Reading On-the-Go
 |
Many mobile devices are actually used while stationary. In this
project we examine the use of different display technologies for
reading while walking through the environment.
|
The Gesture and Activity Recognition Toolkit
 |
GART is a user interface toolkit designed to facilitate the creation of
applications that utilize gesture recognition. The toolkit provides a
high level abstraction to the machine learning algorithms and tools to
support the training and recognition process.
|
Typing with Limited Visual Feedback
 |
In this work we examine the ability to type with limited visual
feedback. In a mobile environment, the user may not be able to pay
full attention to his mobile device. In a laboratory setting we
explored manipulating the visibility of the user's mobile keyboard and
display.
|
Mini-QWERTY Keyboards
 |
The mini-QWERTY keyboard is a common text entry device for several
smart phones. In this work we evaluate both novice and expert text
entry rates. We also are working on refining an empirical model of
mini-QWERTY typing and exploring automatic error correction.
|
Twiddler
 |
The Twiddler is a one handed chording keyboard that has been adopted
by the wearable computer community. We have conducted longitudinal
evaluations of learning rates and studied both novice and expert
typing.
|
Dual Purpose Speech
 |
Dual-purpose speech is an interaction technique designed to provide a
user support during a face-to-face conversation with another
individual. We capture portions of the user's conversation and use
speech recognition to reduce manual input and provide services to the
user.
|
CFXGA X Server
 |
In an effort to change my wearable over to the Intel Stargate research
platform, I created and X server for the IO Data CFXGA compact flash
VGA card.
|
Everyday Use of Wearables
 |
This project was a case study examination of the use of a wearable
computer by an expert user. Through this evaluation, we uncovered
data showing how the wearable is used in support of conversation and
as a memory aid.
|
KeyMenu
 |
The KeyMenu is a keyboard based menu designed around the Twiddler keyboard.
|
Mobile Capture for Evaluation
 |
In this project, I developed a system to that could record the
interaction a user has with his wearable computer and capture data
about his interaction with the environment.
|
Guided by Voices and West Wind
 |
Guided by Voices is audio based augmented reality game. It utilizes a
custom, radio based location system to trigger audio events as the
user moves through her environment.
