AR-Based Embodied Avatar Assistance for Nonspeaking Autistic People? Design and Feasibility Study

Many nonspeaking autistic individuals rely on Communication and Regulation Partners (CRPs) to develop spelling-based communication using physical letterboards, but this support is often geographically inaccessible. We developed a remote presence system using Augmented Reality (AR) to enable immersive, collaborative sp…

Grab-and-Release Spelling in XR: A Feasibility Study for Nonspeaking Autistic People Using Video-Passthrough Devices

This paper explores the feasibility of using video-passthrough Extended Reality (XR) devices to support communication in nonspeaking autistic individuals. Prior XR work relied on expensive AR headsets and near-hand tapping interactions. We present LetterBox, a novel application for video-passthrough XR headsets (e.g.,…

From Letterboards to Holograms: Advancing Assistive Technology for Nonspeaking Autistic Individuals with the HoloBoard

About one-third of autistic individuals are nonspeaking, i.e., they cannot use speech to convey their thoughts reliably. Many in this population communicate via spelling, a process in which they point to letters on a letterboard held upright in their field of view by a trained Communication and Regulation Partner (CRP…

Personalizing an AR-based Communication System for Nonspeaking Autistic Users

Nonspeaking autistic individuals ("nonspeakers") represent about one-third of the autistic population, and most are never provided with an effective alternative to speech, hindering their educational, employment, and social opportunities. Some individuals have learned to spell words and sentences by pointing to letter…

Interactive AR applications for Nonspeaking Autistic People? A Usability Study

About one-third of autistic people are nonspeaking, and most are never provided access to an effective alternative to speech. Thoughtfully designed AR applications could provide members of this population with structured learning opportunities, including training on skills that underlie alternative forms of communicat…
