1.	Akua Kawakami, Haruki Mizushina, Shiro Suyama and Kenji Yamamoto : Analysis and fabrication for the dimensional expansion of arc 3D display to cone-shaped display, Optical Review, 2022. (Summary) This paper successfully describes the analysis between 3D image location in air and arc-shaped scratches on cone-shaped arc 3D display. The arc 3D display is typically flat and its analysis has already appeared. However, when we would like to extend it to cone shape, the dimensional extension of analysis should be necessary, since the lack of adequate analysis increases the approximation error of the 3D image location. In this paper, we discuss the three-dimensional analysis for cone-shaped arc 3D display. In addition, we describe the actual fabrication of a cone-shaped arc 3D display and show that the 3D image can be displayed similarly with the analysis.

(Summary) Electronic holography is an ideal 3-D display technique to ameliorate the vergence-accommodation conflict, which is a possible cause of visual fatigue and discomfort from viewing conventional stereoscopic 3-D displays. Previous studies have measured accommodative and vergence responses to holographic images and to real objects, and the results showed that these responses are in good agreement. To demonstrate the effectiveness of electronic holography as a possible solution to the vergence-accommodation conflict caused by viewing conventional stereoscopic 3-D displays, we measured both accommodative and vergence responses to reconstructed images of holograms and super multiview holographic stereograms. We also measured responses to real objects located at various distances and conventional two-view stereo images for comparison. The results indicate that the accommodative responses to the electro-holographic display and super multiview holographic stereogram change with the vergence response in a similar manner, as is the case with real objects as compared to conventional two-view stereo display. This suggests that the electronic holographic display and super multiview holographic stereograms are promising candidates for resolving the vergence-accommodation conflict.

Haruki Mizushina, Kohei Yamamoto and Shiro Suyama : Unstable depth perception of aerial images in crossed mirror array can be controlled by changing fixation distance, IEEE Transactions on Industry Applications, Vol.58, No.5, 6793-6800, 2022. (Summary) The unstable depth perception of aerial images in a crossed-mirror array (CMA) can be improved by changing the distance of fixation points. The perceived depths of aerial images in CMA suffer from large instability even when an aerial image is a geometrical optical real image. The perceived depth instability of aerial images is mainly influenced by their geometrical position from CMA. The perceived depths of aerial images shift toward the fixation points, and the stable depth perception of aerial images can be obtained if the fixation points are located near the aerial image distance. To stabilize the depth perception of aerial images, it is sufficient to appropriately control the observer's vergence even if the fixation point is not a real object. In addition, the luminance of aerial images affects the stability of their depth perception.

(Summary) This article demonstrates the importance of visual information on depth perception from monocular motion parallax presented at the time of change in the motion direction of head and stimulus movements. In head-tracking systems, a longer delay time between the head and stimulus movements degrades the depth perception from the monocular motion parallax. Because this delay is noticeable at this time, we hypothesized that the visual information given at the time of the direction change plays a critical role in the depth perception from motion parallax. We evaluated depth perception from monocular motion parallax with and without a visual stimulus at the time of the motion direction change to confirm our hypothesis and clarified that stable and unambiguous depth can be perceived by presenting the change of the stimulus motion direction. We also demonstrated that it is the change in motion direction itself that is important rather than the temporal stop between deceleration and acceleration of the stimulus motion.

(Summary) 実物体の知覚的大きさと,写真やビデオ映像などにおけるその物体の二次元像の知覚的大きさが異なることが経験的に知られている.しかしこの現象が,刺激のどのような要素と関連があるのか,またなぜ生じるのかについては明らかであるとは言えない.そもそもこの現象は,実物体とその二次元画像を観察する際の観察条件などの違いによるアーティファクトの可能性も考えられる.そこで本研究では,頭部の三次元模型及び単純な凹凸形状をもつ三次元実物体とそれらの写真画像の知覚的大きさの比較実験により,この現象を定量的に記述し,その原因を明らかにすることを目的とした.実験の結果,頭部模型の二次元画像は実物体より数パーセント程度横に広がって知覚されることが示された.また,単純な物体についても,実物体に対する二次元画像の知覚的大きさの拡大が見られ,その拡大の方向は,対象物体の奥行きに変化がある方向に沿っていることが明らかになった.この現象における,実物体を観察する際に左右眼像に生じる単眼領域の影響,及び実物体とその二次元画像を観察する際の知覚的奥行きの違いによる影響を考察した.

