METHOD FOR PROVIDING AUDIO INFORMATION TO A VISUALLY IMPAIRED PERSON OR BLIND PERSON USING RADIO-FREQUENCY ELECTRONIC DEVICES AND RELATED SYSTEM

摘要

The present invention relates to a method (300) for providing audio information to a partially sighted/blind person using radio frequency electronic devices of an electronic system (1000). The system comprises:- one or more identification devices (10) fastened to items of an environment, wherein each identification device comprises a radio frequency electronic device (2);- a first portable electronic apparatus (20) configured to query the radio frequency electronic device of the identification devices;- a second portable electronic apparatus (30) configured to communicate in a wireless mode with the first portable electronic apparatus.The method comprises the following steps performed by the first portable electronic apparatus:- detecting (301) a first unique identifier (ID1) of the radio frequency electronic device representative of an item accommodated in the environment;- sending (302) to the partially sighted or blind person a notification signal of the successful detection of the radio frequency electronic device;- generating (303) a first message (m1) including the first unique identifier and a second unique identifier (ID2) representative of the first portable electronic apparatus;- transmitting (304) by radio broadcasting a first signal (S1) including the first message.Furthermore, the method comprises the following steps performed by the second portable electronic apparatus:- receiving (305) the first message (m1) transmitted with the first signal (S1);- processing (306) the first message (m1) received to extract said first unique identifier (ID1) and second unique identifier (ID2);- selecting (307) a first audio information representative of the item accommodated in the environment, starting from the first unique identifier (ID1) extracted, such first audio information being stored in a memory unit operatively associated with the second portable electronic apparatus (30).In case the selecting step has a positive outcome, the first audio information is made available (308) to the partially sighted or blind person by means of the second portable electronic apparatus (30).
