[0002] During VR psychotherapy, the patient's physiological condition (such as heart rate) fluctuates significantly with the virtual environment. Therefore, VR psychotherapy systems typically rely on real-time monitoring of the patient's physiological condition to control virtual environment changes and regulate their emotions. This approach complicates virtual environment design and increases software development costs. Furthermore, regulating the patient's emotions solely through virtual environment changes can result in delayed or inefficient responses. Summary of the Invention

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] Example 1

[0028] This embodiment provides a VR psychotherapy system, which is a new treatment system that combines more effective biological response and feedback regulation and reduces dependence on software scenarios.

[0029] Specifically, if Figure 1 As shown, the new VR psychotherapy system includes a central control module and multiple VR working modules, which form an interactive group. Each VR working module group includes at least a VR head-mounted display component, a physiological monitoring component, and an interactive sensing component. In addition, existing VR working modules generally also include a VR interactive component.

[0030] Among them, the functions of the VR head display component, VR interaction component and physiological monitoring component are components currently possessed by market products and clinical equipment. The VR head display component is used to provide the treated individual with an immersive visual and / or auditory experience, generally a comprehensive visual-auditory experience. The VR interaction component is used to enable the interaction between the treated individual and the virtual environment. The physiological monitoring component is used to collect and provide feedback on the real-time physiological data of the treated individual. During the VR psychotherapy process, the physiological conditions (such as heart rate) of the treated individual will fluctuate greatly with the virtual scene. With the help of the physiological monitoring component, the VR psychotherapy system can control the changes in the virtual scene based on the real-time monitoring of the treated individual's physiological conditions, thereby regulating the treated individual's emotions.

[0031] Unlike existing technologies, this embodiment utilizes multiple groups of VR working modules equipped with interactive sensing components. These components detect physical contact between individuals being treated and generate physical contact signals. The central control module receives real-time physiological data collected by each group of VR working modules, dynamically generates and outputs interactive commands based on changes in real-time physiological data and preset physiological indicators, receives physical contact signals fed back by the interactive sensing components, and optimizes and adjusts the interactive commands based on changes in physical contact signals and real-time physiological data.

[0032] In addition to heart rate data, the real-time physiological data of the treated individual collected and fed back by the physiological monitoring component can also be skin conductance (GSR) or blood oxygen saturation. Generally, multiple data are monitored simultaneously. For example, in anxiety analysis, the integrated PPG heart rate sensor and GSR sensor can dynamically calculate the anxiety index through heart rate + GSR physiological data.

[0033] The interactive sensing component is suitable for using a wearable interactive sensing component, which is convenient for collecting physical interaction actions such as handshakes, shoulder leaning, hugging, etc. between different treatment individuals. These actions can quickly play a role in regulating the emotions of the treatment subjects.

[0034] like Figure 2 As shown, in order to introduce handshakes between treatment individuals into emotion regulation, this embodiment uses the interactive sensing component shown in the figure to detect hand contact between treatment individuals. The interactive sensing component is wearable and has electrodes (or magnetic sheets) set at the hand contact site. When two treatment individuals make contact between the two electrode sheets through a handshake action, a hand contact signal can be generated for capture by the central control module. The central control module receives the real-time physiological data collected by each group of VR working modules, dynamically generates and outputs interactive instructions based on changes in real-time physiological data and preset physiological indicators, receives physical contact signals fed back by the interactive sensing component, and optimizes and adjusts the interactive instructions based on changes in physical contact signals and real-time physiological data.

[0035] The "interaction instructions" here may at least include the start of interaction, the end of interaction, the duration of interaction, the frequency of interaction and / or the interaction cycle.

[0036] By providing pressure-sensitive sensors for the electrode sheets (or magnetic sheets) or other parts of the wearable interactive sensing component, the strength of physical contact between the treated individuals can also be detected, so that the "interactive instructions" can further include contact degree (force) instructions.

[0037] After the central control module dynamically generates interactive instructions, it can directly output interactive instructions to the selected treatment individual through VR visual prompts, VR auditory prompts, or visual and auditory prompts.

[0038] In this embodiment, the VR psychotherapy system uses a VR egg chair group as an interactive support device to provide interactive support between the treatment individuals of multiple groups of VR work modules. Each egg chair in the VR egg chair group has two swingable armrests, which are used to support the arms of the treatment individual and have left and right swing joints. The left and right swing joints obtain swinging freedom after being unlocked by the locking pins and are driven to swing left and right by the torque of the human forearm. Adjacent treatment individuals can conduct physical interaction based on the interactive instructions of the central control module during their respective VR psychotherapy. When a handshake interaction is required, the treatment individual can drive one or both sides of the swingable armrests closer to the forearm of the adjacent interaction party through the forearm torque after the locking pin of the swingable armrest is unlocked to reach the handshake distance. The VR egg chair group is preferably arranged in a ring with the end connected, so that an interactive closed loop can be formed without the need for staff to assist on both sides.

