Description

Technical Field

[0001] This invention relates to the field of space orientation training technology, and in particular to a space orientation training system and method for simulating extraterrestrial survival activities. Background Technology

[0002] Spatial orientation is a fundamental ability of the human sensory system to determine the spatial relationship between oneself and the environment. 80% of spatial orientation sensory information comes from vision, 10% from the inner ear's balance system, and the remaining 10% from receptor information in muscles, tendons, and joints, as well as pressure distribution in the calcaneus. Disorientation in the human body typically involves decreased sensory sensitivity, perceptual errors, insufficient sensory compensation, perceptual conflict, delayed information integration, postural adjustments, or orientation errors.

[0003] Humanity will face challenges in extraterrestrial survival during deep space exploration missions, such as shortened line of sight relative to Earth's gravity in low gravity, frequent falls, and misjudgments of distance, crater edges, and slope angles. The mechanisms underlying these spatial orientation problems are currently unclear, but they are related to changes in the human center of gravity caused by clothing, low gravity environments, and the surface features of extraterrestrial planets.

[0004] Virtual reality technology, using algorithms to create simulated 3D alien planet scenes, combined with weight reduction to simulate low gravity training methods, has been applied in training techniques. However, this training method suffers from weak proprioceptive stimulation realism, resulting in poor training effects and low efficiency. Furthermore, since low gravity simulations typically involve restraint gear, it restricts shoulder and waist movement, affecting the naturalness of training operations.

[0028] This application provides a spatial orientation training system for simulating extraterrestrial survival activities, such as... Figure 1 As shown, it includes: Computer equipment 1 is used to construct a complete virtual reality scene of the surface of an extraterrestrial planet; in the specific implementation process, remote sensing imagery can be used to construct a virtual reality scene covering 100 km. A 100 km wide-area extraterrestrial planet surface scene was constructed based on decimeter-level terrain and imagery data acquired by a navigation camera. This localized, detailed scene was then registered with the textures of the larger-area terrain scene to achieve seamless integration. A 1.2 km high-resolution virtual terrain scene was also created. The distance is 1.2 km, with a smooth band of 0.2 km at the junction, thus creating a visually realistic effect for simulating extraterrestrial surface activity in this application.

[0029] In the environmental simulation area, for the terrain features 5 of a local target virtual reality scene within the overall virtual reality scene, predetermined terrain materials are used to simulate and lay out the terrain to obtain a physical terrain that matches the target virtual reality scene; in specific implementation, for the local target virtual reality scene (e.g., 3.2m) within the overall virtual reality scene... For an 8m target virtual scene, this application utilizes chemically foamed polyurethane with a Young's modulus of 0.075 MPa and employs stereoscopic laser engraving technology to create a 3.2m model that perfectly corresponds to the target virtual display scene. The 8m model simulates the surface of a real three-dimensional alien planet with a carving precision of 1mm, and the terrain has a good sense of realism when stepped on.

[0030] Several positioning devices 2 are deployed around the environment simulation area and are respectively connected to the computer for communication. They are used to determine the first location information of the target training object wearing the head-mounted device in the environment simulation area in real time, and send the first location information to the computer device so that the computer device can determine the virtual reality scene to be displayed in real time from the target virtual reality scene based on each first location information. In this embodiment, there may be 4 positioning devices, which are respectively deployed at the vertex positions of 4 in the rectangular environment simulation area.

[0031] The head-mounted device 3 is communicatively connected to the computer device and is used to receive and display the virtual reality scene to be displayed sent by the computer device.

[0032] In this embodiment, the computer device is further used to pre-establish the coordinate transformation relationship between the target virtual reality scene and the environment simulation area; the computer device is specifically used to: receive first location information sent by each positioning device, determine the second location information of the target training object in the target virtual reality scene based on the first location information and the coordinate transformation relationship, and determine the virtual reality scene to be displayed based on the second location information.

[0033] In the specific implementation process, the terrain material is foamed polyurethane; the physical landform is obtained based on foamed polyurethane and through three-dimensional laser engraving.

