Design of 3D immesive learning environment to enhanced hand skill after stroke

Abstract

This paper basically introduces the design of 3D model as user interface which intends to improvise the hand stroke rehabilitation system. A 3D immersive learning environment was developed based on needs analysis for rehabilitating hand function in stroke patients. Those environments developed by using Autodesk 3D MAYA software, Adobe Photoshop, Unity 3D and supported by wireless cyber glove. This new developed system is aimed to improve the functional recovery hand stroke patients by stimulating their cognitive and motor based on Fitts & Postner (1967) theory. The system used cyber glove as input device for user interaction with a virtual environment. The target level is designed in each task to increase patient motivation and individualize exercise difficulty to a patient's current state. The 3D cybertherapy system cosists of multiple environments involves with activities of daily living (ADL) routines. Nine (9) left hemiplegic stroke patients involved in this study. The evaluation showed that each participant had significant improvement in the measured parameter. The system is believed to help in improving the cognitive and hand rehabilitation aspects of hand stroke patients.
