Optic flow is important perceptual information for regulating behavior in humans and other organisms (observers) with visual organs. This study investigated the effects of global optic flow (GOF) caused by observer movement and local optic flow (LOF) resulting from object movement on visual search. In this experiment, GOF consisted of a group of dots diffusing from the center of the screen to the outside of the screen with constant acceleration; the LOF was a single ring of dots expanding with constant acceleration. LOF was randomly generated from one of the eight placeholders equidistant from the center of the screen and equally spaced from each other. The objective was to visually locate and distinguish the numbers (targets) that appeared after LOF vanished, both with and without GOF. The interaction between “the positional relationship between LOF and the target” and “the time interval between the disappearance of LOF and the presentation of the target” was significant in the reaction time. Therefore, the expanding ring may have served as a cue to focus on the diagonal target within the screen. Additionally, an analysis of the distribution of gaze data showed that when GOF was presented, the gaze was drawn more frequently through its central region. According to these results, the gaze was directed toward the area where the GOF and LOF were parallel.

本研究は靴紐の締め方の強弱(tightness)が歩行動作に与える影響を明らかにすることを目的とした.実験参加者は男性9名(22.8±1.2歳),女性9名(21.9±1.8歳)とし,歩行課題(自然歩行,努力歩行)と靴紐の締め方の強弱(fit条件,loose条件)を操作した歩行実験を行った.Kinect v2を用いた歩行姿勢測定システムで歩行速度,歩幅,歩隔を,体幹2点歩行動揺計で歩行周期時間,胸椎背部(以下,Th6)および仙骨付近(以下,S2)における3方向(左右,上下,前後)の平均動揺量とHarmonic Ratio(以下,HR)を計測,算出した.すべての分析項目を用いて対応のある二元配置多変量分散分析を実施した結果,歩行課題と靴紐条件について主効果が認められた.loose条件ではfit条件よりも,歩行速度,S2の上下動揺量,Th6の上下方向のHRは有意に小さく,Th6の左右動揺量,S2の前後動揺量は有意に大きかった.本研究より,靴紐の締め方が緩い(loose条件)と歩行中の体幹の動きに影響を与えることが示された.

Many of elderly people are not good at operation of PC with mouse and keyboard, because they need more time to experience to get enough skill. Through the observation to them in PC school, their characteristics are different from the younger people's movements. In this study, the difference of mouse operation between elderly people and younger people became clear by measurement of mouse movement. Mouse rotation in the horizontal pointing operation can make some difference among them. The volume of acceleration to the target would be the cause of the difference. From the result, we can find out the needs for development of mouse movement system which consider the elderly people's operation characteristics.
