A wireless pen for mobile keyboard and mouse replacement. Typical target devices are mobile phones, PDA or PC.
 
The pen is based on an OTM (Optical Translation Measurement) sensor for tracking motion. The sensor sends analog signals, which are being translated to digital signals and analyzed by a DSP to find the exact movement in X-axis, Y-axis and Z-axis.  The TI OMAP microprocessor runs hand writing recognition software that recognizes characters and sends the result through a Bluetooth transceiver to the target device.
