Autonomous Radar-based Gait Monitoring System
(University of Waterloo, 2023-05-16)Features related to gait are fundamental metrics of human motion [1]. Human gait has been shown to be a valuable and feasible clinical marker to determine the risk of physical and mental functional decline [2], [3]. ... -
Towards geriatric use of exoskeletons: Improving human-device interaction with a tutorial and optimal control
(University of Waterloo, 2023-05-05)With the global geriatric population expected to reach 1.5 billion by 2050, there has been growing interest to tackle age-associated movement impairments by developing assistive technologies. Rehabilitative lower-limb ... -
Ecological Interface Design in Neuro-Critical Care
(University of Waterloo, 2023-05-02)Neuro-critical care is a data-intensive environment that requires physicians to integrate information across multiple screens, sources, and software. Despite the advances in neuromonitoring techniques, interfaces that ... -
Comparative Data Analysis of Older Driver's vs Younger Driver's Gap Acceptance Behavior at signalized left turns - A driving Simulator Study
(University of Waterloo, 2023-04-28)Drivers aged 65 and older are particularly prone to motor vehicle crashes, with approximately 20% of traffic fatalities occurring at intersections [11]. Intersections appear to be hazardous for drivers in this age group ... -
Modern Object and Visual Relationship Detection in Images from a Critical, Cognitive and Data Perspective
(University of Waterloo, 2023-04-27)Deep learning has dominated the landscape of computer vision for the past decade. Deep learning networks are the top performers on a slew of computer vision challenges (e.g., object detection or image segmentation) and on ... -
A Two-Armed Forward Dynamic Model of a Golf Drive: A Simulation and Optimization Tool for Golf Equipment and Biomechanics
(University of Waterloo, 2023-04-27)Golf club manufacturers and golf’s governing bodies both have clear interests in understanding how equipment design changes affect the performance of a golfer. Traditionally, to capture this interaction it was necessary ... -
Nanocomposite Based Infrared Photothermoelectric Detectors
(University of Waterloo, 2023-04-24)In the last decade, photothermoelectric (PTE) detectors that combine photothermal and thermoelectric conversion have been demonstrated for infrared and terahertz tracking. They are advantageous in terms of facile fabrication, ... -
Radiometric Compensation of Nonlinear Projector Camera Systems by Modeling Human Visual Systems
(University of Waterloo, 2023-04-21)Radiometric compensation is the process of adjusting the luminance and colour output of images on a display to compensate for non-uniformity of the display. In the case of projector-camera systems, this non-uniformity can ... -
Learning and Decision Making in Social Contexts: Neural and Computational Models
