Description

A talk about my undergraduate individual project which I gave at BarCampNorthEast 2007, several months before completing my project. It gives an overview of a hand gesture recognition system, detailing how interesting points on a hand are found and tracked.

Why Recognise Gestures?

New Models of Interaction

Accessibility!

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)!

Demo!
