RFID method for guiding visually handicapped
First Claim
1. An RFID method for guiding a visually handicapped person, capable of assisting the movement of the visually handicapped person by the use of RFID tags embedded in guiding bricks, the method comprising steps of:
- defining a plurality types of identification code, each being distinct from one another and to be stored respectively in different RFID tag;
defining a plurality of directions of guidance, each being corresponding to a combination of a specific amount of the identification codes;
forming a preceding record by recording a previous interrogation of RFID tags, being respectively embedded in a guiding brick;
interrogating RFID tags respectively embedded in a guiding brick for forming a current data thereby; and
combining the current data with the preceding record so as to form a direction of guidance to be selected out of the plural previously defined directions of guidance accordingly.

Abstract
The present invention relates to a method for guiding visually handicapped by the use of radio frequency identification (RFID) technology, which is able to issue an audio signal to assist and guide the movement of a visually handicapped person as an direction is being interrogated and obtained from guiding bricks embedded with RFID tags of various identification codes. The method comprises the step of: defining a plurality of identification codes, each being distinct from one another and to be stored respectively in different RFID tag; defining a plurality of directions of guidance, each being corresponding to a combination of a specific amount of the defined identification codes; forming a preceding record by recording a previous interrogation of RFID tags; interrogating RFID tags embedded in guiding bricks for forming a current data thereby; combining the current data with the preceding record so as to select a direction out of the plural previously defined directions accordingly.

wherein, each type of identification code is used to specify a motion to be taken by the visually handicapped person, whereas the motion can be a motion selected from the group consisting of turn, move forward, left turn ahead, right turn ahead, stop, crossroad, stair ahead, and stair-climbing start, and so on; and
the direction of guidance formed with respect to the combination of various identification codes is a direction of guidance selected from the group consisting of going straight forward, turning left, turning right, alerting to stop going forward, alerting to cross-road ahead and climbing stair, and so on.
