Alignment Errors between Real and Virtual World in Augmented Reality

Fribourg (Switzerland), October 2005


In the last decade, augmented reality (AR) technology was of significant interest in the medical field. However, designing a medical AR system is still challenging, because the expectations on accuracy and stability in such a setting are high. Misalignment of the computer-generated objects would greatly compromise the utility of such systems. Especially in medical training, where the viewpoint of the trainee can largely vary, such inaccuracies can deteriorate manipulative skill training and the sense of presence and thus reduce the training effect. Our project is to develop a medical training simulator for othopaedic surgery by using AR techniques. The presented study deals with the different error sources encountered in developing such a system.
