解像度制御を用いた閾下刺激による注意誘導効果の評価

抄録

In this study, we evaluated a method for eliciting user attention without their conscious recognition. We focused on exploiting characteristics of the human visual field to determine the effectiveness of attention induction by rendering a portion of the visual field at an imperceptibly high resolution as the inducing stimuli. The proposed method utilizes a head-mounted display that aligns with the visual field characteristics of the user and presents a resolution accordingly. Moreover, areas intended to guide attention are maintained at a high resolution as guiding stimuli. To assess this approach, we conducted an experiment with 10 participants, measuring eye gaze and evaluating attentional behavior in a visual search task with and without the presentation of guided stimuli. The results indicated attention-inducing effects in certain directions of the visual field. Additionally, the findings suggested the possibility of latent attention being directed towards the guided stimuli, even without influencing conscious gazing behavior.
