A virtual keyboard that can be applied to glass is planned to be ready by spring 2005. Two vibration sensors are mounted on the back of the glass to detect precisely which keys are selected. Designed as a standard product, it can be used on any plate glass surface that is up to two square metres in size and 10 mm thick – it can even be engraved into the glass. It is easy to maintain, robust and has no moving parts.
This technology, previously used in Ariane launchers, will provide innovative solutions in many areas including medical because it is hygienic; in wet locations because glass is impervious to water and in public areas as the system is well protected against vandalism.
