The terminal device of the reception object person receives the request of the response and the distance level information, and generates or attenuates the vibrations of strength corresponding to the distance level information.

Description

  The present invention relates to a communication establishment method, apparatus, and program, and more particularly to induce communication such as making an unspecified transmission such as a conversation by a terminal device not equipped with a portable display such as a transceiver. The present invention relates to a communication establishment method, apparatus, and program for a service in Japan.

  To start communication, specify the person you want to communicate with by specifying your phone number, e-mail address, etc., and direct access that allows you to access efficiently, and select a person who can select the communication according to the new encounter and the situation of the other party. There is moderate access.

  The present invention is intended for gentle access.

As an example, there is a wireless transceiver as an old loose access.
The conversation starts when the caller calls someone and there is a response from the recipient. The other party can end without knowing its existence, can start communication gradually, can end communication halfway and disappear without being tracked. However, the wireless transceiver has a problem that the conversation after the partner is decided is more restricted than a telephone or the like, and there is a problem that the physical distance to the partner cannot be used.

  Therefore, in recent years, there has been a push-to-talk (PTT) service as a service fused with a mobile phone similar to a radio. This also enables communication over distances for multiple members. However, physical distance cannot be used for communication. On the other hand, what has the function which can display a member's positional information on a map also appears as an extension of PTT service combining the above (for example, refer patent document 1).

  However, services that require a display have problems such as lowering the degree of design of the terminal and design freedom, increasing costs and increasing the risk of failure, and difficulty in considering users who are not good at maps and those who are visually impaired.

In addition, there is a privacy problem that the position of the participant is specifically displayed in advance.
When displaying the position of a member in advance, it is difficult to reflect the circumstances of the other party. Or the confirmation phase of whether transmission of position information is permitted beforehand is needed, and a procedure becomes troublesome.

  However, as a new service, there is a need for a system that transmits only a sense of distance without telling each other's exact location, recruits anonymous communication participants, and allows nearby participants to participate in communication more advantageously. Yes.

  At that time, the target is a child or an elderly person, and there are various layers for each service, and he does not want to use the display for reasons such as activity, visual problems, design, cost, etc. There was also a request.

JP 2008-182612 A

  As mentioned above, you can feel a sense of physical distance from the other party and do not require the use of detailed visual information. In the past, there was no prior art that could freely choose whether or not to convey its existence.

It is a system configuration diagram of the present invention. 2 is a sequence chart according to the first embodiment of the present invention. It is a sequence chart in the 3rd Embodiment of this invention. It is a figure for demonstrating a Doppler sound. It is the example which incorporated the some speaker in the 5th Embodiment of this invention. FIG. 2 is a diagram for explaining a first embodiment of the present invention.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a system configuration according to an embodiment of the present invention.

  The system shown in FIG. 1 includes a plurality of terminal devices 1100 and 1200, one center system 1900, and a wired or wireless network 1800 connecting them.

  Although there are N devices as terminal devices, in the present embodiment, description will be made as a sender A side terminal device 1100 and a receiver B side terminal device 1200. Since terminal devices 1100 and 1200 have the same configuration, only the configuration of terminal device 1100 will be described below.

  The terminal device 1100 includes a communication unit 1101, a control unit 1102, an illumination unit 1190, an acoustic unit 1191, a vibration sensor 1192, and an input unit 1193. Although not shown, it has a position information search function (for example, GPS) for searching the position of its own device, and the acquired position information is registered in the center system 1900 via the communication unit 1101.

  The center system 1900 includes a control unit 1910, a communication unit 1920, a user location management DB 1930, and a group management DB 1940. The group management DB 1940 stores information in which user group IDs are associated with user IDs. The user location management DB 1930 stores location information registered from the caller A side terminal device 1100 and the caller B side terminal device 1200, and is updated each time the location information is received.

  The above configuration is common to the following embodiments.

  The operation in the above configuration will be described below for each case.

<First embodiment>
FIG. 2 is a sequence chart according to the first embodiment of the present invention.

  When the caller A gives a vibration of a certain level or more to the vibration sensor 1192 of the caller A side terminal device 1100 from the input unit 1193, the vibration sensor 1102 detects the vibration (step 101) and information ( A signal including a message, position information, maximum distance, etc.) and a user ID is transmitted to the center 1900 via the communication unit 1101 and the network 1800 (step 102).

  The communication unit 1920 of the center system 1900 receives the signal (step 103), and the control unit 1910 refers to the user location management DB 1930 based on the user ID and specifies the location of the user (step 014). In the present embodiment, the user position is acquired from the user position management DB 1930. However, the present invention is not limited to this example, and the position information is transmitted to the center 1900 together with the user ID from the calling side A terminal apparatus 1100. May be.

