  • Visual user interface for use in controlling the interaction of a device with a spatial region
    Patent number: 6624846
    Abstract: An improved visual user interface enables control of the interaction of a device with a spatial region. The visual user interface includes a display of a control space and a display of a target space. The content of the displayed target space can be a representation of some or all of the spatial region. The content of the displayed control space and displayed target space can also be established such that the displayed target space provides context for the displayed control space. The device is operated in accordance with the state of the displayed control space.
