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.

Title: Seeing the Point: Understanding and Representing Gestures in Surface-Based, Distributed Collaboration

Speaker: Aaron Genest, PhD candidate, Department of Computer Science, University of Saskatchewan

Abstract: When people collaborate they often use gestures as an important part of their communication. Gestures can take many forms, but people often use a form of gesture called deixis – an indicative gesture that commonly takes the form of pointing – to identify objects, locations, or directions. This behaviour is particularly critical for communication when people are collaborating over a shared artifact, such as a map on a table. Map-based collaboration, or geocollaboration, occurs in many domains, including urban planning, emergency response, foreign and domestic policy, and a variety of research and industrial settings. In most of these settings, the collaboration can be described as surface-based (i.e., it occurs over a table or whiteboard).

Although collaborations are often collocated, they are increasingly distributed, taking place in multiple locations, at different times, or both. In distributed, surface-based geocollaborations, communication is usually improved through the use of embodiments: representations of remote users, their characteristics, and their activities. Although embodiments can show some deixis, current implementations are limited and as a result, distributed collaboration over shared artifacts requires more time, is less expressive, less successful, and more error-prone than collocated collaboration. In some domains, such as emergency management and political negotiation, such problems can mean the difference between success or failure.

This seminar presents my research into how to address these problems, including ethnographic analysis of how gestures are used, the design and evaluation of embodiment candidates for representing gestures in distributed settings, and the development of a toolkit, KinectArms, for capturing and showing gestures over distributed surfaces.