[0034] In this embodiment, the environmental simulation area also includes props depicting the surface of an extraterrestrial planet. The spatial orientation training system in this embodiment also includes a vestibular electrical stimulation module / vestibular electrical stimulation device 4, used to output electrical stimulation signals to provide vestibular electrical stimulation to the target trainee. In this embodiment, to address the limitations imposed on the human body's shoulder, waist, and back movements by the restraint system used in weight-loss simulations of low gravity, this application employs a bilateral bipolar electrical stimulation method of the mastoid process to simulate the postural instability caused by gravity transitions when landing on an extraterrestrial planet, thus providing the effect of low gravity. The vestibular electrical stimulation mode adjusts the amplitude ratio of 0.16Hz, 0.33Hz, 0.43Hz, and 0.61Hz sine waves according to each individual's vestibular electrical stimulation threshold, forming a sine harmonic with a peak frequency of approximately 0.2Hz and a peak-to-peak amplitude not exceeding 5 millivolts. This generates vestibular electrical stimulation below or above the threshold, stimulating the subject during training, with continuous stimulation time not exceeding 10 minutes.

[0035] In this embodiment, the computer device is also used to generate and output training tasks so that trainees can perform corresponding training actions based on the training tasks.

[0036] In this embodiment, the spatial orientation training system also includes: a portable electrocardiogram monitor 6, a blood pressure monitor 7, and a thermometer 8; The portable electrocardiogram monitor, blood pressure monitor, and thermometer are respectively connected to the computer device for communication. The portable electrocardiogram (ECG) monitor is used to: detect the electrical activity signal of the heart of the target trainee when performing a training task, and transmit the heart electrical activity signal to the computer device; specifically, the portable ECG monitor can communicate with the computer device through a predetermined data processing device, which is equipped with existing methods / programs / supporting software for parsing and exporting heart electrical activity signals, that is, the heart electrical activity signal can be parsed, exported and transmitted to the computer device through the supporting software.

[0037] The blood pressure monitor is used to: detect the blood pressure information of the target trainee when performing training tasks, and send the blood pressure information to the computer device; in this embodiment, manual recording can also be used, that is, the blood pressure is recorded manually and transmitted to the computer device.

[0038] The thermometer is used to detect the body temperature of the target trainee when performing training tasks and send the body temperature to the computer device. In this embodiment, manual recording can also be used, that is, the body temperature is recorded manually and transmitted to the computer device.

[0039] The computer device is also used to: determine training results and adjust training tasks based on the cardiac electrical activity signal, blood pressure information, and body temperature.

[0040] In this embodiment, the spatial orientation training system further includes an electromyography (EMG) recorder 9, which is communicatively connected to the computer device. The electromyography (EMG) recorder is used to: detect the electromyographic activity signals of the target trainee when performing training tasks, and transmit the electromyographic activity signals to the computer device; specifically, the electromyographic activity signals can be communicated with the computer device through a predetermined data processing device, which is equipped with existing methods / programs / supporting software for parsing and exporting the electromyographic activity signals, that is, the electromyographic activity signals can be parsed, exported and transmitted to the computer device through the supporting software.

[0041] The computer device is also used to: determine training results and adjust training tasks based on the muscle electrical activity signals.

[0042] In this embodiment, the spatial orientation training system further includes: a foot stress insole detection device 10, which is communicatively connected to the computer equipment; The foot stress insole detection device is used to: detect the pressure information of the sole of the target trainee when performing training tasks, and transmit the pressure information to the computer device; specifically, the pressure information can be communicated with the computer device through a predetermined data processing device, which is equipped with existing methods / programs / supporting software for parsing and exporting pressure information, that is, the pressure information can be parsed and exported by the supporting software and transmitted to the computer device.

[0043] The computer device is also used to: determine training results and adjust training tasks based on the pressure information.

[0044] In this embodiment, the spatial orientation training system further includes a motion capture subsystem, which includes several shooting devices 11, each of which is set around the environmental simulation area. Each of the aforementioned shooting devices is communicatively connected to the aforementioned computer equipment; Each of the aforementioned shooting devices is used to: capture motion images of the target training subject while performing a training task, and send the motion images to the computer device; The computer device is also used to: determine the action training results and adjust the training task based on each of the action images. Specifically, the computer device is equipped with supporting image processing software, which enables the determination of action training results based on each action image using the supporting image processing software.

