'Turn right please' Why navigation screens should obey the rules of perception

摘要

Centuries ago the only dynamic screen was a stage. The width of a stage is greater than it's height. The successor of the stage is the screen a movie is projected onto. It has a landscape orientation. That makes sense. The same applies to the next technological successor, the TV screen. TV screen technology was used for computer screens. Computer screens have a landscape orientation as well. Does that make sense for car navigation screens?
