Facebook, verify your identity for us!

Published by under Web Certificates

If you were a large company, used by millions around the world, wouldn’t you want to verify your identity and hinder look-alike websites from stealing your users’ passwords?

If Twitter can do it, Facebook can too!

Reza GhasemAghaei, PhD

Published by under Event Summaries,News

Date: Fri, 28 Apr 2017 16:00:19 -0400 From: Robert Biddle <robert.biddle@carleton.ca> Today, Reza GhasemAghaei successfully defended his PhD thesis, with only minor revisions required. Congratulations Reza!



Multimodal systems allow user interaction through various methods, or modalities, such as gesture, gaze, speech or head and body movements. There have been many frameworks proposed for the design of multimodal systems, but they focus principally on issues of tech- nical architecture. Some applications for multimodal systems, including education, however, involve issues relating to affective (emotional) user experience.

The thesis presents our experience with creating and applying a framework for multimodal software design and evaluation, with a focus on affect (i.e. emotion) in education. Our goal is to support the system designer, and indirectly also teachers and students. We outline our conceptual basis, adaptation of interaction design and evaluation techniques, and our experience over several case studies. In particular, we describe how our techniques were refined after each case study, and how the evaluation techniques led us to revisit our design techniques. We also gained new insight about the role of the teacher, leading us to develop a new affect visualization dashboard for teachers.
