Low-complexity MARG algorithms for increased accuracy in space pointing devices

摘要

This paper addresses the accuracy of space pointing devices when using absolute orientation for interaction with multimedia content. Classical accurate fusion algorithms are computationally intensive, therefore their implementation in low-energy consumption devices is a challenging task. To tackle this problem, a performance study of a relevant set of COTS MARG sensor units with low-complexity algorithms, is presented in this study. Performance evaluation tests are carried out under harsh conditions to observe the algorithms response in a non-trivial environment. The results demonstrate that the implementation of low-complexity algorithms using low-cost sensors, can provide acceptable accuracy in comparison with the more complex state-of-the-art sensors/algorithms. These results pave the way for faster adoption of absolute orientation-based pointing devices in interactive multimedia applications.
