing position. A signal is transmitted by the calling units 16-1 to 16-4 corresponding to any of the -4. The calling method includes vibration, sound, light, and the like, but other methods may be used as long as they can be perceived by humans.

呼出を受けた相手側(以下受信側という。)は、呼出部16での呼出方向を知覚して、その方向を向いて赤外線信号を送信した側(以下送信側という。)を捜し、見つけた場合はその方向を向く。そうすると、受信側の会話用指向性赤外線信号受信部20と送信側の会話用指向性赤外線信号送信部28の指向性が一致するから、お互いの会話が可能となる。会話用指向性赤外線信号受信部20には出力音声変換部22があり、受信信号を音声信号に変換し、音声出力部24から音声を出力する。また、会話用指向性赤外線信号送信部28には、入力音声変換部30があり、音声入力部32から入力された音声信号を入力音声変換部30により赤外線信号に変換し、送信する。これにより、お互いが排他的に会話できることとなる。会話用指向性赤外線信号受信部20と会話用指向性赤外線信号送信部28の指向特性は、お互いが向き合って会話をするため、例えば10度〜30度程度の角度をカバーすればよい。カバーする角度は、用途によって任意に設計可能である。   The other party receiving the call (hereinafter referred to as the receiving side) perceives the calling direction at the calling unit 16 and searches for and finds the side (hereinafter referred to as the transmitting side) that has transmitted the infrared signal in that direction. If so, turn in that direction. Then, since the directivity of the conversational directivity infrared signal receiving unit 20 on the reception side and the directivity infrared signal transmission unit 28 on the transmission side coincide with each other, it is possible to have a conversation with each other. The conversational directional infrared signal receiving unit 20 includes an output voice conversion unit 22 that converts the received signal into a voice signal and outputs the voice from the voice output unit 24. In addition, the conversational directional infrared signal transmission unit 28 includes an input voice conversion unit 30. The voice signal input from the voice input unit 32 is converted into an infrared signal by the input voice conversion unit 30 and transmitted. As a result, each other can have an exclusive conversation. The directivity characteristics of the conversational directional infrared signal receiving unit 20 and the conversational directional infrared signal transmission unit 28 may cover an angle of, for example, about 10 degrees to 30 degrees in order to talk with each other. The covering angle can be arbitrarily designed depending on the application.

会話用指向性赤外線信号受信部20と会話用指向性赤外線信号送信部28での信号は、信号検知部26により信号検知が行われている。   Signals from the directional infrared signal receiving unit 20 for conversation and signals from the directional infrared signal transmitting unit 28 for conversation are detected by a signal detection unit 26.

対話型赤外線通信装置10の使用を開始する場合は、まず、電源(図示せず。)をオンとして、呼出用指向性赤外線信号受信部12、信号変換部14、呼出部16と一連のブロックを制御する制御部18を駆動する。この状態で、お互いの装置の使用が準備される。   When the use of the interactive infrared communication device 10 is started, first, a power source (not shown) is turned on, and the calling directional infrared signal receiving unit 12, the signal converting unit 14, the calling unit 16 and a series of blocks are connected. The controller 18 to be controlled is driven. In this state, use of each other's devices is prepared.

そして、送信側はさらに、会話用指向性赤外線信号受信部20、出力音声変換部22、音声出力部24、信号検知部26、会話用指向性赤外線信号送信部28、入力音声変換部30及び音声入力部32の電源をオンして駆動状態とする。その後、呼び出したい相手に向かって音声入力部32から、音声を入力して、受信側である会話の相手に呼び掛ける。このとき、呼び掛けの音声は会話用指向性赤外線信号送信部28から、受信側に向かって指向性のある赤外線信号として送信する。   The transmitting side further includes a conversational directional infrared signal receiving unit 20, an output voice conversion unit 22, a voice output unit 24, a signal detection unit 26, a conversational directional infrared signal transmission unit 28, an input voice conversion unit 30, and a voice. The input unit 32 is turned on to be in a driving state. Thereafter, the voice is input from the voice input unit 32 toward the other party to be called, and the other party of the conversation on the receiving side is called. At this time, the calling voice is transmitted from the conversational directivity infrared signal transmitter 28 as a directivity infrared signal toward the receiving side.

