摘要
电脑触摸屏技术通过USB芯片被电脑识别为鼠标,对碰触信号进行位置检测、模数转换和运算来对电脑鼠标指针进行定位,通过触笔上的按键和滚轮替代电脑鼠标的按键和滚轮。USB芯片的HID功能使设备免除了驱动程序,碰触定位操作与按键、滚轮操作的分离进行,全面替代了鼠标的操控功能。此技术具有带按键触笔和免驱动特性两大创新点,在人机交互设备技术领域具有明显的新颖性、创造性和实用性,有广阔的应用前景。
In order to simulate and actualize PC mouse and to fill the blanks of technology and market,the article introduces a PC touch screen technology.The device is regarded as PC mouse via a USB chip.It senses touching positions,performs A-D conversion and calculation to set mouse pointer destination.The buttons and wheel on the touch stylus serves as mouse buttons and wheel.No device driver is needed because of HID function of the USB chip.It totally substitutes PC mouse because of the separation of touching positioning and button functions.With the two innovations： touch stylus with buttons and driver-free feature,this technology is novel,innovative,practical and promising in the field of human-computer interaction.
