A new tilt on computer generated Space Station displays

In theory, globes appear to make excellent maps. There are, however, drawbacks which make them difficult to use. It became, therefore, necessary to project a map of the earth on a flat surface. In connection with air and space travel, there is now a need for accurate 'three-dimensional' projections. The considered projections are not true 3D, but rather '3D-looking', perspective 2D map displays. Computer representations of space situations provide flat two-dimensional maps and three-dimensional globe displays. However, none of these display techniques are entirely satisfactory in all situations. An investigation of alternate display techniques was, therefore, conducted, taking into account a display, called the '3D' hybrid display. Pilot studies were performed with the aim to assess the advantages of the hybrid display for depicting satellite situations. It was found that the subjects prefer the hybrid display over the flat 2D display even though it does not significantly aid their performance.
