- a non-powered terminal (1) further provided with an ID memory (15a) as a modulation circuit (16a) as a modulation means (16), and an infrared sensor (41) on the environment side.
- the ID detection device (4) has been newly installed.
- the non-powered terminal (1) transmits the ID infrared light modulated by the modulation circuit (16a) according to its own ID data stored in the ID memory (15a) to an infrared beacon ( From 14a), light is emitted intermittently at preset time intervals.
- An infrared LED can be used as the infrared beacon (14a).
- this infrared light for ID passes through two different sensors, namely, an infrared sensor (41) of the ID detection device (4) and an infrared camera (41) of the position detection device (3). 32 a) is reached.
- the infrared sensor (41) receives the modulated infrared light for ID, demodulates it, and extracts an ID bit sequence.
- the infrared light for ID is captured and captured as a bright spot, and based on the image, the position relative to the camera is detected from the frame coordinates through the position detector (33a) by image processing.
- the output timing can be known from the change in the luminescent spot. That is, it is possible to synchronize the output of the infrared sensor (41) with the camera image by the infrared camera (32a). You can.
- infrared light for position is constantly emitted from the infrared LED (3 la), and when a non-powered terminal (1) enters the emission range and turns to the emission direction, recursion occurs.
- the positioning infrared light is reflected by the mold reflection sheet (13a) in substantially the same direction as the incident direction.
- the infrared light for position from the retroreflective sheet (13a) is retroreflected to the infrared camera (32a) located close to the infrared LED (3la).
- the recursive reflection sheet (13a) can be composed of, for example, a plurality of recursive corner cubes arranged in a sheet.
- the infrared camera (32a) captures the infrared light for position as a bright spot through a visible light cut filter, and based on this image, detects the relative position of the camera from the frame coordinates through the position detector (33a) by image processing. You.
- the bright spot of this position infrared light, that is, the retroreflective sheet (l'3a) is unlikely to be lost unlike the ID infrared light, that is, the infrared beacon (14a).
- the position can always be tracked. Therefore, if the bright spot of the infrared beacon (14a) appears near the bright spot of the retroreflective sheet (13a), the ID obtained by the infrared sensor (41) is used as the ID of the retroreflective sheet (13a). a) can be assigned.
- load detection is performed by time-series processing using an infrared sensor (41) for ID detection and image processing using an infrared camera (32a) for position detection. Processing can be performed with a lower load than in the case of detection.
- Fig. 4 shows the bright spots of the infrared light for positioning from the retroreflective sheet (13a) in the image captured by the infrared camera (32a) (slightly larger lower bright spots in the white frame. (The shape is almost visible) and the bright spot of the ID infrared light from the infrared beacon (14a) (small round upper bright spot in the white frame. The shape of the LED beacon is almost visible).
- IDs are associated with the infrared sensor (41), and it can be detected that the non-powered terminal (1) having the ID number 65 is at the detected position.
- the carrier frequency of the beacon is sufficiently higher than the frame period of the camera, and one sequence of the beacon is sufficiently longer than the frame time of the camera. Then, the camera can detect the beacons as bright spots. On the other hand, since the reflected light from the reflection sheet is continuous light, it can be detected regardless of the frame period and time, and the larger bright spots around the beacon are those of the reflection sheet.
- the approximate distance between the infrared camera (32a) and the non-powered terminal (1) can be calculated based on the size of the bright spot on the reflection sheet. Therefore, if the distortion of the camera lens is corrected for the captured image, the position of the beacon can be detected.
- the frame time is about 33 ms. Beacons can be imaged stably if the sequence time is at least 66 ms, which is twice this.
- the beacon uses its own ID, for example, PPM (Pulse Phase Modulation) Pulse modulation such as PWM (Pulse Width Modulation) is performed, and the modulated signal is mounted on a carrier wave of, for example, 38 kHz and transmitted by infrared light.
- PPM Pulse Phase Modulation
- PWM Pulse Width Modulation
- the sensor extracts a pulse from the carrier wave, demodulates the pulse based on its temporal position, and extracts a bit string as ID.
- ID can be detected.
- the infrared sensor (41) is a single light receiving element, it can receive only one beacon at a time.
- multiple beacons are generated at the same time, they collide and mix the waveforms, causing an error in the physical carrier or the modulation layer above it, and cannot demodulate. Therefore, if a collision occurs, the wrong ID is not detected, but none of the colliding beacons can be received correctly.
- the collision can be detected on the sensor side. Therefore, if the time interval of intermittent light emission is made random, that is, the output timing of the beacon is made random, it is possible to correctly detect D under a certain establishment according to the number of users, that is, the number of terminals.
- the beacon outputs of the two non-powered terminals (1) are synchronized and they collide, Considering the case, the collision can be detected on the sensor side, so the wrong ID is not detected. Since the next beacon output is random, the probability that the next transmission will be synchronized is extremely small if the inter-invalve time is long enough for the beacon sequence time. Therefore, by taking the average interval time between beacon outputs to be sufficiently long with respect to the sequence time of the beacon while considering the number of terminals, the ID of each is correctly set after the interval time. It can be detected. If the ID can be detected, the terminal can be tracked as long as the bright spot of the reflection sheet obtained by the camera imaging is not lost, and the subsequent collision can be ignored. As a result, even if multiple users enter the same area and the infrared light for ID is synchronized from each non-powered terminal (1), the ID information and the position information of each user can be accurately determined. Can be associated with.

For example, when the ID is pulse-modulated and transmitted on a carrier wave and transmitted by infrared light, the response signal is separately pulse-modulated and transmitted on a carrier wave having a different frequency.
- the infrared light is received by the infrared sensor (41) or a separate infrared sensor dedicated to response infrared light, and demodulated to obtain a response signal.
- the user can receive the audio information as instructed by changing the audio information to be transmitted according to the extracted response signal.
- the environment side detects the location information and ID information of the non-powered terminal (1) that sent the response signal, and based on that information, provides pinpoint and accurate inactivity. Personal support can be achieved.
- response information rewriting signals to the CPU and memory together with voice information from the environment
- response information that can be transmitted by operating each response button (110) (1 1 1) for each inquiry signal is changed. By doing so, it is possible to realize more informed information support.
- a button battery (18) is used as the driving power source.
- a solar cell (11a) may be directly connected and its generated DC component may be used.
- a secondary battery or the like for storing the power may be provided to use the stored power.
- buttons (1 10) and (11 1) are provided, but one or more than two response buttons may be provided.
- the minimum intention here is to realize a simple communication of intention by the user.Considering this, even if there are too many buttons, it becomes too complicated and power consumption increases. It can be said that it is preferable to suppress the number to one, two, or several. However, it is needless to say that the number is not limited.
- the power-supply type non-powered terminal (1) is used,
- staff cards used in various situations, such as event venues can be used as card-like objects such as pass cards, membership cards, ID cards, etc.
- it can be used as a powerless terminal (1).
- (1 13) in FIGS. 7 and 8 indicates an ID display such as a business card of the user on the surface.
- the non-powered terminal (1) in the invention of the present application is an earphone.
- the information support system of the invention of the present application not only the position information of the user terminal but also the ID information can be simultaneously detected, and based on the detection result, the user's individual information support is provided. It will also be possible to realize better interactive support between the environment and the user.
