Then, measure the distance of the dashes at the outside, and the dashes at the inside. Put a piece of paper in the middle of the lenses and draw dashes at the edges of the lenses as shown above. If you want to stop without making a change, look all the way down and wait.Īlternatively, you can measure the lens separation with this simple trick: This will bring you out of the calibration mode. When finished, wait for 5 seconds without moving. This is the distance at which you can gaze into the distance with relaxed eyes. Try moving the circles away from each other without putting a strain on your eyes. Move your head up and down to change the distance between the image pair. The lens separation value is printed in millimeters. The calibration screen displays concentric circles that should converge into one when adjusted correctly. If your viewer has lenses with adjustable IPD (interpupillary distance), adjust this distance first before adjusting the lens separation parameter. Use the vertical guide lines for precise positioning. Put your phone into the viewer while making sure the screen is centered in the middle of the viewer. It will instead adopt all viewer parameters such that other VR apps (based on Google Cardboard) will display a correct view.Ĭhoose Lens Separation from the list to set the distance between the lenses of the viewer.ĬAUTION: This is not the distance between your eyes! The app does not have the permission to change screen size at the system level. Pressing once more changes the format to the 'Credit-card', in case a ruler is difficult to get.Ĭhoose 'Save' to store the changed size or 'Cancel' to go back without a change. You can change the ruler format from centimeters 'CM' to inches 'INCH' by pressing once on the 'CM'. You can scale the ruler image with your finger or use the arrows. Looking from the side can give wrong results as there is quite some gap between the ruler and the screen image. Put a real ruler on the ruler image and change the screen size until the two exactly match.ĭon't forget to reposition your head such that you compare the rulers exactly from the top. The calibration screen displays a ruler image and buttons for making changes. Therefore, make sure the screen size is correctly set. Unfortunately, too many phones (even high-end ones) report a value that is not correct or not precise enough. To correctly render a VR image pair, the app has to know the exact screen size. The viewer settings menu allows the user to correct or personalize viewer parameters. Sites in VR - Viewer Settings Sites in VR Viewer Settings
