In order to survive, human beings and animals have a great need to immediately and enconditionally detect dangers and concerns wherever they may occur within the field of vision as well as a need of monitoring those, also in the case, where the central vision is directed towards another sector of the field of observation. These conditions of living may also be solved for technical dangers and concerns such as vehicles, aircrafts, beacon lights etc. Through stimulation using visual perception stimulators, which present effects of contrast and motion, thereby becoming visible within the entire field of vision at the intended distance, regardless of the light conditions in the surrounding area. A shading effect leads to the visibility being particularly manifest and distinct during foggy and snowy as well as sunny conditions. The shading effect also prevents isoluminance. By the use of visual perception stimulators having concurrent movements, particularly vivid effects of motion and distinctive patterns of motion may be generated. The particular vividness through controlling one or more secondary contrast members using patterns of screening, which differ from that of the primary contrast member, yet concurring during some part of the period. |