[0045] In this embodiment, by utilizing chemically foamed polyurethane combined with sculpting technology to simulate the features of an extraterrestrial surface, the simulation effect becomes more realistic. This solves the problem in existing technologies that only simulate the visual effect of a three-dimensional extraterrestrial surface without corresponding proprioceptive stimulation of the lower limbs and ankles. It also addresses the issue of using materials such as sand to create complex extraterrestrial surface terrain, which prevents the effective integration of virtual reality effects—that is, the inability to match the terrain in the virtual reality scene with the terrain in the actual simulated physical scene. In this application, through experimental comparison of the differences in human biomechanical characteristics during vertical jumps on the simulated physical surface and hard terrain, and by comparing the biomechanical characteristics of vertical jumps on sand versus hard terrain, it was found that the physical surface possesses biomechanical characteristics that are largely similar to but slightly different from those of vertical jumps on sand. The human body adjusts to this physical interface and forms a new biomechanical strategy, demonstrating that the physical surface realistically simulates the "both soft and hard" nature of a real extraterrestrial surface in terms of human biomechanics. Therefore, the simulated three-dimensional real physical terrain established by this invention can provide realistic proprioceptive simulation stimulation for spatial orientation training for extraterrestrial survival activities.

[0046] In this embodiment, by constructing a complete virtual reality scene of the surface of an extraterrestrial planet, the virtual reality scene to be displayed can be quickly and accurately determined from the target virtual reality scene in the overall virtual reality environment based on the first location information collected by each positioning device. The head-mounted device can then quickly and accurately display the corresponding virtual reality scene. Furthermore, when the trainee moves in real time within the simulated environment area, the training system can quickly and accurately match the corresponding virtual scene and render it, achieving precise linkage between virtual and reality and avoiding ineffective training. By simulating and setting up the environment area as a physical terrain scene that matches the virtual reality scene, the virtual display scene can be highly simulated. Combined with physical terrain, this allows the trainee to have a good sense of realism in stepping on the ground, enhancing the immersion and realism during training, promoting the formation of core competencies such as spatial orientation and emergency response, thus improving training efficiency and avoiding ineffective training.

[0047] The proposed space orientation training system for simulating extraterrestrial survival activities provides comprehensive simulation of extraterrestrial planetary surface scenes from visual, vestibular, and proprioceptive perspectives. The space orientation tasks cover typical movements and mission scenarios, enabling real-time evaluation of training effectiveness and retrospective technical assessment after training. It can provide more natural and realistic virtual training scenarios and more comprehensive and practical training support for ground-based space orientation training for deep space explorers to survive extraterrestrial life.

[0048] Another embodiment of this application provides a spatial orientation training method for simulating extraterrestrial survival activities, including the following steps: The head-mounted device is worn on the head of the target training subject; Each positioning device detects the target training object's first location information in the environmental simulation area in real time and sends the first location information to the computer device; The computer device determines the virtual reality scene to be displayed in real time from the pre-constructed target virtual reality scene based on the first location information and sends it to the head-mounted device; The head-mounted device displays the virtual reality scene to be displayed in real time; The target trainees perform training tasks in an environment simulation zone based on a virtual reality scene displayed by a head-mounted device to conduct spatial orientation training.

[0049] In practice, trainees wear head-mounted devices that display virtual scenes before training begins. Training tasks include both dynamic and static tasks. Dynamic tasks involve trainees training on a simulated three-dimensional physical exoplanet surface. Through visual scenes (virtual scenes matching the simulated surface of a real exoplanet, large-area virtual scenes), vestibular stimulation (no stimulation, stimulation below or above the threshold), and task settings (human orientation and movement, handheld controls combined with human orientation and movement), trainees complete various spatial orientation tasks. These tasks primarily include sampling, walking, two-legged jumping, alternating single-leg vertical jumping, entering and exiting craters, avoiding craters, climbing platforms, exploring hills, searching for targets, completing planned delivery and retrieval of items, and returning to the starting point.

[0050] Static training tasks refer to the following: the trainee stands on a plane (ground, physical exoplanet surface, platform), vestibular stimulation (no, <threshold stimulation, ≥threshold stimulation), and visual presentation speed (adaptation speed, appropriate acceleration) to set training levels. The trainee uses a controller to complete the tasks in a large-scale exoplanet surface scene. The right controller button moves forward or backward within the field of view, while the left controller controls the rotation direction and angle. The tasks include crouching sampling, orientation positioning, orientation exploration, obstacle avoidance (avoiding meteorite craters), exploration (exploring large and deep meteorite craters), remote exploration (reaching a designated location), and path planning (self-setting markers and selecting a path back to the starting point).

