Abstract:
A wireless communication keyboard includes a key module and a wireless communication module. The key module has a plurality of keys each can be depressed by a user to output a keyboard command. The key module also has a press combination including at least two keys which are depressed by the user at the same time to output a target search command. The wireless communication module is connected to the key module to receive the keyboard command and target search command, and has a linkage target setting state to search a linkable information device within a linkage range upon receiving the target search command. Thus user can quickly search the linkable information device through the press combination.
Abstract:
A method for controlling light emission of a light sensing keyboard is to save in advance a driving correlation table including a plurality of driving codes in the light sensing keyboard. Each driving code corresponds to a trigger signal and is triggered by the trigger signal to generate a driving signal which defines a light emission mode. When a light detection unit detects ambient light parameters, the trigger signal is generated and the driving code corresponding to the trigger signal is read from the driving correlation table. A control unit generates the driving signal according to the driving code to drive light emission elements to emit light and also control each light emission element to execute the light emission mode corresponding to the driving signal, thereby synchronous or asynchronous colored light alteration can be generated to provide flickering or alternate light alteration effect.
