Description

Stereoscopic display system and stereoscopic display method

The present invention relates to the field of stereoscopic display, and particularly relates to a stereoscopic display system and method for reducing dizziness.

Virtual Reality (VR) is the use of computer simulation to generate a virtual world in a three-dimensional space, providing users with a simulation of vision and other senses, making users feel as if they are immersed in the environment, and can observe the three-dimensional space in real time without restriction Things. However, the current virtual reality technology still has many problems to be overcome, and the user's dizziness is one of the most important problems. In past studies, many reasons may cause users to experience dizziness when using virtual reality devices, and different users may have different causes of dizziness.

For example, when the eyes see that the picture is moving but the body does not feel it is moving, it may cause sensory inconsistency and cause dizziness; due to the latency of the picture, the rotation time during the head movement The time difference between the actual change time of the screen may also cause dizziness; the interpupillary distance (IPD) of each user is different, so the pupil center, lens center and screen center may not be available when the user uses the virtual reality device On the same line, the ghosting phenomenon causes dizziness; when the depth of field in the virtual reality screen is different from the user's perception, it may also cause dizziness.

It can be seen that the possible causes of dizziness in virtual reality cannot be summarized, and the related issues of dizziness resolution are also the focus of research by those skilled in the art.

In view of this, the present invention provides a stereoscopic display system and a stereoscopic display method, which can solve the problem of dizziness caused by most reasons by stimulating the user's advanced center.

The stereoscopic display system of the embodiment of the present invention includes a stereoscopic display, a wearable device, and a processor. The stereoscopic display is used to display stereoscopic dynamic images. Wearable devices are used to generate physical stimulation. The processor is coupled to the wearable device and the stereo display for dizziness solution. Solutions for dizziness include lifting the physical stimulus produced by the wearable device.

The stereoscopic display method of the embodiment of the present invention includes the following steps: displaying a stereoscopic dynamic image; and performing a dizziness solution, wherein the dizziness solution includes raising a physical stimulus generated by a wearable device.

Based on the above, the three-dimensional display system and the three-dimensional display method proposed by the embodiments of the present invention utilize physical stimulation generated by the wearable device to stimulate the user's advanced center to reduce the user's dizziness. Accordingly, the dizziness caused by most causes can be solved.

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

According to research, the main cause of dizziness when riding in a car or a boat is that the brain’s expectations of the external situation are inconsistent with the information received from the senses, resulting in uncomfortable consequences. In order to maintain balance, the brain combines data from many sources, including vision, touch, and inner ear balance. In particular, the inner ear is particularly important for detecting angular and linear displacement. For example, when the car turns to the right, the inner ears of the passengers in the rear seat will feel the changes in the right turn, but the vision is not as good as the front-seat driver can detect the changes in the scene when turning right. When the two kinds of information are inconsistent, it may cause brain data The confusion in the library led to motion sickness. The vestibular nervous system in the inner ear belongs to the low-level center and will be inhibited by the high-level center. If the mind is in a state of high tension or high concentration while driving, and the high-level center is in a state of high excitement, it will have an inhibitory effect on the vestibular nervous system. Combining the above factors is the main reason for driving without motion sickness.

In the stereoscopic display system and method of the embodiment of the present invention, when the user may be dizzy, the wearable device is used to generate physical stimulation to make the mind more nervous or concentrated, so as to reduce the dizziness. The following will describe it in detail with the diagram.

Please refer to FIG. 1, the stereoscopic display system 100 includes a processor 110, a wearable device 130 and a stereoscopic display 150. In some embodiments, the stereoscopic display system 100 is, for example, a Virtual Reality (VR) system for displaying stereoscopic dynamic images. However, the present invention does not limit the specific structure and implementation of the stereoscopic display system 100 here, and those with ordinary knowledge in the technical field should implement the stereoscopic display system 100 based on knowledge such as virtual reality.

The processor 110 can be used to send display signals to the stereoscopic display 150 to display stereoscopic dynamic images through the stereoscopic display 150. In addition, the processor 110 is further used to solve the dizziness, and perform appropriate operations to slow down the dizziness when the user may or does experience dizziness.