受信側では、送信側の信号を4個の呼出用指向性赤外線信号受信部12−1〜12−4で受信可能な状態となっているから、指向性を有する呼出用指向性赤外線信号受信部12−1〜12−4のいずれかで呼出信号を受信する。例えば、呼出用指向性赤外線信号受信部A12−1で呼出信号を受信すると、信号変換部A14−1で信号変換され、呼出部A16−1を介して受信者に伝えられる。   On the receiving side, since the signals on the transmitting side can be received by the four calling directivity infrared signal receiving units 12-1 to 12-4, the calling directivity infrared signal receiving unit having directivity is provided. The call signal is received at any of 12-1 to 12-4. For example, when a call signal is received by the call directivity infrared signal receiving unit A12-1, the signal is converted by the signal conversion unit A14-1 and transmitted to the receiver via the call unit A16-1.

受信側が送信側からの赤外線信号を呼出用指向性赤外線信号受信部12で受信すると、制御部18により、会話用指向性赤外線信号受信部20、出力音声変換部22、音声出力部24、信号検知部26、会話用指向性赤外線信号送信部28、入力音声変換部30及び音声入力部32の電源をオンとする制御を行う。   When the reception side receives the infrared signal from the transmission side by the call directivity infrared signal reception unit 12, the control unit 18 causes the conversational directivity infrared signal reception unit 20, output voice conversion unit 22, voice output unit 24, signal detection. Control is performed to turn on the power of the unit 26, the directional infrared signal transmission unit 28 for conversation, the input voice conversion unit 30, and the voice input unit 32.

そして受信側は、呼出部16においてどの呼出部から呼出を受けているかが分かるから、送信側を見つけてその方向に向く。送信側を向いたときには会話用指向性赤外線信号受信部20と会話用指向性赤外線信号送信部の指向性の方向が送信側と一致してお互いの声を送受信できるから会話が可能となる。   And since the receiving side knows from which calling unit the calling unit 16 is receiving the call, the receiving side finds the transmitting side and faces in that direction. When facing the transmission side, the directivity directions of the conversational directional infrared signal receiving unit 20 and the conversational directional infrared signal transmission unit coincide with those of the transmission side so that voices can be transmitted and received.

信号検知部26では、会話用指向性赤外線信号受信部20と会話用指向性赤外線信号送信部28の入出力信号を検知しているから、何れからも信号が無いことを検出可能である。従って、信号が検出されない時間を予め定めておき、定められた一定の時間が経過しても信号検知部26において信号が検出されない場合は、制御部18により、対話型赤外線通信装置10の会話用指向性赤外線信号受信部20、出力音声変換部22、音声出力部24、信号検知部26、指会話用向性赤外線信号送信部28、入力音声変換部30及び音声入力部32の電源をオフとする制御を行う。この制御は、送信側及び受信側双方において行われる。この操作により消費電力の低減が図られる。
Since the signal detection unit 26 detects input / output signals of the conversational directional infrared signal reception unit 20 and the conversational directional infrared signal transmission unit 28, it can be detected that there is no signal from any of them. Accordingly, a time during which no signal is detected is determined in advance, and if no signal is detected by the signal detection unit 26 even after a predetermined time has elapsed, the control unit 18 uses the interactive infrared communication device 10 for conversation. The directional infrared signal receiver 20, the output voice converter 22, the voice output unit 24, the signal detector 26, the directional infrared signal transmitter 28 for finger conversation, the input voice converter 30 and the voice input unit 32 are turned off. Control. This control is performed on both the transmission side and the reception side. This operation reduces power consumption.

Example 1
FIG. 3 is a perspective view showing an embodiment in which the configuration of the block diagram shown in FIG. 2 is integrally mounted as a headphone adapter 36.

