Abstract
According to one embodiment, an apparatus includes first and second liquid crystal lenses, a pair of temples, a sensor, and a driver. The first liquid crystal lens includes a first liquid crystal layer and a plurality of first control electrodes on the first liquid crystal layer. The sensor is provided on one of the pair of temples, and detects a contact position on a detector plane. The driver applies a plurality of voltage to the plurality of the first control electrodes. A focal length of the first liquid crystal lens is determined according to an amount of movement of the contact position when the contact position continuously moves along a longitudinal direction of the sensor. Each voltage value is determined according to the focal length of the first liquid crystal lens.
