Abstract
Nowadays people live in the deluge of information. Although dissemination of information, people wander in excessive alternatives while they make decisions. This study deals with degree how well users can access and control the products or services, namely levels of users’ functional intervention. To demonstrate correlation between situational confusion and levels of users’ functional intervention, we examine related work such as multiple tasks, automation and cognitive load. We consider levels of users’ functional intervention as a criterion to find an effective way to reduce mistakes from cognitive load. The conceptual model between levels of users’ functional intervention and cognitive load is established, and then we propose an experimental design and present a method to elicit the optimal level of functional intervention that generates minimum cognitive load.
