Statera Manus: Finding Balance

In Latin,

Statera translates to "balance" and "scales." We chose this name because it perfectly embodies our core mission: to restore digital balance and accessibility to individuals with hand tremors, essential tremor, parkinsons, MS, or withdrawals.


We Believe

that technology should empower, not frustrate. By compensating for involuntary movements, the adaptive Statera joystick acts as the scales, leveling the playing field and allowing users to navigate the digital world with confidence, precision, and ease. We believe in the power of design.


Built for Accessibility

Every feature designed to give users with tremors confident, precise computer control.

Adaptive Filtering

1 Euro Filter with median spike removal adapts in real-time to your movement speed -- smooth when idle, responsive when intentional.

Auto-Calibration

Automatic center recalibration detects when the stick is still and corrects drift -- plus manual center and range calibration.

Browser-Based Config

No software install needed. Connect via Web Serial, adjust profiles, remap buttons, and upload -- all in your browser.

Expandable I/O

Add micro switches, buttons, IR sensors, or sip-puff interfaces. Map any input to any function.

Live Testing

Built-in snake game and interactive button map let you verify everything works before you rely on it.

How It Works

Three steps from unboxing to full mouse control.

1

Plug In

Connect the Statera Joystick to your computer via USB-C. Extra sensors like micro-switches or sip-puff switches plug directly into the expansion ports.

2

Configure

Choose a tremor profile, remap buttons, and add expansion sensors. Sync your settings instantly to the joystick with one click.

3

Test

Play the built-in snake game to verify cursor control. Watch the live button map to confirm every input fires correctly.

Tremor Profiles

Pre-tuned for common tremor severities. Fine-tune any parameter live.

Profile Smoothing Deadzone Best For
1 - Steady None None (0) No tremor, full direct responsiveness
2 - Mild Light Small (10) Slight hand shake, good control
3 - Moderate Default Medium Medium (20) Noticeable tremor, balanced feel
4 - Heavy Heavy Large (30) Significant tremor or fatigue
5 - Severe Maximum Extra Large (40) Severe tremor / alcohol withdrawals
