Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of detection systems, and in particular relates to a VR device wearing comfort detection system. Background Art
[0002] Virtual Reality (VR), also known as spiritual environment technology or artificial environment, is a virtual world in three-dimensional space simulated by computer systems. It can provide users with simulations of vision, hearing, touch and other senses, allowing users to immerse themselves in the scene and observe things in three-dimensional space in a timely and unlimited manner. When the user moves, the computer can immediately perform complex calculations and transmit accurate three-dimensional space videos back to create a sense of presence. This technology integrates the latest developments in computer graphics, computer simulation, artificial intelligence, sensing, display and network parallel processing. It is a high-tech simulation system generated by computer technology. With the upgrading of products, users pay more attention to the comfort of products. In the current VR equipment development process, a large number of people need to be found to verify the wearing comfort, and then collect user feedback and perform structural modeling, which consumes a lot of manpower costs. At the same time, the subjective evaluation of the verification group is not objective and cannot give engineers an accurate modeling direction, resulting in engineers having to make multiple modeling modifications, which increases the product development cycle and time cost. Summary of the invention
[0003] The technical problem to be solved by the present invention is to provide a VR device wearing comfort detection system, which can conveniently and objectively obtain the wearing comfort of the product and provide guidance for engineers' modifications.
[0004] In order to solve the above technical problems, the technical solution of the present invention is:
[0005] A VR device wearing comfort detection system includes a processor, a plurality of pressure sensors electrically connected to the processor, and an electroencephalogram (EEG) acquisition device, wherein the pressure sensor is used to measure the pressure on a wearing part of a tester and send the pressure value to the processor, and the EEG acquisition device is used to collect EEG signals on the scalp surface of the wearing part of the tester and send the EEG signals to the processor, and the processor determines whether each of the pressure values is within a comfort range, and determines the pain value of the wearing part of the tester under the current pressure according to the EEG signals; the pressure sensors include a first pressure sensor for detecting the pressure on the wearing part of the tester in the horizontal direction, a second pressure sensor for detecting the pressure on the eyes of the tester in the vertical direction, and a third pressure sensor for detecting the pressure on the ears of the tester.
[0006] Furthermore, the first pressure sensors are dispersedly installed on the tester's head at positions inside the host and headband of the VR device.
[0007] Furthermore, the second pressure sensor is installed below the tester's eyes at a position on the lower edge of a main unit of the VR device.
[0008] Furthermore, the third pressure sensor is installed at a position where the test person's ear is located inside an earmuff of the VR device.
[0009] Furthermore, the third pressure sensors are dispersedly installed on the scalp area around the ear root, the inner part of the auricle, the outer part of the auricle and the ear root.
[0010] Furthermore, the pressure sensor is a patch type pressure sensor.
[0011] Furthermore, the EEG acquisition device includes an electrode cap module, an EEG control module and a signal transmission module. The electrode cap module stimulates the scalp of the test person to generate EEG signals and acquires the generated EEG signals. The EEG control module receives and converts the acquired EEG signals and sends them to the signal transmission module. The signal transmission module sends the converted EEG signals to the processor.
[0012] Furthermore, the electrode cap module includes a microcurrent stimulator and a dry electrode. The microcurrent stimulator outputs a stimulation current to act on the scalp of the test person to generate an electroencephalogram (EEG) signal. The dry electrode collects the electroencephalogram (EEG) signal fed back from the scalp of the test person and sends it to the EEG control module.
[0013] After adopting the above technical solution, the beneficial effects of the present invention are:
[0014] Since the VR device wearing comfort detection system of the present invention includes a processor, a plurality of pressure sensors electrically connected to the processor and an electroencephalogram acquisition device, the pressure sensor is used to measure the pressure at the wearing part of the test person and send the pressure value to the processor, the electroencephalogram acquisition device is used to collect the electroencephalogram signal on the scalp surface of the wearing part of the test person and send the electroencephalogram signal to the processor, the processor determines whether each pressure value is in a comfort range, and determines the pain value of the wearing part of the test person under the current pressure according to the electroencephalogram signal; the pressure sensor includes a first pressure sensor for detecting the pressure in the horizontal direction of the wearing part of the test person, a second pressure sensor for detecting the pressure in the vertical direction of the eyes of the test person, and a third pressure sensor for detecting the pressure on the ears of the test person, the design comprehensively judges the wearing comfort of the VR device by whether each pressure value is in the comfort range and the pain value, and the result is convenient and objective, which can avoid the situation where the test person's own sensory insensitivity causes pain after wearing for a long time, thereby providing guidance for engineers' modifications. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a structural schematic diagram of the VR device wearing comfort detection system of the present invention;
[0016] In the figure, 1-processor, 2-first pressure sensor, 3-second pressure sensor, 4-third pressure sensor, 5-EEG acquisition device, 6-electrode cap module, 7-microcurrent stimulator, 8-dry electrode, 9-EEG control module, 10-signal transmission module. DETAILED DESCRIPTION
[0017] The present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0018] The directions mentioned in this specification are based on those shown in the drawings and only represent relative positions, not absolute positions.
