Abstract
The present invention discloses a single sensor performing both tactile and proximity sensing. The sensor includes a magnetic field generator, a magnetic field sensor for sensing changes in the magnetic field in response to an object changing position with respect to the field to provide proximity sensing. By providing for relative movement between the response to the object touching the sensor, tactile sensing is provided.
