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 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)
Nowadays, an increasing number of people use ensembles of differently sized mobile devices to accomplish different tasks. With advances in display and input technologies, such as flexible and deformable OLED and E-ink displays, we can close the gap between different form factors and offer devices that can be deformed and transformed for different purposes.(More)
Artifacts made using PaperPulse: (a) An interactive game (b) A birthday invitation card with a code-slot to reveal the date (c) A diet-card to keep track of daily eating habits. Abstract This paper covers PaperPulse [3], a design and fabrication approach that enables designers to produce standalone interactive paper artifacts by augmenting them with(More)