(Summary) A super multi-view (SMV) 3D display has been proposed for reducing conflict between accommodation and vergence, which is a possible cause of visual fatigue. Previous studies reported that measured accommodative responses to SMV images were similar to those of real objects. We need to measure vergence response along with accommodative response to investigate the conflict between them. In this study, we measured accommodative and vergence responses while observers were viewing a static visual target presented on an SMV display. We also examined the responses to two-view displays and real objects for comparison. The results show that the SMV display induced a natural accommodative response relative to the two-view 3D display while no difference was found among the viewing conditions of the vergence response. This suggests that the SMV 3D display is effective for reducing conflict between accommodative and vergence responses.

(Summary) The conflict between accommodation and vergence stimuli has been identified as a possible cause of visual fatigue from viewing stereoscopic images. We examined static and dynamic characteristics of accommodation and vergence responses while viewing stereoscopic displays and real objects to clarify the effect of stereoscopic images on the visual function. We used an instrument based on the Shack-Hartmann wavefront sensor to measure accommodation and vergence responses simultaneously. Accommodation responses to the static stereoscopic target with large binocular disparity were deviated from those to the real target, i.e., static characteristics. The step responses of the accommodation response showed considerable individual differences, i.e., dynamic characteristics. In addition, the asymmetries of step responses of accommodation were observed between the near-to-far and the far-to-near step directions. These results suggest that we need to examine both static and dynamic characteristics of accommodation and vergence responses to clarify the biological effect of stereoscopic images.

(Summary) 機器使用時のユーザの心理的ストレスを客観的に評価するために,心拍や皮膚導電率等の生体信号を用いる手法が提案されている.しかしそれらの手法には電極の装着等の煩わしさが伴うため,それ自体がストレスの原因となる可能性もある.その点において,眼球運動は非接触で計測可能であるため,ストレスの優れた指標になり得ると考えられる.本論文はそのための基礎的な知見を得ることを目的とし,多様な課題の遂行時における眼球運動を計測した.また,そのときの心理状態の主観評価も併せて行い,眼球運動の特性との対応を検討した.その結果,課題によって時間的な切迫感を与えた場合に,振幅の小さいサッカード眼球運動の分布における振幅の平均値と主観的な「焦り感」との間に正の相関が見られた.このことから,サッカード眼球運動の動特性が心理的ストレスの指標として利用できる可能性が示された.一方,課題の遂行に関連すると考えられる振幅の大きなサッカードの分布においては,眼球運動の動特性と心理状態との間に相関は見られなかった.このことから,心理状態は課題の遂行に関連しない振幅の小さい眼球運動により強く反映されると考えられる.

(Summary) 機器使用時におけるユーザの心理的ストレスを客観的に評価することは,人間に優しいヒューマンマシンインタフェースを設計する上で重要である.しかし,従来提案されている心拍・脳波・皮膚電位等の生体信号をストレスの指標とする場合,電極の装着等の煩わしさが生じる.その点において,非接触で計測可能な瞳孔径は優れた指標になり得ると考えられる.また指標の汎用性を考慮すると,幅広い年齢層のユーザに適用可能なことが重要である.本論文ではその基礎的な知見を得るために,若年者と高齢者を対象に,多様な課題の遂行時における瞳孔径を計測し,そのときの心理状態の主観評価との対応を検討した.その結果,本研究で用いた3種類の作業負荷条件下においては,いずれの場合も負荷量の増大とともに瞳孔径変動量が増大した.また,タイムプレッシャーを与えた場合と聴覚刺激の識別難易度を操作した場合においては,心理的ストレスの要因となり得る「不安感」の主観評価と瞳孔径変動量との間に相関が見られた.瞳孔径変動に関しては,定性的には若年者と高齢者でほぼ同様の挙動が観察されたため,心理的ストレス指標として幅広い年齢層に適用できる可能性が示された.

(Summary) The cyclopean illusion is the apparent lateral shift of stationary stimuli on a visual axis that occurs when vergence changes. This illusion is predictable from the rules of visual direction. There are three stimulus situations reported in the literature, however, in which the illusion does not occur. In the three experiments reported here we examine those stimulus situations. Experiment 1 showed that an afterimage seen on a stimulus moving on the visual axis does not produce the illusion as reported in the literature but an afterimage seen on a screen does. Experiment 2 showed that the illusion occurs for an intermittently presented stimulus in contrast to what has been reported previously. Experiment 3 showed that a monocular stimulus presented against a random-dot background produced the illusion, also in contrast to what has been reported. The results were consistent with the rules of visual direction.

