Sub-heading: Calibration - The Crucial Step!
Once you enable Eye Tracking, your iPad will guide you through a calibration process. This is absolutely essential for accurate eye tracking.
- Your iPad will display a series of colored dots that appear in different locations around the screen.
- Follow these dots with your eyes. Try to keep your head as still as possible and only move your eyes.
- The goal is to gaze steadily at each dot as it appears. The system uses this to learn your eye movements and establish a baseline for tracking.
- Important Tips for Calibration:
- Position: Place your iPad on a stable surface about 1.5 feet (around 45 cm) away from your face.
- Lighting: Ensure you are in a well-lit area, but avoid direct glare on the screen or your face.
- Minimize Movement: Try to minimize head movements during calibration.
- Avoid Blinking (if possible): While some blinking is natural, try to keep it to a minimum during the calibration points.
After successful calibration, an onscreen pointer will appear, following your eye movements!
Step 3: Using and Customizing Built-in Eye Tracking
Now that eye tracking is active, let's explore how to use it and fine-tune its settings to your preference.
Sub-heading: Basic Interaction with Eye Tracking
- Moving the Pointer: Simply move your eyes across the screen, and the onscreen pointer will follow.
- Selecting Items (Dwell Control): To "tap" or select an item, hold your gaze steady on it. An outline will appear around the item, and a "dwell pointer" (a circle that fills up) will indicate the timer. Once the circle is full, the item is selected.
- AssistiveTouch Integration: When Eye Tracking is on, the AssistiveTouch menu automatically activates. This provides a customizable floating menu that offers quick access to various actions and gestures, which you can select with your eyes.
Sub-heading: Adjusting Eye Tracking Settings
Go back to Settings > Accessibility > Eye Tracking to adjust the following:
- Smoothing:
- Increase this value to make the pointer movement smoother. This can be helpful if your eye movements are a bit shaky.
- Decrease this value to make the pointer more responsive to subtle eye movements.
- Snap to Item:
- When enabled, the Eye Tracking pointer will automatically move to the item on the screen that's closest to where you're looking. This can significantly improve accuracy and ease of use.
