Hybrid Cursor Control for Precise and Fast Positioning without Clutching

Abstract

In virtual environments, selection is typically solved by moving a cursor above a virtual item/object and issuing a selection command. In the context of hand-tracking, the cursor movement is controlled by a certain mapping of the hand pose to the virtual cursor position, allowing the cursor to reach any place in the virtual working space. If the virtual working space is bounded, a linear mapping can be used. This is called a proportional control. While proportional cursor control is very intuitive and easy to use, unfortunately, it often lacks accuracy. Selection of small virtual buttons or objects becomes unfeasible. Therefore often a relative con- trol is employed, where only the directions of real and virtual movement must correspond. This way the accuracy does not depend on the ratio between real and virtual working volume sizes/resolutions. To allow for relative cursor movements in the entire virtual working space usually some kind of clutching mechanism is employed (i.e. a certain action couples/de-couples the virtual to/from real movements). However, the lack of force feedback and physical buttons leads to severe problems of clutching in bare-handed interaction. To this end, we introduce a novel technique not incorporating any clutching mechanism.

This technique is protected by an european patent application. If you intend to use it commercially please contact one of the authors.
