摘要

The paper presents the illumination engineering for a low-cost multi-touch projection screen. Eight near infrared emitting diode (IRED) strips with optimized line densities serve as the illumination sources for the finger tracking. The design achieves highly uniformed illumination, with an illumination efficiency of 55% and contrast of 0.098. Implementation and experimental results are presented.
