Abstract

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. The proposed algorithm is tested on different multi-touch platforms such as FTIR, DI and LLP with typical multi-touch educational software. Experimental result shows that the proposed algorithm adapts to the requirements of educational application.
