In certain embodiments, a system for controlling a laser device comprises a laser device, a haptic sensation generator, a gesture detector, and a computer. The laser device generates a laser beam with a focal point to perform a procedure on a patient. The haptic sensation generator generates an acoustic field that projects a sensory pattern onto a user, where the sensory pattern operates as a user controller related to the procedure. The gesture detector detects a gesture of the user interacting with the user controller, and provides a description of the gesture. The computer: instructs the haptic sensation generator to generate the acoustic field that projects the sensory pattern operating as the user controller； receives the description of the gesture of the user interacting with the user controller； and provides instructions to perform an operation corresponding to the gesture.
