Embodied presence in virtual realityi This work is dedicated in memory of Dr. Anthony Whitehead, whose kindness, curiosity, and diverse wealth of knowledge inspired me and countless other Carleton University students to follow their passions and never let the rules get in the way.Embodied presence in virtual reality ii ACKNOWLEDGEMENTS To my advisor Chris Herdman, this work would not have been possible without you and the innovative research facility you built at VSIM. Thank you for always being willing to entertain an idea -even if it's a little out there -while also helping me learn to stick to the plot.Thanks to my committee Jo-Anne Lefevre and Craig Leth-Steensen for the thoughtprovoking questions and the insightful suggestions that improved the quality of this work.Etelle Bourassa, thank-you for all the times that I left your office feeling better than when I walked in. Cecilia Jorgenson and Chunyun Ma, I cannot imagine this journey without all the support, perspective, and laughter that was shared in our writing group. Thank you.Mike Chan-Reynolds, I would not be where I am without you. You gave me a toolbox and inspired my curiosity. Thank-you for believing in me when I was starting, encouraging me when I was stuck, and reminding me of my strengths as I move forward.Matt Brown, thank-you for your support and your sarcasm. Both were important. You helped me trust my training and kept me honest when I wanted to gloss over the details.Kevin Grignon, thanks for always going to bat for me and reminding me to ask for what I need. Thanks also to Cale Vardy and Eric Mahlstedt for their support as I finished this thesis.Finally, I owe much gratitude to my family. Ben, you know how to take me seriously when I need a confidant and how to send me into a fit of giggles like no one else can. Thanks for bringing the balance of extremes that reminds me to always be me.Mom, thanks for encouraging in me a feisty determination that must have backfired on you more than once. You told me to become a doctor instead of marrying one. I have you to thank for the grit that got me here and the rebellious spirit that keeps me conquering. Embodied presence in virtual reality iii ABSTRACT In this thesis, I proposed and tested the Embodied Presence Model (EPM), a framework aimed at examining the role of mental representations of the environment and body's effectors in supporting presence in virtual reality. A fundamental assumption of the EPM is that presence is a direct result of interactions between one's environment and one's effectors (e.g., hands) thus requiring a mental representation of both. The EPM was therefore informed by current perspectives from perceptual, cognitive, and neuropsychology literature on how the relationship between the environment and the body. Three experiments were conducted, each with approximately 50 participants. In all three experiments a virtual pointing task was used wherein participants made speeded pointing movements to virtual targets presented on the table in front of them the virtual environment....
