AGENDA What is Pointing Device? Virtual Point System System Architecture Detection and Recognition Coordinate Mapping Mouse Interaction Future works

What is Pointing Device? Message

Virtual Point System Ubiquitous concept Using USB Camera Escape from the limit of location by Image Processing

System Architecture Hardware part 2 USB Camera Capture frame Beam Projector Software part Image Processing Module Coordinate mapping Module Mouse Interaction Module

Image Processing 30 frame per sec Fix camera at 45 degree angle Needed Frame that limit user motion

Image Processing Save the first frame image Get real time image data Set change gray scale image Compare first image and real time image Get Difference of image Get Hand’s position

Detection and Recognition User movement capture module

Detection and Recognition Motion detection

Coordinate Mapping

P ( x, y ) ! Q ( u ; v )

( 1 ) ( 2 ) ( 3 ) ( 4 ) ( 5 ) ( 6 )

Detection and Recognition A method of point detection

Mouse Interaction Mouse move event Mouse Left button click event

Future works Improve the system to more approach the Ubiquitous system. Free camera angle Remove the Capture frame

Thank you!! Have a good time in Malaysia.
