We present an approach to 3D printing custom optical elements for interactive devices labelled <i>Printed Optics</i>. <i>Printed Optics</i> enable sensing, display, and illumination elements to be directly embedded in the casing or mechanical structure of an interactive device. Using these elements, unique display surfaces, novel illumination techniques,(More)
We introduce Acoustruments: low-cost, passive, and power-less mechanisms, made from plastic, that can bring rich, tangible functionality to handheld devices. Through a structured exploration, we identified an expansive vocabulary of design primitives, providing building blocks for the construction of tangible interfaces utilizing smartphones' existing audio(More)
We present a technology for designing curved display surfaces that can both display information and sense two dimensions of human touch. It is based on 3D printed optics, where the surface of the display is constructed as a bundle of printed light pipes, that direct images from an arbitrary planar image source to the surface of the display. This effectively(More)
We describe techniques that allow inexpensive, ultra-thin, battery-free Radio Frequency Identification (RFID) tags to be turned into simple paper input devices. We use sensing and signal processing techniques that determine how a tag is being manipulated by the user via an RFID reader and show how tags may be enhanced with a simple set of conductive traces(More)
We explore 3D printing physical controls whose tactile response can be manipulated programmatically through pneumatic actuation. In particular, by manipulating the internal air pressure of various pneumatic elements, we can create mechanisms that require different levels of actuation force and can also change their shape. We introduce and discuss a series(More)
User gestures are important in current gaming platforms, where users' movements are tracked and their actions trigger events in the games. We introduce <i>Power of 2 (Po2)</i>, a new haptic technology that augments illusive tactile sensations on gesture-based gameplays. Po2 utilizes two vibrating actuators on two hands and renders illusory tactile motion on(More)
In this paper, we present a novel near surface augmented reading system that brings digital content to physical papers. Our system allows a collocated mobile phone to provide augmented content based on its position on top of paper. Our system utilizes built-in magnetometer of a smartphone together with six constantly spinning magnets that generate designed(More)
We present <i>SqueezaPulse</i>, a technique for embedding interactivity into fabricated objects using soft, passive, low-cost bellow-like structures. When a soft cavity is squeezed, air pulses travel along a flexible pipe and into a uniquely designed corrugated tube that shapes the airflow into predictable sound signatures. A microphone captures and(More)
<i>PAPILLON</i> is a technology for designing highly expressive animated eyes for interactive characters, robots and toys. Expressive eyes are essential in any form of face-to-face communication [2] and designing them has been a critical challenge in robotics, as well as in interactive character and toy development.
We present freeform interactive speakers for creating spatial sound experiences from a variety of surfaces. Traditional surround sound systems are widely used and consist of multiple electromagnetic speakers that create point sound sources within a space. Our proposed system creates directional sound and can be easily embedded into architecture, furniture(More)
