back to top  Poke

Poke is a way of sharing emotional touches over phone calls. It delivers touches through an inflatable surface on one side of the phone and receives finger-pressure inputs on the opposite side of the phone, all while allowing callers to maintain a conventional phone-calling posture. Poke provides three key user interactions (poke, poke and vibrate, and poke back) and delivers affective touches through its inflating patterns and vibrations on the top of the inflatable surface. This opens possibilities for developing pleasant, affective tactile languages over phone calls.

back to top  MoleBot

What would it be like to have a mole live under your table and push around objects on the table surface? MoleBot, a robotic creature based on an organic user interface (OUI), lives in a coffee table and interacts with small items placed on the table surface. To ensure fluid motions of the molehills cast by the MoleBot, the table surface combines horizontal rigidity with the vertical flexibility of movable pins. Users are enabled to kinetically interact with this creature via a joystick or gestural commands.

back to top  Tactile Texting

Tactile Texting enables people to input text in touchscreen-based mobile phones without having to look at the screen. The text input is done with only one hand, meaning you can input text while using your free hand and eyesight for other activities, such as biking or walking. You write characters by moving your thumb across the "gullies." When you push the button on the back, the character is sent to a mobile phone via Bluetooth.

back to top  LEDswim

LEDswim is swimwear (swimsuit and goggles) designed to assist a professional swimmer during his or her training. The swimsuit contains heart rate sensors, which use a conductive fabric structure integrated into the fabric of the suit for maximum comfort. The goggles process this heart rate data and signal the user to either slow down or speed up to keep the training intensity at a desired level (heart rate zone). It does this using two small LEDs inside the goggles, near the edge of the user's visual field: orange for faster, red for slower (colors for maximizing contrast to surroundings). No lights means the swimmer's pace is in the desired zone. The data is updated continuously and is easily seen while swimming (no wrist watch required).