ヘッドフォン型アダプタ36は、音声出力部24として左右のヘッドフォン24−1、24−2を耳に当てる。マイクロフォンは音声入力部32となり、ヘッドフォン型アダプタ36を頭に装着したときには口の前に位置する。右のヘッドフォン24−1の上部には、会話用指向性赤外線信号送信部28が設けられている。ヘッドフォンのアーム上部には、会話用指向性赤外線信号受信部20と4個の呼出用指向性赤外線信号受信部12−1〜12−4が配置され、呼出部16−2、16−3は頭部表面に接するように配置されている。   The headphone adapter 36 applies the left and right headphones 24-1 and 24-2 as the sound output unit 24 to the ear. The microphone serves as an audio input unit 32 and is located in front of the mouth when the headphone adapter 36 is attached to the head. On the upper part of the right headphone 24-1, a conversational directional infrared signal transmission unit 28 is provided. A conversational directional infrared signal receiving unit 20 and four calling directional infrared signal receiving units 12-1 to 12-4 are arranged on the upper arm of the headphone, and the calling units 16-2 and 16-3 are connected to the head. It arrange | positions so that a part surface may be contact | connected.

図4は、主要部の具体的な機能ブロック図である。   FIG. 4 is a specific functional block diagram of the main part.

実施例で使用した呼出用指向性赤外線信号受信部品12−11、12−21、12−31、12−41と会話用指向性赤外線信号受信部品20−11は、高感度のフォトダイオードである10mm×10mmの大型フォトダイオード(浜松フォトニクス製S3590−01)を使用している。フォトダイオード自身での指向性はほとんど無いが、指向性を得るために金属の円筒を設けている。   The directional infrared signal receiving component 12-11, 12-21, 12-31, 12-41 for calling and the directional infrared signal receiving component 20-11 for conversation used in the example are 10 mm high-sensitivity photodiodes. A large photodiode of 10 mm (S3590-01 manufactured by Hamamatsu Photonics) is used. The photodiode itself has almost no directivity, but a metal cylinder is provided to obtain directivity.

図5に、金属円筒を設けて指向性赤外線信号受信部とした場合と、金属円筒を設けないで無指向性赤外線信号受信部とした場合の特性40を示した。測定データは、中心に受信部を設置し、発信機を徐々に近づけながら受信部が動作し始める距離及び角度を計測した。半径方向は受信距離である。指向性特性は、信号を発信した場合に、どの角度のどのくらい離れた位置から受信可能かを示している。金属円筒を設けて指向性赤外線信号受信部とした場合の特性42は、X方向に強い指向性を有しており、このX方向を特定の指向性を有する方向、あるいは顔の正面方向としている。一方、金属円筒を設けないで無指向性赤外線信号受信部として使用した場合の特性44は、わずかにY方向に指向性の偏りが見られるが、ほぼ全方向からの受信が可能な状態となっている。本発明においては、指向性を得るために長さ3〜5cm程度の金属円筒を使用している。指向性は金属円筒の長さによってカバーする角度を変えることが可能である。   FIG. 5 shows characteristics 40 when the metal cylinder is provided as the directional infrared signal receiver and when the metal cylinder is not provided as the omnidirectional infrared signal receiver. For the measurement data, a receiving unit was installed at the center, and the distance and angle at which the receiving unit started to operate while gradually approaching the transmitter were measured. The radial direction is the reception distance. The directivity characteristic indicates how far and at what angle a signal can be received when a signal is transmitted. The characteristic 42 in the case where a directional infrared signal receiver is provided by providing a metal cylinder has strong directivity in the X direction, and this X direction is a direction having a specific directivity or the front direction of the face. . On the other hand, the characteristic 44 when used as an omnidirectional infrared signal receiver without providing a metal cylinder shows a slight directional bias in the Y direction, but reception is possible in almost all directions. ing. In the present invention, a metal cylinder having a length of about 3 to 5 cm is used in order to obtain directivity. The directivity can change the covering angle depending on the length of the metal cylinder.