  Based on the user ID registered in advance, the control unit 1910 of the center system 1900 refers to the user ID location management DB 1930 to determine the distance between the terminal device 1200 of the recipient and the caller A terminal device 1100. Based on the obtained location information of the user, the maximum distance d between the caller position and the recipient is minimized (step 105), and the sender and the unsent recipient who exists within the maximum distance d are specified. (Step 106). Here, when specifying unsent recipients, for example, send to everyone at distance level 1, and to everyone except distance sent from everyone within 5 km at distance level 1 send. In the case of distance level 3, processing is performed such as sending to everyone except those who have sent to distance levels 1 and 2 from everyone within 10 km. In order to manage who sent it, it is possible to use a flag or a temporarily held table.

The communication unit 1920 transmits a request for a response and a distance level to the identified terminal device 1200 of the person to be received simultaneously or sequentially (step 107). As a distance level, for example,
・ Distance level: Within 1 km ・ Distance level 2: Within 1 to 5 km ・ Distance level 3: Within 5 to 10 km ・ Distance level 4: It shall be preset as 10 km or more.

  The control unit 1910 performs WAIT according to the maximum distance d with the caller (step 107). Generally, the WAIT time is a constant or a constant corresponding to the distance. The process of increasing the maximum distance d by increasing is repeated until the maximum distance d with the caller exceeds a specified value (step 108).

  The receiver B side terminal 1200 receives a response request from the center system 1900 in the communication unit 1201 (step 109). The control unit 1202 generates a vibration having a strength corresponding to the distance level included in the response request, and attenuates the strength of the vibration according to the distance level (step 110). For example, as described below, a distance level and a vibration intensity are set in advance in a memory (not shown), and a vibration corresponding to the distance level is generated.

・ Distance level 1: Vibration intensity ... 3
・ Distance level 2: Vibration intensity ... 2
・ Distance level 3: Vibration intensity ... 1
・ Distance level 4: Vibration intensity ... 0
The sound part 1291 reproduces the message included in the response request (step 111). If it is time-out, the communication is terminated, and if the vibration sensor 1292 detects reaction vibration (step 113, Yes) before the time-out (step 112, No), a request is transmitted (step 114).

This makes it possible to send messages to recipients who are close to each other faster,
The closer you are, the faster (advantageous) you can react to the message. In addition, it is possible to provide a service that makes use of a sense of distance that does not exclude the expression of participation even if you are far away.

<Second Embodiment>
In the present embodiment, a method for notifying the receiver B via sound when a response request is received by the terminal device 1200 on the receiver B side will be described.

  When the terminal device 1200 on the receiver B side receives the response request, the control unit 1202 generates and attenuates vibration according to the distance level with respect to the vibration function. Instruct to generate sound. At this time, the control unit 1202 transfers the distance level to the sound unit 1291 so that the sound unit 1291 amplifies or attenuates the sound intensity according to the distance level. Alternatively, it is possible to generate the sound a plurality of times, and to increase the generation interval of the plurality of times according to the distance (distance level) between the sender and the recipient, or to combine them.

  For example, the control can be performed by setting in the memory as follows.

・ Distance level 1: Vibration intensity ... 3, Volume ... 3, Frequency ... 6, Sound generation interval ... 1 second ・ Distance level 2: Vibration intensity ... 2, Volume ... 2, Frequency ... 4, Sound generation interval ... 3 second Level 3: Vibration intensity ... 1, Volume ... 1, Number of times ... 3, Sound generation interval ... 4 seconds Distance level 4: Vibration intensity ... 0, Volume ... 1, Number of times ... 2, Sound generation interval ... 5 seconds For example, if the subject sounds a bell with vibration and the distance from the caller is close, the sound of the bell will sound without interruption. If the distance from the caller is far, the sound of the bell will sound and calm down. In addition, by repeating that the sound of a bell sounds and calms down, it becomes possible to transmit a sense of distance even with sound.

<Third Embodiment>
In this embodiment, an example in which light is emitted using the lighting unit 1290 according to the distance level will be described.

  FIG. 3 is a sequence chart according to the third embodiment of the present invention. The same operations as those in FIG. 2 are denoted by the same step numbers, and the description thereof is omitted.

  When the terminal device 1200 on the receiver B side receives the response request, the control unit 1202 first causes the illumination unit 1290 to emit light (step 201), and then performs the operation described in the second embodiment. Do.

