Scrolls

A Scroll is an object that functions as a collapsible, holographic tablet. It can be used as a phone, a portable computer, a camera and a streaming device as well as a gaming controller, among other functions.
  During combat it is able to gauge a user's Aura and depict it as a life bar, along with those of the user's teammates.
  The Scroll is clearly more advanced in some ways than contemporary handheld devices. Visibly, they are nothing more than a translucent, touch-sensitive panel between two solid end grips; the interlocking design of these grips allows the unit to be collapsible, much like a scroll of paper, hence the name.
  Each Scroll has a yellow, diamond-shaped button in its center when the device is in its closed state. The user presses this button to unlock the two grips and deploy the screen. This button also flashes when the Scroll gives an audible alert, such as when a new message has been received.
  Scrolls appear to come in two different sizes. Small Scrolls can deploy to be approximately the size of a smartphone, while large Scrolls can deploy to be the size of a medium-sized tablet. It appears that the size of a Scroll's screen is adjustable by how far apart the user pulls the grips. Scrolls can be opened horizontally or vertically, though it appears that the widely preferred orientation is horizontal for large Scrolls and vertical for small Scrolls. Scrolls are powered by Dust, and can be charged when their energy runs out.
  Usage Scrolls are shown to have a range of sensory and interfacing functions, such as relaying information from surveillance devices in real time and monitoring the Aura levels of multiple people at once. Several icons at the top right of the display hint at Internet-style browsing functions, such as Home, Search and Mail. There are also folder icons, indicating that the device can be used to store data.
  The 'mail' function has been shown to access voice messages as well as displaying short text-only messages, similar to the real-world SMS system. Scrolls also can function as keys.
