|Science & Tech Spotlight: Extended Reality Technologies|
Extended reality—which includes augmented, mixed, and virtual reality—combines the real and digital worlds to create new kinds of interactivity and perception. These technologies provide new ways to train, educate, entertain, and collaborate. For example, mixed reality technology can help train surgeons by allowing them to interact with 3D images of organs as opposed to the 2D images available on flat screens. But extended reality could also make more data vulnerable and create opportunities for online harassment. We discuss the types of technologies, the challenges they face, and more.
