Emerging technologies have given us a whole host of new ways for people to be
creative. From the immersive worlds of AR/VR to the synthesis powers of largelanguage
models and generative AI, these new tools hold the potential to reshape
human expression and creativity. But how can we ensure that these new modalities
are accessible to everyone, even those who aren’t able bodied? This thesis advocates
for a human-centered approach to the development of many-modal systems. I will
probe how our machines support, direct, or inhibit creativity as a mode of problem
solving through 6 novel multimodal prototype interfaces and …
Diegetic Sonification For Low Vision Gamers, Jhané Dawes
Diegetic Sonification For Low Vision Gamers, Jhané Dawes
Master's Theses
There are not many games designed for all players that provide accommodations for low vision users. This means that low vision users may not get to engage with the gaming community in the same way as their sighted peers. In this thesis, I explore how diegetic sonification can be used as a tool to support these low vision gamers in the typical gaming environment. I asked low vision players to engage with a prototype game level with two diegetic sonification techniques applied, without the use of their corrective lenses. I found that participants had more enjoyment and experienced less difficulty …

Facilitating Information Retrieval In Social Media User Interfaces, Anthony Costello
Facilitating Information Retrieval In Social Media User Interfaces, Anthony Costello
Electronic Theses and Dissertations
As the amount of computer mediated information (e.g., emails, documents, multi-media) we need to process grows, our need to rapidly sort, organize and store electronic information likewise increases. In order to store information effectively, we must find ways to sort through it and organize it in a manner that facilitates efficient retrieval. The instantaneous and emergent nature of communications across networks like Twitter makes them suitable for discussing events (e.g., natural disasters) that are amorphous and prone to rapid changes. It can be difficult for an individual human to filter through and organize the large amounts of information that can …

Development Of A Cognitive Work Analysis Framework Tutorial Using Systems Modeling Language, Wilfred Henry Wells
Development Of A Cognitive Work Analysis Framework Tutorial Using Systems Modeling Language, Wilfred Henry Wells
Electronic Theses and Dissertations
At the present time, most systems engineers do not have access to cognitive work analysis information or training in terms they can understand. This may lead to a disregard of the cognitive aspect of system design. The impact of this issue is system requirements that do not account for the cognitive strengths and limitations of users. Systems engineers cannot design effective decision support systems without defining cognitive work requirements. In order to improve system requirements, integration of cognitive work requirements into the systems engineering process has to be improved. One option to address this gap is the development of a …