Specifically, the physical stimulus generated by the wearable device 130 is a stimulus that can be sensed by the sensory receiver of the human body, such as pain, temperature, touch, or pressure. In some embodiments, the wearable device 130 can be implemented as a helmet, a wrist brace, or clothing, etc., to generate electrical, temperature, or pressure and other physical stimuli, and the present invention is not limited thereto. In particular, as described in the previous paragraph, when the user's concentration or tension is increased due to physical stimulation, the dizziness can be reduced or avoided.

The stereo display 150 is coupled to the processor 110, and can receive a display signal from the processor 110 to display a stereo dynamic image. In some embodiments, the stereoscopic display 150 can be implemented as a head-mounted display for providing two images with parallax to the eyes of the user, respectively. However, the present invention is not limited to this. Those skilled in the art can implement the stereo display 150 according to their knowledge of stereo display.

FIG. 2 shows a flowchart of a stereoscopic display method according to an embodiment of the invention. Referring to FIG. 2, in step S110, the processor 110 sends a display signal to the stereo display 150, and the stereo display 150 displays the stereo dynamic image according to the received display signal. Subsequently, in step S120, the processor 110 determines the dizzy state. Finally, in step S130, the processor 110 will perform a dizziness solution based on the dizziness state determined by it, including controlling the physical stimulation generated by the wearable device 130.

Specifically, the dizziness state refers to the dizziness that the user does or may occur when viewing a three-dimensional dynamic image. In some embodiments, the stereoscopic display system 100 is further provided with a physiological detector (not shown), which is coupled to the processor 110 and used to obtain the physiological signal of the user when the stereoscopic display 150 displays the stereoscopic dynamic image, and process The device 110 can determine the dizziness state according to the physiological signal, for example. For example, the physiological detector may be a brain wave detector, a blood oxygen concentration detector, etc. The invention is not limited thereto. In some embodiments, the processor 110 may further predict whether the stereoscopic dynamic image displayed by the stereoscopic display 150 may cause the user to dizzy to determine the dizziness state, for example, directly based on the content of the display signal. For example, when the video content of the stereoscopic dynamic image changes or the frequency of view switching is higher, the user is more likely to be dizzy. When the processor 110 determines that dizziness is indeed or likely to occur when the user is watching a three-dimensional dynamic image, it can perform dizziness solutions by enhancing the physical stimulation generated by the wearable device 130 to improve the user's concentration. Reduce the user's dizziness.

It is worth mentioning that the embodiment of the present invention is not used to limit the dizziness solution performed by the processor 110. In other embodiments, the dizziness solution may include more methods and steps to reduce dizziness. The following examples will illustrate the stereoscopic display system and the stereoscopic display method proposed by the present invention.

FIG. 3 is a schematic block diagram of a stereoscopic display system according to an embodiment of the invention. 3, the three-dimensional display system 200 includes a processor 210, a blood oxygen concentration detector 220, a pressure wrist 230, and a three-dimensional display 250. The blood oxygen concentration detector 220, the pressure wrist 230 and the three-dimensional display 250 are all coupled Connected to the processor 210. The processor 210 and the stereoscopic display 250 are similar to the processor 110 and the stereoscopic display 150 in the embodiment of FIG. 1, so they will not be repeated here.

The blood oxygen concentration detector 220 is used to detect the blood oxygen concentration of the user when the three-dimensional display 250 displays a three-dimensional dynamic image to obtain a blood oxygen concentration signal. In detail, when the human body suffers from dizziness, heatstroke and other conditions, the brain will be hypoxic, and the blood oxygen concentration will drop significantly at this time. Therefore, the blood oxygen concentration signal helps the processor 210 determine the dizziness state.

The pressure brace 230 includes a controller 231, an air pump 233, and a pressure sensor 235. The air pump 233 and the pressure sensor 235 are both coupled to the controller 231, and the controller 231 is coupled to the processor 210. In some embodiments, the pressure wristband 230 is implemented in a manner similar to an arm or wrist sphygmomanometer, for putting it on the user's arm or wrist, and the pressure wristband 230 is inflated by the air pump 233 therein. It expands and squeezes the user's arm or wrist to provide pressure stimulation. For example, the processor 210 may send a control signal to the controller 231 to adjust the inflation or deflation of the air pump 233. When the air pump 233 is inflated, the pressure stimulation provided by the pressure cuff 230 will increase, and when the air pump 233 is deflated, the pressure stimulation provided by the pressure cuff 230 will be weakened. In some embodiments, the pressure sensor 235 is used to detect the pressure stimulus provided by the pressure cuff 230 to obtain the pressure value. In some embodiments, the blood oxygen concentration detector 220 can be integrated into the pressure cuff 230 when implemented, and coupled to the processor 210 through the controller 231, but the invention is not limited thereto.

