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. The visual user interface enables a user to change the display of the control space, thereby controlling the operation of the device. Such a visual user interface in which a target scene provides context for a control scene can, for example, facilitate perception by a video camera operator of a current filmed scene in the context of the current filmed scene's surroundings, thereby enhancing the camera operator's ability to engage in critical and sophisticated camera work with great precision. The visual user interface can also include a space for making annotations regarding the interaction of the device with the spatial region, thereby enabling such annotations to easily be made contemporaneously with control of the device, so that a single person can perform both functions well. Additionally, the annotation capability can be implemented in a way that enables the user to handwrite the annotations, thus facilitating a wide range of expression in creating annotations and avoiding the problems associated with voice annotation systems.
