ABSTRACT:
A workspace expansion controller for human interface systems is provided. The controller resolves the physical workspace constraint by relocating the physical workspace of the device mapped inside the environment (virtual or robot) towards the area of interest of the operator without disturbing his or her perception of the environment. The controller is based on the fact that people are greatly influenced by what they perceive visually and often do not notice small deviations in their hand unless that small deviation has a corresponding visual component. With this new control approach the operator can explore much larger workspaces without losing spatial resolution through high scaling factors and thus avoid the drawbacks of indexing common with current approaches.
