[0023] This disclosure relates to a VR therapy system that integrates a cross-platform, VR and multi-sensory stimulation game therapy application for physical activity, cognitive training, mental health and other aspects. This disclosure refers to the application as SENSO.
[0024] SENSO utilizes game engines such as Unity 3D to create VR living scenarios, integrating multi-dimensional sensory experiences including sight, hearing, touch, and even smell. By comprehensively applying game mechanics, 3D modeling, and human-computer interaction technologies, SENSO provides an immersive virtual world for people with cognitive impairments, physical disabilities, and mental illnesses, allowing them to freely explore and interact with the virtual world, thereby obtaining a good gaming experience.
[0025] SENSO can include various forms of play therapy, such as:
[0026] 1) Nostalgia: It's like a nostalgic journey, allowing users to relive the good old days;
[0027] 2) Gardening: It allows users to enjoy the pleasures of rural life and experience the joy of planting and harvesting;
[0028] 3) Nature: It allows users to experience nature exploration and feel the virtual wonders of nature;
[0029] 4) Instrumental daily life activities: These allow users to operate tools in daily life and improve their self-care abilities.
[0030] SENSO can be flexibly deployed on multiple platforms and supports various user inputs. Whether it is a VR headset with a handheld controller, a desktop / laptop computer with motion capture equipment or gloves, or a tablet computer that supports multi-touch, it can meet the operating habits and needs of different users and achieve a personalized treatment experience.
[0031] SENSO can incorporate various sensory elements. In particular, it integrates olfactory element synchronization technology. Using this technology, olfactory elements are programmed to ensure that they can be released in real time in sync with the specific tasks in the VR scene, bringing users an unprecedented immersive sensory experience.
[0032] Figure 1 The present disclosure illustrates a VR therapy system architecture based on an embodiment of the present disclosure, showing hardware devices supporting SENSO and demonstrating the compatibility of SENSO applications across different platforms. Figure 1 As shown, hardware devices that support SENSO may include:
[0033] 1) VR headset
[0034] VR headsets, also known as head-mounted VR platforms, display received VR scenes through head-mounted displays. For example, the VR scene image can be displayed on two separate screens, and then projected onto the left and right eyes respectively, forming a three-dimensional image in front of the user's eyes.
[0035] One example of a VR headset is the Meta Quest 3. TM The Meta Quest 3 is a high-performance VR headset that leverages the powerful Unity game engine to easily deploy SENSO applications. The Meta Quest 3 can be equipped with two handheld controllers. These controllers, acting as human-computer interaction devices, collect user behavior data, such as button presses, and communicate with the VR host. The VR host then adjusts the VR scene and provides feedback to the user in response to this data. The handheld controllers support a rich set of gestures, such as grasping, triggering, and pinching, which can be used to control the content displayed in the VR headset, further enhancing the user's interactive experience. It's important to note that SENSO can be widely deployed on various VR and interactive devices, not just the Meta Quest 3.
[0036] 2) Desktop Platform
[0037] A desktop platform can serve as the processing core of a VR therapy system, i.e., a virtual reality host. This can be, for example, a desktop computer or laptop, supporting Windows or Linux operating systems. Utilizing the processing power of the central processing unit (CPU) of these computing devices, human-computer interaction can be achieved, responding to user input and generating corresponding outputs. The CPU can handle data processing, data acquisition and storage, and interactive data processing. It not only supports information processing and transmission but also has audio and video processing capabilities, supporting multitasking. It can generate virtual environments based on virtual environment data and drive dynamic changes within those environments.
[0038] Desktop platforms can also include motion capture devices, another type of human-computer interaction device, such as Ultraleap. TM Motion capture devices. Ultraleap is a high-precision motion capture device that accurately captures subtle finger movements, including clenching a fist, pinching, and opening the hand, providing users with an intuitive and precise gesture interaction experience. Motion capture devices can be standalone hand motion capture devices that track the entire hand by sensing bare hand movements or wearing motion capture gloves. An example of an Ultraleap device is the Leap Motion Controller 2.
[0039] 3) Tablet PC Platform:
[0040] Tablet platforms can be any touchscreen device with multi-touch capabilities, such as an iPad or iPhone. As another type of human-computer interaction device, tablet devices offer users flexible operation methods through multi-touch functionality, including single-click, double-click, pinch, and rotation, enabling SENSO applications to achieve smooth and intuitive interaction on mobile devices.
[0041] 4) Olfactory devices:
[0042] Olfactory devices are devices that provide olfactory perception responses; an example is the ScentRealm device. ScentRealm is a neck-worn olfactory device that incorporates multiple, for example, 12 different encapsulated scents. In the SENSO application, these scents are released in real-time, synchronized according to the needs of VR scenes, creating an immersive olfactory experience for the user.
[0043] The desktop platform can include an odor database that pre-stores various VR scenes and their corresponding odor information, establishing a mapping between odor information and VR scenes. When the desktop platform detects a VR scene, it retrieves the matching odor information from the database and passes it to the olfactory device. For example, if fruit appears in a virtual reality scene, the olfactory device generates the fruit's odor information. The olfactory device then releases the corresponding odor from its encapsulated odor database. This adds olfactory simulation to virtual reality, enhancing the sense of presence and user experience.
[0044] The development tools and environment for the VR therapy system disclosed herein may include:
[0045] 1) Unity Game Engine: As the core platform for SENSO application development, Unity provides a wealth of functional modules and efficient development tools, which can help developers quickly build and optimize VR applications.
[0046] 2) Visual Studio and C#: Using Visual Studio as the programming environment, combined with the powerful features of the C# language, can provide stable and efficient code editing, debugging, and performance optimization support for the development of SENSO applications.
