Just think for a moment on all the unique interfaces we humans encounter with our tools on a daily basis*. No interior in our cars look the same, coffee machines have varying functionalities, every vacuum has its buttons placed differently, all our digital interfaces (smartphones, smart home control panels, digital oscilloscopes, synthesizers etc.), even simple remote controls etc. Some of these interfaces are just some designers choice on top of an already standardized digital protocol (CAN bus, Bluetooth) - so this thing takes the hard way and needs to adapt to all those interfaces in order to be more useful than "can follow you around"?
Honestly, I think that would be quite an achievement and could be great for something like elderly care. Although this thing needs to be able to do useful tactile tasks first, like putting a thread through a pinhole, or cutting your vegetables in cubes of equal size. I'd look forward to seeing a demo!
*: How many things do you personally encounter with the exact same interface? iPhones yes-ish (apps can be renamed and shuffled around, the control center can be customized etc.), but not even QWERTY keyboards. I think we humans constantly strive for some form of individuality.
