A visible caret or pointer state that helps users track input focus or text insertion position, essential for low-vision and cognitive accessibility.
An active cursor indicator is a visual element that shows users where their input focus is located, particularly in text fields and other input areas. This is crucial for users with visual impairments, cognitive disabilities, or those using assistive technologies who need clear feedback about their current position.
The indicator typically appears as a blinking cursor, caret, or highlight that moves as users type or navigate through text. It should be clearly visible against all background colors and provide sufficient contrast to be easily seen by users with low vision.
Beyond basic visibility, effective cursor indicators should be appropriately sized, positioned correctly, and not interfere with the content being entered. They should also work consistently across different input types and devices.
Creating accessible cursor indicators requires attention to visual design and technical implementation:
Visibility Requirements: Ensure the cursor is visible against all possible background colors and themes. Use high contrast colors and consider providing customizable cursor appearance options.
Size and Shape: Make the cursor appropriately sized for the input field and content type. Consider that users with low vision may need larger or more prominent indicators.
Positioning: Ensure the cursor appears in the correct location relative to text and doesn't interfere with the content being entered.
Blinking Behavior: Use appropriate blinking rates that are noticeable but not distracting. Avoid extremely fast blinking that can trigger seizures in sensitive users.
Customization: Allow users to customize cursor appearance, including color, size, and blinking behavior when possible.
Cross-Platform Consistency: Ensure cursor behavior is consistent across different devices, browsers, and input methods.
Accessibility Testing: Test cursor visibility with users who have various visual impairments to ensure the indicators meet real-world needs.

Single‑letter keyboard shortcuts that must be remappable, turned off, or only active on focus to prevent accidental activation.
The contrast ratio between foreground and background colors. WCAG requires 4.5:1 for body text and 3:1 for large text, icons, and UI.
A range of conditions where certain colors are harder to distinguish. Designs must not rely on color alone to convey information.
Numeric ratio expressing luminance difference between two colors. Common thresholds: 4.5:1 for normal text, 3:1 for large text or UI.
