Abstract
This research work discusses about the tracking system and also recognizing gestures using Tracking-Learning-Detection (TLD) for camera based multi-touch technology. The tracked fingers are assigned unique IDs, and the information about the finger movements are passed to the TUIO protocol. This enables us to have a communication channel between the screen elements and the touch input. A novel and low-cost approach for tracking objects is discussed. This proposed works facilitate to remove the noise by image processing technique. In this research concluded that, the issue of the touch input technologies is large and the implementation has been fulfilled, and also relatively cheap device was built successfully.
