Google Vision Glasses 6 Calibration Guide

Introduction

Google Vision Glasses 6 bring advanced augmented reality capabilities to everyday life, but the best experience comes when the device is finely tuned to your eye and environment. Calibration aligns the optical displays, sensor data, and gesture recognition so that virtual elements appear stable, sharp, and intuitively responsive. This guide walks you through the complete calibration process, from initial setup to fine‑tuning, ensuring that your glasses deliver accurate overlays and comfortable vision every time you use them.

Safety and System Prerequisites

Before starting any calibration, read the safety information below:

• Power: Ensure the glasses are fully charged or connected to a charger. Calibration uses sensor data that can be sensitive to sudden movements, so a stable power source avoids interruptions.
• Firmware: The glasses must run the latest firmware version. Calibration routines are tied to specific firmware releases; an older version may produce incorrect settings or skip critical steps.
• Lighting: Perform calibration in a well‑lit room with natural or balanced artificial light. Extreme brightness or darkness can affect the eye‑tracking sensors.
• Environment: Keep the calibration area free of strong reflections, moving objects, and obstacles that could interfere with the sensors.

Connecting to the Companion App

The companion app on your smartphone or tablet serves as the interface for initiating and monitoring calibration. Follow these steps to establish a stable connection:

1. Install the latest Google Vision Glasses Companion app from the Play Store or App Store.
2. Open the app and select Add New Device.
3. The app will search for nearby Bluetooth Low Energy (BLE) devices.
4. Once your glasses appear, tap Pair.
5. If prompted, enter the on‑screen code displayed on the glasses.
6. After pairing, tap Device Settings and confirm that the device status reads Ready.

A successful pairing will display a green check mark next to the device name. If the pairing fails, restart the glasses, clear Bluetooth cache, and try again.

Checking for Firmware Updates

Calibration instructions depend on the current firmware. To verify you have the latest version:

• In the companion app, go to Device Settings > Firmware.
• If an update is available, tap Download & Install.
• Wait for the process to complete; the glasses will reboot automatically.
• Re‑open the app and confirm the firmware version matches the recommended one for your region.

Firmware updates often include performance improvements for sensor fusion and eye‑tracking accuracy, which are critical for reliable calibration.

Powering On and Entering Calibration Mode

With the glasses ready, you can launch calibration from the device itself.

1. Locate the Power button on the right temple. Press and hold for two seconds until the LED flashes blue.
2. The glasses will boot and display a Calibration Prompt on the lenses.
3. Follow the on‑screen instructions: a series of squares and dots will appear to guide eye movement.
4. Swipe the prompt to the Calibration Menu.
5. Select Run Calibration.

During this process, the glasses will record the relative positions of your eyes, the optical alignment, and the depth perception baseline. The companion app will also log sensor data for troubleshooting if needed.

Step 1 – Aligning the Calibration Target

A central part of the calibration sequence is the Calibration Target, a series of grid points that the glasses track as you look around.

1. Position yourself at a distance of 60 cm (24 in) from the target.
2. Hold your head steady and allow the glasses to detect your eye position automatically.
3. The app will present a grid of 9 points in a 3×3 pattern.
4. Blink naturally and move your gaze from one point to the next as the prompts appear.
5. When the prompt flickers green, tap the screen or press the shutter button to lock the point.

Repeat the sequence until all nine points are marked. If the glasses report an error at any point, move slightly forward or backward and try again.

Step 2 – Adjusting Lens Focus

The Vision Glasses 6 use adjustable focus to accommodate various vision corrections. Calibration fine‑tunes this mechanism.

1. After completing the grid, the app will display a Focus Test screen.
2. Read the on‑screen text while the glasses display a blurred and a sharp image side by side.
3. Adjust the focus using the dedicated Focus Dial on the right temple.
4. Turn the dial clockwise to increase focus (tighter blur) or counter‑clockwise to reduce focus.
5. The display will update in real time; stop when the two images appear equally sharp.
6. Confirm by pressing the Lock Focus button.

If you are wearing prescription glasses, calibrate after removing them to allow the lenses to settle fully. Then repeat the focus adjustment with your prescription glasses on to see if any additional tweaks are necessary.

Step 3 – Calibrating Depth Perception

Depth perception, or the ability to gauge distance, is crucial for accurate overlay placement. The glasses use inertial sensors and camera input to estimate depth.

1. The companion app will display a Depth Grid of circles at varying distances (10 cm, 30 cm, 60 cm).
2. Look at each circle as it is highlighted and tap the screen to confirm.
3. The glasses will adjust the depth baseline based on your response.
4. Once the grid is complete, the app will show a Depth Confirmation screen with a slider.
5. Slide the bar until the virtual objects in the view appear at the expected distances.
6. Tap Apply Depth Settings.

Step 4 – Fine‑Tuning Eye‑Tracking

Accurate eye‑tracking allows the glasses to respond to subtle gaze shifts. Calibration refines the tracking algorithm.

1. The app presents a Eye‑Tracking Demo: a set of shapes will change color as you move your eyes.
2. Follow the shapes as they appear, keeping your head still.
3. Adjust the Tracking Sensitivity slider if the shapes respond too quickly or slowly.
4. Confirm by clicking Save Tracking.

If you notice jitter or lag, return to the previous steps and re‑run the calibration, ensuring the environment remains consistent.

Step 5 – Validating the Calibration

After completing all steps, you must confirm that the glasses work as intended.

1. Exit the calibration menu and return to the main dashboard.
2. Open an AR application (e.g., Google Lens AR) and observe virtual overlays.
3. Test the following scenarios:
   • Text Overlay: Ensure the text is crisp and correctly positioned relative to real objects.
   • Object Recognition: Verify that recognized items remain in place when you move your head.
   • Gesture Control: Perform a swipe or tap gesture and confirm the correct response.
4. If any element appears misaligned, repeat the calibration steps.

Successful validation will leave the display stable across varied lighting and movement.

Saving the Calibration Profile

Once validated, the glasses will prompt you to Save Profile. This stores all calibration data locally and in the cloud for quick restoration.

• Tap Save Profile.
• Give the profile a descriptive name (e.g., Home Calibration).
• The app will sync the profile to your Google account, enabling automatic restoration on new devices or after a factory reset.

Advanced Manual Calibration

For users who require precise control (e.g., medical professionals, developers), the companion app offers manual overrides.

• Open Advanced Settings in the app.
• Use the Manual Adjustment sliders for lens alignment, focus, depth, and eye‑tracking.
• Each slider provides a numeric value that corresponds to sensor units.
• Apply changes gradually; test after each adjustment.

Note: Manual calibration bypasses safety checks. Use only if you understand the underlying parameters and the risks involved.

Troubleshooting Common Issues

If problems persist, contact Google support or visit a certified service center.

Frequently Asked Questions

Q: How often should I recalibrate my glasses?
A: Ideally every 6 months, or whenever you notice drift in overlays, changes in prescription glasses, or after a significant shift in ambient lighting conditions.

Q: Can I calibrate with prescription glasses on?
A: Yes, but calibrate once with your glasses removed to set the baseline focus, then fine‑tune with them on to account for your prescription.

Q: Does calibration affect battery life?
A: No. The calibration process consumes a negligible amount of power and does not impact long‑term battery performance.

Q: What happens if I forget to save the profile?
A: The glasses revert to the last saved profile on boot. If none exists, they will revert to factory settings.