(Summary) Arc 3D display with moving head or moving Arc 3D display can successfully solve the perceived-depth sticking problem to real object surface in front of designed distant 3D image, although stereoscopic display cannot solve the sticking problem. This is because continuous motion parallax is satisfied in Arc 3D display but not in stereoscopic display, which is effective to perceive the designed depth.

(Summary) We introduce three experiments on depth perception from monocular motion parallax for more realistic depth representation in 3D applications. Motion parallax is a physiological factor for depth perception. When moving the head position, depth can be perceived from motion parallax even when using one eye because motion parallax provides enough information for depth estimation. In our first experiment, we evaluated the perceived depth from monocular motion parallax with passive head movements. The results show that perceived depth with passive head movement is comparable to that with active head movement. For more realistic 3D scenes, we should clarify the critical factor of visual information in motion parallax. Therefore, in our second experiment, we evaluated the perceived depth from motion parallax with and without direction change of the stimulus movement. The results suggest that visual information at the time of direction change plays an important role in stable and unambiguous depth perception. In our third experiment, we evaluated the minimum duration of motion parallax stimulus with direction change for stable and unambiguous depth perception. The results indicate that a stimulus duration of only 15% of the total trial time provides stable and unambiguous depth perception if direction changes of the visual stimulus are presented. These findings can be applied to 3D applications using motion parallax.

(Summary) We can successfully achieve rewriting or switching 3D images in Arc 3D display by separately illuminating desired arc-shaped scratches in 3 × 3 scratch array and changing perceived depth by illuminating angle change. Conventional Arc 3D display has difficulty in rewriting its 3D images because perceived depth is changed by arc radius change. We propose a new method of illuminating only desired arc-shaped scratches of scratch array with the same radius and changing perceived depths by illumination angle change of several projectors. Moreover, we evaluated the limit of separate illumination from neighborhood scratches by changing pitches of scratch array. At array pitch of 3 mm, large unseparable region leads to difficulty in rewriting. On the other hand, at array pitch of 5 mm, small unseparable region result in possibility of rewriting. Thus, rewriting or switching 3D images in Arc 3D display can be successfully achieved.

(Summary) We have proposed and estimated a new simple 3D display utilizing occlusion effect by frames and/or gap in side-by-side 2D displays over horizontally moving stimuli, by which even stereo-blind people can enjoy 3D perception. Wholly perceived depths can be significantly enlarged from 0.5 cm by single 2D display to around or over 3 cm by occlusion frames and/or gap between two 2D displays, regardless of stimuli moving direction. Occlusion frames and occlusion frames and gap also have significant difference in perceived depth. By local observation of 10 divided positions in displays, individual perceived depths significantly have difference between 2-3 cm at occluded positions and around 1 cm at other positions. As moving speed increases, perceived depths at occluded positions are significantly enlarged. Thus, our proposed 3D display can successfully improve perceived depths by utilizing occlusion effects in frames and/or gap of side-by-side 2D displays.

Kohei Yamamoto, Haruki Mizushina and Shiro Suyama : Perceived Depth Instability of Aerial Image by Changing Image Position from Crossed Mirror Array, The 19th International Meeting on Information Display, 661, Gyounju, Aug. 2019. (Summary) Perceived depth instability of aerial image is not influenced by observation distance but by geometrical position of aerial image from CMA. In order to clarify the reason for perceived depth shift to CMA by near observation position from geometrical position of aerial image, we estimated perceived depth dependence when image position from CMA is changed with constant distance between subject and aerial image. when distances from CMA of aerial image are as small as 20 cm and 40 cm, aerial images can be perceived near designed positions of 20 cm and 40 cm. These aerial image positions are same as geometrical position of aerial image. However, when distances between CMA and aerial image are increased to 60 cm and 80 cm, aerial image positions have large deviations and are separated to designed depths near 60 cm and 80 cm from CMA and CMA surface.

