Powerwall

Currently, the highest resolution display in the world is the Reality Deck,[3] running at 1.5 billion pixels, powered by a cluster of 18 nodes.

[6] Finally, software techniques such as modifying the window management interface or providing a lens for selecting small targets has been found to speed up interaction.

[7] In the field of medical visualisation, Powerwall displays have been used to render high-resolution, digitally scanned histology slides,[8][9] where the high pixel count increases the volume of data that is rendered at any one time, and the context offered by the size of the display provides a spatial reference, aiding navigation through the visualization.

The same principal can also be said for geographical data such as maps, where it has been found that the large display real estate increases performance for searching and route-tracing.

A recent study found that during a collaborative sensemaking session in front of a multi-touch Powerwal display, the ability to physically navigate allowed users to fluidly shift between shared and personal spaces.
