Deformable touch sensitive surface
TLDR
In this article, a touch sensitive device is arranged with substantially parallel surfaces inside which light from a synchronized source, such as a CRT, can become trapped by total internal reflection, and the screen is fitted with photodetectors which respond to the entrapment of light within the surfaces.Abstract:
A touch sensitive device is arranged with substantially parallel surfaces inside which light from a synchronized source, such as a CRT, can become trapped by total internal reflection. The screen is fitted with photodetectors which respond to the entrapment of light within the surfaces. The device is compliant so that a touch of the device at a particular point will cause an inward deflection of the surface at that point. The deflection causes light to become entrapped within the surface by total internal reflection thus making it possible, by comparing the photodetector output with the CRT raster position, to determine the exact surface position of the touch.read more
