52in红外液晶显示模块图像传感器集成了多重触摸功能,可以探测普通基板周围的触摸。方法是通过放置一些红外图像传感器来探测触摸。触摸算法中用到三角剖分、图像处理技术以及模式识别。同时通过红外图像传感器、红外光源和LCD基板计算出触摸点位置。另外,触摸数量和触摸面积用于实现多重触摸功能。多重触摸LCD也可以探测人的手势。在这里,地图寻找程序使用了触摸和手势识别。结果是多重触摸LCD显示出它的有效性,可以用来替代传统的人机界面设备(如鼠标、键盘)。
52in Infrared LCD Module The image sensor incorporates a multi-touch function that detects touches around common substrates. The method is to touch by placing some infrared image sensor. Triangulation, image processing techniques and pattern recognition are used in touch algorithms. At the same time through the infrared image sensor, infrared light source and LCD substrate to calculate the touch point position. In addition, the number of touches and the touch area are used to realize the multi-touch function. Multi-touch LCD can also detect human gestures. Here, the map finder uses touch and gesture recognition. The result is a multi-touch LCD that shows its effectiveness as an alternative to traditional human-machine interface devices such as mice and keyboards.
