Interactive surfaces have great potential for co-located collaboration because of their ability to track multiple inputs simultaneously. However, the multi-user experience on these devices could be enriched significantly if touch points could be associated with a particular user. Existing approaches to user identification are intrusive, require users to(More)
We introduce the concept of tangibles that users can manipulate with their feet. We call them kickables. Unlike traditional tangibles, kickables allow for very large interaction surfaces as <i>kickables</i> reside on the ground. The main benefit of kickables over other foot-based modalities, such as foot touch, is their strong affordance, which we validate(More)
We present PaperPulse, a design and fabrication approach that enables designers without a technical background to produce standalone interactive paper artifacts by augmenting them with electronics. With PaperPulse designers overlay pre-designed visual elements with interactive widgets and specify functional relations between them using a logic demonstration(More)
Paddle is a highly deformable mobile device that leverages engineering principles from the design of the Rubik's Magic, a folding plate puzzle. The various transformations supported by Paddle bridges the gap between differently sized mobile devices available nowadays, such as phones, armbands, tablets and game controllers. Besides this, Paddle can be(More)
We present RetroFab, an end-to-end design and fabrication environment that allows non-experts to retrofit physical interfaces. Our approach allows for changing the layout and behavior of physical interfaces. Unlike customizing software interfaces, physical interfaces are often challenging to adapt because of their rigidity. With RetroFab, a new physical(More)
We present PaperPulse, a design and fabrication approach that enables designers to produce standalone interactive paper artifacts by augmenting them with electronics. With PaperPulse, users overlay visual designs with widgets provided in the design tool. PaperPulse provides three families of widgets, designed for smooth integration with paper, for a total(More)
