Displaying part for Multitouch sperical surface
Bright high-resolution back projection system for the domed screen of multitouch interactive terrestrial sphere (Globe/Globus/Глобус).
Existing technologies were adapted for this device to achieve exceptionally low construction depth.
A pixel-accurate and globally homogenous image appears on the lens surface; the individual images from the projector are implemented with a total resolution of minimum 1050×1050 pixels.

| • The domed screen surface possesses visual features in order to allow comfortable operation; this means that the operation supports both a visual and a sensory experience.
• It is to ensure an even image, independent of where viewers are positioned. • 100 Cm High contrast domed screen • Due to the large construction, is ensure sufficient warp resistance of the domed screen (spherical surface). |
 Domed screen |
| • The aim was to achieve the best possible presentation of the contents, e.g. films and pictures, for which a resolution of minimum 1050 x1050 pixels is realized.
• Furthermore, changing light conditions does not make projection conditions any more difficult. The contrast of projection material is adjustable accordingly. • This special material can be sawn, drilled, milled and edge-machined. These properties make it the ideal material for designing eye-catching items, attention-grabbing displays, effective signs and dynamic, colorful tradeshow booths and store fixtures. NB!!! The forming temperature is between 150 and 160°C. |

| • The images are displayed on the interactive terrestrial sphere (Globe/Globus/Глобус) using a special developed projector with frame, additional optical part, and a mechanical part for calibration.
• A seamless, de-skewed projection is created to present the contents across the entire surface of the concave lens. |

• The display system was optimized specially for the dome-shaped screen geometry
• Different mappings are available and controllable via an API. The mapping variants are illustrated in the following Fig.:
