Recent research has explored ways to obtain and use knowledge of person-object interactions. We present a novel pair of wearables, a glove and a bracelet, that detect when users interact with unobtrusively tagged objects. The glove can also report whether the grasp was with the palm or the fingertips. Both devices have been built and deployed. We present… (More)
The iBracelet and the Wireless Identification and Sensing Platform promise the ability to infer human activity directly from sensor readings.
We present Bonfire, a self-contained mobile computing system that uses two laptop-mounted laser micro-projectors to project an interactive display space to either side of a laptop keyboard. Coupled with each micro-projector is a camera to enable hand gesture tracking, object recognition, and information transfer within the projected space. Thus, Bonfire is… (More)
Ubiquitous computing applications often use a user's context to automatically adjust their behavior to the situation. We have developed three types of wireless sensor nodes that can be worn, carried, or embedded in the environment that can provide interesting contextual information: a rich multi-sensor node to infer human activity that can be worn by a… (More)
Science museum visitors are often pressed to attend scheduled events and to see as many exhibits as possible in a single visit, leaving little time to experiment, learn, and reflect upon deeper ideas and science concepts behind an exhibit. We have developed a museum-based application that uses a low-powered, wireless RFID transceiver called 'eXspot' that is… (More)
The MSP is a small wearable device designed for embedded activity recognition with the aim of broadly supporting context-aware ubiquitous computing applications. A ctivity-aware systems have inspired novel user interfaces and new applications in smart environments , surveillance, emergency response, and military missions. Systems that recognize human… (More)
Informal note taking is a significantly different task from note taking in structured settings. This type of activity requires a special set of requirements including a substantial lowering of hurdles to capture and access across a variety of environments. Cepher is a prototype note capture system that supports the capture and retrieval of short notes… (More)
