Further features and advantages of the present invention will be further elucidated by the following detailed description of an embodiment thereof, with reference to the accompanying drawings. The attached drawings are as follows:
FIG. 1 shows a schematic block diagram of a human-computer interaction device according to an exemplary embodiment of the present invention; and
fig. 2 illustrates a schematic block diagram of a user terminal according to an exemplary embodiment of the present invention.
Detailed Description
In order to make the technical problems, technical solutions and advantageous effects of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and exemplary embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention. In the drawings, the same or similar reference numerals refer to the same or equivalent parts.
Fig. 1 shows a schematic block diagram of a human-computer interaction device 100 according to an exemplary embodiment of the present invention. The human-computer interaction device 100 comprises a control device 10 and at least one controlled device 30 which is in communication connection with the control device 10 and is controlled by the control device. The control device is configured to determine the position and orientation of the movable user terminal 200 and identify the controlled device 30, which the user terminal 200 is oriented or pointed, as an object manipulated by the user's voice instruction based on the determined position and orientation.
According to an exemplary embodiment of the present invention, the human-computer interaction device 100 can be used for voice-manipulating a plurality of controlled devices 30 in the same spatial region. For example, a plurality of vehicle-mounted devices as the controlled device 30 may be operated as the vehicle-mounted human-computer interaction device, and the vehicle-mounted devices include but are not limited to: vehicle air conditioner or ventilation unit, each door window, lighting device, door window lamp, car machine display screen, storage tank, trunk lid, each door. Alternatively, the human-computer interaction device 100 can also be used to operate a plurality of controlled devices in the same indoor space, such as a room or a public place (e.g., a mall). In this case, the controlled device 30 may be various electric appliances.
According to an exemplary embodiment of the invention, the user terminal 200 may be a wearable device, e.g. a head-mounted device, such as a headset, glasses, to be carried with the head of the user. In this case, the orientation of the earphone may generally represent the direction of the user's line of sight, and then, when the user wants to control a controlled device 30 by voice, the user can select the controlled device by naturally moving the head to look at the controlled device without performing other actions. Thereby, a "what you see is what you control" is achieved. For example, when a person speaks an "open window" or "close window" command when looking at a window, the window being looked at may be opened or closed; when a person wants to turn on a lighting device, he can look at the lighting device and say "turn on", i.e. light up the lighting device.
Additionally or alternatively, the user terminal 200 may be a device that is portable with or easily held by the user's upper arm or hand, such as: other wearable devices, such as bracelets, watches; a vehicle key; a mobile phone; a tablet computer; a dedicated control terminal. In this case, the user terminal 200 can select the controlled device 30 by pointing or pointing the controlled device 30 desired to be voice-controlled, thereby realizing "pointing, i.e., controlling".
Further, the control device 10 is configured to send a manipulation signal to the following controlled devices 30 in response to a voice instruction of a user: the controlled device 30 is the controlled device 30 toward or pointed to by the user terminal 200 when the voice command is issued. For this reason, the control device 10 needs to acquire the time at which the voice instruction is issued and further calculate the position and orientation of the user terminal 200 at that time.
The control device 10 utilizes the position and/or orientation data of the user terminal 200 measured by the sensor 220 in the user terminal 200 when determining the position and orientation of the user terminal 200. The sensors 220 are, for example: an accelerometer (such as a three-axis or six-axis accelerometer), a gyroscope (such as a three-axis or six-axis gyroscope), a magnetometer (such as a three-axis or six-axis magnetometer), or any combination thereof.
In the case where the human machine interaction device 100 is used for a vehicle, an in-vehicle sensor 20 for detecting the position and/or direction of the vehicle may also be disposed in the vehicle. In this case, the control device 10 may determine the position and the direction of the user terminal 200 within the vehicle based on the measurement result of the sensor 220 of the user terminal 200 and the measurement result of the in-vehicle sensor 20. The in-vehicle sensor 20 is, for example: an accelerometer (such as a three-axis or six-axis accelerometer), a gyroscope (such as a three-axis or six-axis gyroscope), a magnetometer (such as a three-axis or six-axis magnetometer), or any combination thereof.
