Creating inclusive automotive interfaces using situation awareness as a design philosophy

Abstract

This paper presents a methodology for designing automotive user interfaces using Situation Awareness (SA). The development of interfaces providing users with relevant, timely information is critical for optimal performance. This paper presents a variation on the original SA model allowing for a consideration of all situational factors in a modern motor car. “Dual Goal SA” provides environmental and cognitive considerations for developing interfaces used when multi-tasking. A pilot study was carried out to test the Dual Goal concept and identify appropriate measures. Subjective results proved inconclusive. Objective results showed good evidence supporting the hypothesis but most promising was a factor analysis involving all key objective measures. This produced factors that classified the experimental groups consistently with predictions, demonstrating evidence of variations in performance consistent with variations in SA for two competing goals.
