Modeling Touch Input for Users with Motor Impairments: Empirical Insights into Training Size Requirements
This CHI Extended Abstract addresses a practical question for ability-based design: how many touch observations do you actually need before you can build a user-specific model of someone's touch performance? Most touch modeling work, including Bayesi…

Giving Meaning to Movements: Challenges and Opportunities in Expanding Communication by Pairing Unaided AAC with Speech Generated Messages
Kabir and colleagues tackle a long-standing split in Augmentative and Alternative Communication (AAC): aided AAC — speech-generating devices, symbol boards, tablet apps — produces standardised, intelligible output but is slow, visually demanding, and…

Beyond Accuracy: Auditing Allocative Harms in Facial-Gesture Recognition for People with Motor Impairments
This paper challenges the conventional framing of facial-gesture recognition accuracy as a purely technical property, and reframes it as a sensorimotor alignment problem between user intention and algorithmic interpretation. The authors conducted a m…

Imagine, Interact: Eliciting Accessible Interactions from Users with Motor Impairments via Imagined Input Devices
This paper reports an end-user gesture elicitation study with eleven participants with upper-body motor impairments - including spinal cord injury, spina bifida, multiple sclerosis, cerebral palsy, Parkinson's, and traumatic brain injury - who were a…

Barrier pointing: using physical edges to assist target acquisition on mobile device touch screens
Froehlich, Wobbrock and Kane propose barrier pointing: a set of stylus-based target acquisition techniques that exploit the raised physical edge of a mobile touch screen to stabilise input for users with motor impairments. Standard touch-screen tappi…

A comparison of area pointing and goal crossing for people with and without motor impairments
Wobbrock and Gajos at the University of Washington present a controlled study comparing two fundamentally different target-acquisition paradigms — conventional area pointing (move into a confined region and click) and goal crossing (sweep the cursor …

Semantic & syntactic context-aware text entry methods
Jun Gong's Assets '07 demonstration paper proposes a context-aware extension to the dictionary-based predictive disambiguation (DBPD) text-entry methods — the family that included the once-ubiquitous T9 on mobile phone keypads. DBPD methods let users…

Demo of VJ-Voicebot: Control of Robotic Arm with the Vocal Joystick
This demonstration paper from the University of Washington presents VJ-Voicebot, a system that allows individuals with motor disabilities to continuously control a 5 degrees-of-freedom robotic arm using non-verbal vocal sounds. The system builds on t…

Humming Control Interface for Hand-held Devices
This paper from Stanford University presents a control-by-humming interface that allows hands-free operation of portable devices such as cell phones and music players through subvocal humming detected by a Bluetooth-connected insertion earphone/micro…

Dynamically Adapting GUIs to Diverse Input Devices
This paper presents an analysis framework and demonstration tool (Input Adapter Tool, IAT) for automatically modifying desktop application interfaces to accommodate alternative input devices. Most GUI applications assume keyboard and mouse input, cre…
