Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display and information presentation method using eye movement, and more particularly, to a display and information presentation method using saccade (impulsive eye movement). For example, the information presentation method according to the present invention is expected to be used in a parasite human, which is a wearing system that works as a symbiotic information subject.

[0002]

2. Description of the Related Art Conventionally, information is presented by moving a light spot group. Specifically, there is known a method of presenting information such as "inspection" or "stop" by shaking a signal light provided with a light point group by hand.

[0003] The present invention focuses on eye movement and presents information, and is different from the conventional one.
Eye movements (saccades) are used in medical fields such as, for example, brain disease examinations, but there is no technology for presenting information focusing on eye movements.

[0004]

SUMMARY OF THE INVENTION The present invention has been made based on a completely new idea that has not been achieved before.
It is an object of the present invention to provide a simple and versatile information presentation method by focusing on human eye movements, particularly fast and temporally stable eye movements called saccades.

[0005]

The technical means employed in the present invention includes a gazing point, a target, and a light spot disposed between the gazing point and the target. The present invention is characterized in that eye movement is induced from the target to the target, and the light spot is emitted in accordance with the eye movement to present information. Preferably, the light spot is a light spot group including a plurality of light spots, and more preferably, the light spot group is a single light spot row. Then, information can be presented by changing the light emission pattern of the light spot group with time according to eye movement.

When the light spot moves at a certain speed or more as shown in FIG. 1 (a), its trajectory looks like a continuous line due to an afterimage. On the contrary, as shown in FIG. When the eyeball moves at a speed higher than a certain speed, a line can be seen due to the same afterimage effect. The present invention utilizes this fact. As shown in FIG. 2A, information such as characters and symbols can be presented by moving the light spots in a line and moving the light emission pattern of the light spot train with time during the movement. . Therefore, by using the principle of FIG. 1B, by changing the light emission pattern of the light spot sequence with time during the movement of the eyeball, characters,
It is possible to present information such as symbols (FIG. 2)
(B)).

[0007] The fixation point and the target are preferably light spots. The gazing point, the index, and the light spot sequence are, in one preferable mode, LEDs.
, But is not limited thereto, and may be appropriately adopted from other known light sources.

The arrangement of the light spot groups is not limited and need not necessarily be arranged in a straight line. However, in one most preferred embodiment, the light point groups are a single light spot row and are continuous vertically. It has multiple lines. If the number of light spots is one, control of the light spots constituting the light spot row is easier than control of the light spots of the light spot row of a plurality of rows. Out of the way. Further, in the present invention, the information having one light spot is not excluded, but the perceived information is a broken line or a straight line, so that the information amount is small.

[0009] In one preferred embodiment, the eye movement (saccade) is triggered by first illuminating the point of interest, then stopping the illuminating of the point of interest and causing the optotype to emit light. In one preferred embodiment, the timing of the stop of the light emission at the fixation point and the timing of the light emission of the optotype are set to some extent (200 m
s). Therefore, the expression “stop the gazing point and emit the optotype” includes stopping the illuminating of the gazing point and then causing the optotype to emit light. It does not exclude what you do).

One of the great advantages of the present invention is that information can be presented with fewer light points than the spatially required number of display points. That is, to present the information as shown in FIG. 17, 25 light spots are usually required. According to the present invention, similar information can be presented by, for example, horizontally moving a five-row, one-column light spot column (five light spots). Therefore, according to the present invention, it is possible to reduce the size of the device, and it can be realized if there are two light spots and one light spot row, and can use existing resources and have versatility. It is possible to selectively present information that only the person who has caused eye movement can present information.

