My research lies in the general area of Human Computer
Interaction (HCI). I specialize in utilizing interdisciplinary research methods
to broaden our understanding of perceptual and motor abilities, and applying
that understanding to the design of present-day and emerging technologies to
solve identified problems. These technologies include multi-touch tabletop
and mobile devices, describing both their hardware and software interfaces. This research has been conducted at all of Mitsubishi Electric Research Labs, the University of Toronto, and the Initiative in Innovative Computing at Harvard
University. I am presently concentrating on architecting the
end-to-end user experience on the Microsoft Surface project. |

Table-Centric Interactive
Spaces
Tables have historically played a key role in many real-time collaborative environments, often referred to as "war rooms". Today, these environments have been transformed by computational technology into spaces with large vertical displays surrounded by numerous desktop computers. However, despite significant research activity in the area of tabletop computing, very little is known about how to best integrate a digital tabletop into these multi-surface environments. In this project, we set out to identify various design requirements for the implementation of a system intended to support such an environment, and to design interactions and other mechanisms to enable rich environments to support user tasks.
This research was the focus of my PhD, and was conducted primarily as part of the DiamondSpace project at MERL with Dr. Chia Shen, often in collaboration with Clifton Forlines and Professor Ravin Balakrishnan. The papers below represent my published contributions to this project.

Direct-Touch and
Tabletop Interaction
Direct touch offers compelling opportunities for user interface designers. It has been demonstrated to aid with spatial memory, bimanual interaction, novice usability - and new and exciting uses are being discovered regularly. When direct-touch interfaces are enabled for multi-touch and multiple users, and laid flat as a tabletop surface, they offer a promising platform for group collaboration. In this body of work, I and my collaborators have explored fundamental principles of direct-touch, interface elements, and novel platforms which leverage its unique affordances. My contributions to this research area are below, done mostly as part of the DiamondSpace project at MERL with Dr. Chia Shen, often in collaboration with Clifton Forlines and Professor Ravin Balakrishnan. This work is in conjunction with that on table-centred interactive spaces, described above.

Mobile Phone Text Entry
Most mobile phones are equipped with a simple 12-button keypad, which is an inherently poor tool for generating phrases for a 26-letter alphabet. It is therefore surprising that nearly 500 billion text messages were estimated to have been sent worldwide from mobile phones in 2003. Given the persistent popularity of the traditional keypad, there is a need to invent techniques for efficiently entering text using this restricted set of keys. This pair of papers and my MSc thesis explore the use of chording input, both with buttons and tilt gestures, to make input to mobile phones on an existing keypad. The papers and thesis below, co-authored and supervised by Professor Ravin Balakrishnan, describe this project in detail.

Hunter Gatherer
Hunter gatherer is a tool that automates capture of selected web bits of pages into a new web page, grabbing info about the page so you don't have to: you can just focus on selecting the information you want. Then, when you want to, you can focus on that collection - editing, managing or sharing it. I was involved in this project in its very early stages. PI mc schraefel maintains a current webpage for Hunter Gatherer. Below you will find the publications from the project that I was involved with.

Massive Change
Explores the legacy and potential, the promise and power of design in improving the welfare of humanity.

Massive Change Helped devise a concept, and then developed a multi-media
presentation application, for the Markets Gallery of
the Massive Change project
(commissioned by the Vancouver Art Gallery and displayed at other galleries
around the world). |
