Abstract: The appearance of a cabinet for a device (e.g., a television) is dynamically controlled. One way of controlling the appearance of the cabinet is by providing a display panel on the cabinet. At least one input is obtained from an input device and processed by a controller. Based on these inputs, the controller sends signals to the display panel to change the appearance of the display panel. Lamps and heat-sensitive materials may be used to effectuate the desired change in appearance. The cabinet display features may be controlled to give the device the appearance of having a persona or of being an independent animate being. For example, lights in the cabinet could flash to suggest the device is laughing in response to the detection of a laugh track in a sitcom being displayed on the device. Patterns and colors can be generated to reflect moods according to the preferences of an interaction-design programmer.
