Object Selection by Relative Hand to Cursor Mapping : Design and Evaluation of a 2D-Object Selection Technique for Hand Tracking in Virtual Environments

Sammanfattning: Hand and tracker jitter negatively affect performance with ray-casting in virtual environments, making it difficult to acquire small objects which require high levels of precision. This study evaluates an alternative target acquisition technique for 2D-interfaces in virtual environments with relative hand-to-cursor mapping. Trade-offs between the relative hand-to-cursor mapping and ray-casting are explored in comparative evaluation, utilizing Fitts's law, SUS-surveys and interviews. The results demonstrate that relative hand-to-cursor mapping performs equal to ray-casting while also allowing higher precision in certain selection tasks.