[0047] The SENSO application is developed using the Unity game engine, combined with the C# programming language and a Visual Studio plugin. The Unity engine provides a powerful and versatile platform for creating immersive experiences in the SENSO application, allowing for easy deployment to VR devices such as the Meta Quest 3. Within the Unity environment, the game mechanics of the SENSO application are implemented through carefully crafted script sets. These script sets define in detail various game scenarios and interaction patterns used for healing. For example, a gardening-themed script set can define the behavioral logic and interaction methods of gardening activities within a gardening game scene, covering a wide range of gardening activities such as watering, harvesting fruit, and weeding.
[0048] 3) Game Object Creation Software: 3D game objects in the system can be created using 3D CAD design software. For example, in Autodesk Maya, realistic textures and materials can be assigned to the required 3D mesh models, and detailed model adjustments can be made. The finished product can then be seamlessly imported into Unity for further development.
[0049] 4) User Interface Design: 2DSprite images can be created using Adobe Illustrator, a vector graphics design software. These images can then be imported into Unity to build the user interface (GUI), adding intuitive and engaging visual elements to the SENSO application.
[0050] Table 1 Comparison of various treatment products
[0051]
[0052] SENSO applications differ significantly from traditional naturopathy, multi-sensory rooms, and other VR applications, as shown in Table 1. Its unique features are reflected in the following aspects:
[0053] 1) It provides a fully immersive VR content experience, integrating diverse VR scene simulations, including nostalgia, gardening, nature exploration, and practical daily life activities, bringing users a comprehensive sensory immersion;
[0054] 2) Supports a variety of user interaction methods. Whether it is the grip, trigger and pinch operation through the VR platform, the fist, pinch, pan and open hand gestures on the desktop platform, or the single click, double click, rotation and pinch touch operation on the tablet platform, a smooth interactive experience can be achieved.
[0055] 3) Featuring fully responsive, interactive game objects, allowing users to experience the unique charm of interactive multisensory therapy firsthand. Particularly noteworthy is the close synchronization between olfactory elements and VR content in the SENSO app, providing users with an unprecedented sensory fusion experience.
[0056] Figure 2 This illustration demonstrates user interaction with the system to trigger olfactory emission, depicting a scenario where a user triggers olfactory stimuli through interactive operations, and visually showcasing the synchronization mechanism between olfactory elements and VR content.
[0057] Users can browse and select VR scenes. In interactive areas, users can interact using eye contact or gestures. Taking gesture interaction as an example, if a fist-clenching motion is detected in the Unity virtual environment and its timer reaches the specified duration, it indicates that the gesture is complete, and corresponding olfactory stimulation can be applied based on this completed gesture.
[0058] The olfactory elements in the SENSO application are closely synchronized with VR content, offering several advantages: First, olfactory information can be processed directly to the cerebral cortex without filtering through the thalamus, and can be rapidly transmitted to key areas such as the hippocampus, limbic system, and amygdala, thereby regulating the autonomic nervous system and endocrine system more quickly and producing emotional effects such as relaxation, calmness, pleasure, or excitement. Second, the olfactory cortex pathway is closely connected to the hippocampus, which is responsible for memory, giving olfactory stimulation a unique advantage in enhancing memory. Furthermore, implicit memories related to smell are often relatively intact in patients with cognitive impairment, meaning that olfactory stimulation training may have a positive impact on their behavior or emotions. In fact, olfactory stimulation training has been shown to help alleviate symptoms of depression and can improve cognitive function to some extent in patients with cognitive impairment. For example, the widespread use of lavender oil in aromatherapy demonstrates its effectiveness in reducing agitation and aggression.
[0059] SENSO can leverage AI to enable multi-sensory play therapy, which can include visual, auditory, tactile, and olfactory sensory stimulation.
[0060] Figure 3 A nostalgic scene is shown as an embodiment of this disclosure. Figure 4A -E illustrates a gardening scenario according to an embodiment of this disclosure. Figure 5A -D illustrates a natural scenario of an embodiment of this disclosure. Figure 6 This illustration depicts a practical everyday activity scenario based on an embodiment of the present disclosure. That is, Figures 3 to 6 The four game themes of the SENSO app were showcased: nostalgia, gardening, nature, and instrumental daily life activities, each offering a rich and immersive VR experience.
[0061] The SENSO app delivers an unprecedented sensory experience by integrating fully immersive VR technology. The app encompasses four core simulated scenarios: reminiscence, gardening, nature exploration, and everyday life activities. Within these scenarios, olfactory elements are precisely synchronized with the VR content, allowing users to enjoy a comprehensive multi-sensory experience while engaging in physical activities, cognitive training, and promoting mental well-being.
[0062] SENSO's technical features and advantages include:
[0063] 1) Olfactory Synchronization: SENSO innovatively integrates olfactory elements into the VR system, enabling synchronous interaction between smell and other senses such as sight and hearing, bringing users a more realistic and immersive experience.
[0064] 2) Multi-sensory stimulation: By comprehensively utilizing multiple sensory stimulation methods, the SENSO application not only enhances user engagement and immersion, but also helps promote users' physical and mental health and quality of life.
[0065] 3) Customized user interaction: SENSO application has designed a variety of user interaction methods to meet the needs of different game themes and tasks, ensuring that users can easily get started and enjoy the game process.
[0066] 4) Market Uniqueness: Currently, there is a lack of VR applications on the market that can provide olfactory synchronization. The launch of the SENSO application fills this gap and brings users a brand-new VR experience.
[0067] 5) Gamified Tasks: The gamified tasks in the SENSO app are well-designed, not only highly responsive and interactive, but also able to simulate real-life scenarios, helping users to better immerse themselves in the game world.
[0068] 6) Glove-based user input: To further enhance the user experience, the SENSO application also adopts a glove-based user input method, making user operations more intuitive and convenient.