  As a result, it is possible to understand the urgency intuitively by receiving light first, then receiving vibration and sound, and receiving subsequent vibration and sound. It becomes easy to pay attention to and can reduce cognitive leakage.

<Fourth embodiment>
In the present embodiment, an operation for limiting the direction of presence of the reception target will be described.

  The center 1900 detects the direction of the sender A terminal device 1100 and each of the recipients 1200, 1300, 1400,..., And sends a response request with the direction limited when the recipients are specified.

  In this case, the terminal device 1100 on the caller side is limited by determining the direction to be limited based on the positional relationship between itself and the terminal device, or by sliding the terminal itself on the floor surface (flick input). Determine the direction.

  This realizes communication establishment using distance and direction.

<Fifth embodiment>
In this embodiment, a case where the Doppler effect is added to the above-described embodiment will be described.

  When receiving the response request, the terminal device 1200 of the reception target person causes the sound unit 1291 to generate a sound corresponding to the distance level. At this time, according to the method of the fourth embodiment described above, the center 1900 detects the direction of the terminal device of the sender A-side terminal device 1100 and each of the recipients 1200, 1300, 1400,. Information is transmitted to the target terminal along with the distance. The sound unit 1291 of the terminal 1200 (1300, 1400,...) Of the person to be received generates a sound that reproduces the Doppler effect by approaching the sound from the direction of the caller and moving away from or toward the opposite side of the caller. To do. Note that the acoustic unit 1291 is provided with a mechanism for generating Doppler sound effects based on distance level and direction information in advance. As shown in FIG. 4, the Doppler sound is such that when the generation source approaches, the vibration of the wave is reduced and the frequency is increased, and when the source is moved away, the vibration is increased and decreased. Note that the Doppler sound recorded in advance or generated on the spot is output from the sound unit 1291.

  As a result, the reception target person can intuitively grasp the direction of the requester by obtaining the same sound effect as the situation in which an ambulance heading in the direction of the injured person passes by everyday. Or you can enjoy the feeling of the wind passing through you and the sound of the wind chimes passing from the windward to the windward.

  As a result, the reception target person can obtain the same sound effect as the situation in which an ambulance heading in the direction of the injured person passes by everyday, and can intuitively grasp the direction of the requester. Or you can taste the feeling of the wind passing through you, the feeling of the wind chimes passing from the windward to the windward.

  In addition, it is easy to distinguish even if a plurality of messages come at the same time. For example, as shown in FIG. 5, it is possible to recognize the direction by configuring the wand equipped with the device so that a plurality of speakers are built therein. In the example of FIG. 5, the first half of the waveform α is output from the speaker D closest to the approaching direction in the time interval 1, and the second half of the waveform α is output from the speaker B closest to the moving away in the time interval 2.

<Sixth Embodiment>
In the present embodiment, a case where a sound transmitted from the center 1900 is reproduced will be described.

  In the above embodiment, an example in which the center 1900 performs sound generation and control on the terminal side has been described. However, in this embodiment, control on the terminal side is performed on the center 1900 side. In 1291, the sound acquired from the center 1900 is reproduced.

  The center 1900 is a control signal for generating / reproducing Doppler sound that outputs and emits sound when the terminal receives the distance level and direction information, which has been performed on the terminal side. Is sent to each target person's terminal.

  Thereby, the terminal device 1200 of the person to be received receives these control signals, and the illumination unit 1290, the sound unit 1291, and the vibration function are activated.

  As a result, various sounds that are not limited to the terminal of the person to be received can be transmitted as a message. For example, it becomes easy to transmit the caller's voice itself such as “Someone, please help!” In an emergency report.

<First embodiment>
In this embodiment, an example in which the present invention is applied to a school excursion will be described.

  In school excursions, if the teacher monitors the student's behavior with the GPS function of the mobile phone, the student may turn off the mobile phone power after monitoring. However, if the present invention is used, it becomes possible for a student to communicate as necessary while easily understanding the sense of distance from the teacher without monitoring the detailed position information by the teacher. In addition, teachers and students can enjoy communication and create communication.

  For example, in FIG. 6, it is assumed that the sender is a teacher and the recipients are students' group A, B, C, D, E. In FIG. 6, distance level 1 is 1 km, distance level 2 is 5 km, level 3 is 10 km, and level 4 is higher.

Group A is now in distance level 1, Group B is in distance level 2, Group C and Group D are in distance level 3, and Group E is in distance level 4.

