PTPT and if you say it just right it comes out petit petit (petit the French word for small). But the Petit Petit touch screen user interface out of Germany will have no small impact on computing. This blog is not at all about User Experience because there are much better sources for that type of content. But having said that, application architecture fails if it does not incorporate an effective user experience. So having seen lots of bad and not-so-good user interfaces, when a brilliantly intuitive user interface concept comes along, I have to evangelize about it. Simply put, Petit Petit brakes ground by categorizing ALL of your digital information (pictures, music, documents, email, etc.) into those four dimensions (people, things, places and time) and allows you to manage that data based on the associations between the dimensions. As a very brief example, to find that email from Johnny from last November, you drag the contact of Johnny over to email, then up to the timeline near Nov and up pops your filtered list of emails around that timeframe. Even discounting the touch aspects of this project, the realization that data can be organized in such a clear, concise manner could lead to effective interfaces for the other projects that I am working on.
