Increasing Precision for Extended Reach 3D Manipulation
Résumé
Object selection and manipulation in 3D immersive environments generally suffers from a lack of precision,
primarily due to hand instability and tracking noise. Typically the lack of precision is exacerbated as the user begins to use
techniques that allow distant interaction, such as Ray Casting, HOMER, and Go-Go. This problem can be addressed using
velocity-based hand scaling such as PRISM, which has been applied to Ray Casting and HOMER previously. We present a study
of the combination of Go-Go and PRISM. In our research, we have found that Go-Go + PRISM yields a nearly 2:1 improvement
in precision over traditional Go-Go interaction when attempting to align two objects at a distance under time constraints