DESCRIPTION OF THE PREFERRED EMBODIMENTS [Overview of Information Presenting Apparatus and Method]
The basic configuration of the present invention will be described. As shown in FIG. 3A, the apparatus according to the present invention has a gazing point, an optotype, and a light spot array disposed between the gazing point and the optotype. Employs a single light spot sequence consisting of three (three rows) light spots that are continuous in the vertical direction. FIG. 18 is a schematic view of an experimental apparatus, in which a panel 4 is mounted on a central portion of a substrate 5 in the left-right direction, and a plurality of light spots 3 are arranged on the panel 4 in the weft direction. A gazing point 1 and a target 2 using LEDs are arranged on the substrate 5 so as to sandwich the panel 4. Wiring (not shown) is provided for each of the gazing point 1, the target 2, and the light spot 3, and the light emission timing of each point is controlled by an IC (not shown). In the experiment, only one vertical light spot array at the center of the panel was used. In the embodiment, the gazing point and the optotype are arranged in the left-right direction. However, the arrangement of the gazing point and the optotype is not limited to this. May be provided. In order to present information using eye movements, eye movements are induced on the information presenting side, and a sequence of light spots is emitted at the timing to present the information. In addition, since high-speed eye movement is required to cause an afterimage due to eye movement, a saccade (movement speed of 300 to 500 deg / sec), which is a high-speed movement component of tracking eye movement, is required.
trigger c).

In practice, as shown in FIG. 3 (a), first, the gazing point is illuminated to draw attention to the gazing point. Then, the gazing point is erased and the target is illuminated. By doing so, the gaze shifts from the point of gaze to the target, inducing a saccade. A sequence of light spots is emitted during the saccade to present information as shown in FIG.

FIG. 4 is a time chart showing the timing of the gaze point / target and the movement of the eyeball. The thick solid line represents the time period during which the gaze point / target is shining, and the dotted line represents the movement of the eyeball. First, the gazing point is shining, and the eyeball is facing the direction of the gazing point. Next, the fixation point disappears and the target shines. At this time, the eyeball does not start moving with respect to the target at the moment the target shines, but starts moving after a certain time (latency). While the eyeball starts to move and exceeds a certain speed, the light spot train is changed over time during the time indicated by the arrow in FIG. 4 to present information. Normally, when a saccade with a viewing angle of 10 degrees occurs, about 20 ms to 30 ms can be used for information presentation.

In the method according to the present invention, while the eyeball is rotating, the light spot is illuminated and changed to present information, and accordingly, the timing of illuminating the light spot train in accordance with the eyeball movement is determined. It becomes important. Assuming that the time required for the saccade is constant, it is necessary to induce a saccade in which the latency from the time when the optotype shines to the time when the eyeball starts to move is temporally stable. In other words, in order to present information stably and with good reproducibility, the more stable the time from the presentation of a stimulus to the occurrence of a saccade, it is clear when the light spot should be illuminated. The fact that the timing of flashing the dots is stable means that stable information presentation is possible.

[Type of Saccade] In the method according to the present invention, the saccade is induced by sequentially illuminating the point of interest and the target, but some saccades have different characteristics such as latency, maximum speed, and gain. Types exist. The types of saccades that are triggered differ depending on the point of gaze and the timing at which the target is illuminated. FIG. 5 shows the main types of saccades and the light emission timings of typical gazing points and optotypes that induce the saccades.

As a main saccade, an expectation saccade (FIG. 5) generated by predicting a position where an optotype appears in advance.
(A)), a saccade generated in the visual guidance consciously raised from a state in which both the gazing point and the target are lit (FIG. 5)
(B)), the saccade that the indicator is illuminated and the indicator is guided by the disappearance of the gazing point (FIG. 5 (c)), and the express saccade where the indicator shines after a certain period of time after the gazing point disappears (FIG. 5C). 5 (d)).

In the expectation saccade, since the position where the visual target appears is predicted in advance, the latency (in this case, the time after the gazing point disappears) varies as short as 20 ms to 80 ms. The saccades generated in the visual guidance have a latency of 150 ms to 20
0ms, saccade out of visual guidance is 150m latency
In about s to 200 ms, the maximum speed is faster than the saccade generated in the visual guidance, and the gain is large. The express saccade has a latency of around 100 ms and is shorter than the above two saccades.

It is known that express saccades have the most stable latency over time among them. In particular, the latency is most stable under the condition that the interval between the point of gaze disappears and the optotype glowing is 200 ms.
Express saccades were induced at 0 ms. Further, it is known that the express saccade has a more stable latency by repeating.

