11. Physical Environment: other alternative solutions VS proposed solution

14. Framework Calibration Segmentation Hand Detection Multi hand Tracking Touch Detection Gesture Recognition Event Interface

15. apply a geometric calibration using the four calibration points acquired by the configuration module. Calibration Segmentation Hand Detection Multi hand Tracking Touch Detection Gesture Recognition Event Interface

16. Experimental Results Simple back ground Complex back ground It’s main task is to generate a binary image from the captured image represents the foreground Calibration Segmentation Hand Detection Multi hand Tracking Touch Detection Gesture Recognition Event Interface

17. Experimental Results responsible for detecting the hand position automatically at any position, with certain gesture (Open Hand) Calibration Segmentation Hand Detection Multi hand Tracking Touch Detection Gesture Recognition Event Interface

18. Experimental Results responsible for keep track with the user hand, know the actual position of the hand all the time Calibration Segmentation Hand Detection Multi hand Tracking Touch Detection Gesture Recognition Event Interface

19. Experimental Results the main task is to decide whether the user did touch the screen or not Calibration Segmentation Hand Detection Multi hand Tracking Touch Detection Gesture Recognition Event Interface
