Biography
I graduated from the Engineering Science (Computer Engineering Option) at the University of Toronto. After finishing my undergrad, I worked in Korea for Samsung Electronics at the Samsung Advanced Institute of Technology where I learned a lot about the "real" world but also about life in general. These days, I am finishing my Master's degree in Computer Science at Queen's University under the supervision of Roel Vertegaal at the Human Media Lab.

Physiologically Attentive User Interface (PAUI)
 
Predicting User Availability from physiology: We often need to let others know how
available we are to prevent being interrupted when we are busy, or to receive
notifications when we are available. Typically, instant messenger users let
other users know their current availability for interruptions by
manually toggling a status bar. The PAUI was an Attentive User
Interface that allowed a computer to automatically determine the
availability (or interruptability) of a user and display this information to
others. Click the image for a

Direct User Interface
 
Using Real Hands for Virtual
Interaction: One of the most interesting input devices is the EyeTap which is a type of
electric eyeglasses that allows users to experience mediated reality, whereby
a computer can computationally modify the user's perception of reality. In
this way it becomes possible to interact with virtual and real worlds, both at
the same time. One of my graduate school projects was to allow for
hands to be used for interaction, since hands are one of the most
natural extensions of the human body to interact with objects. I wrote some
computer vision code based around some OpenCV demos that tracked the hand, allowed for a virtual
marker to be manipulated and recognized basic gestures. Click the image for a

Video Jockeying
 
Real--Time Video Effects: I've always liked clubbing with my friends and I thought it would be neat to bring what I've been experimenting with at school to the nightclub. Nightclubs understand the importance of delivering an experience and so do Human Computer Interaction (HCI) researchers. I, along with a group of colleagues with a background in computer graphics and computer vision, co--founded a Video Jockey crew called adfusium.com that would perform at local nightclubs. We first began performing at Elixir in Kingston, writing the video jockeying code during the day while staying up late at night mixing the videos live. We used a mixture of live feeds and previously recorded video. Later, we helped set up permanent "Designer digital signage" systems at Elixir so that they could use the systems for pushing their advertising content while patrons lined up at the bar.

Direct Transfer Via Gloves
 
While working at Samsung Electronics I joined an existing group that was interested in an accelerometer based glove called Scurry. Scurry had 6 degrees of freedom. Scurry allowed for users to type in the air, and also move a mouse, without the need of a referential sensor (it was entirely MEMS based). However, if we look at how people use their hands, for millions and millions of years, much of it is to carry things. With this reasoning, I introduced a completely novel use of Scurry, that was to allow users to carry virtual information around and exchange it with others, much as they would do with their own hands.
