Hyperwall and Mobile Technology

The goal of this project is to explore different configurations of multi-screen displays and interaction mechanisms. These are known as hyperwalls, in which multi-screens or projected images are aligned to produce one large display, that can be dyamically partitioned as needed and driven consistently by one or more computers. As processing units, LCD screens and pico projectors improve in price, resolution and power usage,  a variety of high resolution multi-screen EOC and ICP configurations could greatly increase the  amount of information that can be effectively used by one or more responders and commanders - including multi-layer Common Operating Picture maps, augmented with additional information generated by the Semantic Geotagging project. With the advent of browser based applications and maps, Internet-based and local server based maps become much more accesible and useful.

We are currently engaged in several experiments to assess cost, performance, usability, interaction style and energy use:

  • A small four screen hyperwall, with all displays driven by a single MAC Mini; interaction is through a single mouse. This is a candidate system for installing in the Next Generation EOC trailers, running on a solar powered 12 volt battery system.
  • A large eight- to ten-screen display, driven by one or two PCs, each with two four-ported graphics cards. The multi-screen image is genererated by a specialized HTTP proxy, which uses injected Javascript  to allow multiple cursors to be driven by multiple people using a variety of devices, such as mobile phones or tablets. This proxy allows multiple hyperwalls in multiple locations to share the same views including highlights and icons, potentially enhancing coordination and collaboration.

This project is supported in part by NASA DART.

Two Android smart phones each acting as both interaction device and
communication device. The green phone screen is driving the green
EMS icon on the screen, while the blue phone is driving a blue icon. One
possible use is to click on an icon and immediately have the phone call the
commander or responder at that location