再度図4に戻って説明する。呼出用指向性赤外線信号受信部品12−11、12−21、12−31、12−41は、信号変換部14−1〜14−4として信号検出器14−11、14−21、14−31、14−41と音響制御部(PIC 12F683)14−12、14−22、14−32、14−42を備え、呼出用の振動器(16−11、16―21、16−31、16−4を振動させている。振動器16−11、16―21、16−31、16−4は、頭部表面に接するようにしてあり、図3に示した配置のように、前後左右のどの方向からの呼出かは、どの位置の振動器が振動しているかで容易に感知できる。会話用指向性赤外線信号受信部20には、出力音声の変換用としてFM復調器22−11が設けられており、音声信号に変換されてヘッドフォンに取り付けられたスピーカ32−11から可聴域の音声を発する。   Returning again to FIG. Calling directional infrared signal receiving components 12-11, 12-21, 12-31, 12-41 are signal detectors 14-11, 14-21, 14-31 as signal converters 14-1 to 14-4. , 14-41 and sound control units (PIC 12F683) 14-12, 14-22, 14-32, 14-42, and call vibrators (16-11, 16-21, 16-31, 16- The vibrators 16-11, 16-21, 16-31, and 16-4 are in contact with the head surface, and as shown in FIG. The conversational directional infrared signal receiving unit 20 is provided with an FM demodulator 22-11 for converting the output voice. And converted to audio signal headphones It emits a sound in the audible range from the attached speakers 32-11.

会話用指向性赤外線信号送信部品28−11は、Vishay社製の赤外LED TSFF5410を使用している。会話用指向性赤外線信号受信部品20−11と同様に、指向性を得るために金属円筒を使用して指向性を得ている。マイクロフォン24−11から音声を入力し、入力音声の変換用としてのFM復調器30−11は、話用指向性赤外線送信部品28−11に接続されている。   The directivity infrared signal transmission component 28-11 for conversation uses an infrared LED TSFF5410 manufactured by Vishay. Similar to the directional infrared signal receiving component 20-11 for conversation, the directivity is obtained by using a metal cylinder in order to obtain directivity. A voice is input from the microphone 24-11, and an FM demodulator 30-11 for converting the input voice is connected to the talking directional infrared transmission component 28-11.

ヘッドフォン型アダプタ36は、頭部にすべての機能部品を一体的に実装しており、顔の向きにより指向性の方向が決まる。このため、呼びかけられても自然な動作で会話が開始できる特徴を有している。
The headphone adapter 36 has all functional parts integrally mounted on the head, and the direction of directivity is determined by the orientation of the face. For this reason, it has the feature that conversation can be started with a natural motion even if called.

(実施例2)
図6は、図5に示したヘッドフォン型アダプタ36の構成要素のうち、会話用指向性赤外線信号受信部20と会話用指向性赤外線信号送信部28を、本体46から分離可能とした構造である。分離部48は、体の正面に取り付けが可能な取付部34を有し、配線35により本体46からの信号を送受信する。
(Example 2)
FIG. 6 shows a structure in which the conversational directional infrared signal receiver 20 and the conversational directional infrared signal transmitter 28 are separable from the main body 46 among the components of the headphone adapter 36 shown in FIG. . The separation unit 48 has an attachment part 34 that can be attached to the front of the body, and transmits and receives signals from the main body 46 via the wiring 35.

