Abstract:
An aid system for the visually impaired or blind includes a first tag positionable on an object and having a first receiver/transmitter that receives an interrogation and transmits a data signal containing an identification code, a user interface device for a user associated to a second tag having a second receiver/transmitter that transmits a data signal containing an identification code of the user interface device and receives a data signal; a local receiver detecting a location of the first and second tags, and a control unit communicating with the local receiver and storing data, wherein the data signals contain: from the tag to the receiver, the identification code; from the receiver to the control unit, the identification code and the location of the first and second tags; and from the control unit to the user interface device, the location and identification code of the first tag.
Abstract:
The present invention relates to an aid system (1) for visually impaired or blind people comprising - a first tag (2, 20) positionable on an object provided with at least one first receiver/ transmitter (21) intended to receive at least one interrogation and to transmit at least one data signal containing at least one identification code of said first tag, - a user interface device (5) which is: provided with at least interface means (51) for users suffering from visual disabilities and associated to a second tag (6) provided with at least one second receiver/ transmitter (61) intended to transmit a data signal containing at least one identification code of the user interface device and to receive a data signal; the system further comprises a local receiver (3) intended to detect at least one three-dimensional space location of said first tag (2,20) and second tag (6), and a control unit (4) provided with receiving/ transmitting means intended to be put in communication with said local receiver (3) and provided with at least storage means for storing the data, wherein at least a part of the data signal transmitted: from the tag (2, 20, 6) to the receiver (3) contains at least said identification code, from the local receiver (3) to said control unit (4) contains at least said identification code and data about a three- dimensional space location of said tag (2, 20, 6), from the control unit (4) to the user interface device (5) contains data about the three-dimensional space location of said first tag (2, 20), and data about the identification code of said tag (2, 20); the invention further relates to a method for the operation of said system.
