    This study aims to explain the behavioral characteristics of people encountering a fire in an underground shopping mall using a VR system that enables them to control their avatars with physical movements. In Experiment 1, the distance to the exit light was changed so that the visibility of the exit light in the VR space smoke would be the same as that in the real space. The participants adjusted the density of the smoke so that the exit light could be seen. In Experiment 2, based on the results of Experiment 1, the behavior of the research participants was measured at the underground mall where the fire occurred in the VR space. The results indicated that most of the participants evacuated from the nearest exit, however, some of them evacuated from the farther exit. This may be due to individual differences in the way the participants used the evacuation exit guide lights and in the formation of the cognitive map that is the basis of the Survey Map, which is used when people encounter unexpected situations in their spatial behavior.

    Humans navigate urban spaces by relying on two different types of spatial memory, namely route maps and survey maps. Conventional experiments that reveal human behavioral characteristics in urban spaces are not only costly in terms of the personnel required for measurement and analysis of large amounts of data but also lack reproducibility of the actual experimental environment. To solve these problems, we propose a system to construct an urban space in virtual reality (VR) using physical movements and exploration. However, it is not clear what type of cognitive maps are formed in the human brain when exploring urban spaces using survey maps. Therefore, the primary purpose of this study is to quantitatively evaluate the cognitive map formed in VR space using geometrical and statistical properties. Experiments were conducted in both spaces, and the geometrical properties of distortion of the cognitive map did not show any specific tendencies for deviation from the real survey map, whereas the statistical properties showed high correlations with the real map. These results indicate that there are no differences in the cognitive maps formed by experiments conducted in two different spaces.

    Vection is illusory self-motion elicited by visual stimuli and is more easily induced by radial contraction than expansion flow in adults. The asymmetric feature of vection was reexamined with 18 younger (age: 6–8 years) and 19 older children (age: 9–11 years) and 20 adults. In each experimental trial, participants observed either radial expansion or contraction flow
    the latency, cumulative duration, and saturation of vection were measured. The results indicated that the latency for contraction was significantly shorter than that for expansion in all age-groups. In addition, the latency and saturation were significantly shorter and greater, respectively, in the younger or older children compared with the adults, regardless of the flow pattern. These results indicate that the asymmetry in vection for expansion or contraction flow emerges by school age, and that school-age children experience significantly more rapid and stronger vection than adults.

    We present a hard-wired central patter generator (CPG) hardware network that reproduces the periodic oscillations of the typical gaits, namely, walk, trot, and bound. Notably, the three gaits are generated by a single parameter, i.e., the battery voltage E-MLR, which acts like a signal from the midbrain's locomotor region. One CPG is composed of two types of hardware neuron models, reproducing neuronal bursting and beating (action potentials), and three types of hardware synapse models: a gap junction, excitatory and inhibitory synapses. When four hardware CPG models were coupled into a Z(4) symmetry network in a previous study [22], two neuronal oscillation patterns corresponding to four-legged animal gaits (walk and bound) were generated by manipulating a single control parameter. However, no more than two neuronal oscillation patterns have been stably observed on a hard-wired four-CPG hardware network. In the current study, we indicate that three neuronal oscillation patterns (walk, trot, and bound) can be generated by manipulating a single control parameter on a hard-wired eight-CPG (Z(4) x Z(2) symmetry) hardware network.

    Recent studies have found that self-motion perception induced by simultaneous presentation of visual and auditory motion is facilitated when the directions of visual and auditory motion stimuli are identical. They did not, however, examine possible contributions of auditory motion information for determining direction of self-motion perception. To examine this, a visual stimulus projected on a hemisphere screen and an auditory stimulus presented through headphones were presented separately or simultaneously, depending on experimental conditions. The participant continuously indicated the direction and strength of self-motion during the 130-s experimental trial. When the visual stimulus with a horizontal shearing rotation and the auditory stimulus with a horizontal one-directional rotation were presented simultaneously, the duration and strength of self-motion perceived in the opposite direction of the auditory rotation stimulus were significantly longer and stronger than those perceived in the same direction of the auditory rotation stimulus. However, the auditory stimulus alone could not sufficiently induce self-motion perception, and if it did, its direction was not consistent within each experimental trial. We concluded that auditory motion information can determine perceived direction of self-motion during simultaneous presentation of visual and auditory motion information, at least when visual stimuli moved in opposing directions (around the yaw-axis). We speculate that the contribution of auditory information depends on the plausibility and information balance of visual and auditory information.

    The authors examined whether the perceptual reversal rate changes under monocular versus binocular viewing conditions. Our results suggest that the perceptual reversal interval increases during monocular viewing. The ratio of the reversal rate (1/interval) for the two viewing conditions (binocular/monocular) was 1.28 over a wide range of pattern luminance levels. The quoted ratio was 1.40 when the luminance was high. Such a ratio parallels the value of a well-known binocular summation index , which was derived from the signal detection theory. The binocular summation index shows that the strength of an input signal is enhanced by binocular viewing. However, how the binocular summation shortens the perceptual reversal interval is unclear. This issue can be resolved if the perceptual reversal is derived by integrating the strength of an unconscious image signal. Thus, we discussed the mechanism of perceptual switch by associating two classical, well-studied phenomena, binocular summation and perceptual switch.