見通し距離で相手との会話を開始した場合、短い時間であれば相手を見ながら、すなわち、顔を背けずに会話が可能であろう。しかしながら、人間は、同じ体勢をずっと維持するのは難しく、例え目の前の相手と話している場合であっても、顔を背けたり、遠くを見たりいろいろな動作を伴うのが自然である。このような場合は、頭部に配置された会話用指向性赤外線信号受信部20及び会話用指向性赤外線信号送信部28の向きが変わって、会話ができなくなってしまう問題がある。そのために、本実施例のヘッドフォン型アダプタ36は、会話用指向性赤外線信号受信部20及び会話用指向性赤外線信号送信部28をヘッドフォン型アダプタ36から取り外し可能とする構造とし、本体46はそのまま頭部にあるが、分離部48は体の正面、例えば胸の位置に取り付けが可能な構造としている。取り外した会話用指向性赤外線信号受信部20及び会話用指向性赤外線信号送信部28は、相手を捜して正面を向き合い、会話が開始された後は、体の正面に設置できる用に取付部34を設けている。具体的には、会話用指向性赤外線信号受信部20及び会話用指向性赤外線信号送信部28を紐で繋いで、紐を首に掛けて胸の辺りに保持することにより、極めて簡単な構造で実現した。   When a conversation with the other party is started at a line-of-sight distance, it is possible to talk while looking at the other party, that is, without looking away, for a short time. However, it is difficult for humans to maintain the same posture all the time, and even when talking to the person in front of them, it is natural to turn away, look far away, and perform various actions. . In such a case, the direction of the conversational directional infrared signal receiving unit 20 and the conversational directional infrared signal transmitting unit 28 arranged on the head changes, and there is a problem that the conversation cannot be performed. For this purpose, the headphone type adapter 36 of the present embodiment has a structure in which the directional infrared signal receiving unit 20 for conversation and the directional infrared signal transmitting unit 28 for conversation can be detached from the headphone type adapter 36, and the main body 46 remains as it is. However, the separation part 48 has a structure that can be attached to the front of the body, for example, at the chest position. The removed directional infrared signal receiving unit 20 for conversation and the directional infrared signal transmitting unit 28 for conversation face each other in search of the other party, and after the conversation is started, the mounting unit 34 can be installed on the front of the body. Is provided. Specifically, the conversational directional infrared signal receiving unit 20 and the conversational directional infrared signal transmission unit 28 are connected by a string, and the string is hung around the neck and held around the chest, thereby having an extremely simple structure. It was realized.

人間の本来的な動作として、体の向きを一定に保つことはそれほど苦痛を感じないし、顔は、その場面により感情によっても様々な動作を行うものである。まして正面を向き続ける状態を維持することは、かなりの疲労も伴うものである。これらの問題は、実施に当たっては、会話用指向性赤外線信号受信部20及び会話用指向性赤外線信号送信部28を取り外し可能として、紐で繋いで首から下げて、体の向きと指向性の方向を一致させる手段により解決した。会話が終了したら、元に戻せばよい。
It is not so painful to keep the body orientation constant as an original human action, and the face performs various actions depending on the emotion depending on the scene. Furthermore, maintaining the state of facing the front is accompanied by considerable fatigue. In implementing these problems, the directional infrared signal receiving unit 20 for conversation and the directional infrared signal transmitting unit 28 for conversation can be removed, and are connected with a string and lowered from the neck, so that the direction of the body and the direction of the body It was solved by means to match.

FIG. 7 is a schematic diagram of the headphone adapter 36 according to the first embodiment when the bone conduction type headphone type adapter 50 adopting the bone conduction type earphone 54 and the bone conduction type microphone 56 as the earphone and the microphone is attached to the head 52. FIG. The bone-conduction earphone 54 is applied to the bone near the ear, and the bone-conduction microphone 56 is applied to the jawbone, each transmitting sound by vibration of the bone and picking up the sound. Clear noise can be transmitted and received without noise. Furthermore, unlike normal headphones, there is no need to cover the ears, and it is easy to wear for a long time even when there is no conversation. By adopting the bone conduction type earphone 54 and the bone conduction type microphone 56, the device becomes more convenient.

対話型赤外線通信装置10の使用頻度が高い場合は、常に装置を装着している必要がある。例えば、レストランでの注文システムで、カウンターで客からの注文を受けているような場合である。このような場合は、常に装置を装着して客からの注文を受けなければならない。長時間にわたりヘッドフォンを装着することは苦難を伴うこともある。このような場合にも骨伝導式のため、店内の雑音がカットされ、使用感の良い装置として長時間の使用にも適している。
When the interactive infrared communication device 10 is frequently used, it is necessary to always wear the device. For example, in an ordering system at a restaurant, an order from a customer is received at a counter. In such a case, you must always wear the device and receive orders from customers. Wearing headphones for a long time can be difficult. Even in such a case, because of the bone conduction type, the noise in the store is cut, and it is suitable for long-time use as a device with a good feeling of use.

