Exergames have gained popularity as interactive systems that promote physical activity through gaming. This paper presents the development process of a hand motion-sensing glove designed to complement an existing ankle-worn motion sensor. The glove aims to provide a more immersive exergaming experience by accurately tracking hand movements. Several prototypes were developed and iteratively improved to refine the design and functionality. This paper outlines the background of exergaming technology, reviews related work, and details the iterative development of the glove, discussing challenges encountered and improvements made. Finally, future steps for completing the final prototype are discussed.
