Investigating Ways to Support the Use of Voice Assistants (VAs) among Individuals who are Blind
No full textVoice assistants (VAs) (e.g., Apple Siri, Google Assistant, Amazon Alexa, etc.) offer considerable potential to users. The hands-free nature of these technologies, enables users to perform tasks which would otherwise be difficult to accomplish. As individuals who are blind are already familiar with spoken output through the use of screen readers, it is surmised that mainstream voice interfaces (available on different VA platforms and applications) may serve as a promising modality to support tasks in a variety of settings. My dissertations research draws upon two bodies of work: (1) understanding the interaction experiences of individuals who are blind using VAs, and (2) examining ways these mainstream technologies can support indoor navigation and their information needs. I aim to investigate how VAs can be extended to enhance the indoor navigation experience through airports. These venues present interesting navigational challenges to travelers (e.g., large unfamiliar space, presence of noise and obstacles etc.). The findings of this research contribute to addressing the indoor navigation challenges for individuals who are blind. In addition, there is potential for findings to address the needs of the general population, who may also experience difficulties navigating within these settings
DEVELOPING AN APPROACH TO SUPPORT INSTRUCTORS TO PROVIDE EMOTIONAL AND INSTRUCTIONAL SCAFFOLDING FOR ENGLISH LANGUAGE LEARNERS THROUGH BIOSENSOR-BASED FEEDBACK
No full textDelivering a presentation has been found to be one of the most anxiety-inducing tasks faced by English language learners (ELLs). Researchers suggest that instructors should be more aware of the emotional state of ELLs to provide the appropriate level of emotional and instructional scaffolding support needed to improve presentation performance. Challenges can be faced by instructors attempting to determine the emotional state of ELLs solely through observation of their facial expressions and behaviors. To address the ambiguity in this process, the research described in this dissertations focuses on identifying the potential of using biosensor-based feedback to support instructors. A novel approach has been adopted to classify the intensity and characteristics of public speaking anxiety and foreign language anxiety among ELLs, with a view to provide tailored feedback to instructors. A focus group interview was conducted to identify instructors' needs for solutions providing emotional and instructional support for ELLs. This was followed by an ideation and design session, where prototypes incorporating biosensing technology were designed to support teaching. Findings informed the design of a more refined prototype system, which was evaluated with 17 English language instructors. The contributions of this research include: (1) the demonstration of the feasibility of using electrodermal activity to measure emotional states of ELLs during a classroom presentation; (2) the development of an algorithm for classifying degree of anxiety and predominant type of speaking anxiety among learners; (3) the development of an approach to investigate methods to measure levels of anxiety among ELLs through the use of a biosensor and to design and evaluate solutions to support educators using this technology; and (4) design guidance for an educational system using EDA data within an ESL/EFL environment
Ovarian Clear Cell Adenofibroma of Low Malignant Potential developing into Clear Cell Adenocarcinoma
No full textOvarian clear cell adenofibroma is uncommon, and borderline clear cell adenofibroma (low malignant potential) is extremely rare. Borderline clear cell adenofibromas may represent the precursor lesion of clear cell adenocarcinoma of the ovary, but this has not been established. We present a case of a woman in her mid-fifties with a clear cell adenofibroma ranging from benign to borderline to frankly invasive. While some clear cell adenocarcinomas are thought to arise from endometriosis, this range of findings supports the theory that some ovarian clear cell adenocarcinomas originate from borderline tumors.Peer reviewe

Towards Developing Guidelines for Addressing Situationally Induced Impairments and Disabilities (SIID) and Severely Constraining Situational Impairments (SCSI)
No full textThis research aims for a richer understanding of the variety and complexity of situational impairment events. Mobile users are often placed in less than ideal conditions where environmental variability can negatively affect the completion of an interaction. These interaction issues have been termed "Situationally Induced Impairments and Disabilities (SIID)". In addition, the omnipresent use of mobile devices seems to have produced a new complexity by-product termed "Severely Constraining Situational Impairments (SCSI)". Little research to date has attempted to examine SIIDs as events or from a generalizable classification perspective. Nor has much research attempted to explore the by-product of amplified complexity that the increase in usage and functionality offered by mobile technology is engendering. This research represents the culmination of three studies that have resulted in guidelines so that the design of mobile human-computer interaction can (1) better recognize the new complexity of the diverse facets that present during mobile interaction and (2) effectively account for the presence of SIID and SCSI events in the design of mobile device interaction
