With a new PlayStation app, Sony plans to extend the PlayStation 4 console experience to a second-screen. Announced for iOS and Android devices, the app will allow players to enhance their gaming experience by accessing information – such as maps for the PS4 title being played – as well as make purchases for their console on the go and “remotely watch other gamers playing on their devices.”
Now, Sony has gone on record about their second screen initiative, indicating that
A new application from SCE called ‘PlayStation App’ will enable iPhone-, iPad-, and Android-based smartphones and tablets to become second screens. Once installed on these devices, users can, for example, see maps on their second screens when playing an adventure game, purchase PS4 games while away from home and download it directly to the console at home, or remotely watch other gamers playing on their devices.
Specific examples and availability details are not yet available. Sony will presumably have more to say about the second screen functionality in key PS4 titles as the console approaches its late 2013 launch.
Anyway, it’ll be interesting to see and hear more about the PS4 and its feature set as the hype train really starts rolling.
