The user writes with the VPen™ on any surface. The relative motion is captured
by the OTM™ sensor located at the tip of the VPen™, decoded into ASCII
characters using a character recognition software (ICR) and streamed to the
handset screen. In a similar way, the user can draw a picture or move the
cursor on the handset screen.
Here is an inside view of the VPen™ and how it works:
- VPen™ core – captures 3D motion. The VPen™ core includes an OTM™ sensor, ASIC, stylus tip, pressure sensor and mode button.
- In-line character recognition (ICR) software on a chip– translates handwriting into ASCII characters. The handwriting recognition software can be embedded either in the pen or the target device or in both.
- Data transmission link – transmit streaming ASCII characters and mouse events to the target device, in real time using Bluetooth. Other transmission links are possible, such as wire, USB, IrDA or embedded links.
- Battery pack – provides power using rechargeable batteries.
- Ergonomic design – ensures optimal grip, comfort, and convenient use.
