Description

  The present invention relates to a wireless device having both simplex communication and duplex communication functions, and more particularly to a wireless device that detects a state of a device by a sensor or the like and selects a communication method according to the state.

  Wireless communication by a wireless device can be broadly classified into two types, simplex communication and duplex communication. Simplex communication refers to a communication method in which transmission is alternately performed in opposite directions. In simplex communication, the wireless device basically stands by in a receiving state, and performs transmission only while, for example, a press talk button is pressed. That is, reception and transmission are performed alternately. Duplex communication refers to a bidirectional communication method in which both transmission and reception can be performed simultaneously. In duplex communication, since transmission and reception are performed simultaneously, it is necessary to reduce the output volume of the received audio signal in order to prevent howling and echo. In wireless communication, information is transmitted using a frequency band having a specific allocation. Thus, in order for more users to perform wireless communication simultaneously in an environment where the frequency band is limited, it is necessary to efficiently use the frequency band.

  Patent Document 1 discloses a related wireless device corresponding to such two types of communication methods, simplex communication and duplex communication. According to Patent Literature 1, a related portable wireless device includes a movable arm unit, and the arm unit includes a microphone, and a speaker according to a state where the arm unit is housed or pulled out by movement of the arm unit. Control the volume of the output. As a result, the related portable wireless device is switched to simplex communication when the microphone is stored, and switched to duplex communication when the microphone is pulled out. In duplex communication, the volume of the speaker is reduced to a level that cannot be heard without hearing.

  Wireless communication can be broadly divided into voice calls and videophones. As an example of a technology for switching between a voice call and a videophone communication method, Patent Document 2 describes a related portable terminal that can automatically and automatically switch between a voice call mode and a videophone mode. According to Patent Document 2, a related mobile terminal reliably determines whether the mobile terminal is near the user's ear by combining a distance sensor, a camera image face recognition process, and a camera image brightness measurement process. It is said. Note that the switching of the communication method is switching after the start of communication.

  However, in the related wireless device described in Document 1, the arm unit is opened and closed to switch the communication method. For this reason, there are cases where an unfamiliar user performs an incorrect operation or is obsessed with the operation even in an emergency situation where the user wants to communicate immediately. That is, since the arm portion is opened or closed depending on the communication method, there is a problem that the operation differs depending on the communication method.

  Further, in the related portable terminal described in Document 2, after starting communication as a voice call, the distance to the user, the on / off state of the camera, etc. are acquired, the communication method is determined based on them, and the necessary The system was switched accordingly. That is, since it is necessary to perform a communication method determination process between the start of communication and the start of a call, the frequency band is secured even though the call is not performed in the communication during that time. As described above, there is a problem that the communication method may be switched after the communication is started.

  As described above, the related wireless device described above has a problem that it is not possible to start a fixed communication with the same operation regardless of the communication method.

  An object of the present invention is to provide a wireless device and a control method therefor that solve the above-described problem that a fixed communication cannot be started with the same operation regardless of the communication method and the operability is not good. It is in.

  The wireless device of the present invention includes a sensor that acquires information regarding the relative position between the wireless device and the user, an input unit that receives an operation for starting communication, and a control unit that determines the state of the wireless device based on the information. The control unit uses the operation as a trigger to determine the relative position between the wireless device and the user, determines a predetermined communication method based on the determination, and then starts the predetermined communication method.

  The wireless device control method of the present invention acquires information on the relative position between the wireless device and the user, accepts an operation to start communication, determines the relative position between the wireless device and the user based on the information, Is used as a trigger to determine the state of the wireless device, determine a predetermined communication method based on the determination, and start the predetermined communication method.

  According to the wireless device and the control method thereof of the present invention, it is possible to start a confirmed communication with the same operation regardless of the communication method, and to improve the operability.

  Hereinafter, embodiments and examples of the present invention will be described in detail with reference to the drawings.

  In the following description, components having the same function may be denoted by the same reference numerals and description thereof may be omitted.

(Constitution)
FIG. 1 is a block diagram illustrating a configuration of a wireless device according to the present embodiment. The control unit 11 is a main control unit of the wireless device 10 and determines the state of the wireless device 10 from information on the relative position between the wireless device 10 and the user detected by the sensor 13 described later. This determination is performed using, for example, a communication start operation received from both the operation unit 14 or the microphone 15 as the input unit 20 as a trigger. Further, the control unit 11 selects a communication method from the determination result of the state of the wireless device 10. The control unit 11 controls the reception speaker 16 and the display unit 17.

  The wireless unit 12 communicates with other wireless devices based on information from the control unit 11. The wireless unit 12 has functions of both simplex communication and duplex communication.

  The sensor 13 detects information related to the state of the wireless device 10. More specifically, the information is related to the relative position between the wireless device 10 and the user. Examples of the sensor 13 include a proximity sensor, a motion sensor, and a camera. The proximity sensor detects whether the wireless device 10 is approaching the user by capturing a change in a magnetic field, a change in an electric field, reflection of infrared rays, reflection of ultrasonic waves, and the like. The motion sensor detects the moving distance and direction of the wireless device 10. The camera captures an image and determines the distance from the user by face recognition processing.