[Brightness of gazing point / target] The timing of light emission of the gazing point / target is 200 ms from when the gazing point disappears to when the target shines. However, this does not always induce an express saccade. No, the brightness of the gazing point,
The frequency varies depending on the size and the like. Therefore, an experiment was conducted to examine the relationship between the brightness of the fixation point / target and the frequency of triggering the express saccade. The gazing point and the brightness of the target were changed, and the frequency of occurrence of express saccades was examined.

FIG. 6 shows an outline of the experimental conditions. The experiment was performed in a dark room with a brightness of 0.02 cd / m ² , and the subject sat down so that the eyeball of one eye was located at a position 45 cm from the gazing point, and caused a saccade with one eye. The distance between the fixation point and the target was 8 cm, and the viewing angle was 10 degrees. This is because there are many saccades seen daily. LEDs were used for presenting the fixation point, the optotype, and the light spot sequence, respectively. The size of the fixation point and the target is 1.
3 degrees, the brightness is bright (0.8 cd / m ² ),
Medium (0.3 cd / m ² ), dark (0.1 cd / m ² )
The experiment was performed in three different combinations of nine brightness levels. The size of each light spot in the light spot row is 0.
25 degrees and the brightness was 14 cd / m ² ).

FIG. 7 shows a time chart of the experiment. The gaze point is light, and the subject turns his gaze to the gaze point. Next, the gazing point disappears, and after 200 ms, one of the right and left optotypes glows randomly. The randomization was used to prevent the occurrence of expected saccades due to repeated experiments.

A light point sequence of 3 rows and 1 column is arranged between the point of interest and the right target, and for 40 ms to 100 ms after the right target shines.
One light spot is turned on, two light spots are turned on for 100 ms to 160 ms, and three light spots are turned on for 160 ms to 220 ms. This is a latency of 4 if you can see the afterimage of the line at position 1.
A 0-100 ms anticipation saccade has occurred.
ms saccade when it is seen in the third position, it is a visual inducible regular saccade with a latency of 160 ms to 220 ms. 50 trials were performed with each combination of brightness.

FIG. 8 shows the experimental results of one of the subjects. It can be seen that the darker the gaze point, the higher the frequency of express saccades. This suggests that if the fixation point is too bright, the disappearance of the fixation point itself may trigger the expectation saccade. Also, there is no difference in the frequency of occurrence of express saccades due to fluctuations in the brightness of the target. Other subjects show a similar tendency. In view of this experiment, it was found that, in order to induce express saccades at a high frequency, the point of gaze that is not too bright will induce more express saccades.

[Information Presenting Ability] An experiment was conducted to examine the information presenting ability of the present method to determine how much information can be presented in one saccade when the present method is used for information presentation. Here, the information presentation ability means how many pixels of information can be presented in space at a time when this method is used. Specifically, as shown in FIG. The number X of pixels that can be displayed can be calculated by X = T / tm, where T is the time available for information presentation in the saccade, and tm is the minimum presentation time for presenting one pixel in space. Since the time T available for information presentation during the saccade is known, the minimum presentation time tm was determined by experiment.

The experimental conditions will be described. The experiment was performed in the same dark room as the brightness experiment, and the same LED was used. The positional relationship between the subject, the gazing point, and the target was the same as in FIG. 6, except that the distance between the subject and the gazing point was 92 cm, and the distance between the gazing point and the target was 16 cm. The viewing angle from the fixation point to the target is 10
Degrees. The gazing point and optotype brightness is 0.1 cd /
m ² , and the target was 0.8 cd / m ² . As the light spot array, only the center light spot in FIG. 6 was used. The width of the light spot row is 1mm and 0.5m
m, and two viewing angles of 0.0625 ° and 0.03125 ° were prepared.

