Description

The present invention relates to an electric field communication device and a pedestrian guidance device used for guiding a pedestrian to a certain destination using electric field communication technology.

  Wearable computers are attracting attention due to the miniaturization and high performance of portable terminals. FIG. 9 shows an example in which such a wearable computer is worn on a person and used. As shown in FIG. 9, wearable computers 107 are attached to human arms, shoulders, torso, etc. via transceivers 109 to transmit and receive data to each other and to touch walls and floors so that they can be touched by the tips of limbs. Communication is performed with a personal computer (PC) 108 provided outside via the provided transceivers 109a and 109b and a cable.

  The transceiver 109 used for data communication between the wearable computer 107 and between the wearable computer 107 and the PC 108 uses a signal detection technique based on an electro-optic technique using laser light and an electro-optic crystal, and transmits the data. An electric field based on information to be induced is induced in a living body which is an electric field transmission medium, and information is transmitted and received using the induced electric field. Such communication is called electric field communication.

  In the field of electric field communication, for example, as described in Japanese Patent No. 380463 (Patent Document 1), a suspicious person's premises and residences are utilized by using a planar electric field communication electrode and a transceiver that performs electric field communication. There is known a suspicious person detection system that accurately detects entry into a room and entry into a room.

  However, this conventional technique is intended to detect a suspicious person and does not have the purpose of guiding a general pedestrian to a certain destination. The electrode has no light emitting function.

On the other hand, in a dark corridor, it is desirable to install a device that emits light and guides the floor to notify the correct walking direction. However, it is desirable to have a pedestrian guidance device that emits light only when a pedestrian is actually walking, and guides it to a destination location with a guide light that is always lit. If such a pedestrian guidance device can be realized by applying electric field communication technology developed in recent years, it is possible to well meet social demands for power saving and energy saving.

The thickness of the entire face material is less than about 7 mm.

  Next, the operation of the electric field communication apparatus having the above configuration will be described. The electric field communication apparatus having the above configuration can be used by being installed on a floor or a wall in front of a security door, for example. The operation in that case is as follows. When the power is turned on, the inverter 3 is activated to supply a high frequency current to the organic EL sheet 11, thereby causing the organic EL sheet 11 to emit light. Thus, it is possible to notify the user carrying the mobile terminal by emitting light of the organic EL which position or position is touched to perform the ID check by electric field communication. Therefore, a user 21 carrying a portable terminal 20 with a regular ID set can perform ID authentication by electric field communication by standing or touching the place, unlocking the security door, and entering the room.
