Improved Grip Stability in Healthcare: Mixed Reality Assistance Devices for Degenerative and Age-Related Hand Conditions

This study explores integrating Mixed Reality (MR) and Human-Computer Interaction (HCI) technologies to develop an advanced assistive device. The device improves grip stability for individuals suffering from Rheumatoid Arthritis (RA) and Osteoarthritis (OA). It preserves autonomy and improves overall well-being by combining MR with a servo motor locking mechanism to provide enhanced grip assistance. The concept incorporates digital overlays that deliver real-time guidance and feedback to aid physical manipulation and enhance rehabilitation, making it more immersive and tailored to individual needs. It outlines an iterative design approach that merges ergonomic design principles with sophisticated engineering, demonstrating MR's pivotal role in enhancing digital and physical interactions. Initial feedback from users has indicated significant enhancements in task performance and satisfaction, highlighting the device's capacity to promote independence and mitigate user discomfort. This study underscores MR's substantial potential to redefine the functionality of assistive devices, ultimately fostering greater autonomy and improved quality of life for individuals living with RA and OA.
