| Outline of Final Research Achievements |
This study evaluates the attentiveness of users in scenarios such as using smartphones while walking on crowded station stairs, using mobile devices in confined spaces, and other situations involving movement. It measures changes in gait during walking and ascending/descending stairs. The study discusses the decrease in attentiveness during mobile device usage, which has become increasingly diverse in its forms. To examine the attention users pay to their surroundings while walking and using stairs, a measurement system comprising eye cameras and other devices was created, and changes in attention were analyzed. Basic experiments were conducted to examine the reactions of mobile device users when performing evasive actions. Physiological state measurements were also conducted to estimate the burden on users.

歩行中や人混み中での携帯端末利用が，利用者自身と周囲への安全に影響を及ぼすことは広く認識されている．特に，移動しながらの携帯端末利用（所謂歩きスマホ）が高齢者等の歩行弱者への安全に影響を及ぼすことから，各種対策が検討されているものの，依然として周囲が注意を払い危険回避せねばならない状況である．一方、増加している高齢者による歩きスマホも自身の不安定な歩行に繋がる．本研究では，歩きスマホ時の平地・階段昇降時の歩行変容を計測した．対向者に対して危険回避行動する際の反応を検討するための基礎実験を行った．高齢者にありがちな前傾姿勢での歩きスマホ時の特性，複雑なスマホ操作時の足の動きの変化も調査した．
