Patent attributes
A system may include haptic output devices such as ultrasonic haptic output components that generate ultrasonic sound waves. The ultrasonic sound waves may be directed towards a user to provide haptic output. The haptic output devices may be used in a system that includes one or more electronic devices. Control circuitry may control the haptic output devices based on sensor data indicating where the user is located and/or based on what is being displayed for a user on a display. Ultrasonic haptic output may be used to simulate contact with a virtual object, to simulate rain, to simulate a breeze, and/or to simulate other sensations in a mixed reality or virtual reality environment. The ultrasonic haptic output components may be stand-alone devices or may be mounted in a head-mounted display, a gaming base station, a handheld controller, a finger-mounted device, or other electronic equipment.
