Hand Tracking For Low Powered Mobile AR User Interfaces

Mobile augmented reality systems use general purpose computing hardware to perform tasks such as rendering computer graphics, providing video overlay, and performing vision tracking. Our current Tinmith-Metro modelling system implements a user interface which is based on tracking the motions of gloves worn by the user, but is implemented inefficiently in a mobile laptop carried on a backpack by the user. This paper describes how we have developed a tracking algorithm which is suitable for implementation in a field programmable gate array. This implementation uses minimal power and will allow future miniaturisation of our mobile backpack equipment. We present the results of studies conducted outdoors to find the most appropriate marker type to use, and also the overall results that were achieved during testing.
