Hereinafter, the components will be described in order.

The wireless communication unit 110 includes one or more modules for enabling wireless communication between the glass type portable terminal 100 and the wireless communication system or between the glass type portable terminal 100 and the network in which the glass type portable terminal 100 is located can do. For example, the wireless communication unit 110 may include a mobile communication module 112, a wireless Internet module 113, a short distance communication module 114, a location information module 115, and the like.

The mobile communication module 112 may be coupled to a base station, an external terminal, or a server on a mobile communication network, such as, but not limited to, Gobal System for Mobile communications (GSM), Code Division Multiple Access (CDMA), Wideband CDMA Transmits and receives wireless signals with one. The wireless signal may include various types of data depending on a voice call signal, a video call signal or a text / multimedia message transmission / reception.

The wireless Internet module 113 is a module for wireless Internet access, and may be built in or enclosed in the glass-type portable terminal 100. Wireless Internet technologies include WLAN (Wi-Fi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access), GSM, CDMA, WCDMA, LTE Evolution (but not limited to) may be used.

The wireless Internet module 113, which performs wireless Internet access through the mobile communication network, is connected to the mobile communication module 110 through the mobile communication network, for example, from the viewpoint that the wireless Internet access by Wibro, HSDPA, GSM, CDMA, WCDMA, LTE, (112). ≪ / RTI >

The short-range communication module 114 refers to a module for short-range communication. Bluetooth, Radio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), ZigBee, and the like can be used as a short range communication technology.

According to the present technology, the GPS module calculates distance information and accurate time information from three or more satellites, and then applies trigonometry to the calculated information to obtain three-dimensional current position information according to latitude, longitude, and altitude It can be calculated accurately. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module can calculate speed information by continuously calculating the current position in real time.

1, the input unit 120 is for inputting an audio signal or a video signal. The input unit 120 may include a camera 121, a microphone 122, a user input unit 123, and the like.

The camera 121 processes an image frame 101 such as a still image or a moving image photographed by an image sensor in a video communication mode or a photographing mode. The processed image frame 101 may be displayed on the screen 151. [ The image frame 101 processed by the camera 121 may be stored in the storage unit 130 or may be transmitted to the outside through the wireless communication unit 110. Two or more cameras 121 may be provided depending on the use environment.

The microphone 122 receives an external sound signal through a microphone in a communication mode, a recording mode, a voice recognition mode, or the like, and processes it as electrical voice data. The processed voice data can be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 112 when the voice data is in the call mode, and output. Various noise reduction algorithms may be implemented in the microphone 122 to remove noise generated in receiving an external sound signal.

When the camera 121 acquires a still image, information can be extracted from the still image. Since the camera 121 is made up of a plurality of still images when capturing a moving image, it is unnecessary for the image recognition unit 125 to acquire information from the image recognition unit for all of the plurality of still images and to process the information in the control unit This can be a waste of process. Also, if unnecessary information is extracted and provided to the user, it may be inconvenient to use the glass-type portable terminal 100 worn with glasses.

The user can extract only necessary information through a voice command to press the user input unit 123 provided in the frame 101 or acquire image information, or the user can gaze at the same object for a predetermined time or more, Information can be extracted when the same image is photographed over a certain period of time.

Or when a user is close to a specific object, if the object is largely occupied in the field of view, it can be determined that the object is being watched. Accordingly, when one object of the image recognized by the camera 121 occupies more than a certain range of the image, information related to the object can be extracted.

The sensing unit 140 senses the state of the portable terminal 100 and the surrounding environment, and typically includes a gyro sensor 141 and an acceleration sensor 142.

The gyro sensor 141 is a device for detecting a change in tilt of the portable terminal, and detects variations in three orthogonal axes of x-axis, y-axis, and z-axis. Also known as an angular velocity sensor. It is possible to sense the tilt fluctuation of the main body of the mobile terminal by detecting the momentum of the rotational movement around each axis.

The conventional gyro sensor is in the form of a top having three axes, but recently it can be mounted on a small electronic product such as a mobile terminal by increasing its precision and miniaturizing its size, such as an optical gyro and a vibrating gyro. A six-axis sensor implemented by a MEMS module can also be used as the gyro sensor 141.

The gyro sensor 141 used in the present invention is not limited to the above-described type and includes all sensors capable of sensing the tilt and movement of the glass-type portable terminal 100.

The acceleration sensor 142 measures the dynamic force such as the acceleration of the glass-type portable terminal 100. It is also possible to detect vibrations, shocks, etc. from changes in acceleration. When an object with a mass is accelerated, a force is generated, so that a change due to the force is detected.

The proximity sensor 144 may be disposed in the frame portion and may sense an object close to the glass-type portable terminal. The proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or a nearby object without mechanical contact using the force of an electromagnetic field or infrared rays. The proximity sensor has a longer life span than the contact sensor and its utilization is also high.

Examples of the proximity sensor include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. And to detect the proximity of the pointer by the change of the electric field along the proximity of the pointer when the touch screen is electrostatic. In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Next, the output unit 150 is for generating an output related to visual, auditory or tactile sense, and may include a transparent screen 151 and an acoustic output unit 152.

The screen 151 is disposed in front of the user's eye and is similar to a lens of a pair of glasses. It is placed in front of the user's eyes and transparent so as to be able to see the objects on the front side, and text or images are displayed on the screen to provide information to the user.

A representative example of the transparent screen 151 is TOLED (Transparent OLED) or the like. The rear structure of the transparent screen 151 may also be of a light transmissive structure. With this structure, the user can see an object located behind the terminal body through the area occupied by the screen 151 of the terminal body.

The audio output unit 152 may output audio data received from the wireless communication unit 110 or stored in the storage unit 130 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, The sound output unit 152 outputs sound signals related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the glass-type portable terminal 100.

The storage unit 130 may expand the storage function using an auxiliary storage device such as an SD card as well as a built-in method.

The controller 180 typically controls the overall operation of the glass-type portable terminal. It can transmit and receive various signals or process input data by controlling the wireless communication unit, or control the screen 151 and the sound output unit to provide information to the user. The voice recognition unit 126 of the image recognition unit 125 may be configured as a part of the control unit 180. [

The control unit 180 of the present invention extracts information from the image acquired by the camera 121 and compares the extracted information with previously stored information based on the extracted information or stores the extracted information in the storage unit 130, ) And output the extracted information to the transparent screen 151 or retrieve the related information from the Internet.

The power supply unit 190 receives external power and internal power under the control of the controller 180 and supplies power necessary for operation of the respective components. The power supply unit 190 may include, for example, a battery, a connection port, a power supply control unit, and a charge monitoring unit. The battery may be an internal battery configured to be rechargeable, and may be detachably coupled to the frame 101 for charging or the like.
