Evaluation of interfaces presenting information to a person in terms of visual fields and the amount of information provided

Methods for presenting information by utilizing a visual field (such as driver peripheral vision) are attracting increased attention in association with an increase in the amount of information required for driver assistance. However, studies on interfaces utilizing such a visual field are currently...
