Naturally Parkview Towers' virtual window effect can only function properly when the player is within the PlayStation 4 Camera's range.
Which brings up an issue: What happens when a player leaves the camera's range?
Parkview Towers uses an elegant solution that seamlessly integrates this limitation into the game.
If the player (or the PS Move Motion Controller attached to his weapon) moves out of range of the camera, a Blast Shield will quickly descend from within the wall to cover the window.
The Blast Shield descends to cover the window
In other words, the graphics on your television monitor that depict the virtual world outside your window, which rely on accurate head tracking data to be rendered properly, are suddenly covered by a depiction of a 2D plane that is flush with the window/monitor, which does not rely on head tracking data.
With the Blast Shield down, the monitor can be viewed from any vantage point - even from far outside the PS4 Camera's range - while maintaining the integrity of the virtual world.
The Blast Shield has an integrated (virtual) video screen. The video screen can show a 'live shot' of the scene outside the window, so you can see what's going on out there even with the Blast Shield down.
