We developed a wearable acoustic sensor, called BodyScope, to record the sounds produced in the user's throat area and classify them into user activities, such as eating, drinking, speaking, laughing, and coughing.Expand
We present a research and design study of the Living Memory Box, a device and service to assist families in preserving memories in a variety of media forms.Expand
In this paper, we present a study that examines how users conceptualize applications involving automated capture and playback of home activities and reveals a breadth of home applications that people desire.Expand
We present SemFeel, a tactile feedback system which informs the user about the presence of an object where she touches on the screen and can offer additional semantic information about that item.Expand
We present Virtual Shelves, a technique to trigger programmable shortcuts that leverages the user's spatial awareness and kinesthetic memory using a spatially-aware mobile device within the circular hemisphere in front of her.Expand
We present the 1Line keyboard, a soft QWERTY keyboard that is 140 pixels tall (in landscape mode) and 40% of the height of the native iPad keyboard.Expand
We present a qualitative study of mobile phone ownership, replacement and disposal practices geared towards identifying design opportunities towards sustainable mobile phone interfaces.Expand
We built a handheld system for representing geographical information called SpaceSense, which includes custom spatial tactile feedback hardware-multiple vibration motors attached to different locations on a mobile touch-screen device.Expand
We study the human capability associated with performing foot-based interactions which involve lifting and rotation of the foot when pivoting on the toe and heel and develop a system to learn and recognize foot gestures using acceleration data recorded by a built-in accelerometer on the mobile device.Expand