[0019] like Figure 1 As shown, the VR device wearing comfort detection system includes a processor 1, a plurality of pressure sensors electrically connected to the processor 1, and an EEG acquisition device 5. The pressure sensor is used to measure the pressure at the wearing part of the test person and send the pressure value to the processor 1. The EEG acquisition device 5 is used to collect the EEG signal of the scalp surface of the wearing part of the test person and send the EEG signal to the processor 1. The processor 1 determines whether each pressure value is in a comfort range, and determines the pain value of the wearing part of the test person under the current pressure according to the EEG signal.
[0020] like Figure 1 As shown, due to the large weight of the host itself, the host exerts a certain downward pressure on the skin around the user's eyes after the VR device is worn. In order to ensure the immersive effect of the VR device and prevent sound leakage, the earmuffs themselves also have a certain inward pressure. The skin around the eyes and ears is relatively fragile and needs to be distinguished from the skin in other parts of the head. The pressure sensor includes a first pressure sensor 2 for detecting the pressure on the test person's wearing part in the horizontal direction, a second pressure sensor 3 for detecting the pressure on the test person's eyes in the vertical direction, and a third pressure sensor 4 for detecting the pressure on the test person's ears.
[0021] Among them, the first pressure sensor 2 is dispersedly installed on the head of the tester, located inside the host and headband of the VR device, the second pressure sensor 3 is installed below the eyes of the tester, located at the lower edge of the host of the VR device, and the third pressure sensor 4 is installed on the ear of the tester, located inside the earmuff of the VR device. Specifically, the third pressure sensor 4 is dispersedly installed on the scalp around the ear root, the inner part of the auricle, the outer part of the auricle, and the ear root. The pressure sensor is a patch pressure sensor with a small size and light weight, which will not cause too much pressure on the tester.
[0022] Determining whether the pressure at each location of the wearing part is in a comfortable range, that is, determining whether the pressure at each location of the wearing part is uniform, specifically: calculating the first average value of the pressure values obtained by all first pressure sensors 2, and whether the difference between the pressure value of each first pressure sensor 2 and the first average value is less than the uniform threshold; calculating the second average value of the pressure values obtained by all second pressure sensors 3, and whether the difference between the pressure value of each second pressure sensor 3 and the second average value is less than the uniform threshold; if the difference between the pressure value of each first pressure sensor 2 and the first average value is less than the uniform threshold, and the difference between the pressure value of each second pressure sensor 3 and the second average value is less than the uniform threshold, the processor 1 determines that each pressure value at the wearing part is in a comfortable range. The above uniform threshold is specifically set by those skilled in the art based on experience.
[0023] Certain parts of the human head are more sensitive and may feel pain when under the same pressure as other parts, but the test person himself does not feel it much and cannot express it. Therefore, it is necessary to test the EEG signal. The technical personnel in this field will set the pain value specifically according to the degree of fluctuation of the EEG signal.
[0024] like Figure 1 As shown, the EEG acquisition device 5 includes an electrode cap module 6, an EEG control module 9 and a signal transmission module 10. The electrode cap module 6 stimulates the scalp of the tester to generate EEG signals and collects the generated EEG signals. The EEG control module 9 receives and converts the collected EEG signals and sends them to the signal transmission module 10. The signal transmission module 10 sends the converted EEG signals to the processor 1. Among them, the electrode cap module 6 includes a microcurrent stimulator 7 and a dry electrode 8. The microcurrent stimulator 7 outputs a stimulation current to act on the scalp of the tester to generate EEG signals. The dry electrode 8 collects the EEG signals fed back from the scalp of the tester and sends them to the EEG control module 9.
[0025] The VR device wearing comfort detection system of the present invention sends the pressure on the wearing part of the test person and the EEG signal on the scalp surface to the processor by setting up a plurality of pressure sensors and EEG acquisition devices. The processor determines whether each pressure value is in the comfort range and the pain value under the current pressure, and comprehensively determines the wearing comfort of the VR device. The result is convenient and objective, which can avoid the situation where the test person's own senses are insensitive and cause pain after wearing for a long time, thereby providing guidance for engineers' modifications.
[0026] Although the specific embodiments of the present invention are described above, those skilled in the art should understand that the described embodiments are only some embodiments of the present invention, rather than all embodiments, which are merely examples, and the protection scope of the present invention is defined by the claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and essence of the present invention and without any creative work, but these changes and modifications all fall within the protection scope of the present invention.
