The Vellum Advantage
The core technology in Vellum is based on surface infrared (IR) to deliver highly accurate touch detection. Going beyond surface IR, Vellum delivers enhanced functionality and performance – writing while resting your palm on the screen or erasing with the back of the pen – for an authentic, fluid, and nearly flawless writing experience. Unlike traditional IR or other third-party touch technologies that are limited to the glass and touch components, Promethean delivers an end-to-end experience, making writing on the panel truly seamless.
Because Vellum is developed by Promethean, it does not rely on any single vendor for performance enhancements and we can continuously improve on the writing experience as new technologies become available.
