Description

Rendering device for stereoscopic scent scene and method for presenting stereo odor scene

In order to make the scene more realistic, while the film and television works are playing, some scent is released to the theater to enhance the viewer's sense of substitution.

CN200410064774.7 discloses a method for releasing electronic odors such as televisions and movies, and a system thereof. The technical solution combines the olfactory signal with the original visual and auditory signals when producing programs such as television, movies, video games, and computer software. By controlling the circuit board to operate a group of control valves, opening or closing a corresponding group of scent cans with different types of odors, releasing odors of the same type as the film, game, other film and television programs, and the same odor type, Then the fan is sent into the space. This scent release system simply releases different odors according to the picture, the experience is not real enough, and the spatial attributes of the odor are not considered. Existing odor presentation methods, on the one hand, have significant limitations in spatial reproduction that limit the vividness of their induced olfactory experience. On the other hand, the appearance of the three-dimensional scent has certain animal models and the support of the human neural basis. Insects, fish, and rodents can rely on the concentration of the bilateral antennae or olfactory epithelium to make the space of the odor source. Positioning. For rodents, the anterior olfactory nucleus may be critically involved in this process, and information exchange between the cerebral hemispheres on both sides plays an important role in stereo olfactory perception.

1. The present invention stores odors of different odor sources in different odor tanks, the odor sources are stored in a liquid, solid or gaseous form, and the control valve control system controls the odor scene by controlling the switch control of the scent control valve group. The taste, and adjust the odor concentration outputted in the scent reservoir through the odor concentration control valve so that the odor concentration of the right nasal cavity and the left nasal cavity are the same or different, and the concentration ratio allows the subject to experience the nasal cavity on the left and right sides. The difference in olfactory stimuli stimulated by different concentrations of odor can cause different electrical nerve activity of the olfactory epithelium on the nasal side of the wearer and the downstream olfactory bulb. Through the integration of the anterior olfactory nucleus, a stereoscopic olfactory perception with spatial information is generated.

2. The present invention can make the scent bring a three-dimensional olfactory feeling by constructing scenes from different odor sources, and cooperate with the image to enhance the stereoscopic experience and enhance the authenticity and vividness of the experience of the experience of movies, games and the like. Interesting. The integration of olfactory stereo information with other sensory information across the sensory channel increases the perceived processing depth of the depicted object.

3. Using the principle of the present invention to carry out a simulation experiment, the data shows that when the optical flow is used to simulate the visual input of the self-moving orientation, the difference in the odor concentration on both sides of the nose can effectively affect the subject's perception of the orientation, ie: The perceived self-movement orientation is biased toward the side with a higher odor concentration. This effect occurs under the olfactory consciousness level. For a olfactory substance that does not stimulate the trigeminal nerve, the subject cannot clearly say that the left and right sides smell a higher concentration of odor. However, his spatial orientation still remains Significant and systematic shifting to the high-concentration odor input side, to some extent, ruled out the potential for differential reactions caused by trigeminal nerve stimulation, which supports the validity of the design principle.

Experimental example:

First, the visual task

All experiments used a unified optical flow stimuli orientation judgment task, requiring the subjects to make a button judgment on their own motion orientation (left or right) as soon as possible while ensuring the correct rate. The optical flow stimulation consists of 1,800 outwardly diverging white spots, which simulates the change of visual stimuli on the retina when moving forward. It can effectively provide clues to its own motion. The simulated forward speed of the optical flow used in the experiment is 5m/s, there is a white gaze cross in the center of the light flow. In the experiment, the uniformity of the spot motion is 0.75, and the heading angle simulated by the optical flow stimulus is exponential sampling, which is 0°, 0.5°, 1°, and 2° horizontally to the left or right. The light flow stimulation is presented for a maximum of 500 ms. During the presentation, once the subject responded, the optical flow stimulus disappeared. The light flow stimulus is presented on a Dell curved display with a 34-inch black background. The display is 80cm wide and 34cm high with a screen resolution of 1366*768. The experimental process is shown in Figure 11.

Second, the olfactory stimulus

The olfactory stimuli are different concentrations of rose odor (p-ethyl alcohol solution dissolved in propylene glycol solvent, Phenethyl Alcohol, PEA, pure olfactory stimulation, inactive trigeminal nervous system), divided into eight conditions:

1. 5% on the left side, 0% v/v (volume ratio) PEA solution on the right side;

2. 0% on the left side, 5% v/v PEA solution on the right side;

3. 4% on the left side, 1% v/v PEA solution on the right side;

4. 1% on the left side, 4% v/v PEA solution on the right side;

5. 3% left, 2% v/v PEA solution on the right;

6. 2% on the left side, 3% v/v PEA solution on the right side;

7. Bilateral 2.5% v/v PEA solution;

8. Bilateral 0% v/v PEA solution.

Among them,

conditions

1 and 2 are high concentration ratios (100% difference),

conditions

3 and 4 are medium concentration ratios (75% difference),

conditions

5 and 6 are low concentration ratios (33.3% difference), and

conditions

7 and 8 are baselines. (the difference is 0%). For all odor conditions containing PEA, the physical sum of the inputs of the bilateral odors is equal. On the one hand, it is ensured that in the different odor settings, the total amount of odor inhalation of the subject is basically the same. On the other hand, under this concentration setting, the subject feels that the odor intensity is in an appropriate state and does not feel too strong or Too weak. The way the odor is presented is shown in Figure 2.