An experimental method will be described. FIG. 10 shows a time chart of the timings at which the gazing point, the target, and the light spot sequence shine in this experiment. First, the gazing point flashes, and the subject turns his or her gaze to the gazing point. Next, the fixation point disappears, and after 200 ms, either the right or left optotype glows randomly. Then, while the saccade is occurring from the gazing point toward the target, the light spot at the center of the light spot row in FIG. 10 blinks at a specific time interval. Then, a broken line is perceived as indicated by the arrow in FIG. Therefore, when the interval at which the light spot sequence blinks is gradually reduced, the interval between the broken lines is gradually reduced, and finally a straight line is perceived. Since the time interval at the boundary between the dashed line and the straight line can be considered as the minimum unit time of information presentation, it was determined how small the interval at which the light spot blinks before the straight line was perceived.
Specifically, we started with a pattern of 2 ms on and 2 ms off, reduced the off time in 0.1 ms steps, and identified the boundaries of when to perceive a straight line by the up and down method. However, the width of the light spot array was prepared in two ways, 0.0625 degrees and 0.03125 degrees in viewing angle, and the eyesight was about 0.6 for the subject and 1.
The experiment was performed in two groups of about 0, and the experiment was performed under each combination and four conditions.

The experimental results will be described. The boundary between the straight line and the broken line specified by the up-down method differs depending on the width of the light spot sequence and the visual acuity. Table 1 shows the minimum light-off time at which a broken line can be perceived.

[Table 1] The second row is the result when the width of the light spot column is 0.0625 degrees.Subjects with a visual acuity of about 0.6 perceive a broken line until the turn-off time is 0.4 ms, and subjects with a visual acuity of about 1.0 show a broken line until the turn-off time is 0.3 ms. Perceived. The third row shows the results when the width of the light spot column is 0.03125 degrees.A subject with a visual acuity of about 0.6 perceives a broken line until the turn-off time is 0.3 ms. Perceived.

A dashed line was perceived even when the width of the light spot array was small and the visual acuity was improved, even during a shorter extinguishing time. When a saccade with a viewing angle of 10 degrees occurs, about 20 ms can be used for information presentation, so the number of pixels X that can be displayed in the horizontal direction is
X = 20 (m when the width of the light spot row is 0.03125 degrees and the eyesight is about 1.0
s) /0.2 (ms / pixel) = 100 pixels, width of light spot row 0.062
X = 20 (ms) /0.4 (ms / pixel) for 5 degrees and about 0.6 vision
= About 50 pixels. The number of pixels that can be displayed in the vertical direction can be adjusted depending on how many light spot columns are arranged.In this study, information was presented using a maximum of seven light spot rows, but it was sufficient. Met. Considering this information presentation method as a display, it is considered that a display with an information presentation capability of about 7 pixels in height and 50 to 100 pixels in width is set in this experiment.

Next, in this experiment, the physical conditions under which the broken line is no longer perceived will be considered. As shown on the left side of FIG. 11, assuming that the width of the light spot sequence is A (degree), the turning-off time is tm (second), and the speed of the eye movement while the light is off is V (degree / second), Moves V × tm over the retina while the lights are off. At that time, a gap having a size of d = V × tm−A physically exists, but when the gap is visually recognized, a broken line is perceived. This gap is smaller than the portion where the dashed line exists, and checking whether this gap is visible is considered to be equivalent to obtaining the visual acuity of the minimum readable threshold measured by the Landolt ring. Table 2 shows the specific eyesight.

[Table 2] The first row in Table 2 is the extinction time tm, and the second row is the viewing angle α at which the light spot sequence moves on the retina during the extinction time.
Since the viewing angle that can be used for presenting information in a saccade with a viewing angle of 10 degrees is about 5 degrees, when the time during which information can be presented during the saccade is T, it can be obtained by α = 5 degrees × tm / T. The third row is a physically existing gap d, which is a value obtained by subtracting the width A (0.0625 degrees) of the light spot sequence from α. The fourth line is a visual acuity for visually recognizing the gap d. Without this visual acuity, the gap cannot be visually recognized. The fifth and sixth rows show the gaps and visual acuity at different widths (0.03125 degrees) of different light spot columns. Further, the negative values in the third and fifth rows indicate that d = V × tm−A <0 as shown in the right side of FIG. When a broken line cannot be perceived.

