Ergonomic product design can be divided into the parts of physical ergonomics (anthropometrics) and cognitive ergonomics. I regard to the visual cognition, the anthropometric and cognitive ergonomics are very closely connected. The visual cognition process is based on physical as well as psychological components. The information processing in the brain needs the visual perception with the eyes. This visual perception needs some optical attributes for good viewing conditions of the eye. The international widely-used 3D-Man-Model System RAMSIS receives some additional functionality for analysis and practical design of to simulate these viewing conditions in the car. These new RAMSIS functions include methods for the analysis of reflective glare, visual acuity, reading precision, visual fields, limited accomodation, glasses, progressive addition lenses and electronic displays. These capabilities will enable a RAMSIS user to allow for (degraded) visual performance when designing user interfaces displays in cars.     «