[0051] In other words, in the training method of this application, the trainee can wear a head-mounted device to perform dynamic training tasks in an environmental simulation area. In addition, the trainee can also wear a head-mounted device to perform static training tasks in a non-environmental simulation area.

[0052] In this application, the assessment of training effectiveness includes a physiological and behavioral evaluation module, which is divided into an evaluation of the effectiveness of the current training session and a specific evaluation of the effectiveness of the current training cycle. The evaluation indicators for the current training session are divided into three categories: physiological indicators: heart rate, blood pressure, and forehead temperature before and after training; training implementation indicators: training completion time, disorientation during training (loss of direction within the specified time and inability to return to the starting point), and number of postural imbalances during training; and self-assessment: dizziness self-assessment and postural control confidence self-assessment. If, in each training session, the heart rate increases by >30 bpm, systolic blood pressure increases by 25 mmHg, diastolic blood pressure increases by 15 mmHg, or forehead temperature decreases and shows no significant recovery after 5 minutes of rest, the training difficulty or duration needs to be adjusted and reduced. If the task cannot be completed within the specified training time, or if disorientation or a high frequency of imbalances occurs during training, the training frequency needs to be increased. If the training completion time is too short (≤5 minutes), and all indicators and self-assessment are normal, the training difficulty needs to be increased.

[0053] This training effectiveness evaluation assesses specific techniques by comparing relevant physiological and behavioral indicators recorded at the first and last training sessions. The evaluation includes static and dynamic tests. Static tests involve standing and squatting on a platform; dynamic tests involve walking, in-situ bipedal vertical jumps, and alternating single-leg vertical jumps on a simulated three-dimensional real-world planetary surface. Evaluation indicators include lower limb joint (knee and ankle) range of motion, root mean square electromyography (EMG) of the bilateral tibialis anterior and gastrocnemius muscles, median EMG frequency, and percentage of peak to average plantar force. The evaluation method is a comparison of indicators before and after training. Based on existing research data, the rate of change for all indicators is calculated as: [(post-training indicator value - pre-training indicator value) / pre-training indicator value]. 100% should not exceed 30%. If the root mean square electromyography (RMSE) is significantly enhanced while the median frequency of the electromyography decreases to ≤60Hz, and there is significant muscle fatigue in the lower limbs, the training cycle duration needs to be adjusted in the next training cycle; if the range of motion of the lower limb joints (knee, ankle) increases or decreases significantly, the key points of the relevant movements need to be paid attention to in the next training cycle; if the percentage change between the peak force and the average force on the sole of the foot is too large, the stability of the foot and ankle needs to be assessed.

[0054] This application addresses the issues of weak realism in proprioceptive stimulation and conceptually limited training evaluation methods in current virtual reality training. It utilizes chemically foamed polyurethane to create a three-dimensional, realistic simulation of an alien planet's terrain in a specific area of ​​a virtual scene, providing a good sense of stepping. Simultaneously, vestibular electrical stimulation can reconstruct approximately 50-90% of the human posture response when transitioning from a microgravity field to a gravitational field. By using vestibular electrical stimulation of the mastoid process to simulate the postural instability caused by changes in vestibular perception during activities on an alien planet's surface, the application effectively simulates the multi-sensory impacts of vision, vestibular sense, and proprioception during human activities on an alien planet's surface. Furthermore, the training tasks are designed to cover typical movement postures and operational tasks, enabling spatial orientation training. Through dynamic and continuous monitoring of behavioral and physiological responses, and based on experimental research results, relevant indicator evaluation limits are established to achieve immediate and technical evaluation of training effectiveness, thereby improving training efficiency.

[0055] This application enables the realistic simulation of perceptual changes related to extraterrestrial surface activities through multiple systems, including visual, proprioceptive, and vestibular stimulation. The spatial orientation training tasks cover dynamic and static typical tasks related to extraterrestrial surface activities, encompassing posture control, movement, and orientation judgment. During training, physiological and behavioral monitoring technologies are integrated to conduct technical evaluations of the training effect for each session and the entire training cycle. This provides a platform and technical support for the precise and detailed development of individualized training programs and ensures the safe and effective implementation of training. The system's functions cover both training and evaluation, demonstrating comprehensiveness and practicality, and providing a powerful platform and technical support for ground-based training in spatial orientation tasks related to extraterrestrial survival.
