VisionAid: A Multimodal Assistive Application Supporting Safe Road Navigation for Visually Impaired People in Bangladesh
VisionAid is an Android pedestrian-safety app for blind and low vision (BLV) users in Bangladesh, where road crossing is dangerous because traffic is unstructured: lane discipline is rare, drivers run signals, and crosswalks are inconsistent. The aut…

SocialCue: Exploring the Design Space of Social Wayfinding Assistants for Blind and Low Vision People
SocialCue is a wearable technology probe that targets a problem most assistive navigation work ignores: not where to walk, but how to read and act inside an unfolding social scene. The authors argue that existing tools for blind and low vision (BLV) …

SoundSpace: What and Where Through Sound
SoundSpace is a real-time sensory substitution system designed to give blind and visually impaired users simultaneous awareness of what objects are present in a scene and where they are located, without relying exclusively on verbal scene description…

Look Here, Click Me: Improving Older Adults’ Perception of Manipulable User Interface Components through AI-Based Perceptual Guidance
This CHI 2026 Extended Abstracts paper from Sookmyung Women’s University (Seoul) tackles a concrete gap in older-adult digital literacy: existing programs teach step-by-step procedures ("tap here, then here, then here") that collapse the moment an ap…

Camera-Based Closed-Loop Fingertip Deflection Guidance: Pilot Demonstrations in Target Acquisition and Object Retrieval
This CHI 2026 Extended Abstracts poster from the Northwestern/University of Chicago team behind the NURing project presents a camera-enabled evolution of their fingertip-deflection guidance wearable. The authors argue that most eyes-free guidance sys…

HapticLens: Interactive Vibrotactile Haptic Generation from Spatially Localized Video Motion
HapticLens is an interactive method for generating single-actuator vibrotactile signals from arbitrary video content by letting a designer select a spatial region of interest and converting motion within that region into a vibration waveform in real …

The ORBIT India Dataset: Understanding the Challenges of Collecting a Disability-First AI Dataset in Low-Resource Environments
This paper introduces ORBIT-India, the first teachable object recognition dataset contributed entirely by people who are blind or have low vision in India. It extends the UK/Canada-collected ORBIT dataset (Massiceti et al., 2021) to the Indian contex…

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…

DiG-Net: Enhancing Human–Robot Interaction through Hyper-Range Dynamic Gesture Recognition in Assistive Robotics
DiG-Net (Distance-aware Gesture Network) addresses a fundamental limitation in gesture-controlled assistive robotics: existing dynamic gesture recognition systems work reliably only within about seven metres of the camera, severely constraining their…

BBeep: A Sonic Collision Avoidance System for Blind Travellers and Nearby Pedestrians
This paper presents BBeep, an assistive suitcase-shaped system designed to help blind travellers navigate crowded public spaces such as international airports, train stations, and shopping malls. The authors argue that existing blind-navigation resea…
