The keyword is 'interactive'. In our view, the meaning of the word interactive is: making the user 'experience' a device, 'live' it, enjoy it, utilize it, learn through it. Or, in few words, interact with it. In our opinion interaction design should make devices usable, useful and fun, with a double need: to focus on users and their experience and necessities, and to enhance devices distinctive features. So, we think it is necessary always to centre on the two components of the interaction: user and device.
Communication, education and learning, entertainment, fun: in every time, all these activities take advantage of the available technology. And the future (actually, already the present) of the technology will be about flexibility and portability:
Design user interfaces, interactive multimedia contents and app, but why? Because we believe that a good designed application, or web site, or user interface, can really make users' life better. Games, educational application, informative contents: everything could be funnier, more useful, more satisfying if well designed. And so, let's try to do it!
