Virtual Ocean Roaming System and Its Operation Method Based on Cognitive Interaction Technology

technical field

The invention belongs to the technical field of virtual ocean roaming. It relates to a virtual ocean roaming system based on cognitive interaction technology and an operation method thereof, and the application field is virtual life experiment and teaching.

Background technique

Currently popular virtual reality environment systems can be divided into the following categories: desktop type, helmet type, CAVE type, and Cybersphere type. These types of devices are used in different fields, but there are also problems with expensive, fragile, and lack of real-time interactive functions. Shortcomings.

The desktop system uses the display screen of an ordinary computer or a low-end workstation as a window for users to observe the virtual scene. This form has low cost, and because the display device is only a relatively small computer screen, the sense of immersion is poor.

The helmet-mounted system uses the helmet-mounted display to close the user's vision and hearing. Although the immersion is relatively strong, there are problems such as a strong sense of restraint, low resolution, and large distortion.

The main body of the CAVE is a room, and each wall, ceiling, and floor of the room are composed of large screens, and high-resolution projectors project images onto these screens. The CAVE style realizes a virtual environment with a large viewing angle, a panoramic view, and three-dimensional support for sharing by multiple people. However, participants are still confined to a limited and small space, limited by walls in the real world, and cannot walk a large distance.

The common problem in the above several forms is that the participants are either restricted in place or can only walk in a limited space. In the real world, people should be able to move in a wider space. In the application of the scene, when real people are required to participate in the interactive behavior in the virtual environment, this problem is more prominent, and it also restricts the application of virtual reality technology.

In order to overcome this problem, Warwick University in the United Kingdom cooperated with some British companies to develop a virtual environment system-cybersphere system. The cybersphere system uses a large hollow translucent sphere as a display device. The sphere can rotate freely when placed on a stand. The operator is inside the sphere and directly contacts the inner surface of the sphere to complete the function of free walking. The computer produces constantly changing images according to the operator's body movements, and projects them on the surface of the sphere through a projector, and the operator inside the sphere can see the stereoscopic images through the stereoscopic glasses worn. This form enables the operator to walk freely without distance limitation, but since the sphere is completely closed, the operator must communicate with the outside world (mainly interactive devices) through a wireless connection, and this kind of device cannot be directly connected in the market. It needs to be developed separately; the operator has to bear equipment such as power supply, which increases the burden; since the sphere has to bear the weight of the person and continuously rotate on a support, and needs to be projected on it, the requirements for material strength and optical performance are relatively high. High, so it is more difficult to make the sphere

Adjust the height of the horizontal console support 10 so that the operator's line of sight is completely covered by the spherical projection screen 9 surrounding his head. The simulated three-dimensional environment of the seabed and the immersive spherical projection screen generated by the virtual reality server 22 make people feel more comfortable. It seems to be in the colorful world of the ocean. The operator's legs can reciprocate up and down, driving the slide rods 3 and 6 of the simulated paddle to trigger the analog signals generated by the pressure sensors 24 and 25 located under the pistons, and the analog signals are converted into action commands of the three-dimensional scene through the data control server 18 It is transmitted to the virtual reality server 22 to control the movement of the three-dimensional scene in the spherical projection screen, giving the operator the feeling of controlling the movement of the body in the ocean. At the same time, the operator controls the five pressure sensors 27 on the horizontal console by changing the center of gravity of the body to transmit the signals to the data control server for processing, and the generated body posture control command controls the servo motors 11 and 16 of the three-dimensional motion instrument to work, realizing The operator's control of the three-dimensional posture of the body.

During the simulated diving process, the operator can interact with the virtual creatures in the three-dimensional environment. For example, the command to feed small fish is through the movement of the arm, and the three-dimensional sensor 2 installed on the arm is controlled to generate a signal and transmit it to the data control server. The data control server converts the arm sensor signal into the virtual hand control command of the virtual reality server, and the data control server transmits the motion signal to the virtual reality server, and the virtual reality server receives the motion control command of the virtual hand, and the virtual The arm will move and select the action type according to the operator's command, complete the control of the three-dimensional menu, and the feeding action of the virtual arm.

The advantage of the present invention is that it can generate a virtual marine environment with the nature of artificial life, and allow the operator to immerse in the virtual three-dimensional environment to interact with the artificial life. Compared with similar foreign products, the structure is simple and the operation is convenient , the cost is relatively low.
