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.

该项目将为电容式触摸屏开发预触摸传感技术，使其可用于汽车和工业应用，以帮助提高其安全使用并开辟与触摸屏交互的创新方式。在车辆中使用电容式触摸屏当车辆行驶时，手指的准确定位很困难，导致驾驶员分心，这可能是一项挑战。如果感应距离足够远，在用户触摸之前缩放显示屏或预测性弹出二级菜单可以显着提高可用性。一些车辆已经具备了使用红外传感器阵列的该技术的基本版本，但这种技术成本昂贵，难以实施，并且限制了工业设计选项。利用电容式触摸屏的电场来检测接近的手或手指的潜力众所周知。几年来，但由于性能限制（需要测量阿托法拉量级的电容变化），该技术从未成功部署。基于采用新颖技术概念的新型测量 IC，TouchNetix 将研究以下系统方面的问题：通过探索 IC、传感器、显示器和其他系统硬件之间的复杂交互来进行预触摸，以延长和最大化屏幕前检测到手指的距离。将开发一个完整的演示系统，希望该系统能够定期进行检测 10-20 厘米外接近的手，并提供距触摸屏 5-10 厘米的准确手指位置。汽车、工业和医疗市场将从该技术中受益，从而可以开发更安全、新颖的 HMI 系统和应用程序。
