Abstract: ABSTRACT The present invention relates to a surface-adaptive computer mouse incorporating electrorheological (ER) fluid skates (111) configured to dynamically modulate friction at the interface between the device and a supporting surface for active tremor suppression. The system utilizes onboard inertial sensing (104) and frequency-domain analysis (106) to distinguish involuntary tremors from intentional movement. A lightweight predictive machine-learning model operates in conjunction with reactive detection algorithms to enable pre-emptive activation of the ER-fluid damping mechanism prior to tremor onset. Upon activation, an electric field induces a rheological phase transition within the ER fluid, increasing resistive friction and dissipating high-frequency kinetic energy before motion is registered by the optical sensor (105). Individual skates may be independently controlled to provide directional asymmetric damping. The system further includes substrate-aware calibration configured to maintain substantially consistent damping performance across different surface materials, thereby improving motion stability, precision, responsiveness, and ergonomic usability without reliance on passive weighting or software-only filtering techniques.
