This project focuses on improving accessibility during one essential daily activity: eating. Rather than replacing user control with fully robotic feeding systems, this approach aims to assist individuals experiencing hand tremors while allowing them to maintain independence. Research shows that users prefer to retain control over bite size, timing, and transfer speed. This project seeks to develop a solution that stabilizes tremors while preserving user autonomy and dignity. This device can also be used for helpful data collection. The device can be used by physicians to monitor their patients’ tremor improvement or progression when using the utensil. System controls will be managed by a Weighted-Frequency Fourier Linear Combiner (WFLC). This is a non-linear adaptive filter that models quasi-periodic signals by tracking changing amplitude, phase, and frequency.