Additionally or alternatively, a positioning device may be provided within the space, e.g. within a vehicle or a room, which positioning device is configured to be able to measure the position and/or distance of the user terminal 200 relative to the positioning device, wherein the position information of the positioning device within the space is pre-stored. The position information and measurement results of the positioning means may also be used to determine the position and orientation of the user terminal 200. Illustratively, the positioning device may be a depth camera.
According to an example, the onboard sensor 20 and/or the positioning device may be arranged at a central portion of the vehicle body. According to another example, the depth camera may be disposed near a front end of a roof of the vehicle toward the in-vehicle space.
The human-computer interaction device 100 further includes a storage device 40 communicatively connected to the control device 10, and the storage device 40 stores therein position information of each of the controlled devices 30, the position information being used by the control device 10 when determining the controlled device 30 toward which the user terminal 200 is directed or pointed.
For this purpose, the spatial environment may be modeled to form a three-dimensional model of the spatial environment including all the controlled devices 30, for example. In the case where the human-computer interaction device 100 is used for a vehicle, the environment inside the vehicle may be modeled at the time of shipment of the vehicle.
The human-computer interaction device 100 further comprises a voice input means 50 communicatively connected to the control means 10 for receiving voice input from a user. In response to the voice instruction of the user, the control device 10 generates a manipulation instruction for manipulating the recognized user terminal 200. In the case where the human-computer interaction device 100 is used in a vehicle, the voice input device 50 may be a microphone mounted on the vehicle.
Additionally or alternatively, the user terminal 200 may have a voice input device 250. In this case, the user terminal 200 may directly transmit the received voice signal to the human interaction device 100 without processing the voice signal received by the voice input means 250 to be processed by the control means 10. In this way, the structure of the user terminal 200 is simplified and the weight of the user terminal 200 is reduced.
According to an exemplary embodiment of the present invention, noise reduction means are provided for performing noise reduction processing on the received speech signal so that the user's speech instruction is clarified. For example, the noise reduction device may include a microphone array mounted on the vehicle, which in turn includes a plurality of microphones arranged at different positions of the vehicle. By means of these microphones, sound signals can be received from different locations of the vehicle for targeted noise reduction processing of the speech signals received by the speech input device 50 or 250. Additionally or alternatively, the noise reduction means may be integrated in the user terminal 200.
According to an exemplary embodiment of the present invention, the communication of the user terminal 200 with the control device 10, in particular, the communication from the user terminal 200 to the control device 10 may be an encrypted communication and/or a voiceprint communication. In this case, the decryption of the encryption and/or the voiceprint may be performed in the control device 10 or in a remote server.
According to an exemplary embodiment of the present invention, a speech recognition apparatus for recognizing a speech input of a user is provided. The voice recognition device may be integrated with the control device 10 (for example, mounted in a vehicle), or may be provided in a remote server.
According to an exemplary embodiment of the present invention, a specific orientation (e.g., an orientation of a specific component) of the user terminal 200 may be set as a nominal direction for pointing to the controlled device 30 desired to be manipulated. In the case where the user terminal 200 is an earphone, a direction pointing to the front of the user when the earphone is worn by the user may be set as a calibration direction. In the case where the user terminal 200 is a car key, the orientation of the tip of the car key may be set as the direction of the orientation of the car key. In the case where the user terminal 200 is a mobile phone, a tablet computer, or a dedicated manipulation terminal as will be explained in detail later, the orientation of the microphones of these devices may be set as the calibration direction.
According to an exemplary embodiment of the present invention, the user terminal 200 may have a mark therein or thereon, and the mark is used for indicating the calibration direction to the user. The marker is for example an arrow.