  At this time, a message “How are you ?!” is input from the input unit 1193 of the terminal 1100 owned by the teacher by any method or recording, and is transmitted to the center 1900 with vibration. The center 1900 receives the request, first identifies the subject A group within the distance level 1, and sends the message “How are you ?!” and the distance level = 1 to the terminal device possessed by the group A. This time is T0. The terminal of the group A that has received the message, corresponding to the distance level = 1, reproduces “How are you ?!” three times in succession.

  Next, the subject person B group within the distance level 2 is specified, and after T0 + 3 seconds, the message “How are you ?!” and the distance level = 2 are sent to the terminal device of the group B. The terminal of the group B that has received the message, corresponding to the distance level = 2, reproduces “How are you ?!” three times at intervals of one second.

  Next, the subject C group and D group within the distance level 3 are specified, and after T0 + 6 seconds, the message “How are you ?!” and the distance level = 3 are sent to each terminal device of the C group and D group.

  The terminal of the group B that has received the message, corresponding to the distance level = 3, reproduces “How are you ?!” three times at intervals of 2 seconds.

  Finally, the target person E group within the distance level 4 is specified, and after T0 + 9 seconds, the message “How are you ?!” and the distance level = 4 are sent to each terminal device of the E group. The terminal of the group E that receives the message plays back “three times” at 3 second intervals corresponding to the distance level = 4.

  In this way, messages can arrive earlier in the closest order, so that a group that is close to sending a response message can do it quickly. In addition, each group can confirm the sense of distance from the teacher's position by the widening of the interval when the message from the teacher “How are you ?!” continues.

  At this time, as shown in the third embodiment, all terminals may emit light and alert at the timing of T0.

  Further, as shown in the fourth embodiment, the teacher may deliver a message limited to only the north side by flicking (sliding) the terminal to the north side. In that case, the message does not reach Group B and Group D that are off the north.

  As for the response to the teacher, for example, Group A can transmit the message “Group A is fine” to all members including the teacher using the same mechanism, applying the fifth embodiment, If the direction of the teacher can be confirmed, it is possible to apply the fourth embodiment and return a response only in that direction.

<Second embodiment>
In this embodiment, a case where the present invention is used for issuing an emergency message will be described.

  For example, suppose you suddenly feel unwell and want to seek help from someone nearby. If this invention is used at this time, it will become possible to ask a wide range of subjects for help.

At this time, if a message “Someone, please help me !?” is input by an arbitrary method or recording from the input unit 1193 at the terminal 1100 possessed by the suddenly ill person, and the center 1900 receives the request, First, a subject group within the distance level 1 is specified, and a message “Someone, please help me!” Is sent to the terminal device of the subject group as a distance level = 1. This time is T0.
Each terminal that receives the message, corresponding to the distance level = 1, plays “someone, please help me!” Three times in succession.

Next, the subject group within the distance level 2 is specified, and after T0 + 3 seconds, the message “Someone, please help me!” Is sent to the terminal device of the subject group as the distance level = 2.
Each terminal that receives the message corresponds to the distance level = 2 and plays “someone, please help me!” Three times at 1 second intervals.

  The above processing is repeated as necessary. In this case, a nearby person can preferentially react.

  Thus, in an emergency situation, the location of the caller and the user ID may be notified together with the message “Someone please help me !?”.

  In such a case, a person who can determine that he / she is nearby and can react to the SOS can rush to the spot. Furthermore, even if you are nearby, you can ignore it, and no one will be attacked about it, and if you are far away, the situation (for example, in a low-population area) Depending on the situation, it will be possible to rush, establish communication and select.

  It is also possible to use this method to approach at that time or to confirm whether someone is approaching.

  For example, when the rescuer returns the message “Where are you !?” in the same framework, as shown in the fifth embodiment (or from the beginning), the presence direction of the caller is communicated. It is possible to use a mechanism that can.

  Moreover, it becomes possible to alert the emergency message by transmitting light first using the third embodiment.

  In addition, the present invention can also be used in games such as waiting, orienteering in the field, and playing games.

  The recipient may be an unspecified number such as an urgent message or a member belonging to a specific group or condition such as a school trip student.

  The message input device is not particularly limited, and other existing technologies may be used.

The maximum reach distance, repetition interval, etc. may be changed according to the characteristics of application.
Also, the caller side may specify.

  The caller location may be periodically captured on the center side or transmitted to the center together with a message.

  It is also possible to construct the operation of the above-described terminal device and center components as a program and install it on a computer used as the terminal device and center device to execute it, or distribute it via a network.

  The present invention is not limited to the above-described embodiment, and various modifications and applications can be made within the scope of the claims.