Focusing on the relationship between the light-off time and the visual acuity in Table 2, when the width of the light spot row is 0.0625 degrees (the third and fourth rows), if the visual acuity is about 0.6, the light-off time is 0.4 ms, and the gap is 0.4 ms. When the visual acuity is about 1.0, the gap is physically visible up to 0.4 ms or 0.3 ms. When the width of the light spot row is 0.03125 degrees (line 5 and line 6), when the eyesight is 0.6, the gap is physically visible up to 0.3 ms when the extinction time is 0.3 ms. The gap is physically visible up to 0.2 ms. This is in good agreement with the experimental results in Table 1, and it was found that physical constraints are dominant when considering the information presentation ability of the present method. Although there is a report that the visual acuity decreases during the saccade, it does not seem that the visual afterglow is noticeably reduced.

In this experiment, the experiment was conducted by preparing two types of widths of the light spot arrays.
The minimum displacement (veriosity) is 2 "(0.00056 degrees), at which the displacement between the two straight lines can be distinguished, and the minimum gap size that can be visually recognized is up to the limit of human vision, 2.0. The minimum gap that can be visually recognized by a person with an eyesight of 2.0 is d = 0.00833 degrees,
When tm is obtained by substituting the time T = 20 ms and the horizontal width A of light spot array A = 0.00056 into the relational expression of d = 5 degrees × tm / TA (saccade with a viewing angle of 10 degrees). , Tm
= 0.0356 ms, and at that time, the number of pixels that can be displayed in the horizontal direction X = T / tm = 562 pixels.

That is, theoretically, it was found that about 10% of two-dimensional information of a display having a resolution of VGA (640 pixels in the horizontal direction) can be presented by one saccade of 10 degrees. However, in order to present information to more people, the visual acuity of the presented person should be set to about 0.6, so that the number of pixels that can be displayed is smaller than the above calculation. Next, when the same calculation is performed with a visual acuity of 0.6, the visual acuity of the vernier scale also changes, and the width A of the light spot sequence becomes 0.00185 degrees, and tm =
Calculated as 0.119ms. At this time, the number of pixels X that can be displayed in the horizontal direction is X = 168 pixels. With this more general condition setting, it is possible to present 2D information of about 1/4 of VGA, and when presenting alphanumeric characters, if the width of one alphanumeric character is 5 pixels, about 30 characters Can be presented.
However, when presenting characters such as alphanumeric characters, even if a large amount of information can be physically presented, the number of characters that can be recognized in one afterimage is limited, and it is necessary to consider the limitations related to that. is there.

A specific design theory will be described. In the case of actually presenting information using this method, how to determine each parameter (timing of the sequence of light spots, size of saccade, distance between gazing point / optotype, etc.) Here are some guidelines for design based on the discussions. First, considering the relationship between the speed of eye movement during the saccade and the elapsed time, FIG.
It becomes like the graph of. This graph shows the movement speed of the eyeball on the vertical axis and the elapsed time on the horizontal axis, and shows the time from the start of the saccade to the end of the saccade.
The time at which saccades began to occur was t = 0. As shown in the graph, the movement speed of the eyeball increases after the start of the saccade, reaches a certain peak, starts to decrease, and becomes 0 at the end of the saccade. In order to present information by this method, an afterimage must occur due to eye movement, so information can be presented only while the movement speed of the eyeball exceeds a certain speed (vertical axis V _{0 in} the graph of FIG. 12). Becomes Saccade is the time for the first time information can be presented eyeball speed from happening and t _1, peaked eyeball speed, the time the information presented is impossible to t _2. The time T that can be used for information presentation is T = t ₂ −t ₁ . At this time, if the minimum unit time for presenting one pixel in the space is tm, the number of pixels that can be displayed in the horizontal direction X = T /
tm. Contrary to the above discussion, when presenting information using the present information presenting method, if the number of pixels X of the information to be presented is determined, the time T required to present the information is determined, The size θ of the saccade at that time is also determined. Further, as shown in FIG. 13, the distance D between the gazing point and the optotype is expressed as D = L × tan θ using the distance L between the gazing point and the information presenter and the size θ of the saccade.

