摘要 |
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.
