Dexaucer

Dexaucer is a disc-shaped device designed to measure, train and enhance manual dexterity. It integrates sensors, haptic feedback and software to capture finger and hand kinematics during tasks and provide real-time feedback.

Physical design: 70 mm diameter, 11 mm thick, aluminum shell; weight ~200 g; top surface a capacitive touchscreen or touch-sensitive ring; internal IMU, force sensors on rim; vibrotactile actuators; battery and wireless module.

Data captured include movement trajectories, grip forces, tremor indices; software provides metrics such as mean velocity, smoothness (log jerk), path efficiency; tasks can be customized; data export.

Used in rehabilitation after stroke or injury; sports training; robotics development; prosthetics; occupational therapy.

Developed by Nova Labs researchers; concept 2012; prototype 2015; commercial release 2018; widely used by clinics and research groups.

Variants include Dexaucer Pro (professional/clinical), Dexaucer Mini (compact), Dexaucer Rehab edition with safety features.

Regulatory status varies by region; generally considered a medical device when marketed for rehabilitation, requiring privacy safeguards for biometric data; critics cite cost but users report improved assessment and motivation.
