Build a Custom CapsLock Indicator with AutoHotkey

CapsLock Indicator Design Ideas for Accessibility

1. Multiple sensory channels

• Visual: Clear on-screen icon with high-contrast colors (e.g., white text on dark background) and an accessible size. Use color plus shape or text so information isn’t conveyed by color alone.
• Auditory: Optional brief tones or speech feedback when CapsLock toggles; allow customization and mute.
• Haptic: For devices with vibration, provide a short, distinct vibration pattern when toggled.

2. Persistent and discoverable placement

• Place the indicator where users naturally look: near the text cursor, in the system tray/status bar, or as a small badge on the typing field. Allow users to pin or move it.

3. Clear states and affordances

• Show distinct states: On, Off, and Mixed (if applicable). Use concise labels like “CAPS ON” / “caps off” and an explicit icon (lock with “A”).
• Provide hover/tap text explaining state and how to change it.

4. Configurable visibility and behavior

• Let users choose: always visible, visible only when typing, or hidden unless toggled.
• Offer size, color, and opacity controls; keyboard shortcut to toggle visibility.
• Allow per-app rules (e.g., visible in password fields only).

5. High contrast and scalable UI

• Support WCAG contrast ratios (4.5:1 for normal text) and scalable fonts/icons for low-vision users. Ensure zooming/resizing preserves layout.

6. Keyboard and screen-reader friendliness

• Expose state via accessibility APIs (e.g., ARIA, native OS accessibility hooks) so screen readers announce changes.
• Ensure indicator is reachable via keyboard focus and has clear accessible name and role.

7. Minimal interference with typing flow

• Use subtle animations and avoid modal dialogs. Keep notifications short (<1.5s) or user-dismissable.

8. Context-aware behavior for password and secure fields

• In sensitive fields, offer an optional setting to always hide visual state but provide auditory/haptic feedback instead.

9. Localization and clarity

• Localize labels and use plain language. Avoid abbreviations unless common in locale.

10. Testing and personalization

• Provide presets for common needs (low vision, color-blind, no-sound). Include a quick accessibility testing mode so users can preview how indicators behave with screen readers, high contrast, and keyboard navigation.

If you want, I can produce example mockups (sizes, color hexes, and ARIA attributes) or a short spec for implementation in Windows, macOS, or a web app.
