Four browser-based tasks, no specialized hardware — each produces a continuous, quantitative trace that supplements (not replaces) clinical rating scales.
Reads guided passages, repeats "pa-ta-ka" rapidly, and sustains an "Ah" vowel. Extracts voice duration, loudness stability, pause ratio, and pitch (F0) variation to quantify dysarthric speech changes over time.
Microphone OpenReach and tap targets that appear at random screen positions using mouse, touch, or webcam-tracked movement. Captures reaction time, final positional error, tremor, and time spent within the target zone.
Mouse · Touch · Camera OpenTraces horizontal, vertical, and diagonal guide lines with the mouse or a touchscreen. Measures completion time, path deviation from the guide, discontinuities, corrective turns, and time spent outside the drawing bounds.
Mouse · Touch OpenSits facing a webcam while pose tracking follows shoulder position over time. Measures upper-body sway and how level the shoulders stay, without any wearable sensors.
