Abstract:
A display apparatus includes a display, a sensor, and at least one processor. The display is configured to display an image. The sensor is configured to sense a touch input on a touch surface, the touch input being caused by at least one touch unit among a plurality of touch units mounted to a user and corresponding to a plurality of preset operations to be performed in the display apparatus. The at least one processor is configured to determine the at least touch unit that causes the touch input sensed by the sensor among the plurality of touch units, and execute an operation which corresponds to the determined at least one touch unit among the plurality of preset operations with respect to the touch input.
Abstract:
A photoacoustic probe module includes an optical system configured to guide a laser beam generated by a laser source such that the laser beam arrives at an object at a target incidence angle and penetrates the object to a target internal depth, and a photoacoustic probe configured to receive acoustic waves emitted from the target depth by the laser beam.
