RFID-BASED OBJECT TRACKING FOR THE VISUALLY IMPAIRED

摘要

The invention relates to RFID-based object tracking for the visually impaired. The invention uses a mobile RFID reader which is built into a mobile device having a processing capacity and adapted for the visually impaired, with the aim of locating objects and areas of interest in the home using active and passive UHF RFID tags. Three categories of tagged elements can be distinguished: fixed, semi-static and dynamic. Upon detection of tags close to the antenna, an association (object, location) is made in the database which may be located locally in relation to the device or remotely, so that multiple mobile devices can access same. The invention has three operating modes: normal, in which the database is updated regularly with locations query, in which the name of the object is indicated and the last location in which said object was detected is supplied and search, in which an alarm is activated if the object is detected.
