In the concept I tried to focus on two main aspects. On the one hand side I wanted it to show such a full-functional experiece, being similar to the real play store on Android phones. On the other hand side I also tried to find a way the store could be used as well without the need of any voice-commands, but only with the touchpad.
To achieve the latter one, scrolling and swiping plays a very important role. Scrolling upon the pages bottom or top can set off full interactions, as for example to install an application or to navigate back (much like the ‘swipe down to refresh’ feature found in many mobile applications).
Further more there is also a new way to point the user to voice commands incidentally: The commands are often part of headlines. So the real title is formatted differently than the thing you might say.
I think all in all this could work really well. Especially the fact that you don’t need voice commands is something I’d really like about it. You just cannot always speak freely, sometimes it’s too noisy and sometimes you just don’t want everybody to know what you’re doing right now.
