This project will develop pre-touch sensing for capacitive touchscreens to the point where it is useful for automotive and industrial applications to help improve their safe use and to open up new and innovative ways to interact with a touchscreen.Using a capacitive touchscreen in a vehicle can be challenging while the vehicle is in motion as accurate finger positioning is difficult, leading to driver distraction. Zooming the display before the user touches or predictively popping up secondary menus can significantly help usability if the sensing distance is far enough away. Some vehicles already have rudimentary versions of the technology enabled using IR sensor arrays but this is expensive, hard to implement and limits industrial design options.The potential to use the electric fields from a capacitive touchscreen to detect an approaching hand or finger has been known for several years but due to performance limitations (the need to measure changes in capacitance on the order of atto-farads) the technology has never been successfully deployed.Based on a new measurement IC which uses novel technology concepts, TouchNetix will research the system aspects of pre-touch by exploring the complex interactions between IC, sensor, display and other system hardware to extend and maximise the distance at which a finger can be detected in front of the screen.A complete demonstration system will be developed which it is hoped will routinely detect an approaching hand from 10-20cm away and which gives accurate finger positions 5-10cm away from the touchscreen.Automotive, industrial and medical markets will benefit from the technology, allowing safer and novel HMI systems and applications to be developed.

该项目将开发电容式触摸屏的预触摸感应技术，使其在汽车和工业应用中发挥作用，帮助提高安全使用，并开辟与触摸屏交互的创新方式。在车辆行驶中使用电容式触摸屏可能具有挑战性，因为很难准确定位手指，导致驾驶员分心。如果感应距离足够远，则在用户触摸之前缩放显示或预测性地弹出二级菜单可以显著地帮助可用性。一些车辆已经使用IR传感器阵列实现了该技术的初级版本，但这是昂贵的，使用来自电容式触摸屏的电场来检测接近的手或手指的可能性已经已知了几年，但是由于性能限制，（需要测量阿托-法拉量级的电容变化）该技术从未被成功部署。基于使用新颖技术概念的新测量IC，TouchNetix将通过探索IC，传感器，显示器和其他系统硬件，以扩大和最大限度地提高在屏幕前可以检测到手指的距离。该技术可在距离触摸屏5- 10厘米的范围内提供准确的手指位置。汽车、工业和医疗市场将受益于该技术，从而开发出更安全、更新颖的HMI系统和应用。