APPLYING VIRTUAL REALITY TO MOTIVATE AND PREPARE INTERNATIONAL STUDENTS FOR COMMUNITY ENGAGEMENT
No full textThere are numerous benefits to students participating in community engagement activities. However, levels of participation among international students are known to be lower compared
to their domestic counterparts. Virtual reality (VR) has been shown to have the potential to
encourage behavioral change among individuals in a range of contexts. Researchers have yet to
examine the impact of virtual reality to promote community engagement among international
students. The aim of the research described in this dissertation is to investigate the role virtual
reality technology plays in encouraging international students to volunteer in a community that is
different from their own. Four studies are described as part of this work. This dissertation
contributes to three areas: (1) exploring the impact of VR on international students? attitudes and
behaviors, (2) identifying ways and suggestions on how to integrate VR within the servicelearning field, and (3) the design of a module on how to integrate VR with other classes
connected to service learning. Insights gained from this work have broad implications for
community engagement and institutions that host international students or prepare students for
study abroad experiences. This work will help support instructors who are interested in
integrating VR technology and community engagement within their field

Investigating the navigational habits of individuals who are blind in India
No full textAssistive navigational technologies offer considerable promise to people with visual impairments. However, uptake of these technologies has traditionally been lower in low and middle-income countries (LMICs). In this paper, I describe a qualitative study undertaken with 14 people who identify as legally blind in an LMIC (India) to understand their requirements, experiences, and strategies undertaken when navigating with and without technology. I highlight key nuances that impact navigational habits including strategies to navigate within busy urban environments, strategies to address the impact of the rainy season, techniques used to navigate at night, and dealing with the impact of limited infrastructure
Investigating Mental Models of Risk Among Security-Expert Users
No full textUsable security research endeavors to make interaction with technology more intuitive and trustworthy. Studying this area is critical given the increasing amount of sensitive data we trust to networked devices and services, and our general propensity to discard online safeguards we find burdensome. A valuable facet of this research is qualitative study of users' mental models. This approach gathers description and observation of user behavior, and creates an interpretive picture of how users understand their technology. Users' experiences with their mobile devices shape these beliefs, and that constructed understanding in turn may profoundly influence users' technological choices and expectations. Security-expert users are a particularly interesting cohort because experience may sensitize them to risk and guide their technology choices in unique or prescient ways. With these issues in mind, three qualitative inquiries have been made to better understand how advanced mental models of network security may influence user behavior. First, we investigated experts' (n=20) understanding of mobile security and how their concerns shaped everyday use of those platforms. They experienced typical usability problems and situational impairments with their mobile devices, but also described caution towards data sharing. The avoidance was based on factors including the sensitivity of the data to be shared and variable distrust of underlying network connections and technology platforms. We then secondly compared the outlook and behavior of a similar cohort (n=38) of both experts and non-experts when considering adoption of biometric authentication on their mobile devices. Experts were found to more readily accept fingerprint unlocking as an improved mode of authentication than non-experts. However, experts resisted its use for sensitive transactions, and their enthusiasm did not transfer to facial recognition. Our third study examined perceptions of experts, in two rounds (n=8, and n=19), serving security consultant roles (CISOs) for small businesses. CISOs tended to view government-authored security guidance as harder to use but more authoritative than commercial sources, and saw small businesses as highly vulnerable to online threats. This work concludes by comparing the observations and implications drawn from these studies to examples of security guidance. Guidance of this type was described as a key reference and basis for advisement by CISOs to non-expert small business owners. Based on the deductive comparison, a preliminary set of guidelines for presenting models of online risk are offered. These guidelines indicate ways to make security guidance more effective, based on experts' perspectives that should be broadly applicable and useful as awareness of online threats becomes more prevalent
