[edit] Native Dual Mode

Empowering Creativity

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.

[edit] Electrostatic pen solutions

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.

[edit] Battery operated pen

Can be used as an addon for a touchscreen surface not originally designed for an electrostatic pen (no excitation coil). Requires less power from the device. AAAA Battery lasts up to 18 months.

[edit] Capacitive touch

DuoSense® dual-mode digitizer supports both pen and touch with up to 4 finger multi-touch support.
