You can use head tracking on your iPhone through the Switch Control feature, which leverages the TrueDepth camera (available on iPhones with Face ID). This allows you to control on-screen actions by moving your head.
Enabling and Configuring Head Tracking
Here's a step-by-step guide to turning on and customizing head tracking:
- Open Settings: Go to the "Settings" app on your iPhone.
- Navigate to Accessibility: Scroll down and tap on "Accessibility."
- Select Switch Control: Find and select "Switch Control" within the Accessibility menu.
- Enable Head Tracking: Tap the "Head Tracking" toggle to turn it on.
Customizing Head Tracking
Once Head Tracking is enabled, you can customize several settings to tailor the experience to your needs:
- Actions: Assign specific actions to different head movements (e.g., tilting your head left might select an item).
- Pointer Speed: Adjust the sensitivity of the cursor movement based on your head movements. A higher speed makes the cursor move faster with smaller head movements.
- Tracking Mode: Choose how the head tracking interprets your movements. Common options might include relative or absolute positioning.
- Switch Control Settings: Fine-tune other Switch Control settings to work in conjunction with head tracking for a more comprehensive control experience. This includes things like auto-scanning and dwell time.
Considerations
- TrueDepth Camera Required: Head Tracking relies on the TrueDepth camera system, so it's only available on iPhones with Face ID (e.g., iPhone X and later).
- Accessibility Feature: Keep in mind that Head Tracking is primarily an accessibility feature designed to assist users with motor impairments.
- Battery Consumption: Using the TrueDepth camera continuously can impact battery life.
