are public places where a large number of people in a rather limited space
share common facilities. Patients, clinical staff and visitors can all become
potential carriers of biological hazards simply by touching a door handle or
pressing a button in the elevator.
this project we intend to develop and demonstrate a non-contact switch for electrical devices. The switching device generates a holography of a press-bottom. As the users finger intersects the virtual image the switching device
can produce a suitable trigger signal from light
backscattered by the finger.
