Conductive Ink Touch Screen Infrared Controlle Rdesign And Implementation

Along with the increase of the household equipment,the quantity of infrared remote control is improved a lot. People are puzzled by a variety of remote control.More and more shortings are found on the infrared remote control,for example,the human computer interaction is poor,silicon keys easy to aging and most of controllers can control one device.The infrared controller based on conductive ink touchscreen overcome these shortcomings.The controller can control a variety of devices,and easy to operate. Capacitive touch screen is a new type of human-computer interaction, and in keeping with the people’s demands for comfort.Infrared controller based touch screen that is an interactive mode is designed in this paper. Firstly, functions of the controller are introduced,and futher design requirements are proposed. Design requirements include hardware platforms and system software in two parts. The embedded chip HAV1007 is the main chip of controller hardware platform,and it can control data acquisition, judgment action and infrared signal transmitter.The system software includes software framework, the main program design,control logic and algorithms. The part of control logic and algorithms includes digital identification,the operation based on infrared key and the finger operation state machine.A test result shows that the controller can control a variety of equipments and has three modes includes mouse mode, slide mode and digital mode.
