Abstract

In this paper we describe extensions to our work on ThinSight, necessary to scale the system to larger tabletop displays. The technique integrates optical sensors into existing off-the-shelf LCDs with minimal impact on the physical form of the display. This allows thin form-factor sensing that goes beyond the capabilities of existing multi-touch techniques, such as capacitive or resistive approaches. Specifically, the technique not only senses multiple fingertips, but outlines of whole hands and other passive tangible objects placed on the surface. It can also support sensing and communication with devices that carry embedded computation such as a mobile phone or an active stylus. We explore some of these possibilities in this paper. Scaling up the implementation to a tabletop has been non-trivial, and has resulted in modifications to the LCD architecture beyond our earlier work. We also discuss these in this paper, to allow others to make practical use of ThinSight.

建立一个薄的形式因素触摸和有形桌面的经验
在本文中,我们描述了对ThinSight工作的扩展,这是将系统扩展到更大的桌面显示所必需的。该技术将光学传感器集成到现有的现成lcd中,对显示器的物理形式影响最小。这使得薄的形状因素传感超越了现有的多点触摸技术,如电容或电阻方法的能力。具体来说,这项技术不仅可以感知多个指尖,还可以感知整个手的轮廓和其他放置在表面上的被动有形物体。它还可以支持与携带嵌入式计算的设备(如移动电话或有源手写笔)的传感和通信。我们在本文中探讨了其中的一些可能性。将实现扩展到桌面是非常重要的,并且导致对LCD架构的修改超出了我们早期的工作。我们还在本文中讨论了这些问题,以便其他人能够实际使用ThinSight。
