We prototype and evaluate a desktop input and output device in the form of an architect desk lamp. The bulb is replaced with a pico laser projector, a button replaces the switch, and the mechanical design allows it to remain in position between user manipulations. By also tracking lamp position and orientation, we explore novel interaction techniques to extend and augment conventional devices in a physical desktop environment. Content can be transferred from devices to the surrounding environment, and the representation of content can be adapted to surfaces, objects, and other devices using the lamp projection target and lamp proximity. A user study with the prototype and semi-structured interviews examine proposed interactions and consider potential scenarios and applications. Based on the results, we propose further design considerations for direct manipulation systems to extend and augment desktop computing.
