Human Reliance on an Automated Combat ID System: Effects of Display Format

Abstract

Informing users of reliability levels can engender more appropriate reliance on automated systems. In an experiment, reliability information was presented on a rifle-mounted interface for an automated combat identification (CID) system to participants in a first-person shooter simulation of a combat environment. Results showed two effects: First, a mesh display supported better discrimination of hostile and friendly targets than did a pie chart. Second, participants shown an integrated display were better able to adjust their reliance to the changing reliability level than participants shown separated displays. Providing reliability information changed participants' reliance strategies; however, display integration appears to play a role in how system reliability information is used.
