MultiTouch has announced a new technology it calls Hybrid Tracking that the company says completely eliminates the interference from external ambient light.
Instead of blocking infrared light emitted by external sources, the system makes use of it. This is achieved by tracking the shadows or the external infrared light and combining that information with the reflections that the IR sensors see through the LCD.
Hybrid tracking doesn’t require any hardware changes to your existing system, and is available as a free software upgrade to all MultiTaction displays.
