What is Vellum Touch Technology?
Vellum technology was designed by the renowned brand Promethean, recognizing the importance of writing during classroom sessions. Vellum was developed to closely mimic the traditional writing experience, helping students and teachers feel comfortable while interacting with the screen.
How Vellum Touch Works:
The core technology behind Vellum is based on surface infrared (IR), specifically enhanced by Promethean for highly accurate touch detection. Vellum goes beyond the concept of traditional surface infrared, offering improved functionalities and performance, such as writing with the palm on the screen or erasing using the back of a stylus, unlike conventional touch technologies that are limited to glass and touch components. Promethean provides a comprehensive experience that makes writing on the interactive screen smooth and incredibly realistic.
Inside the Mechanism of Vellum Touch:
1. Specially Treated Glass: 
The technology utilizes specially treated glass, giving it a smooth and comfortable feel, with enhanced anti-glare properties for an optimal viewing experience in various classroom lighting conditions.
2. Enhanced Sensors and Algorithms:
The improved touch sensors and robust algorithms accurately detect objects touching the screen, such as a stylus or finger, while infrared signals precisely determine the size and position of these objects. Additionally, Vellum technology integrates seamlessly with applications like the Whiteboard developed by Promethean. Promethean's stylus and eraser were specifically designed based on teachers' feedback to work effectively and smoothly with Vellum technology.
With Promethean's Vellum touch writing technology, you will enjoy a modern and realistic writing experience without limits, enabling teachers and students to write smoothly, accurately, and economic cost.
