BigClick
An accessibility companion for users with motor disabilities that overlays a customizable grid of large, dwell-to-click zones on top of any application — turning tiny UI targets into easy-hit buttons.
People with tremors, limited mobility, MS, Parkinson's, or arthritis who struggle with standard mouse precision
- Adaptive overlay grid sized to your tremor profile, with dwell-to-click timing you control
- App-specific profiles (Excel, Photoshop, browsers) that enlarge only the targets you actually click
- Voice-input fallback for typing when keyboard precision is also limited
- Caregiver mode that lets a family member adjust the overlay remotely
Neverclick and similar vision-based keyboard tools are proving the underlying computer-vision stack works reliably on consumer hardware, opening the door to accessibility-first overlays for users who can't use a mouse at all
Established niche market: SteadyMouse has operated ~20 years and is resold via specialist distributors like Active Hands and listed in Parkinson's UK's tech guide, confirming real ongoing need; built-in Mac and Windows Dwell features validate user demand at the OS level.SteadyMouse | Parkinson's UK Tech Guide ↗Change Keyboard settings for accessibility on Mac ↗
Crowded with adjacent solutions: SteadyMouse (anti-tremor filter + accidental-click blocking), Mac Dwell, Windows Ease-of-Access Dwell, Neverclick (keyboard-vision overlays), smylemouse (head/face), OPTIMA/n-ABLER joysticks, and dwellpy — none are exactly the 'customizable large-button grid overlay' described, but the broad problem space is well-served, leaving only a narrow wedge.SteadyMouse - Hand Tremor Mouse Accessibility Software ↗GitHub - LazoVelko/neverclick: Never use a mouse again. ↗
Willingness to pay exists (SteadyMouse 2 runs on a paid model after 20 years and still sells), but the buyer pool is small, often price-sensitive disability users, and free OS features plus free OSS tools like dwellpy compress pricing — a $10-30/year tool is plausible but not a big market.SteadyMouse - Purchase ↗dwellpy · PyPI ↗
Motor disabilities are permanent conditions, not a trend — the need persists indefinitely
Cross-application overlay + dwell detection is non-trivial on Windows (Neverclick needs to register itself as an accessibility tool in Program Files) and requires system-level input synthesis, on-screen grid rendering across all apps, and accessibility-API or CV-based target detection — achievable but multi-month engineering effort, not a weekend build.GitHub - LazoVelko/neverclick: Never use a mouse again. ↗