As a specific design example, the visual acuity is set to 0.
Consider presenting 15 alphanumeric characters to about 6 people. Assuming that the horizontal direction of one character is 5 pixels, the number of horizontal pixels required for display X = 15 (characters) × 5 (pixels /
Since (character) = 75 pixels, if the minimum unit time tm for presenting one pixel is 0.4 ms, the time required for information presentation is T = 75 (pixel) × 0.4 (ms / pixel) = 30 ms. However, the value of tm = 0.4 ms indicates that in the experiment in the previous section, the eyesight of the subject was about 0.6 and the width of the light spot train was 0.0625.
The value in degrees. Next, the time available for information presentation
30ms or more.

The saccade viewing angle θ is determined. Table 3 shows a correspondence table in which the relationship between the size of the saccade and the time available for information presentation was examined in a preliminary experiment.

[Table 3] According to the table, the viewing angle θ of the saccade in which the time available for information presentation is 30 ms or more is 20 degrees. When the viewing angle θ of the saccade is determined, the positional relationship between the gazing point and the target is also determined. When the distance L between the eyeball and the gazing point is 1 m, the distance D between the gazing point and the target is D = L × tan θ = 36 cm. FIG. 14 left shows a specific configuration image diagram. FIG. 14 right shows a luminous timing chart of the gazing point, the target, and the light spot sequence at that time. First, the gazing point is turned on, and the gaze is directed to the gazing point. Next, the optotype is turned on 200 ms after the gazing point is turned off, and an express saccade having a stable latency of about 100 ms is induced. The eyeball starts saccade toward the target after a latency of about 100 ms. The saccade with a viewing angle of 20 degrees is about 80 ms, and the time during which information can be presented during the saccade is about 30 ms. During the 30 ms when the information can be presented, the light spot sequence is turned on in a pattern of scanning characters from the end in 0.4 ms steps to present the characters (FIG. 14).
Between the right arrows). However, in the case of FIG. 14, since the eyeball is moving to the right, the light spot sequence is turned on in such a manner that the character is scanned from the right.

In this specification, a simple and versatile information presentation method has been proposed by focusing on the fast and temporally stable eye movement called Express Saccade. When this information presentation method was used, it was found that the amount of information that could be presented in one saccade was about 1/4 of VGA display and about 30 alphanumeric characters. In addition, focusing on two points, the timing of the gaze point and the optotype, and the brightness of the gaze point and the optotype, as conditions for performing stable information presentation using this method, the stable Conditions were specified. Next, we showed the design guidelines on how to design the presentation system when presenting information using this method.

As an application example utilizing the features of the present method, there are several directions. First, since the present method can present information if there are two light spots and one light spot sequence, a device using this method can be expected to be reduced in size, and as shown in FIG. Applicable to devices. When mounted on a wearable device, if eye movements can be easily measured, it is possible to reliably present information accordingly.

Second, since the present method can present information even in a space without devices, even in a town where people usually live, light spots are placed at both ends of buildings, and light spot trains are placed near one light spot. It is also possible to present information in the air by arranging it. However, as discussed in the previous section, when using this method outdoors, it is possible to present information more effectively when used in a slightly dark environment such as in the evening to night.

Third, since light spots and light spot arrays are already built into some device such as a computer power supply, using this method, information can be presented by combining these existing resources. Becomes

Fourth, since the present method utilizes the human eye movement, only the person who has caused the eye movement can see information, and there is selectivity of information presentation. Considering this feature, application to ubiquitous computing or the like that requires selective presentation of a large amount of information is also conceivable. The amount of information conveyed using this method is about several English words at a time, but it is possible to present the state of each unit in ubiquitous computing. FIG. 16 shows an application example of presenting individual information (author, age, price, etc.) in ubiquitous computing, specifically, in an exhibition in an art museum or the like. In the future, as more and more information is transmitted, it will be important to present the information only to those who want to see it, rather than dropping all of the information.
