Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

The main theme of my research over my career has been the interaction between people and computers and how digital media can be used to communicate between people. I have a strong interest in interactive 3-D graphics and the production of graphics hardware that reproduces all of our visual cues. This has lead to research in light field displays and computational holography.

Over my career I have worked in many different areas including aspects of computer graphics, user interfaces, software engineering and computer security. I established the first Virtual Reality (VR) laboratory in Canada while I was at the University of Alberta in 1986. This laboratory had the first HMD in Canada along with the first CAVE. We also developed the first open source VR package; the MR Toolkit that was distributed to several thousand researchers world wide.
