Sixth Sense Teaching Aid

Abstract

This paper proposes a novel Sixth Sense Teaching Aid (SSTA) which incorporates sixth sense technology in projectors for educational purpose. The Projector-PC system was earlier used only for displaying the presentations but with the aid of the proposed system, users can touch on any projected surfaces for interaction purpose. In the SSTA system, the graphical user interface (GUI) buttons are projected on any flat surface like wall and it deals with touch detection of the projected screen using red color parameter both for still image and real time images. The algorithm to perform touch detection is executed in two stages: 1) Feature extraction and button’s touch detection using red color thresholding algorithm which reduces the computational complexity of the processing module; and 2) Performance of assigned operation according to touch action judgment. New born technology named Sixth Sense technology is also implemented in SSTAfor getting relevant information from the internet, whenever we touch any projected Figure or headline. The proposed SSTA system is able to do real time touch detection with 97 percent accuracy which is demonstrated through projected GUI and using a data set collected under different settings of illumination variation, hand orientation and occlusion.
