Home heating is a major factor in worldwide energy use. Our system, PreHeat, aims to more efficiently heat homes by using occupancy sensing and occupancy prediction to automatically control home heating. We deployed PreHeat in five homes, three in the US and two in the UK. In UK homes, we controlled heating on a per-room basis to enable further energy(More)
The History Tablecloth is a flexible substrate screen-printed with electroluminescent material forming a grid of lace-like elements. When objects are left on the table, cells beneath them light to form a halo that grows over a period of hours, highlighting the flow of objects in the home. The Tablecloth explores an approach to design that emphasises(More)
A human-powered user interface device sources its power from the physical effort required to operate it. This paper describes a technique by which a geared DC motor and a simple circuit can be used to enable interaction-powered rotary input devices. When turned, the circuit provides a temporary power source for an embedded device, and doubles as a sensor(More)
We present the Pin&Play&Perform system: an interface in the form of a tablet on which a number of physical controls can be added, removed and arranged on the fly. These controls can easily be mapped to existing music sofware using the MIDI protocol. The interface provides a mechanism for direct manipulation of application parameters and events through a set(More)
The Drift Table is an electronic coffee table that displays slowly moving aerial photography controlled by the distribution of weight on its surface. It was designed to investigate our ideas about how technologies for the home could support ludic activities-that is, activities motivated by curiosity, exploration, and reflection rather than(More)
We introduce a new type of interactive surface technology based on a switchable projection screen which can be made diffuse or clear under electronic control. The screen can be continuously switched between these two states so quickly that the change is imperceptible to the human eye. It is then possible to rear-project what is perceived as a stable image(More)
In this paper we present novel input devices that combine the standard capabilities of a computer mouse with multi-touch sensing. Our goal is to enrich traditional pointer-based desktop interactions with touch and gestures. To chart the design space, we present five different multi-touch mouse implementations. Each explores a different touch sensing(More)

Rather than existing as a computer input device with a rigid shape, a predetermined selection of controls and a fixed layout, a <i>malleable control structure</i> is made up of a set of controls that can be freely arranged on control areas. The structure is physically adaptable by users during operation: control areas and controls can be introduced,(More)
Microsoft .NET Gadgeteer is a new prototyping platform that makes it easier to construct, program and shape new kinds of computing objects. It is comprised of modular hardware, software libraries and 3D CAD support. Together, these elements support the key activities involved both in the rapid prototyping and the small-scale production of custom embedded,(More)
