A new RFID-based and ontological recreation system for blind people

摘要

More than five million people are blind in China. Computer game should be attractive to them for leisure time, especially Mahjong. Ontology theory has been adopted to retrieve its knowledge and the low-cost RFID as the mediation between the blind player and computer. We designed an autonomous computer platform called Blind Mahjong Game (BMG), which includes 144 Mahjong tiles and voice prompt function. BMG comprises a plurality of Mahjong cubes (stuck RFID tag) their location in the Mahjong-selection tray or Mahjong-discard tray, a plurality of Chow-Pong-Kong-Win indicator cubes, a win frame, a tile frame, at least one RFID reader connected to BMG by USB port gateway to transmit an RF signal. As compared to current static or drab game for the blind, BMG has been certified by two patents in Taiwan which have shown that its software and hardware integrated novelty, progress and utilisation in the application of RFID technology for the blind.
