<P>PROBLEM TO BE SOLVED: To provide a force sensor type light-emitting keyboard comprising at least one key, a pressure detection circuit, a light-emitting module, and a control unit. <P>SOLUTION: In a force sensor type light-emitting keyboard, a pressure detection circuit detects a first pressure and generates force sense strength voltage when a user presses on the keyboard with the first pressure. At the same time, a control unit determines the strength of the first pressure based on the force sense strength voltage and controls a light-emitting module to generate a first beam or a second beam based on the strength of the first pressure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
