System for responsive to detection, acoustically signalling desired nearby devices and services on a wireless network

摘要

The invention relates to a distributed electronic system having at least one device G 1 able to be perceived ( 2 ) and at least one device G 2 capable of perception ( 3 ), which latter has an acoustic output. To enable devices of a type being looked for by a user to be more easily perceived, G 1 ( 2 ) and G 2 ( 3 ) co-operate with one another by automatic intercommunication in such a way that the user learns at any time by means of audible signals which types of device are located in the area surrounding him. In an embodiment, G 2 comprises a perception profile storing desired device-types for comparison in a Bluetooth service discovery process. G 2 can be part of a headphone or hearing aid, and the audio sequences can be edited by an application linked to G 2 via the ad-hoc interface.
