Wow — this was very inspiring and a great collection of innovation that has started to change the world. And it will with 100% certainty.
Still let me comment on the title. I’m not counting beans or being nitty gritty — but “UI less” is massively misleading. The USER INTERFACE (UI) as the name says is the way a USER INTERFACES with something else. If we take that away it is not interfacing anymore.
CKH UI (Cutaneous, Kinesthetic and Haptic)
The next generation UI — even though you hate the term I guess — is a profound shift from today’s UI that involves screens, screen interfaces, mouse, keyboard it’s interface software with the CPU and a rather limited radius between USER INTERFACE components and CPU. Cutaneous interaction is the one where our skin detects and responds to change on its surface. The Kinesthetic learning is a style in which learning takes place by the people carrying out physical activities, rather than reading screen advice or manuals. And Haptic response mechanisms give us the much needed feedback on actions we attempt to do. On-Screen or laser keyboards are still not as comfortable than standard keyboards where the haptic feedback provides a better response. Now in many cases we can replace the haptic feedback with a visual feedback or a kinesthetic feedback. But somehow our brain acts fastest when we get a confirmation on our actions fast.
All new UI requirements
I trust we are both on the same page — what you showed us is amazing and most likely not only replaces some of the old interaction mechanisms but provides hundred times more opportunities to interface with things we can’t really interface well today. However Creating those UIs for those new types of interactions will require even more effort from UI designers to make it work the way a human want to interact with objects of any sort than today.
