    Abstract: A system and method include generating environment data from skylight sensor data. The environment data includes a value of a geospatially dependent parameter associated with light received from a predetermined celestial light source. At least two of a compass direction of the predetermined celestial light source when the skylight sensor data was received, a time at which the skylight sensor data was received, or a geospatial coordinate at which the skylight sensor data was collected are received. At least one of the compass direction of the predetermined celestial light source when the skylight sensor data was received, the time at which the skylight sensor data was received, or the geospatial coordinate at which the skylight sensor data was collected is determined, at least in part, from the environment data.

    Abstract: An electronic device, method, and computer readable medium for augmented reality system is provided. The electronic device includes a light source that emits a light towards an eye of a user of the device, an adjustable lens having an adjustable focal point, a light sensor, configured to detect a reflected light that is reflected from the eye of the user, a processor, and a display screen. The processor determines a first distance corresponding to a focal point of the eye based on one or more positions of the reflected light, and adjusts the focal point of the lens unit based on the focal point of the eye. The display screen is configured to present an image of the object at a second distance based on the focal point of the lens unit to create a perception for the user that the image is placed at the first distance.
