Why Recognise Gestures?
New Models of Interaction
Parameters of Recognition
How Does it Work? • Find the Hand (not my problem!) • Find Interesting Regions on Hand • Track Interesting Points • Compare Hand Path / Relative Position
Interesting Points • Edge Detection • Corner Detection • Regions of High Gradient of Change • Brightness / Colour Histogram
Tracking Points • Iterative Lucas - Kanade Method • Pyramid Feature • Outputs New Points and Probabilities
Tracking the Hand • ‘Flock’ of points • Cull outliers • Median (x and y) of Points is Centre of Hand
Recognising Gestures • Relative Position of Hands from ‘Start’ • Trace Path of Hand Centre
Applications • TV Control • Ubiquitous Systems Control • Games (Johnny Lee Eat Your Heart Out)!
