Scroll

The scroll is an object that appears to function as a futuristic hologram tablet. It is able to gauge one's Aura and depict it as a lifebar, along with those of the user's teammates, as well as stream video from cameras.

Appearances
A scroll was first seen in Ruby Rose, held by Glynda Goodwitch as she lectured Ruby Rose on how reckless she was. When Ozpin entered the room, Glynda used her scroll to display a recorded video of Ruby's fight with Roman's henchmen. Later, Glynda was seen holding one in the episodes The First Step and The Emerald Forest, Pt.2. In the latter episode, she was seen using it to view videos of various students in the forest, and Ozpin was seen using a scroll to watch a live video of Ruby and Weiss. At the end of The Badge and the Burden Part 2, when Weiss found Ruby asleep, a scroll is visible on Ruby's bed. The name of this device was finally given in the episode Jaunedice, shortly before Jaune is seen in possession of a small scroll displaying his and his teammates' Aura as health meters.

Functions and Capabilities
The Scroll is clearly far more advanced in some ways than contemporary real-life hand-held devices. As well as being visually nothing more than clear plastic (probaby containing liquid crystal of some form) between two plastic end-grips, they are shown with a range of sensory and external interace functions such as playing real-time up-links from surveillance devices and medical/health scanning capabilities for multiple persons at one time. All controls of the Scroll are by touch-screen; there are no visible buttons or switches on the solid end-grips

We have so far seen two sizes of Scroll, the teachers at Beacon Academy have large units whose screen size is about similar to that of a piece of standard letter paper. The students are issued smaller terminals about the size of a small tablet computer.

The display of Jaune Arc's scroll has several icons displayed at the top of the screen hinting at standard web browser-type functions such as 'go to home-page' and 'search'. There are also folder icons indicating that the device can be used to store data and possibly documents such as school assignments.

It is not clear if the Beacon Academy Scrolls are stand-alone devices or whether they are mobile terminals for a larger, fixed computer system that serves all the school faculty and students.

Trivia

 * Ruby mentions on her Twitter account that she has to get her own scroll, now that she's been moved ahead two years. This implies that scrolls are supplied by Beacon Academy, and that they are not needed at Signal Academy.
