TouchScribe: Augmenting Non-Visual Hand-Object Interactions with Automated Live Visual Descriptions

People who are blind or have low vision regularly use their hands to interact with the physical world to gain access to objects' shape, size, weight, and texture. However, many rich visual features remain inaccessible through touch alone, making it difficult to distinguish similar objects, interpret visual affordances…

Viago: Exploring Visual-Audio Modality Transitions for Social Media Consumption on the Go

As mobile phone use while walking becomes increasingly prevalent, users often divide their visual attention between their surroundings and phone displays, raising concerns around safety and interaction efficiency. Alternative input and output modalities, such as eyes-free touch gestures and audio feedback, offer a pro…

WorldScribe: Towards Context-Aware Live Visual Descriptions

Automated live visual descriptions can aid blind people in understanding their surroundings with autonomy and independence. However, providing descriptions that are rich, contextual, and just-in-time has been a long-standing challenge in accessibility. In this work, we develop WorldScribe, a system that generates auto…

Understanding (Non-)Visual Needs for the Design of Laser-Cut Architecture

Laser-cutting is a promising fabrication method that empowers makers, including blind or visually-impaired (BVI) creators, to create technologies that fit their needs. Existing work on laser-cut accessibility has facilitated easier assembly as a workaround for existing models. However, laser-cut models are still not d…

AccessibleCircuits: Adaptive Add-On Circuit Components for People with Blindness or Low Vision

In this paper, we propose the designs for low cost and 3D-printable add-on components to adapt existing breadboards, circuit components and electronics tools for users with blind or low vision (BLV). Through an initial user study, we identified several barriers to entry for beginners with BLV in electronics and circui…

Glissade: Generating Balance Shifting Feedback to Facilitate Auxiliary Digital Pen Input

This paper introduces Glissade, a digital pen that generates balance shifting feedback by changing the weight distribution of the pen. A pulley system shifts a brass mass inside the pen to change the pen's center of mass and moment of inertia. When the mass is stationary, the pen delivers a constant yet natural sensat…

Exploring the Design Space of User-System Communication for Smart-home Routine Assistants

AI-enabled smart-home agents that automate household routines are increasingly viable, but the design space of how and what such systems should communicate with their users remains underexplored. Through a user-enactment study, we identified various interpretations of and feelings toward such a system's confidence in…

Masque: Exploring Lateral Skin Stretch Feedback on the Face with Head-Mounted Displays

We propose integrating an array of skin stretch modules with an head-mounted display (HMD) to provide two-dimensional skin stretch feedback on the user’s face. Skin stretch has been found effective to induce the perception of force (e.g. weight or inertia) and to enable directional haptic cues. However, its potential…
