Natural user interfaces are all about alignment
August de los Reyes, design director of Artefact Group (formerly of Microsoft Surface), was one of the speakers at MIX11, a Microsoft organised gathering of developers, designers, UX experts and business professionals “creating the most innovative and profitable consumer sites on the web”.
In his excellent talk August wowed the audience with his talk on 21st Century Design and how the future thinking of design is changing.
He advocates that natural user interfaces are all about alignment (rather than usability), and argues that we rethink the design process annd focus on motivation, needs, positive emotion, learnability, adaptability, and revolutionary changes. This is in contrast to a [more conventional] user-centric design which puts faith in the users (who often donâ€™t know what, why, and how they like something), and incremental design evolution.
