Smart 3D pointing device based on MEMS sensor and bluetooth low energy

The paper deals with the development of a new type of wireless pointing device based on 3D MEMS sensor as measuring component. Currently available pointing devices based on MEMS sensors (AIR mouse or AIR presenter) use proprietary wireless solution and their dimensions are copied from standard mouse. The new approach of our pointing device is based on standardized Bluetooth Low Energy protocol with minimal dimension and 3D way of control. This device can be used like a standard mouse in 2D with computer equipped by Bluetooth 4. The third measured dimension can be used to switch X or Y axis to Z plane, because we can control pointer without flat surface. The change of 2D pointing plane from XY to YZ or XZ can be switched intelligent by detection of acceleration activity in third axis. The device in full 3D mode will be used for control of rehabilitation arm in teaching mode by patient or therapist.
