Time for some truly revolutionary GUIs?
Mice, touch, start menus ... how traditional ... how old-fashioned .... how computer-centric.
And by computer centric, I mean just that: having the computer: be it a PC (a "proper" computer) a phone or a tablet, at the fore of the operations.
Instead, how about putting the person or the user in the spotlight? So instead of us having to press the buttons and direct the machine to perform what we want it to, shouldn't IT be asking US what WE want. So instead of having a menu or GUI that says: these are your options: pick one, the interface asks one simple question:
What do you want to do?
So the user can write, speak or draw their request: I want to write a letter, I want to watch a film, I want to continue reading my book, I want a command line, I want to search the internet, I want to know what this (holds summat up to the camera) thing is for ...
After that, it goes away and works out how to fulfill our requests. Obviously if it is unable to do so, it should respond in a calm, cool and not-quite-remote voice to the effect "I'm sorry Dave, I can't do that" Though I suppose we'd all have to change our names (or at least our accounts) to make this happen. A small price.
