VoicePen: Augmenting Pen Input with Simultaneous Non-Linguisitic Vocalization
Non-linguistic vocalizations, such as vowel sounds, variation of pitch, or control of loudness have the potential to provide fluid continuous input concurrently with pen interaction. VoicePen is a set of interaction techniques that leverage the combination of voice and pen input when performing both creative drawing and object manipulation tasks.

Devices That Tell On You: The Nike+iPod Sport Kit
Increased wireless gadgetry can erode our privacy. In this work, we explore the privacy properties of the Nike+iPod Sport Kit.

Design Patterns for the Digital Home
Whether design patterns are a useful means to disseminate design knowledge in emerging domains such as the digital home is an open question. We have developed a set of design patterns for the digital home and have evaluated the extent to which these are useful to design professionals empirically with 44 designers.

Twice
Twice is a toolkit for wizarding UbiComp environments.

Ubiquitous Broadcast Computing
As we traverse physical spaces we seek and consume information relatively anonymously and harmlessly. We hypothesize there is much more information that providers are willing to make public electronically to local physical areas. However, we believe it is challenging to provide public information while ensuring provider security and user privacy under current wireless network schemes. We have developed a toolkit for broadcasting public information over private wireless networks and a suite of applications that employ this approach.
