The new generation of portable computers, especially Tablet PC’s and pen enabled notebook computers require a rethinking of natural input strategy and the accompanying technology. Existing technology has enabled partial, piecemeal solutions limiting users to either pen or touch, or hindering their work with suboptimal speed and sensitivity.

The Electrostatic pen solution

The DuoSense electrostatic pen provides high quality active pen support, without requiring batteries, and as such is ideal for the enterprise market. Using a conductive capacitor that is inbuilt as part of the pen, it connects to an electromagnetic field generated by an excitation coil in the digitizer. The frequencies of the conducted electromagnetic waves are controlled by the computer system, which enables a smooth handwriting experience.

DuoSense^® dual-mode digitizer supports both pen and touch, leveraging a uniquely accurate capacitive sensing system mounted in front of the LCD panel.
