hudlim
Hudlim is a term used in human–computer interaction and design to denote the maximum permissible information density in a head-up display (HUD) before user performance degrades. The term, combining HUD and limit, describes guidelines for content selection, layout, and temporal presentation in HUDs across domains such as automotive, aviation, and augmented reality.
Origin and scope refers to a design principle rather than a standardized specification. The concept emerged
Measurement and evaluation are context dependent. Researchers assess hudlim through controlled experiments that measure task performance,
Applications span several industries. Automotive HUDs often apply hudlim to limit alerts to high-priority items to
Criticism and alternatives note the challenge of universal applicability due to individual differences and context dependence.