[0039] The present invention supports both independent treatment of each treatment individual and collaborative treatment of multiple individuals under interactive instruction control. The central control module can provide different preset physiological indicators for different treatment individuals in multiple groups of VR work modules. The preset physiological indicators of each treatment individual can be optimized through machine learning.

[0040] The present invention also supports adjusting the physiological data of the treated individual by changing and adjusting the virtual scene of the VR working module. In particular, when the preset physiological indicators of different treated individuals in the collaborative treatment individual group are relatively discrete or there are treated individuals with abnormal preset physiological indicators, the central control module can dynamically generate and / or optimize the adjustment of interactive instructions, and cooperate with the change adjustment of the virtual scene of one or more groups of VR working modules to ensure that the physiological data of each treated individual is maintained within the preset physiological indicator range.

[0041] Example 2

[0042] This embodiment is an application example. The VR psychotherapy system of Example 1 is used to treat a group of patients with social anxiety disorder, establish trust through physical interaction, and relieve anxiety.

[0043] The physiological monitoring component integrates a PPG heart rate sensor (accuracy ±1bpm) and a GSR sensor (resolution 0.01μS), which can be worn by the patient. Figure 2 The tactile feedback gloves (including pressure sensors) shown in the figure are used. The treatment individuals are divided into groups of four and sit in the circular VR egg chair group with swingable armrests in Example 1 for VR experience. The virtual scene is a simulated social cocktail scene. After the patients wear the device, they rest for 5 minutes, and the basal heart rate and GSR are recorded. The system sets the anxiety index AI safety threshold.

[0044] In this embodiment, the anxiety index AI is:

[0045] AI=0.6×[(HR-HRbase) / (HRmax-HRbase)]+0.4×[(GSR-GSRbase) / (GSRmax-GSRbase)]

[0046] HRmax and GSRmax are the preset safety thresholds for heart rate and GSR, and the AI ​​weight coefficient can be adjusted to adapt to other diseases.

[0047] Simulating a social drinking party scene, the virtual character is initially 3 meters away from the patient and gradually approaches. When it detects that one or more treatment individual AI exceeds the set threshold (for example, ≥0.5) as a sign of anxiety, the central control module triggers the interaction command of the adjacent treatment individual and gives the handshake command through VR auditory prompts. Figure 2 The gloves shown can have a built-in vibration element, which can be used to strengthen the handshake prompt by synchronously triggering the vibration of the vibration element in the glove. If the anxiety index of the treated individual changes significantly after the handshake (such as a decrease of AI ≥20% within 10 seconds), the interaction is judged to be effective, and the handshake time is extended to 30 seconds (or other set time). The handshake time, corresponding anxiety index change information and pressure average value in the process are recorded and used for optimizing and adjusting the interaction instructions in the next round to adapt to the dynamic change target of the anxiety index. The handshake data can be used to train the machine learning model and optimize the interaction strategy.

[0048] If a treatment subject participates in the interaction but the anxiety index does not change as expected, the system reduces the approach speed of the virtual character in the corresponding VR work module, and collaboratively controls the physiological data of the treatment subject. For specific treatment subjects with slow treatment effects, a step-by-step collaborative treatment method can be used to gradually change the corresponding preset physiological indicators.

[0049] Clinical tests show that compared with pure scene adjustment, the physical interaction of the present invention can speed up the relief of anxiety by nearly 40%, and the frequency of interaction in a group of four people per unit time reaches 15-18 times per hour.

[0050] In summary, the VR psychotherapy system provided by the present invention is a new type of treatment system that combines more effective biological response and feedback regulation and reduces dependence on software scenarios. It is an interactive treatment system based on multiple groups of VR working modules. By introducing real-time physical interaction of multiple individuals combined with physiological indicator feedback, more direct physiological state regulation is achieved. Moreover, the central control module in the present invention supports providing different preset physiological indicators for different treatment individuals in multiple groups of VR working modules. By dynamically generating and / or optimizing and adjusting interactive instructions, and coordinating changes in the virtual scenes of one or more groups of VR working modules, the physiological data of each treatment individual can be maintained within the preset physiological indicator range.

[0051] The above is only a preferred specific embodiment of the present invention. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