  The operation unit 14 is a button such as a numeric key switch that receives a user operation. The microphone 15 acquires ambient sound as input data. The receiving speaker 16 outputs the received voice data. The receiving speaker 16 is variable in volume by a volume adjustment function.

  FIG. 2 is an external view of the wireless device according to the embodiment. When performing simplex communication, the user supports the wireless device 10 in front of the face. At the time of transmission, a voice is input by speaking into the microphone 15 while pressing the press talk button 18. For this reason, the radio | wireless apparatus 10 is separated from the ear | edge at the time of simplex communication. In duplex communication, the user listens to the received voice output with the receiving speaker 16 close to the ear, speaks into the microphone 15 and inputs the voice.

  In the present embodiment, the wireless device having such a configuration detects a state of the device such as approaching or away from the ear and selects a communication method.

(Function)
FIG. 3 is a flowchart showing the operation of the wireless device of this embodiment. The sensor 13 periodically detects the state of the wireless device 10 (step S1). In order to start communication, the user supports the wireless device 10 in front of the face or in the vicinity of the ear, and presses an arbitrary button included in the operation unit 14 that is the input unit 20 of the wireless device 10, for example, a press talk button 18. (Step S2). The control unit 11 determines the relative position between the wireless device 10 and the user from the state information of the wireless device 10 input from the sensor 13 triggered by pressing the button 18 and an arbitrary threshold prepared in advance (step S3). .

For example, in step S3, the wireless device 10 if it is determined that close to the user selects a duplex communication (step S4). Next, each part including the radio | wireless part 12 is controlled (step S5), and communication is started (step S6).

Further, in step S3, the relative positions of the wireless device 10 and the user if it is determined that the away from the user selects a simplex communication (step S7). Next, each part including the radio | wireless part 12 is controlled (step S8), and communication is started (step S9).

  As described above, when the control unit 11 determines that the relative position between the wireless device 10 and the user is approaching the user, simplex communication is started, and the relative position between the wireless device 10 and the user is determined. If it is determined that the user is away from the user, duplex communication is started. As described above, the sensor 13 is used to detect the relative position between the wireless device 10 and the user. For example, when the sensor 13 is a proximity sensor, the control unit 11 determines whether or not the wireless device 10 is approaching the user based on information input from the proximity sensor 13 and a threshold value prepared in advance. Moreover, it can also be set as the structure calculated from the moving distance and the direction of movement of the radio | wireless apparatus 10 using a motion sensor etc. for the sensor 13. FIG.

  In addition, pressing any button on the operation unit 14 is a trigger for starting communication, but other operations may be used as a trigger. For example, if a voice input at an arbitrary level or more is used as a trigger, communication can be started instead of pressing the button of the operation unit 14, so that the trigger options are expanded. This further increases convenience.

  Further, although the description has been made on the time of outgoing call from the wireless device 10, the communication method can be similarly determined from the relative position between the wireless device 10 and the user at the time of incoming call.

In FIG. 3, the wireless device 10 steadily detects the state of the relative position between the wireless device 10 and the user, but is not necessarily stationary. For example, it is good also as a structure which starts the detection (step S1) of the state of an apparatus after the trigger input (step S2) of communication start.
FIG. 4 is a diagram illustrating a user operation on the wireless apparatus according to the present embodiment. FIG. 4A is a diagram illustrating an operation during simplex communication, and the relative position between the wireless device 10 and the user is approaching the user. FIG. 4B is a diagram illustrating an operation during duplex communication, and the relative position between the wireless device 10 and the user is far from the user.
(effect)
This embodiment has both simplex communication and duplex communication functions, and by configuring as described above, a wireless device with high operability that can start communication with the same operation regardless of the communication method is realized. Can do.

  Further, since communication is started after the communication method is confirmed, the confirmed communication can be started with the same operation regardless of the communication method, and the operability can be improved.

  In this embodiment, which has both simplex and duplex functions, it is assumed that the terminal is located away from the ear during simplex communication. It is conceivable that the volume of the speaker 16 is set to be higher than that during communication. For this reason, when an ear is brought close to the speaker 16 at the time of simplex communication, there is a possibility of feeling uncomfortable. However, in this embodiment, even when the wireless device is brought into close contact with the ear when receiving simplex communication, the state is detected and switched to duplex communication, so that there is no unpleasant feeling due to excessive volume.

The present invention includes, as a minimum configuration, a sensor that acquires information related to a relative position between a wireless device and a user, an input unit that receives an operation for starting communication, and a control unit that determines the state of the wireless device based on the information. If it is provided, the above-described operations and effects can be achieved. That is, regardless of the communication method, the confirmed communication can be started with the same operation, and the operability is improved.

  The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the invention described in the claims, and it is also included within the scope of the present invention. Not too long.