Third, the experimental participants

A total of 108 participants participated in the experiment. All the subjects were right-handed, with normal sense of smell, no smoking, no cold, no symptoms of rhinitis, normal vision or corrected vision, and no mental illness. among them:

1. 24 people completed high concentration ratio inter-group experiments, using high concentration

ratio odor conditions

1, 2, and

baseline conditions

7, 8;

2. 24 people completed the medium-to-concentration ratio experiment, using the medium concentration

ratio odor conditions

3, 4, and the baseline condition 7;

3. 24 people completed the low concentration ratio inter-group experiment, using low concentration

ratio odor conditions

5, 6, and baseline conditions 7;

4. 36 people completed the in-group experiment using all high concentration ratios, medium concentration ratios, low concentration ratios, and baseline odor conditions.

Fourth, the experimental process

In each trial, a cross-spot point of 250 ms was first presented, followed by a 500 ms optical flow stimulus. During the presentation process, once the subject responds, the optical flow stimulus disappears and the display maintains a black screen state for 1000 ms, entering the next trial (as shown in Figure 11). In the inter-group experiments, each group of experiments contained 70 trials, with no rest in each group; in the intra-group experiments, each group consisted of 75 trials with two 30-40 s rest in between. The same condition odor was always heard during the experiment.

During the completion of a set of experiments, the subject sat 57cm in front of the display, the chin was fixed, keeping the head still, watching the cross gaze point to reduce eye movement; the odor presenting device (as shown in Figure 2) was placed in front of the nose, nose cover The top tip is located in the nose, the test is inhaled by the nose, the mouth exhales, and does not pay attention to the smell itself; attention is focused on the visual task, and according to the stimulation of the light flow presented on the screen, it is as accurate as possible to judge whether it is moving to the left or right. Move forward, right hand button reaction.

1. Before the formal experiment, the participants first performed an adaptive exercise of one set of experimental tasks (the consistency of the spot motion was 1), three sets of familiar exercises (the consistency of the spot motion was 0.75, the same as the formal experiment), and continuous Five nasal flow measurements (measured for double nasal respiratory flux).

2. In the formal experiment, the participants completed multiple sets of the above experimental tasks. The specific situation depends on the experimental content of the participation, ensuring that each odor condition is completed in 2 groups, and the experimental sequence of each group is random. In the inter-group experiment, after each half of the number of experiments, the subjects required two repeated evaluations of the concentration and the pleasing of the odor, and the evaluation order was randomly presented; while in the intra-group experiment, the subjects required two days to complete the experiment. Eight sets of experiments were completed every day, that is, each set of conditions was completed. In addition, the subjects were required to evaluate the concentration and the degree of pleasure of the scent after the group.

3. After the formal experiment, the subjects underwent the same nasal flux measurement.

4. After all the experiments are completed, each concentration is required to perform 10 concentration side determinations for each of the odors. The subject was asked to wear an eye mask to determine which side of the nose smelled more intense. Among them, a pair of concentration ratios are equivalent, and the high-concentration odors on the left and right sides are presented in an ABBA equilibrium order.

V. Experimental results

In inter-group experiments and intra-group experiments, we found that under moderate odor concentration ratio conditions, subjects can obtain spatial information of odors from odors with bilateral concentration ratios and affect individual's own kinesthetic perception. Specifically, when the optical flow stimulus itself does not provide direction information (ie, the deflection angle is 0°), compared with the high-concentration odor on the right side, the tester will notice more of the high-concentration odor on the left side. Moving to the left front, the statistical results were: t ₂₃ =2.771, p<0.05 between groups, p value means that the probability of making this conclusion is less than 5%, and the experiment in the group is t ₃₅ =3.547, p<0.005. If the changes produced by all angles are taken into consideration, the subjective equivalence points of the participants' perceived optical flow stimulation are obtained by fitting the psychophysical curve, that is, the bias angle of the optical flow stimulation when the subject is subjectively considered to be moving forward. It was also observed that when the subject smelled the high-concentration odor on the left side, it was considered that the visual stimuli were biased to the righter side, and then they thought that they were moving forward, indicating that they subjectively produced their own motion deviation consistent with the high-concentration odor side. The statistical results were: t ₂₃ = 2.694, p < 0.05 between groups; t ₃₅ = 4.425, p < 0.0001 in the group. In addition, we further examined whether the olfactory information can promote the perception of self-movement when the visual stimulus provides direction but the angle is small (±0.5°). It is found that the visual stimulus and the olfactory stimulus are in the same direction when compared with the inconsistency. The correct rate of self-perception is higher, and the statistical result is t ₅₉ =2.836, p<0.01. However, under the conditions of high concentration ratio and low concentration ratio, there is only a similar trend, and the effect is not obvious. In addition, on the conscious level, under the three odor concentration ratio gradient conditions, the subjects could not judge which side is more odor; the possibility of differential reaction caused by trigeminal nerve stimulation was excluded.

It is worth noting that the above phenomenon occurs only when the odor concentration ratio on both sides of the nose is within a certain range. If the concentration ratio is too high (such as: one side has obvious odor and the other side is not), or the concentration ratio is too low (for example, the concentration ratio on both sides is less than 3:2), it can not effectively produce stereoscopic sense and influence Visual orientation perception. This also explains why some previous studies have reached inconsistent conclusions and resolved the academic controversy.

The high, medium and low concentration values of different odor sources depend on the specific odor. Among them, the medium concentration is suitable to be clear and moderate, and the high and low concentrations are based on medium concentration, and the concentration ratio is about 4:1.

In addition, without generating airflow through the air pump, by making different types of odor media, such as odor cream, scent pill, scent scent, etc., and controlling the concentration ratio, the purpose of stereoscopic scent scene presentation can also be achieved, and the patent should also be covered. In the category.

It is apparent that the above-described embodiments are merely illustrative of the examples, and are not intended to limit the embodiments.

Obvious changes or variations resulting therefrom are still within the scope of the invention.
