本文介绍了一些将日常生活物体转化为触觉界面的技术，并以光球、托盘和桌子为例介绍了实现细节。这些技术可以分为两大类，声学技术和计算机视觉技术。声学技术利用触摸物体时产生的振动，这些振动通过物体表面传播，直到到达附着在物体表面的压电传感器。计算机视觉方法是用于虚拟键盘的技术的扩展，其基础是检测手指拦截由一对激光模块投射在表面上的红外光平面。它允许在任何平面上进行多点触摸感应。
This article describes a few techniques to transform daily life objects into tactile interfaces, and presents the implementation details for three objects chosen as example: a light globe, a tray and a table. Those techniques can be divided in two main categories, acoustic techniques and computer vision techniques. Acoustic techniques use the vibrations that are produced when touching an object and that are propagating through and on the surface of the object until reaching piezo sensors attached on the surface. The computer vision approach is an extension of the technique used for virtual keyboards, and is based on the detection of fingers intercepting a plane of infrared light projected above the surface by a pair of laser modules. It allows for multi-touch sensing on any flat surfaces.
