Accessible Real-Time Eye-Gaze Tracking For Neurocognitive Health Assessments, A Multimodal Web-Based Approach, Daniel C. Tisdale Jun 2024

Accessible Real-Time Eye-Gaze Tracking For Neurocognitive Health Assessments, A Multimodal Web-Based Approach, Daniel C. Tisdale

Master's Theses

We introduce a novel integration of real-time, predictive eye-gaze tracking models into a multimodal dialogue system tailored for remote health assessments. This system is designed to be highly accessible requiring only a conventional webcam for video input along with minimal cursor interaction and utilizes engaging gaze-based tasks that can be performed directly in a web browser. We have crafted dynamic subsystems that capture high-quality data efficiently and maintain quality through instances of user attrition and incomplete calls. Additionally, these subsystems are designed with the foresight to allow for future re-analysis using improved predictive models, as well as enable the creation …


Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor Aug 2018

Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor

Master's Theses

The ability for humans to communicate with another species has been an aspiration and well documented. One example is through training animals to make associations between a designated cue and conditioned response (Pryor, 1986). Two-way communication, however, in which both species can express wants/needs has been predominantly pursued with apes and dolphins. Studies conducted by Louis Herman demonstrated the capabilities of dolphins to comprehend complex semantic and syntactic commands in an artificial language system (Herman, Richards, & Wolz, 1984). Researchers working with primates have used American Sign Language, a computer keyboard system with discrete lexigrams, and a portable lexigram keyboard …


Correspondence Between Haptic And Visual Perception Of Stand-On-Ability: Do Hills Look As Steep As They Feel?, Jonathan Kenealy Doyon Dec 2016

Correspondence Between Haptic And Visual Perception Of Stand-On-Ability: Do Hills Look As Steep As They Feel?, Jonathan Kenealy Doyon

Master's Theses

Vision and haptics play a central role in perceiving environmental layout to guide action. Hajnal, Wagman, Doyon, and Clark (2016) demonstrated that visual perception of stand-on-ability is accurate compared to action capabilities, whereas haptic perception of stand-on-ability reliably underestimates action capabilities. This finding contradicts Gibson’s (1979) theory of equivalence in perceptual systems, which suggests that perception should be equivalent regardless of modality. Previous comparisons of visual and haptic perception tested the modalities in isolation. The current experiment directly compares visual to haptic perception of stand-on-ability by using one perceptual system to estimate the other. Observers viewed a surface set to …


Does Child Sponsorship Have A Positive Impact On The Quality Of Life And Social Behavior Of Sponsored Children? Evidence From Indonesia, Mario Carrillo May 2013

Does Child Sponsorship Have A Positive Impact On The Quality Of Life And Social Behavior Of Sponsored Children? Evidence From Indonesia, Mario Carrillo

Master's Theses

Relaxing an internal constraint of an individual at early stages of life is an approach that complements traditional policy interventions aimed to alleviate poverty. The Compassion International child sponsorship program focuses their work on the emotional, social, and spiritual development of sponsored children. This study investigates the impacts of child sponsorship on the quality of life and social behavior of sponsored children using age-eligibility as an instrument for sponsorship, a time preference experiment and a trust game. The study looks specifically at self-esteem, optimism, social trust, educational outcomes, patience and reciprocity of 286 sponsored children and 234 non-sponsored children between …