    The visual-vestibular conflict theory asserts that visual-vestibular conflicts reduce vection and that vection strength is reduced with an increasing discrepancy between actual and expected vestibular activity. Most studies support this theory, although researchers have not always accepted them. To ascertain the conditions under which the theory of the visual-vestibular conflict can be applied, we measured circular vection strength accompanied by manipulation of the visual-otolith conflict by setting the axes of visual global motion (pitch, roll, and yaw) as either earth-horizontal or earth-vertical, using three different body positions (supine, left-lateral recumbent, and sitting upright). When the smaller stimulus was used, roll vection strength was greater with the visual-otolith conflict than without it, which contradicts the visual-vestibular conflict theory. We confirmed this result, as observers were able to distinguish circular vection from an illusory body tilt. Moreover, with observers in an upright position, the strength of yaw vection, which does not involve the visual-otolith conflict, increased and was almost equal to that of roll vection, which involves the visual-otolith conflict. This suggests that if the visual stimulus covers the entire visual field, the strength of circular vection around the earth-vertical axis exceeds that around the earth-horizontal axis, which is a finding consistent with the visual-vestibular conflict theory.

  • Effects of visually simulated roll motion on vection and postural stabilization Reviewed

    Background: Visual motion often provokes vection ( the induced perception of self-motion) and postural movement. Postural movement is known to increase during vection, suggesting the same visual motion signal underlies vection and postural control. However, self-motion does not need to be consciously perceived to influence postural control. Therefore, visual motion itself may affect postural control mechanisms. The purpose of the present study was to investigate the effects of visual motion and vection on postural movements during and after exposure to a visual stimulus motion.
    Methods: Eighteen observers completed four experimental conditions, the order of which was counterbalanced across observers. Conditions corresponded to the four possible combinations of rotation direction of the visually simulated roll motion stimulus and the two different visual stimulus patterns. The velocity of the roll motion was held constant in all conditions at 60 deg/s. Observers assumed the standard Romberg stance, and postural movements were measured using a force platform and a head position sensor affixed to a helmet they wore. Observers pressed a button when they perceived vection. Postural responses and psychophysical parameters related to vection were analyzed.
    Results: During exposure to the moving stimulus, body sway and head position of all observers moved in the same direction as the stimulus. Moreover, they deviated more during vection perception than no-vection-perception, and during no-vection-perception than no-visual-stimulus-motion. The postural movements also fluctuated more during vection-perception than no-vection-perception, and during no-vection-perception than no-visual-stimulus-motion, both in the left/right and anterior/posterior directions. There was no clear habituation for vection and posture, and no effect of stimulus type.
    Conclusion: Our results suggested that visual stimulus motion itself affects postural control, and supported the idea that the same visual motion signal is used for vection and postural control. We speculated that the mechanisms underlying the processing of visual motion signals for postural control and vection perception operate using different thresholds, and that a frame of reference for body orientation perception changed along with vection perception induced further increment of postural sway.

    本研究では提案時より4項目 ①ヘッドマウントディスプレイHMDによる複雑環境の提示，②頭部非固定眼球運動調節測定，③高精度眼光学モデル，④深層学習(神経系モデル)に分けて研究を進めている．
    2021年度は①HMDシステムの心理物理実験応用に関して， VR空間と実空間の視対象の見えの大きさと視対象までの距離の知覚誤認について研究を進めた．このために実空間にある正方形の網膜上の残効とVR空間にある正方形の大きさの比較実験，対照実験として前者を実空間の正方形として比較する実験を行い．２つの実験結果を比較することにより，視対象の像の大きさはHMDの光学系の影響を受けないことと，VR空間では実空間と比べて視対象までの距離が遠くなると視対象の見えの大きさを過小評価することを確認した．さらに評価を進めることにより，HMD上での大きさの過小評価は，HMDの光学系の影響ではなく立体視時に生じる輻輳と調節の矛盾が原因と結論づけた．
    ②の眼球運動計測に関しては，アイトラッカー (VOG) と物体検出ディープラーニング (SSD) を組み合わせた眼球運動システム (VOG-SSD システム) を完成させ，眼球運動を他覚的定量評価できることを国際誌 (Hirota et al., Transl Vis Scie Technol, 2021) で報告した．さらに，検査-解析-評価のシームレス化を目指し，VOG-SSDシステムによって測定した視標と眼位情報から，眼球運動の潜時やゲイン (視標の動きに対する眼球の追従率) を自動計算する解析ソフトウエアを開発した．
    ③の眼光学モデリングでは，モデリングのための前眼部，後極部，高次収差をセットとした280例，560眼のデータセットを構築した．このデータセットの信頼性や周辺屈折との関係も調べた．

    There is a need for a mechanism that enables a wheelchair user to smoothly get on and off a train without assistance. In this study, we propose a device that enables a wheelchair user to get on and off a railroad car by lifting the wheelchair according to the height of the step by manual operation by the wheelchair user himself/herself. This mechanism was designed and manufactured in accordance with international and domestic standards ISO/JIS. Through experiments with a dummy load and a human subject, we confirmed that the wheelchair is stable with low vibration while getting on and off the train, and that the basic operation is possible by evaluating the time required to operate the lever when stepping over a step. On the other hand, it was also confirmed that a mechanism to support the lever operation is necessary for users who are light in weight and have low arm strength.
