In this research we present the modules of virtual reality augmented cycling (VRAC) system for people post stroke including mechatronic rehabilitation system and virtual environment. VRAC modules are designed as modular system to suit most stationary bicycles in virtual reality (VR) cycles without changing its parts. VRAC consists of novel hardware components embedded with sensors that are use to gain of a stationary exercise bicycle. VRAC modules include balancing pedals module, rpm (rotation per minute) counter module, safety driving module , handlebar module and acquisition data module. The handle system is a novel type of hand dynamometer, which measures applied physical force to control dynamic motion of the rider in the virtual environment. The data from sensing systems are measured by Arduino microcontroller as a acquisition data module and sent its results to virtual environment processed by computer. The prototype of the system was successful in demonstrating that a modular mechatronic kit can monitor and record kinetic, kinematic and physiologic parameters of riders.

Mirror therapy (MT) is a method to train upper limb after Stroke incident. The combination of MT with virtual reality (VR) has given more immersion experience into the illusion, while MT needs participant concentration to truly sensate the illusion as real. The purpose of this research is to design and develop first prototype of VR-MT as physical therapy equipment for enhancing motor performance in upper limb after Stroke. Upper limb motion in VR-MT is captured by Microsoft Kinect. We involve five healthy participants as VR-MT tester to execute a therapy task by controlling virtual limb to hit apples or avoid bombs in virtual environment (VE) for 10 minutes. After the treatment of therapy task, participants do simple assessment by answering a questionnaire. The result of statistical analysis of the questionnaire can be concluded that four elements including controllability, natural operation, sense of delay.and spatial difference are important key to control the movement of virtual limb correctly in VR-MT.
