Interpupillary distance (IPD) is the distance between the centers of the pupils of the two eyes. This distance varies from person to person and is an important factor to consider when using virtual reality (VR) headsets.
In VR, the IPD is used to ensure that the images presented to each eye are aligned correctly, which is essential for a comfortable and immersive experience. If the IPD is not properly calibrated, it can cause eye strain, headaches, and other discomforts.
When selecting a VR headset, it’s important to choose one with an adjustable IPD, as this will allow you to fine-tune the settings to match your own IPD. Some VR headsets have a manual IPD adjustment, while others have an automatic adjustment feature. In either case, it’s important to follow the manufacturer’s instructions for proper calibration.
