Affective Expressions in Conversational Agents for Learning Environments: Effects of curiosity, humour, and expressive auditory gestures
(University of Waterloo, 2021-12-13)Conversational agents -- systems that imitate natural language discourse -- are becoming an increasingly prevalent human-computer interface, being employed in various domains including healthcare, customer service, and ... -
Analyzing Barehand Input Mappings for Video Timeline Control and Object Pointing on Smart TVs
(University of Waterloo, 2021-09-21)Smart TVs are getting popular in recent few years. Given the emerging feature of distant bare hand control, one challenge is how to perform common tasks with this new input modality. Two tasks are discussed in this thesis ... -
Barehand Mode Switching in Touch and Mid-Air Interfaces
(University of Waterloo, 2020-05-28)Raskin defines a mode as a distinct setting within an interface where the same user input will produce results different to those it would produce in other settings. Most interfaces have multiple modes in which input is ... -
Contextual Factors Affecting Information Sharing Patterns in Technology Mediated Communication
(University of Waterloo, 2020-08-19)In this thesis, we investigate how and what contextual factors affect user’s information sharing. We build our work on six individual research projects which cover a variety of systems (search engines, social network sites, ... -
Designing Persuasively using Playful Elements
(University of Waterloo, 2021-09-14)Alongside productivity and communication, computers are a valuable tool for diversion and amusement. Game Designers leverage the multifaceted world of computing to create applications that can be developed persuasively; ... -
Dynamic Personalization of Gameful Interactive Systems
(University of Waterloo, 2019-07-17)Gameful design, the process of creating a system with affordances for gameful experiences, can be used to increase user engagement and enjoyment of digital interactive systems. It can also be used to create applications ... -
Eggly: Designing Mobile Augmented Reality Neurofeedback Training Games for Children with Autism Spectrum Disorder
(University of Waterloo, 2023-07-19)Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that affects how children communicate and relate to other people and the world around them. Emerging studies have shown that neurofeedback training (NFT) games ... -
Evaluating Singing for Computer Input Using Pitch, Interval and Melody
(University of Waterloo, 2022-09-02)In voice-based interfaces, non-verbal features represent a simple and underutilized design space for hands-free, language-agnostic interactions. This work evaluates the performance of three fundamental types of voice-based ... -
Evaluating the Speed and Accuracy of Touch Input at the Edge of a Table
(University of Waterloo, 2019-12-11)Tables, desks, and counters are often nearby, motivating their use as interactive surfaces. However, they are typically cluttered with objects. As an alternative, we explore touch input along the 'edge' of table-like ... -
Human-AI Interaction in the Presence of Ambiguity: From Deliberation-based Labeling to Ambiguity-aware AI
(University of Waterloo, 2020-09-11)Ambiguity, the quality of being open to more than one interpretation, permeates our lives. It comes in different forms including linguistic and visual ambiguity, arises for various reasons and gives rise to disagreements ... -
Investigating Selection above a Multitouch Surface
(University of Waterloo, 2012-10-25)Above-surface interaction is a new and exciting topic in the field of human-computer interaction (HCI). It focuses on the design and evaluation of systems that humans can operate by moving their hands in the space above ... -
An Investigation of Human Annotators' AI Teammate Selection and Compliance Behaviours
(University of Waterloo, 2024-01-18)Human-artificial intelligence (AI) collaborative annotation has gained increasing prominence as a result of its enormous potential to complement human and AI strengths as well as AI's recent development. However, it is not ... -
Learning from Green Technology Designers
(University of Waterloo, 2014-02-13)This thesis presents results from a qualitative case study on environmentally minded technology designers, and provides an account of how these designers think, differ and behave. Through semi-structured interviews, we ... -
Leveraging Asymmetry and Interdependence to Enhance Social Connectedness in Cooperative Digital Games
(University of Waterloo, 2019-05-24)Play is a fundamental component of human development and is an important means of forming healthy relationships throughout life. Research has shown that the types of digital games people play, how they play them, and who ... -
Merging the Real and the Virtual: An Exploration of Interaction Methods to Blend Realities
(University of Waterloo, 2022-01-20)We investigate, build, and design interaction methods to merge the real with the virtual. An initial investigation looks at spatial augmented reality (SAR) and its effects on pointing with a real mobile phone. A study ... -
People know how diverse their music recommendations should be; why don’t we?
(University of Waterloo, 2021-02-17)While many researchers have proposed various ways of quantifying recommendation list diversity, these approaches have had little input from users on their own perceptions and preferences in seeking diversity. Through a ... -
Practices Surrounding Social Use of the Nintendo DS Handheld Gaming System
(University of Waterloo, 2008-05-21)Ad-hoc wireless networking has recently become a standard feature of handheld video gaming systems. This capability, along with the portability of the devices, increases the number of places where people can easily engage ... -
Task-Centric User Interfaces
(University of Waterloo, 2014-05-22)Software applications for design and creation typically contain hundreds or thousands of commands, which collectively give users enormous expressive power. Unfortunately, rich feature sets also take a toll on usability. ... -