According to an exemplary embodiment of the present invention, the following devices may be identified as the controlled apparatus 30 toward or pointed to by the user terminal 200: the intersection of the device with the nominal direction. When there are a plurality of controlled devices 30 intersecting the calibration direction, the controlled device closest to the mobile terminal 200 in the calibration direction is identified as the controlled device 30 toward or pointed to by the user terminal 200.
In particular, in case the user terminal 200 is a wearable device that is carried along with the head of the user, a calibration procedure for calibrating the deviation between the gaze direction of the person and the actual orientation of the nominal direction of the wearable device is provided. The calibration procedure may be performed as: the user terminal 200 is led to sequentially look at different calibration positions according to the prompt, so that whether the calibration direction of the user terminal 200 intersects with the calibration positions when looking at each calibration position is determined, and when the calibration direction does not intersect with the calibration position, a compensation means is determined according to the deviation, and the determined compensation means can be stored and used for compensating the deviation of the orientation of the user terminal 200 relative to the sight line direction subsequently. In the case where the human machine interaction device 100 is used for a vehicle, for example, the calibration procedure may be performed such that a person sits at a fixed position (e.g., on a driver's seat) with the user terminal 200 to sequentially look at different points in the screen of the vehicle as prompted.
According to an exemplary embodiment of the present invention, the user terminal 200 has a data communication device configured to be able to exchange data with a communication device of the human-computer interaction device 100 by means of a communication protocol (e.g. WIFI), for example to transmit position and/or orientation data detected by the sensor 220 and voice data received by the voice input device 250 to the human-computer interaction device 100.
According to an exemplary embodiment of the present invention, the user terminal 200 is configured to wake up a voice control function of the controlled device 30 upon detecting an occurrence of a triggering event, the triggering event comprising at least one of:
the wake-up switch (physical switch or virtual switch) of the user terminal 200 is operated;
the display of the user terminal 200 is tapped;
-detecting a voice input from the user for waking up.
Only if the voice control function of the controlled device 30 is awakened, the voice command received by the controlled device 30 and the position and/or orientation data detected by the sensor 220 can be transferred to the human-computer interaction device 100 to manipulate the controlled device 300.
According to an exemplary embodiment of the invention, the user terminal 200 is configured to: when the user presses the switch of the user terminal 200, the voice input device 250 of the user terminal 200 receives a voice instruction of the user; when the user releases the switch, the received voice command is transmitted to the control device 10. The switch may be the same switch as the wake-up switch or a different switch.
According to an exemplary embodiment of the present invention, the user terminal 200 is configured to display the following voice control states by means of a display screen (e.g., a display screen of the user terminal or a display screen of the controlled device 300 or a car-in-vehicle screen):
-awakened, ready to be entered;
-is entering;
-understand input commands; and/or
-performing an operation.
Fig. 2 shows a schematic block diagram of an exemplary user terminal 200. In this example, the user terminal 200 is configured as a dedicated manipulation terminal.
The manipulation terminal 200 includes a touch screen 210, and a microphone hole 230 is disposed around the touch screen 210, and a microphone for receiving a user voice input is positioned behind the microphone hole 230. The manipulation terminal 200 is configured to: the manipulation terminal 200 may be awakened when the user taps the touch screen a preset number of times (e.g., two consecutive times).
Further, the user terminal 200 further comprises a sensor 220 and a data communication device for detecting the position and/or orientation of the user terminal 200 as described above.
Additionally, user terminal 200 also carries a battery, which may or may not be readily removable, and which may or may not be rechargeable.
According to an exemplary embodiment of the present invention, the user terminal 200 is configured and dimensioned to be held by a user. In particular, the user terminal 200 has a size similar to a credit card.
According to an exemplary embodiment of the present invention, the user terminal 200 is designed to be temporarily fixed to a vehicle as an accessory device of the vehicle.
