Abstract:Wearable displays may enhance information access, but potential interference between device use and the primary operational task may result. Multiple Resource Theory (2002) helps predict which information modalities will interfere, but in the case of head mounted displays (HMDs), the importance of competition for focal attention versus central processing resources in determining dual-task interference remains unclear. We investigated the interference between manual tracking and a word memory task, where words … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
