Interactive transparent displays like the Planar OLED Display are currently mainly used to market products but there is potential for them to be useful in meetings.
As the display can be connected to a computer, participants could actively collaborate using the display during a meeting instead of simply sitting around a table.
While the extent of the user’s ability to control objects/application on the display would depend on the technical specification of the display chosen, it would be ergonomically better than having the display flat on a table.
