PocketTouch是一款电容式感应原型，它可以在手持设备上实现裸眼多点触摸输入，而无需将设备从裤子、衬衫、包或钱包的口袋中取出。PocketTouch支持丰富的手势交互，从简单的触摸到完整的字母数字文本输入。我们的原型设备由安装在智能手机背面的自定义多点触摸电容传感器组成。通过对电容式传感器的低级别访问，可以在大多数现有的电容式触摸屏上启用类似的功能。我们演示了如何触摸笔画可以用来初始化交互设备，以及如何处理笔画，使文字识别的字符写在同一个物理区域。我们还提供了一个比较研究，经验性地衡量不同的织物如何衰减触摸输入，为未来的调查提供了见解。我们的研究结果表明，PocketTouch将与当今服装中使用的各种织物可靠地工作，并且是一种可行的输入方法，用于口袋中设备的快速无眼操作。
PocketTouch is a capacitive sensing prototype that enables eyes-free multitouch input on a handheld device without having to remove the device from the pocket of one's pants, shirt, bag, or purse. PocketTouch enables a rich set of gesture interactions, ranging from simple touch strokes to full alphanumeric text entry. Our prototype device consists of a custom multitouch capacitive sensor mounted on the back of a smartphone. Similar capabilities could be enabled on most existing capacitive touchscreens through low-level access to the capacitive sensor. We demonstrate how touch strokes can be used to initialize the device for interaction and how strokes can be processed to enable text recognition of characters written over the same physical area. We also contribute a comparative study that empirically measures how different fabrics attenuate touch inputs, providing insight for future investigations. Our results suggest that PocketTouch will work reliably with a wide variety of fabrics used in today's garments, and is a viable input method for quick eyes-free operation of devices in pockets.
