Abstract :
The performance of Augmented Reality (AR) direct object selection coded outside of the human egocentric body frame of reference is decreased under short-term altered gravity. Therefore an adequate countermeasure is required. This paper presents the results of a proof-of-concept (POC) study to investigate the impact of simulated hypergravity on target´s size and distance. For gravity-dependent resizing and -positioning we used Hooke´s law for the target deformation. The POC study was divided in two experiments, whereby hypergravity was induced by a long-arm human centrifuge and by weights attached to subjects´ dominant arm. The study showed that at higher gravity levels larger target size and larger distance between the targets led to increased performance.
