I engineered a handheld phone stabilizer aimed at reducing the impact of hand tremors in individuals with Parkinson’s disease, applying inclusive design principles to prioritize comfort, usability, and accessibility. The device was developed to support daily smartphone use—such as reading, video calling, and taking photos—by mitigating unintentional hand movements through active control.

 

The system featured a mechatronic stabilization platform with real-time tremor compensation enabled by PID control and active damping. The design underwent iterative prototyping and refinement, and was tested with volunteers from a local Parkinson’s Society chapter to evaluate comfort, effectiveness, and user feedback. The project demonstrated the potential of low-cost, user-centered assistive technologies to enhance quality of life for individuals with motor impairments.
