Whiteboard Technology Overview
The growth in Interactive Whiteboards (IWB) is testament to the adoption of new interactive and computer based techniques throughout the world. IWBs are primarily used in a variety of settings such as educational classrooms, corporate boardrooms and workgroups, training rooms for professional sports coaching, TV studios and more.
Baanto™ ShadowSense™ technology is capable of adding interactivity to most any flat surface. Whether it be a retrofit to a traditional chalkboard or dry erase market board, or a new system incorporating a TFT or projector for displaying computer images, a ShadowSense(R) system adds interactivity with both active pens, passive touch, or a combination of both input methods. Multi-user, multi-touch, and multi-object detection make these systems flexible and adaptable to most any user requirements.
Features
The active pen designs use a common, low cost sensor design which is suitable for all white board sizes up to 240” diagonals. This sensor architecture is capable of resolving and tracking up to 4 pens simultaneously without increasing the need for computational resources or reducing the system performance of the host PC.
Cross-over, co-linearity and occlusion issues are non-existent due to the use of unique IDs for each pen and frame rates of up to 240 FPS per pen are achievable.
A resolution of 1mm provides outstanding clarity to text and sketches and since pen position measurements are tracked and displayed within milliseconds of capture, the system has a responsive and crisp feel. Automatic and continuous background calibration eliminates temperature and frame distortion issues, simplifying initial installations and allowing the system to be moved as required.
