With the advent of virtual reality (VR) headsets like the Meta Quest 3 and Vision Pro, people are starting to worry about their long-term use** with cameras and screens"The digital world"What are the implications. In response, researchers at Stanford University's Virtual Human Interaction Lab (VHIL) conducted a study calling on industry and academia to be cautious about this emerging technology.
According to IT House, unlike optical headsets such as HoloLens and Magic Leap, which project virtual elements directly onto the glasses, the Quest 3 and Vision Pro use a tool called"Perspective"(Passthrough) technology, which captures the real-world environment through the camera and converts it into a digital** image and projects it onto an opaque display, and then overlays virtual elements to achieve a mixed reality (MR) experience.
Although perspective technology solves the shortcomings of optical headsets such as narrow field of view, there are also shortcomings that cannot be ignored: the world has become a ** stream, losing many colors, details and depth of field.
VHIL's researchers are concerned that with technological advancements and abundance of content, people may wear such headsets for long periods of time, immersed"The digital world", which can lead to visual sequelae, distance judgment errors, simulator vertigo, and more"Social absence"and other negative effects.
The study notes that there are no direct studies on the effects of long-term use of fluoroscopy**, especially in children. While the researchers recommend guidelines for limiting the amount of time they can use, they admit that such restrictions may have little effect, given the addiction to smartphones that have become ubiquitous.
In addition, perspective technology can also have a negative impact on social behavior. Researchers believe that interacting with people through perspective** is not a substitute for face-to-face communication and may lead to a sense of social distancing.
While the Apple Vision Pro offers the best perspective image quality to date, it's still far from perfect. Nilay Patel, editor-in-chief of The Verge, even believes that perspective can never replace natural vision, and that there may be bottlenecks in the development of the technology. He also criticized the Eyesight feature, which displays the user's eyes on an external display, hindering real eye contact with the real world.
However, VHIL researchers also point out that these shortcomings may be gradually overcome or reduced as technology advances.
