Outline of Final Research Achievements

We investigated postures during daily smartphone use and differences in risk judgment by posture during smartphone use. The results of our survey of 600 males and females in their teens to 60s showed that they spent the most time operating their smartphones in the posture of sitting forward with their hands on a desk and leaning back without a desk. Moreover , comparison of the behavior in a gambling game on a smartphone while sitting bent forward or leaning backward revealed that the forward leaning posture made risk judgments more severe than those in the backward leaning posture.

Academic Significance and Societal Importance of the Research Achievements

多くのスマートフォン用のゲームアプリでは「ガチャ」と呼ばれる抽選方式の課金システムが採用されており、過剰な課金やゲーム依存を生み出す要因の1つとして問題視されている。本研究によって前屈みの姿勢で操作すると損失に対する注意が高まることが示されたことから、ガチャのようなギャンブル性の高い課金システムを利用する際は、前屈みの姿勢で操作した方が過剰な課金に至る危険性を減らせることが示唆された。
