Its variety of sensors and their high accuracy render it superior to many commercially available systems. An improved prototype was presented at the Hanover CeBIT'95. Twelve pressure sensors on the glove's palm measure forces occurring during object grasping. Sensors currently used on the project will be supplemented by new ones which are being developed by the microsensorics research group. During the first phase of the project, the group will concentrate on developing acceleration sensors for the glove.
Accelerometers have a much higher resolution measuring fast movements than ultrasonics.
The glove's path in 3-space can be reconstructed mathematically if simultaneous acceleration measurements are made for all three dimensions. This calls for the development of new micromechanical devices, as up to now, sensors capable of triaxial, on-chip acceleration measurements are not available. It is very important to have a close working relationship between the microsensorics and the computer science research group, as sensor specifications, signal processing issues and sensor characteristics have to be thoroughly discussed. Only this ensures the developed sensors' correct and successful operation on the glove. The semiotics research group will evaluate various gestural codes concerning their suitability for recognition with the SensorGlove.