(Summary) Even when rear real object is occluded by front real object partially, DFD(Depth-fused 3D) display can successfully achieve sufficient perceived depth change from behind front real object to in front of front real object by adding image of rear real object with a gap and changing its luminance. For various applications of 3D display combined with real objects, we clarify possibility of perceived depth change of real objects by using DFD display. By adding rear object image behind rear object, perceived depth can be easily changed behind rear object in proportion to image luminance. Moreover, in spite of strong cue by occlusion for judging front or rear position, perceived depth of occluded rear object can be surprisingly changed in front of front object by adding rear object image in front of front object. Thus, perceived depths of objects even when including occlusion can be freely changed.

(Summary) Long-viewing distance 3D display will be promissing for many outdoor applications such as digital signage, street advertising and etc. We consider DFD(Depth-fused 3D) display only composed of layered LED displays is appropriate for such outdoor applications and have proposed Non-overlapped DFD display by solving the problem of non-transparency of LED display. Small-light source was composed of a hole with 6 mm diameters, illuminated by a projector. A high speed shutter in front of projector lens controlled the display time to long time or 10 ms. The liminance ratio between front and rear images was randomly changed in five levels. Perceived depth was estimated by matching the reference image depth with the perceived image depth. Observation deitances are 5 m and 10 m. In conclusion, even at short display time of 10 ms, easy depth fusion and appropriate perceive depth dependence can be obtained by enlarging observation distance to 10 m.

Kyohei Okamoto, Haruki Mizushina and Shiro Suyama : Large Depth Perception by Monocular Motion Parallax in DFD Display, The 18th International Meeting on Information Display, 183, Busan, Aug. 2018. (Summary) Not a few people, called stereo-blind, cannot perceive 3D image depth only by using binocular disparity. Even for such stereo-blind people, monocular motion parallax is effective. We have proposed large depth perception in DFD display by using continuous monocular motion parallax for stereo-blind people. DFD display is composed of front and rear images overlapped. There is the problem of depth fusion limit in front-rear gap in DFD with both eyes. When front-rear gap is larger than about 6 arcmin., disparity excessibely increases, and difficult to fuse front and rear images. We propose the solution for large depth depth perception by using monocular motion parallax. In monocular motion parallax, disparity can be maintained to moderate level by controlling head motion widtrh. Experimental, perceived depth was evaluated by moving the reference to the perceived depth position. Result, by using monocular motion parallax, two images can fused to one depth and its perceived depth coincides the theoretical line.

(Summary) We propose a new method of 3D display using layered multi-view displays, to obtain smooth image shift and appropriate perceived depth of motion parallax with a small amount of informations. DFD (Depth-fused 3D) display technology is also used for the layered images to reduce the amount of informations. The proposed display is composed of layered multi-view displays with a gap. Our method has three mechanisms to obtain smooth image shift and appropriate perceived depth of motion parallax. Firstly, this method can simply increase the number of viewpoints by using several multi-view displays. Secondly, direction differences of parallax by the gap between layered multi-view displays results in increasing effective number of inconsistent parallax. Thirdly, our display has small motion parallax because DFD display has small motion parallax. In the experiments perceived depths in the layered multi-view DFD display are much improved from degraded depths in the multi-view display. Thus, our layered multi-view DFD display has smooth image shift as compared to those of conventional method. These results lead to the conclusion that our proposed method by using layered multi-view DFD display is promising for providing smooth image shift and monocular appropriate depth perception of motion parallax.

(Summary) We have clarified that stimulus movement at changing moving direction of head is important for stable depth stimulus perception from monocular motion parallax and that depth can be perceived if the ratio of the movement width of the head and stimulus is known. In our previous, visual information at the time of changing moving direction of the head and stimulus is important in order to perceived stable depth from monocular motion parallax. However it is not clarified whether the stimulus movement at changing moving direction of the head or ratio of the stimulus movement corresponding to the head movement is important. In this study, we evaluated the perceived depth in monocular motion parallax by presenting stimulus only when stopping head and stimulus movement at changing moving direction.

(Summary) We have clarified that perceived depth from monocular motion parallax in VELF3D (Visually Equivalent Light Field 3D) display using linear blending technology can be linearly changed according to the theoretical value. Linear blending technology can display psychological smooth parallax change by linearly mixing the image luminance between neighborhood viewpoints according to the observation position. In this study, we evaluated the monocular depth perception in VELF3D display, which is another aspect of motion parallax, and clarified the possibility of monocular depth perception by smooth and undelayed motion parallax.

