Abstract

A wireless device is possessed by a user. A reporting unit reports, to a management device, status information regarding the surrounding environment of the wireless device and position information of the wireless device. A requesting unit requests the management device to perform guidance to an evacuation route. An accepting unit accepts an instruction for guidance to an evacuation route from the management device when the requesting unit does not request guidance. A notification unit performs notification of an evacuation route.

First claim

What is claimed is:

1 . A wireless device possessed by a user, the wireless device comprising:
a reporting unit that reports, to a management device, status information regarding the surrounding environment of the wireless device and position information of the wireless device; a requesting unit that requests the management device to perform guidance to an evacuation route; and an accepting unit that accepts an instruction for guidance to an evacuation route from the management device when the requesting unit does not request guidance.

2 . The wireless device of claim 1 , further comprising an input unit that receives status information manually input by a user or automatically input by means of a sensor.

3 . The wireless device of claim 1 , further comprising a notification unit that performs notification of an evacuation route when the accepting unit accepts an instruction.

4 . The wireless device of claim 2 , further comprising a notification unit that performs notification of an evacuation route when the accepting unit accepts an instruction.

5 . The wireless device of claim 1 , further comprising:
a receiving unit that receives a signal from the preceding wireless device indicated by information regarding a plurality of wireless devices sequentially arranged along an evacuation route, the information being included in the instruction accepted by the accepting unit; a notification unit that performs notification of an evacuation route; and a transmitting unit that transmits a signal to the next wireless device indicated by the information regarding the plurality of wireless devices, wherein: when the receiving unit receives a signal, the receiving unit allows the notification unit to perform notification; and the transmitting unit transmits a signal upon notification by the notification unit.

6 . The wireless device of claim 2 , further comprising:
a receiving unit that receives a signal from the preceding wireless device indicated by information regarding a plurality of wireless devices sequentially arranged along an evacuation route, the information being included in the instruction accepted by the accepting unit; a notification unit that performs notification of an evacuation route; and a transmitting unit that transmits a signal to the next wireless device indicated by the information regarding the plurality of wireless devices, wherein: when the receiving unit receives a signal, the receiving unit allows the notification unit to perform notification; and the transmitting unit transmits a signal upon notification by the notification unit.

7 . The wireless device of claim 3 , wherein the notification unit changes at least one of output sound, color of emitted light, and order of reporting, in accordance with the distance from the destination of an evacuation route.

8 . The wireless device of claim 4 , wherein the notification unit changes at least one of output sound, color of emitted light, and order of reporting, in accordance with the distance from the destination of an evacuation route.

9 . The wireless device of claim 5 , wherein the notification unit changes at least one of output sound, color of emitted light, and order of reporting, in accordance with the distance from the destination of an evacuation route.

10 . The wireless device of claim 6 , wherein the notification unit changes at least one of output sound, color of emitted light, and order of reporting, in accordance with the distance from the destination of an evacuation route.

11 . A management device, comprising:
a first accepting unit that accepts, from each of a plurality of wireless devices, status information regarding the surrounding environment of the wireless device and position information of the wireless device; a second accepting unit that accepts a request for guidance to an evacuation route from at least one of the plurality of wireless devices; a deriving unit that derives, when the second accepting unit accepts a request, an evacuation route on the basis of status information and position information accepted by the first accepting unit; and an instruction unit that instructs a wireless device arranged along an evacuation route derived by the deriving unit to perform guidance to the evacuation route.

12 . The management device of claim 11 , wherein the deriving unit comprises:
a generating unit that generates a plurality of evacuation route candidates on the basis of position information; and a selecting unit that selects, as an evacuation route, one of a plurality of evacuation route candidates generated by the generating unit, in consideration of status information for each of the plurality of evacuation route candidates.

13 . A guide system, comprising:
a plurality of wireless devices; and a management device capable of communicating with each of the plurality of wireless devices, wherein the management device includes: a first accepting unit that accepts, from each of the plurality of wireless devices, status information regarding the surrounding environment of the wireless device and position information of the wireless device; a second accepting unit that accepts a request for guidance to an evacuation route from at least one of the plurality of wireless devices; a deriving unit that derives, when the second accepting unit accepts a request, an evacuation route on the basis of status information and position information accepted by the first accepting unit; and an instruction unit that instructs a wireless device arranged along an evacuation route derived by the deriving unit to perform guidance to the evacuation route.

14 . A non-transitory computer-readable memory medium storing a computer program comprising:
accepting, from each of a plurality of wireless devices, status information regarding the surrounding environment of the wireless device and position information of the wireless device; accepting a request for guidance to an evacuation route from at least one of the plurality of wireless devices; deriving, when a request is accepted, an evacuation route on the basis of accepted status information and position information; and instructing a wireless device arranged along a derived evacuation route to perform guidance to the evacuation route.