図8は、呼出用指向性赤外線信号受信部12−1〜12−4、信号変換部(図示せず。)と呼出部16−1〜16−4を分離して呼出装置62とした実施例である。図8(A)に本体60、図8(B)に呼出装置62を示している。本体60はヘッドフォン型であり、実施例1と同様に頭部にセットする。呼出装置62での呼出部16−1〜16−4は、バイブレータの振動により音響を発する他、LED(Light Emitted Diode)等の発光素子を設けて、赤外線信号を受信したときに光を点滅させて、目視により送信者側の位置を知る。このように呼出装置62を分離することで本体60の軽量化が可能となる他、頭部に振動を受けることを好まない人に適する。また。目の前の机等に置いて使用することができるので、座っている場合や、車の中からの使用等の応用場面が考えられる。
Example 4
FIG. 8 shows an embodiment in which the calling directivity infrared signal receiving units 12-1 to 12-4, the signal converting unit (not shown), and the calling units 16-1 to 16-4 are separated into the calling device 62. It is. FIG. 8A shows the main body 60 and FIG. 8B shows the calling device 62. The main body 60 is a headphone type and is set on the head as in the first embodiment. The calling units 16-1 to 16-4 in the calling device 62 emit sound by vibration of the vibrator, and are provided with a light emitting element such as an LED (Light Emitted Diode) to blink the light when receiving an infrared signal. The position on the sender side is known visually. By separating the calling device 62 in this way, the main body 60 can be reduced in weight, and it is suitable for a person who does not like to receive vibration at the head. Also. Since it can be used by placing it on a desk or the like in front of you, it can be applied when you are sitting or using it from inside a car.

The conversational directional infrared signal receiving unit 20 and the conversational infrared signal transmitting unit 28 are provided in a direction orthogonal to the calling directional infrared signal receiving units 12-1 to 12-4. With this structure, when a call signal is received, the direction of the sender is visually recognized, and the voice input unit 32 at the top of the tabletop device 70 is brought to the mouth. The table-type device 70 changes from a state in which it is normally stationary, and the call directivity infrared signal receiving units 12-1 to 12-4 have directivity in the vertical direction, and the directivity for conversation. The infrared signal receiving unit 20 and the conversational infrared signal transmitting unit 28 have directivity in the horizontal direction. For this reason, an infrared signal is not received, and a conversation with only the conversation partner can be performed exclusively by a natural operation.

図11は、赤外線通信装置線10に、さらに会話用無指向性赤外線信号受信部21と会話用無指向性赤外線信号受信部29を加えたブロック図である。実施例1〜6では、会話は送信側と受信側の1対1の場面を想定した実施例であったが、必ずしも1対1である必要は無く、一人で複数の人に指示を出したり、複数の人からの指示を受けたりする場合もある。例えば、屋外での講習である、講師は複数の生徒に指示をだして、複数の生徒に音声を届けるが、生徒から向き合った場合にのみ音声の受信ができるような場面である。
(Example 7)
FIG. 11 is a block diagram in which a non-directional infrared signal receiver for conversation 21 and a non-directional infrared signal receiver for conversation 29 are added to the infrared communication device line 10. In the first to sixth embodiments, the conversation is assumed to be a one-to-one scene on the transmission side and the reception side. However, the conversation is not necessarily one-to-one, and one person can give instructions to a plurality of people. In some cases, we receive instructions from multiple people. For example, an instructor in an outdoor class is a scene in which an instruction is given to a plurality of students and audio is delivered to the plurality of students, but the audio can be received only when facing the students.

会話用指向性赤外線信号受信部20と会話用無指向性赤外線信号受信部21、及び、会話用指向性赤外線信号送信部28と会話用無指向性赤外線信号送信部29は任意に切り替え可能とすることにより、状況に応じた会話の形態が可能となり、応用範囲も広くなる。   The conversational directional infrared signal receiver 20 and the conversational omnidirectional infrared signal receiver 21 and the conversational directional infrared signal transmitter 28 and the conversational omnidirectional infrared signal transmitter 29 can be arbitrarily switched. As a result, a conversation form according to the situation becomes possible and the application range is widened.
