In this paper, we present a novel human-computer interaction method based on the true three-dimension display, design a true three-dimension display multi-touch system based on Perspecta 3D display system, and realize the software algorithm. Vision-based Frustrated Total Internal Reflection (FTIR) multi-touch technique is used to get the positions where the users touch the domed acrylic of the true...
In this paper, a multi-touch analyzing algorithm is presented to meet the requirements of the educational application. The proposed algorithm is designed for the purpose of multi-camera, high efficiency and low CPU consumption, which includes background image accumulation, blob recognition, blob tracking, multi-camera collaborative process, data fusion and blob track post processing algorithm etc...
