It Depends: Re_Authoring Play Through Clinical Reasoning in Wearable AR Rehab Games
A new study with 14 therapists reveals how to design AR games that adapt to individual patient needs in real-time.
A team of researchers from Northeastern University and other institutions has published a significant study titled 'It Depends: Re_Authoring Play Through Clinical Reasoning in Wearable AR Rehab Games' for the 2026 CHI Conference. The research systematically reviewed 132 existing augmented reality rehabilitation applications and conducted in-depth playtesting sessions with 14 licensed physical therapists. Their goal was to understand the gap between promising lab studies and limited clinical adoption, especially with the advent of new lightweight, glasses-form-factor AR hardware.
The analysis revealed that therapists don't use games as fixed products but actively 're-author' them in three distinct ways. First, in 'co-authored play,' they reshape movements, progressions, and difficulty in real-time alongside the patient. Second, 'situated play' involves adapting games across different medical specialties, patient conditions, and physical contexts (like a clinic vs. a home). Third, 'dual play' focuses on mediating both physical recovery and psychological support simultaneously. The researchers reframe therapists' common phrase 'It depends' from a hurdle into a core, generative design principle.
This study contributes a practical, clinical reasoning-based framework and concrete design guidelines for creating personalized, adaptive AR rehab experiences. The findings are crucial for developers aiming to build tools that align with therapists' complex, everyday decision-making workflows rather than forcing a one-size-fits-all approach. By centering the therapist's expertise in the design process, this work provides a clear pathway for translating experimental AR technology from controlled laboratory environments into effective, widely-used clinical practice.
- The study analyzed 132 AR rehab applications and involved playtesting with 14 licensed physical therapists.
- It identified three therapist-led 're-authoring' methods: co-authored, situated, and dual play for real-time adaptation.
- The work provides a design framework to bridge the gap between AR lab research and real-world clinical adoption.
Why It Matters
This provides a blueprint for building effective, therapist-approved AR rehab tools that can finally move from research labs into daily patient care.