(Summary) In recent years, arc 3D display has been developed an new 3D display technology. Arc 3D display was reported by W.Beaty as a simple fabrication method of 3D image. In addition, Arc 3D display has smooth motion parallax. However, conventional arc 3D display provides only static 3D image. Liquid-crystals(LC) devices have been proposed for making arc 3D moving images. In this study, active device using dual-frequency LC has been proposed,which switch on/off directional scattered light by frequency change. (Keyword) light / polarization

(Summary) There are great differences between individual in visual discomfort caused by viewing stereoscopic images. In this study, we hypothesized that individual differences in the disparity range for comfortable viewing of stereoscopic images relate to those in the visual function. The results suggest that the subjects with narrower pupil distance, higher visual acuity of dominant eye, and higher stimulus AC/A ratio showed narrower disparity range for comfortable viewing of stereoscopic images. The individual differences in accommodation responses to real objects and stereoscopic images were not correlated to the individual differences in the disparity range for comfortable viewing of stereoscopic images.

(Summary) Conventional three-dimensional (3D) displays have a conflict between accommodation and vergence stimuli. This accommodation-vergence conflict is one of the possible causes underlying visual fatigue and discomfort while viewing 3D displays. The super multi-view (SMV) display technique has been proposed to reduce the conflict. In this study we examined whether SMV displays can reduce the conflict by measuring accommodation and vergence responses simultaneously. The results show that the super multi-view display enhanced the range in which accommodation changed compared with the conventional two-view stereo display. As a result, the accommodation-vergence conflict can be solved by SMV displays.

(Summary) We measured the latency of P-100 (positive peak around 100msec) in Visual Evoked Potential (VEP) before and after visual tasks in 3D presented or real spaces. The latencies of P-100 extended after the tasks both in 3D presented and real spaces. This result suggests that the extension of the latency of P-100 reflects only the visual fatigue by vergence eye movement, which is not 3D-specific factor.

(Summary) The conflict between accommodation and vergence is one of the possible cause of visual fatigue while viewing stereoscopic display. Traditional two-view and multi-view stereoscopic displays cannot match distance information of accommodation with that of vergence, however, in principle, reconstructed 3D images of electronic holography can. In this study we measured accommodation and vergence responses simultaneously while viewing stereoscopic images of holographic, super-multi view (SMV), and two-view displays. Accommodation and vergence responses to holographic and SMV stereoscopic images were similar to the responses to the real target.

The performance was decreased only after observation of 3D display and not decreased after observing real objects. These results were not matched to the results of subjective assessment of visual fatigue and suggest that the quality of visual fatigue while observing 3D display is different from that of real objects.

(Summary) The conflict between accommodation and vergence is one of the possible causes of visual fatigue while viewing stereoscopic display. To know how much conflict is acceptable for safe and comfortable viewing, we need to compare accommodation and vergence responses while viewing stereoscopic images to those while viewing objects at real distances. In this study we measured accommodation and vergence responses while viewing a visual target located at real distances and simulated distances presented on a stereoscopic display. We also showed that the display frame had no effect on accommodation and vergence responses while viewing stereoscopic display.

(Summary) Pupil diameter changes with psychological state and with brightness of visual stimulus. The property of the interaction between the two functions is not clearly known. In this research, we manipulated the psychological state of the observers using auditory stimuli under various brightness conditions and measured the diameter of pupil to investigate the interaction of the effects of psychological state and of brightness on pupil diameter. The results show that mean pupil diameter increased as the task became more difficult under low brightness level but that pupil diameter was almost unchanged by the difficulty of the task under the high brightness level.

(Summary) The perceptual trajectory of a moving object often differs from its physical trajectory. This bias in motion perception could be related to the motion bias in the natural environment produced by gravitational acceleration. Our previous study showed that subjects perceived a moving dot with downward acceleration as having uniform velocity, suggesting that perceptual baseline is biased by the acceleration in the vertical direction,. And our previous study also showed that perceptual baseline of motion is biased along both of the direction of gravity and the direction of retina. In this study, we examined about this bias along two directions on perception of moving target with perceptual uniform velocity in details.

