A mobile Passive Augmented Reality Device - mPARD

Describes an RF-based approach to mobile augmented reality (AR), solving the problem of providing sufficient computational and graphics power on conventional wearable computers. Two devices are presented which work together and can be used either in a hand-held AR display version or as a wearable version using an external mobile camera and a head-mounted display. The process of evaluation and improvement is ongoing, but the results so far are presented, including usability tests in industrial applications.
