Nokia and Microsoft are trying something different. It’s called Nokia Music Mix Party, and revolves around Microsoft’s Xbox 360 console. The idea: people visit the Mix Party website using the console’s Internet Explorer browser, pick three artists and start a “party playlist”, with guests able to then scan a QR code to vote on what they want to hear next – whether they have an iPhone, Android or Windows Phone. QR codes and house parties: together at last! And while this has the air of an (admittedly fun) techsperiment, Microsoft says it fits into a wider trend called the “companion web” – “The web today is built for one device at a time, but soon – our favorite websites will be smart enough to know we have these devices around us, and will begin to offer opportunities that bring our different ’screens’ together as a seamless connected experience,” blogs Microsoft\’s Roger Capriotti.
