本文介绍了从空间增强现实（SAR）的研究，评估了几个预测线索的认知成本的结果。参与者执行了一个经过验证的程序按钮按下任务，其中预测提示注释引导他们到即将到来的任务。虽然现有的研究已经根据他们的表现和自我评估的心理努力来评估预测线索，但实际的认知成本还有待调查。为了测量用户的大脑活动，这项研究利用了脑电图（EEG）记录。通过测量次级听觉古怪任务的大脑反应来评估认知负荷，当主要任务中的认知负荷最高时，预期大脑对古怪音调的反应会减少。进行了一个简单的监视器n-back任务和程序任务比较监视器与SAR，其次是一个版本的程序任务比较SAR预测线索。来自大脑反应的结果能够区分具有高认知负荷和低认知负荷的性能增强线索。脑电反应还显示，用弧形或箭头引导即将到来的任务需要的脑力劳动最少。
This article presents the results from a Spatial Augmented Reality (SAR) study which evaluated the cognitive cost of several predictive cues. Participants performed a validated procedural button pressing task, where the predictive cue annotations guided them to the upcoming task. While existing research has evaluated predictive cues based on their performance and self-rated mental effort, actual cognitive cost has yet to be investigated. To measure the user's brain activity, this study utilized electroencephalogram (EEG) recordings. Cognitive load was evaluated by measuring brain responses for a secondary auditory oddball task, with reduced brain responses to oddball tones expected when cognitive load in the primary task is highest. A simple monitor n-back task and procedural task comparing monitor versus SAR were conducted, followed by a version of the procedural task comparing the SAR predictive cues. Results from the brain responses were able to distinguish between performance enhancing cues with a high and low cognitive load. Electrical brain responses also revealed that having an arc or arrow guide towards the upcoming task required the least amount of mental effort.
