The main challenge in implementing the design was the short throw distance of the 7'2" x 9'5" oval, rear-projected screen. The Discovery Wall is the main attraction with a dynamic digital display of donor names on a large oval screen, accompanied by three interactive round touch screens.

With a combination of both static and digtial displays, the space was intended to create a one of a kind user experience, while showcasing the many donors who have made the hospital a reality. The objective of the project was to create a fun and uplifting "Lobby Experience" for patients, staff and visitors of the University of Minnesota Amplatz Children's Hospital. The hanging banners have been delighting audiences since they were first launched at the 2010 Season Opener. All Image processing done in the IA-200 enabled the economic selection of projectors with the highest light output. IA-200’s distortion-free Scaling and Geometric Correction enable the precise alignment and blending of all 4 images with networked precision control. The top and bottom halves of the banners are seamlessly edge blended to provide a vertically oriented dynamic banner with transparency.

In addition, the unconventional shape and size of the banners compounded with the requirement of illuminating them with pinpoint accuracy from projectors mounted off-axis at a distance of 30 meters, presented a major challenge in signal processing and control.Įpic’s solution was to use two stacked 4:3 projectors for each half of a hanging banner, each with an IA-200 Geometry Correcting and Edge Blending Scaler. One major challenge was to ensure the banners would be able to capture enough light for an outstanding projection effect, yet simultaneously sufficiently transparent to provide the audience with a view of the ice as players entered the arena.
