Abstract

A portable virtual, augmented, or mixed reality device, including: a mount intended to be worn on a user's head; a display screen attached to the mount and intended to be arranged in front of one of the user's eyes; a plurality of ultrasound transducers attached to the mount; and a control circuit configured to control the display screen to display images, and the ultrasound transducers to generate, in air, at a distance from the mount, a pressure distribution detectable by the user's hand to obtain a haptic effect.

Description

[0001] This application claims the benefit of priority from French Patent Application No. 19 / 01269, the content of which is hereby incorporated by reference in its entirety to the fullest extent permitted by law. technical field [0002] This disclosure relates to virtual, augmented, or mixed reality devices. Background technique [0003] Portable virtual, augmented or mixed reality display devices of the glasses or mask type have been provided which include a base intended to be worn on the user's head and a display screen attached to the base, the display screen being intended to be placed on at least one of the user's In front of the eyes, usually a few centimeters away from the user's eyes. The screen enables the user to display visual images. The screen may be opaque. From the user's point of view, the image displayed on the screen replaces the real scene in the user's field of vision, so it is called a virtual reality display device. As a variant, the screen may be ...
