Abstract:
Most human-computer interaction systems, specifically, Augmented Reality, are designed based on general purpose processors. Consequently, their power consumption is considerably high, as systems work at Gigahertz rates. In this paper, power efficient interactive augmented reality learning applications for children are designed and implemented. Interaction is performed by hand gestures and markers. The power consumption of the proposed system is reduced by developing and implementing the recognition and tracking processes on a Field Programmable Gate Array platform to exploit its parallelism feature. This enables the system to work, portably, at lower operating frequencies, without violating the required real-time performance. The most suitable five hand gestures for 3 to 10-year-olds were determined, then the implemented system was tested by 100 children. Implementation results revealed that only 25 MHz are sufficient for the applications to run in real-time at 30 fps, with a recognition rate of 93.2% on average. This significantly reduces the overall power consumption of the proposed system, comparing with other systems.
