The Future of Human Computer Interfaces = No Keyboard
John Underkoffler is the creator of the now famous Minority Report gestural interface. The future of human computer interface is no keyboard, it’s you. In the very near future navigation happens in 3D. The system is about manipulation and navigation in the virtual space while interacting with real world objects (like your hands).
Among the spectacular-ness of gestural is a way of navigating data (as seen in Minority Report). Here you can take tabular data and apply it to geo-spacial information so the data can be understood and made meaningful. The collaborative design work demonstrated is also amazing.
To paraphrase Underkoffler regarding his inspiration: We create and our technology is a combination of design and efficacy that allows us to do that.
