Abstract: A processor signals a display to show a target. Optics is positioned in an optical path taken by the target, as shown by the display, from the display to the eye of a user. The optics is configured to change accommodation by the eye and has adjustable focal length that enables the user to see the target with changing acuity. The processor then obtains an indication that the eye of the user is focused on the target. In response, the processor signals an alignment mechanism to align a sensor in the device to the eye of the user. After signaling the alignment mechanism to align the sensor to the eye of the user, the processor obtains sensor data, produced by the sensor, which measures a property of the eye. Other aspects are also described and claimed.