HIP, Vol.108, No.27, 125-130, May 2008. (Summary) We carried out experiments to measure the effect of the task workload on pupil diameter variability and psychological state using two kinds of task. One was time-based task in Experimentl, and the other was cognitive-based task in Experiment2. Pupil diameter (PD) was monitored and recorded by means of infrared video camera, while observers performed time-based task using auditory stimuli which was presented at different time intervals and cognitive-based task using auditory stimuli which was presented at different levels of the cognitive difficulties. After each trial, observers responded their subjective psychological state during the trial. In both experiments, the results showed that subjective responses of "activity", "time pressure" and "anxiety" increased according to increasing the level of the task workload. Moreover, using the same frequency band as that of heart rate variability (LF/HF), in both experiments, significant correlations were observed between the ratio of lower frequency components to higher components (LF/HF) of PD fluctuations and the subjective psychological state. These results indicate that LF/HF of PD fluctuations will be effective evaluation indices for mental stress, and the optimum bands for LF/HF of PD fluctuations change by the kind of task and the bands for cognitive-based task will shift to higher frequency than that for time-based task.

HIP, Vol.108, No.27, 109-112, May 2008. (Summary) We often have an impression that perceived size (aspect ratio) of a real three-dimensional object is different from that of the two-dimensional picture of the object. In this research, we quantitatively measured this difference in perceived sizes of 3D and 2D representations of an object and discussed the cause of the difference if the effect would really exist. Observers adjusted horizontal size of the stimulus picture presented on a display to mach the apparent size of the original real object. The shape of the stimulus object was flat, concave or convex. The results showed that the perceived size of 2D image was different from that of 3D object at 185cm of viewing distance when viewing binocularly. Perceived horizontal size of 2D image was enlarged relative to that of 3D object. In addition, this effect decreased when viewing monocularly. These results indicated that existence of half occluded region which arises in binocular viewing, has an important role in this difference between perceived sizes of 2D image and 3D object.

In addition, we investigated the effects of aging in this relationship. To manipulate observer's psychological state, we changed the difficulty of the task or the discriminability of stimuli by adding noise. After each trial, observers responded their subjective psychological state during the trial. The results show that mean pupil diameter increased as the difficulty of the task increased.

ME and bio cybernetics, Vol.107, No.248, 23-26, Oct. 2007. (Summary) This paper examined the effect of the workload on fluctuations in pupil diameter and psychological state. Pupil diameter (PD) was monitored and recorded by means of infrared video camera, while observers performed the task using auditory stimuli presented at time intervals of Is, 3s and 5s, for 60 seconds in each trial. After each trial, observers responded their subjective psychological state during the trial. The results showed that subjective. responses of "arousal", "activity", "time pressure" and "anxiety" increased and that PD fluctuations spectra tended to shift to lower frequency (LF) when time interval of auditory stimuli was shorter. Moreover, significant correlations were observed between the ratio of lower frequency components to higher components (LF/HF) of PD fluctuations and "time pressure" or "anxiety", and between the peak frequency of PD fluctuations spectra and "time pressure" or "irritation". However PD mean was significantly correlated only with "arousal". These results indicate that LF/HF of PD fluctuations and the peak frequency of PD fluctuations spectra will be effective evaluation indices for mental stress.

We investigated the relationship between pupil diameter and psychological state during task execution using auditory stimuli. Pupil diameter was monitored and recorded by means of infrared video camera, while observers performed the task using auditory stimuli presented at time intervals of 1 s, 2 s and 3 s, for 60 seconds in each trial. After each trial, observers responded their subjective psychological state during the trial. The results show that subjective responses of "activity", "time pressure" and "anxiety" were increased, and the mean pupil diameter during 60 seconds period was also increased, when time interval of auditory stimuli were short.

(Summary) We measured thresholds for detecting stimulus displacement across saccade for various size of visual field. Our results show that thresholds decrease with increase of the visual field size when stimulus shifts in the same direction as saccade. On the contrary, when stimulus shifts in the opposite direction as saccade, thresholds increase with increase of the visual field size.

Haruki Mizushina and Keiji Uchikawa : Effects of visual field size on displacement detection across saccade, The Technical Report on the Institute of Image Information and Television Engineers, Vol.25, No.29, 91-96, Mar. 2001. (Summary) It has been shown in our previous research that thresholds of displacement detection across saccade in a whole visual field were different from those in a restrict visual field. There is a question whether this difference may depend on the presence of cue of absolute location(frame)within the visual field or the presence of pattern stimulus in the peripheral visual field. In this study, we carried out experiments to answer this question. The results indicate that an frame has an effect of suppressing threshold elevation and a tendency of thresholds depends on presence of stimulus pattern in a peripheral visual field.
