MATCH Core Design Philosophy
MATCH is built upon foundational principles of Zero-Effort Technology (ZET) and graded assistance. It aims to support executive function impairments by providing contextualized, necessary, and sufficient assistance, adapting to the user's behavior while minimizing cognitive load.

Average NASA-TLX Score (Low Cognitive Load)
MATCH achieved a low cognitive load score, indicating it requires minimal mental effort, outperforming 73.3% of comparable technologies.
Dynamic Adaptation & Guidance
The system's utility lies in its ability to autonomously guide users and adapt to unexpected behaviors, providing assistance that is both necessary and sufficient without being overly intrusive.
Adaptive Guidance in Real-World Scenarios
Challenge: Older adults with neurocognitive disorders often deviate from expected task sequences or use incorrect objects, requiring flexible assistance.
MATCH Solution: During evaluation, participants sometimes used hands or a hand towel instead of the rag for cleaning, or attempted to clean a different table. MATCH's context-aware inference system successfully detected these deviations and provided appropriate graded assistance (e.g., prompting users to consider the "appropriate object" or directing them to the correct task location).
Outcome: MATCH successfully guided 11 out of 12 participants autonomously through the table-cleaning task, demonstrating robust adaptability even in unscripted situations.
91.6%
Autonomous Guidance Success Rate
MATCH successfully guided almost all participants independently, adapting to their unique behaviors during task completion.
Optimized User Experience & Interface
While generally perceived as usable and intuitive, the study highlighted areas for refinement in interface design, particularly concerning the discoverability and visibility of virtual elements, influenced by current hardware limitations.
| Feature | Current Implementation (HoloLens 2) | Future Potential (Apple Vision Pro/Improvements) |
|---|---|---|
| Field of View | Limited (52°) often requiring head turns to see virtual elements. |
Significantly wider (110°), enabling better peripheral vision and reduced head movement. |
| Peripheral Vision & Discoverability | Virtual elements, especially arrows, were sometimes difficult to perceive or locate due to limited FOV. |
Improved peripheral vision would enhance discoverability and reduce cognitive effort for users. |
| Eye Tracking Calibration | Inability to calibrate for specific eye conditions (e.g., complex vision correction, macular degeneration) led to exclusion of some participants. |
Advancements in inclusive technology aim for successful calibration across a wider range of eye conditions. |
2.50/7
Average CSUQ Interface Quality Score (1=best)
Participants were generally satisfied with MATCH's interface quality, though improvements are suggested for optimal user experience.
Social Significance & Roadmap for Future Research
MATCH holds strong social significance by promoting aging in place and reducing caregiver burden. Future work will focus on integrating AI, multi-modal interactions, and broader evaluations.
Long-Term Societal Benefits
Context: The global population is aging, with increasing costs associated with long-term care and significant caregiver burden. The WHO advocates for home-based interventions.
MATCH's Contribution: Participants expressed a strong desire for technologies like MATCH, recognizing its potential to allow older adults to remain in their homes independently for longer. This reduces the need for constant caregiver presence, thereby alleviating emotional and financial burdens on families and healthcare systems.
Impact: MATCH directly supports the objectives of the WHO's "Decade of Healthy Ageing" by enabling independent living for a vulnerable population, fostering their physical, mental, and emotional well-being within their familiar environments.
4.08/5
User Perception of Assistance Sufficiency
Users largely agreed that the assistance provided by MATCH was necessary and sufficient to guide them through their tasks.

Your Strategic AI Implementation Roadmap
A phased approach to integrating mixed reality assistive technology into your operations, from initial assessment to ongoing optimization.
Phase 01: Needs Assessment & Customization
Identify specific executive function challenges within your target population (e.g., older adults, rehabilitation patients). Customize MATCH scenarios, assistance types, and user interface preferences (e.g., preferred colors, interaction methods) based on individual cognitive profiles and environmental context.
Phase 02: Pilot Deployment & User Training
Implement MATCH in a controlled pilot environment. Conduct initial user training and familiarization sessions, focusing on intuitive interactions and understanding graded assistance. Gather immediate feedback on utility, usability, and cognitive load in real-world scenarios.
Phase 03: Iterative Refinement & Integration
Based on pilot data, refine MATCH's algorithms, assistance semantics, and hardware compatibility. Explore integration with existing Ambient Assisted Living (AAL) technologies (e.g., smart home sensors) to enhance context-awareness and provide multi-modal interactions. Address potential hardware limitations with emerging devices.
Phase 04: Scaled Implementation & Long-Term Evaluation
Expand deployment to a larger user cohort. Conduct long-term studies to assess sustained impact on independence, caregiver burden reduction, and overall quality of life. Continuously monitor performance and user satisfaction for ongoing optimization and scenario expansion.
