A measurement system consists of a head mounted device (HMD) 1210 with one or more imaging sensors 1212, 1214 that capture an image of at least one eye of a user wearing the HMD. A processing unit 1220 calculates a position, relative to the face of the user, of the centre at least one eye of the user based upon the captured image and a predetermined position of the one or more imaging sensors. Different users may have different vision requirements that may require an HMD to be modified for each user’s vision requirements. For example, an HMD may need to be calibrated for a user’s interpupillary distance (IPD) so that images, or viewpoints displayed in such images, may be appropriately aligned for each eye.
