Providing electrical power is essential for nearly all interactive technologies, yet it often
remains an afterthought. Some designs handwave power altogether as an “exercise for …

We propose a new technical approach to implement untethered VR haptic devices that
contain no battery, yet can render on-demand haptic feedback. The key is that via our …

We present a new energy harvesting technology that generates electrical energy from a
user's interactions with paper-like materials. The energy harvesters are flexible, light, and …

Force feedback devices resist miniaturization, because they require physical motors and
mechanics. We propose mobile force feedback by eliminating motors and instead actuating …

We investigate implanted user interfaces that small devices provide when implanted
underneath human skin. Such devices always stay with the user, making their implanted …

Physical controls are widely used by professionals such as sound engineers or aircraft
pilots. In particular knobs and sliders are the most prevalent in such interfaces. They have …

EnergyBugs are energy harvesting wearables with features that invite children to move their
bodies to generate tiny, yet usable amounts of electricity. EnergyBugs not only convert …

We here present a series of design explorations focusing on batteryless interactions
powered by hand cranking body movements. The explorations concern not only the matter …

While the majority of pneumatic interfaces are powered and controlled by traditional electric
pumps and valves, alternative sustainable energy-harnessing technology has been …

The Cellulo robots are small tangible robots that are designed to represent virtual interactive
point-like objects that reside on a plane within carefully designed learning activities. In the …
