> There is basically zero evidence that this device provides better quality of life than the systems that already existed. IMO it is less about which purpose this specific device is used for, and more about what this breakthrough has the potential to enable us to do in the future, using this tech as the basis to build on top of (assuming it is proven a success and all the kinks are worked out). If there was a standardized "smart hat" that I could put on my head that would allow me to control my AR glasses in an efficient way, that would be crazy. Because right now, that's one specific concern regarding AR usability, since current solutions with buttons and touch surfaces and voice controls and making hand gestures are awkwardly inconvenient and feel clunky. UI/UX paradigm for certain consumer device categories completely shifts. A lot of accessibility problems get resolved. Hardware itself on a lot of consumer devices can become much simpler and more robust, since there is no need for much hand-driven interaction. And that's just a singular the most obvious example I could've thought of. There are plenty of potential amazing things that could be enabled by this tech, even if the specific use case for it that was presented in the article might not "provide better quality of life".
