A Computer Vision-Based System for Stride Length Estimation using a Mobile Phone Camera
This paper presents an affordable computer vision system for measuring stride length in Parkinson's disease (PD) patients using only a smartphone camera and a printed PVC mat. Gait analysis is a critical non-invasive method for PD diagnosis and asses…

Who Should Have Access to my Pointing Data? Privacy Tradeoffs of Adaptive Assistive Technologies
This UMBC study examines the often-overlooked privacy tradeoffs inherent in Adaptive Assistive Technologies (AATs) — software systems that monitor user performance data to automatically adapt their functionality. While AATs offer significant usabilit…

Simulation of Motor Impairment in Head-Controlled Pointer Fitts' Law Task
This poster paper proposes simulating motor impairments in a head-controlled mouse pointer system (Camera Mouse) to address the challenge that participants with motor impairments are not always available for accessibility research or software develop…

A communication tool for people with disabilities: lexical semantics for filling in the pieces
This paper presents a prototype communication tool designed to reduce the input burden for people with severe speech and motor impairments (SSMI) who use word-based augmentative communication systems. The core problem addressed is that even with word…

Guideline Aggregation: Web Accessibility Evaluation for Older Users
This paper proposes using set theory to create an aggregated accessibility evaluation category for older users by combining barrier types identified for motor impaired and low vision users within the Barrier Walkthrough (BW) method. Traditional valid…

Understanding Design Considerations for Adaptive User Interfaces for Accessible Pointing with Older and Younger Adults
This paper investigates how older and younger adults want adaptive user interfaces (AUIs) to detect and respond to pointing difficulties when using computers. Pointing problems — such as misclicks, erratic cursor movements, and difficulty with target…

GazeTheWeb: A Gaze-Controlled Web Browser
This demonstration paper presents GazeTheWeb, an open-source web browser designed to be operated entirely through eye gaze input, targeting people with severe motor impairments who cannot use conventional mouse and keyboard input. Built on the Chromi…

Designing an Adaptive Web Navigation Interface for Users with Variable Pointing Performance
This paper investigates how to design adaptive web navigation interfaces for people who experience variable pointing ability — difficulty using a mouse to click targets on screen that fluctuates over time due to conditions like early-stage Parkinson'…

Vocal Programming for People with Upper-Body Motor Impairments
This paper presents VocalIDE, a prototype voice-based integrated development environment (IDE) designed to enable people with upper-body motor impairments to write and edit computer code using speech commands rather than a keyboard. Only 4% of profes…
