This is a very impressive overview of new user interface ideas. It's a fact that we need new userinterfaces for all kinds of use cases - and as it turns out there are unbelievable cool things going on in the UI research.

"Good user interfaces are crucial for good user experience. It doesn’t matter how good a technology is — if we, designers, don’t manage to make user interface as intuitive and attractive as possible, the technology will hardly reach a breakthrough. To gain the interest in a new product or technology, users need to understand its advantages or find themselves impressed or involved.

And here is where creative ideas and unusual interface approaches become important. Innovative doesn’t mean usable and usable hardly means innovative. As usual, it’s necessary to find an optimal trade-off. And some user interfaces manage to achieve just that."
