Abstract/Summary
The Hand Tremor Stabilizer project represents a significant advancement in assistive device technology, aimed at improving the lives of individuals affected by hand tremors due to conditions such as essential tremor or Parkinson's disease. Throughout the design process, our team engaged in a comprehensive approach that included rapid prototyping, iterative testing, and direct feedback collection from potential users. This process was instrumental in refining the device to meet specific user needs effectively.
Key customer requirements that guided the design of the Hand Tremor Stabilizer included ease of use, portability, washability, accuracy of motion control, comfortable grip, breathability, a natural feel during use, and affordability. To meet these specifications, the device was designed as a wearable wrist brace/glove that incorporates a novel damper mechanism. This mechanism is specifically engineered to detect and suppress unintended tremor movements in the fingers and wrist, thereby enabling smoother and more controlled writing and other fine motor activities.
The functionality of the Hand Tremor Stabilizer was validated through a series of pilot tests, including spiral line tracing, line tracing, and sentence writing tests, coupled with qualitative feedback from initial users. These tests demonstrated a notable improvement in writing accuracy among participants, without hindering the natural writing process. Moreover, the device was found to be effective in dampening tremors, thereby confirming its potential to significantly enhance the quality of life for individuals with hand tremors.
