An app launcher that did essentially that (start to type the name) is easy enough to build that the problem much lie elsewhere. Possibly with the interface itse

An app launcher that did essentially that (start to type the name) is easy enough to build that the problem much lie elsewhere. Possibly with the interface itself (mobile devices inheriting legacy web ux & ui.) I would suggest the essential difference may be found along an axis of user input that has data entry at one end and pure selection on the the other. I'd further suggest that as this technology evolves the emphasis shifts from data entry to selection and interaction with technology becomes less about inputting data and more about making choices. What data is needed is grabbed from your device's sensors; you don't actually need to enter it. Ultimately what we're trying to build is a device that knows what you want (before you do!) and serves it up to you with the greatest efficiency.
