发明名称 CALIBRATION METHOD AND INFORMATION INPUT HELP SHEET USED FOR THE SAME METHOD
摘要 The technical objective is to provide a simple and low-cost information input help sheet and an information processing system which exhibit a significantly high input accuracy and input efficiency without limiting a mounting object. The information input help sheet comprises an infrared reflection layer which reflects infrared rays from one side and transmits visible light, and a dot pattern layer provided on one side of the infrared reflection layer and on which dots generated by a dot-code generating algorithm and formed with material having an infrared absorbing characteristic are arranged according to a predetermined rule, in order to perform a variety of multimedia information output and/or operation instructions.