4 shows a flowchart of a stereoscopic display method according to an embodiment of the invention. 4, in step S210, the processor 210 sends a display signal to the three-dimensional display 250, and the three-dimensional display 250 displays the three-dimensional dynamic image according to the received display signal, and the blood oxygen concentration detector 220 during display Will get the blood oxygen concentration signal. In step S220, the processor 210 determines whether the user's blood oxygen concentration is greater than a preset threshold according to the blood oxygen concentration signal.

In some embodiments, the preset threshold is a fixed value preset by the stereoscopic display system 200, for example, it is set to the blood oxygen concentration of an average person when dizziness occurs, such as 80%. In some embodiments, the processor 210, for example, starts to collect the blood oxygen concentration signal of the user after the stereoscopic display system 200 is turned on, and obtains the signal of the previous specific time (for example, the previous minute, the first three minutes, or other specific time). The average value of blood oxygen concentration, and then multiply this average value by a specific ratio (for example, 0.8) as the preset threshold. However, the present invention does not limit the specific setting method of the preset threshold.

If the processor 210 determines in step S220 that the blood oxygen concentration of the user is greater than the preset threshold, which indicates that the user may be dizzy, then it proceeds to steps S240 and S250 to perform dizziness solutions.

In step S240, the processor 210 sends a control signal to the controller 231 to command the air pump 233 to inflate, so as to increase the pressure stimulation provided by the pressure cuff 230, so as to reduce the user's dizziness. In some embodiments, the processor 210 determines when to stop the inflation air pump 233 according to the pressure value obtained by the pressure sensor 235.

In step S250, the processor 210 changes the content of the three-dimensional dynamic image displayed on the three-dimensional display 250 to provide physical stimulation while providing psychological pressure to the user to improve the user's concentration and tension, so as to reduce dizziness. Dizzy condition.

FIG. 5 is a schematic diagram of a three-dimensional dynamic image in an embodiment of the invention. In some embodiments, the stereoscopic dynamic image STIMG includes the fixed-point image Fx. The fixed-point image Fx is, for example, a nose or an arm, which can provide a fixed reference point for the user and has a certain degree of dizziness avoidance effect.

In some embodiments, the processor 210 modifies the stereoscopic dynamic image STIMG according to the pressure value obtained by the pressure sensor 235, for example, the arm or nose as the fixed-point image Fx expands as the pressure value increases. In some embodiments, the processor 210 may, for example, cause the non-fixed-point image in the stereoscopic dynamic image STIMG to expand as the pressure value increases. According to this, it is possible to increase the tension of the user and reduce dizziness.

On the other hand, according to medical research, blue images can give people a sense of relaxation, while red images can give people a sense of anxiety or tension. Therefore, in some embodiments, the processor 210, for example, filters the green component image and the blue component image of the 3D dynamic image, and retains the red component image of the 3D dynamic image for display. Accordingly, it is also possible to increase the user's tension and reduce dizziness.

If the processor 210 determines in step S220 that the blood oxygen concentration of the user is not greater than the preset threshold, it means that the user may not be dizzy or the dizziness has been relieved, and then proceed to step S230 to end the dizziness solution. For example, the deflation air pump 233 returns to the original state or restores a three-dimensional dynamic image.

In summary, the three-dimensional display system and the three-dimensional display method proposed by the embodiments of the present invention utilize physical stimulation generated by the wearable device to stimulate the user's advanced center to reduce the user's dizziness. Accordingly, the dizziness caused by most causes can be solved. In some embodiments, the wearable device is used as a pressure wristband to provide users with different pressure stimulations through inflation and deflation. In addition, some embodiments further add corresponding abnormal conditions to the three-dimensional dynamic image according to the pressure stimulation provided by the wearable device, so as to simultaneously give the user physical and psychological pressure, which can increase tension and further reduce dizziness.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make slight changes and modifications without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be subject to those defined by the attached patent scope.
