This design will wrap the existing lighthouse driver while providing additional functionality to expose IMU data through a custom interface.\n\n## 1. Overall Architecture\n\n```mermaid\ngraph TD\n    A[SteamVR Runtime] --> B[Our Custom Driver]\n    B --> C[Lighthouse Driver]\n    B --> D[Custom IMU Interface]\n    C --> E[Tracking & Pose Data]\n    D --> F[Raw IMU Data]\n    A --> G[Applications]\n    G --> H[Standard OpenVR API]\n    G --> I[Custom IMU API]\n    I --> D\n```\n\nOur solution will consist of the following components:\n\n1. **Custom Driver Wrapper** - The main driver that will be loaded by SteamVR\n2. **Lighthouse Driver Interface** - Component that communicates with the existing lighthouse driver\n3. **IMU Data Provider** - Component that accesses and exposes raw IMU data\n4. **Custom API Interface** - Interface for applications to access the IMU data\n\n## 2. Key Components and Interfaces\n\n### 2.1 Custom Driver Wrapper\n\nThis is the main entry point for our driver. It will implement:\n\n- `IServerTrackedDeviceProvider` - The main interface required by OpenVR for driver implementation\n- `HmdDriverFactory` - The factory function that returns our driver implementation\n\n```cpp\nclass IMUEnabledDeviceProvider : public vr::IServerTrackedDeviceProvider {\npublic:\n    vr::EVRInitError Init(vr::IVRDriverContext *pDriverContext) override;\n    void Cleanup() override;\n    const char *const *GetInterfaceVersions() override;\n    void RunFrame() override;\n    bool ShouldBlockStandbyMode() override;\n    void EnterStandby() override;\n    void LeaveStandby() override;\n\nprivate:\n    std::unique_ptr<LighthouseDriverWrapper> m_lighthouseDriver;\n    std::unique_ptr<IMUDataProvider> m_imuDataProvider;\n};\n```\n\n### 2.2 Lighthouse Driver Wrapper\n\nThis component will load and communicate with the existing lighthouse driver:\n\n```cpp\nclass LighthouseDriverWrapper {\npublic:\n    LighthouseDriverWrapper();\n    ~LighthouseDriverWrapper();\n    \n    bool Initialize();\n    void Shutdown();\n    \n    // Forward calls to the lighthouse driver\n    void RunFrame();\n    void EnterStandby();\n    void LeaveStandby();\n    \nprivate:\n    void *m_lighthouseDriverLib;\n    vr::IServerTrackedDeviceProvider *m_lighthouseProvider;\n};\n```\n\n### 2.3 IMU Data Provider\n\nThis component will access and expose the raw IMU data:\n\n```cpp\nclass IMUDataProvider {\npublic:\n    IMUDataProvider();\n    ~IMUDataProvider();\n    \n    bool Initialize();\n    void Shutdown();\n    \n    // Get the latest IMU sample for a specific device\n    bool GetLatestIMUSample(uint32_t unDeviceIndex, vr::ImuSample_t *pSample);\n    \n    // Register a device for IMU data access\n    void RegisterDevice(uint32_t unDeviceIndex);\n    \n    // Check if IMU data is available for a device\n    bool IsIMUDataAvailable(uint32_t unDeviceIndex);\n    \nprivate:\n    std::map<uint32_t, std::queue<vr::ImuSample_t>> m_imuSamples;\n    std::mutex m_imuSamplesMutex;\n};\n```\n\n### 2.4 Custom Device Driver\n\nWe'll need to create a custom device driver that wraps the existing device drivers and adds our IMU functionality:\n\n```cpp\nclass IMUEnabledDeviceDriver : public vr::ITrackedDeviceServerDriver {\npublic:\n    IMUEnabledDeviceDriver(vr::ITrackedDeviceServerDriver *pWrappedDriver, IMUDataProvider *pIMUDataProvider);\n    ~IMUEnabledDeviceDriver();\n    \n    // ITrackedDeviceServerDriver interface\n    vr::EVRInitError Activate(uint32_t unObjectId) override;\n    void Deactivate() override;\n    void EnterStandby() override;\n    void *GetComponent(const char *pchComponentNameAndVersion) override;\n    void DebugRequest(const char *pchRequest, char *pchResponseBuffer, uint32_t unResponseBufferSize) override;\n    vr::DriverPose_t GetPose() override;\n    \nprivate:\n    vr::ITrackedDeviceServerDriver *m_pWrappedDriver;\n    IMUDataProvider *m_pIMUDataProvider;\n    uint32_t m_unDeviceId;\n};\n```\n\n### 2.5 Custom IMU Component Interface\n\nWe'll create a custom component interface that applications can use to access the IMU data:\n\n```cpp\nclass IVRIMUComponent {\npublic:\n    // Get the latest IMU sample\n    virtual bool GetLatestIMUSample(vr::ImuSample_t *pSample) = 0;\n    \n    // Check if IMU data is available\n    virtual bool IsIMUDataAvailable() = 0;\n    \n    // Get IMU data even when optical tracking is lost\n    virtual bool GetIMUDataInFallbackMode(vr::ImuSample_t *pSample) = 0;\n};\n\nstatic const char *IVRIMUComponent_Version = \"IVRIMUComponent_001\";\n```\n\n## 3. Implementation Details\n\n### 3.1 Driver Loading and Initialization\n\n1. SteamVR loads our custom driver\n2. Our driver loads the lighthouse driver\n3. We initialize our IMU data provider\n4. We register our custom device drivers with SteamVR\n\n```cpp\nvr::EVRInitError IMUEnabledDeviceProvider::Init(vr::IVRDriverContext *pDriverContext) {\n    VR_INIT_SERVER_DRIVER_CONTEXT(pDriverContext);\n    \n    // Initialize the lighthouse driver wrapper\n    m_lighthouseDriver = std::make_unique<LighthouseDriverWrapper>();\n    if (!m_lighthouseDriver->Initialize()) {\n        return vr::VRInitError_Driver_Failed;\n    }\n    \n    // Initialize the IMU data provider\n    m_imuDataProvider = std::make_unique<IMUDataProvider>();\n    if (!m_imuDataProvider->Initialize()) {\n        return vr::VRInitError_Driver_Failed;\n    }\n    \n    return vr::VRInitError_None;\n}\n```\n\n### 3.2 Accessing IMU Data\n\nThe key to our solution is accessing the raw IMU data from the devices. We'll do this by:\n\n1. Using the `ImuSample_t` struct defined in openvr_driver.h\n2. Monitoring the device's tracking state to detect when optical tracking is lost\n3. Providing the IMU data through our custom component interface\n\n```cpp\nbool IMUDataProvider::GetLatestIMUSample(uint32_t unDeviceIndex, vr::ImuSample_t *pSample) {\n    std::lock_guard<std::mutex> lock(m_imuSamplesMutex);\n    \n    auto it = m_imuSamples.find(unDeviceIndex);\n    if (it == m_imuSamples.end() || it->second.empty()) {\n        return false;\n    }\n    \n    *pSample = it->second.front();\n    it->second.pop();\n    \n    return true;\n}\n```\n\n### 3.3 Handling Optical Tracking Loss\n\nWhen optical tracking is lost, we'll detect this through the tracking result in the device pose:\n\n```cpp\nvoid *IMUEnabledDeviceDriver::GetComponent(const char *pchComponentNameAndVersion) {\n    // First check if the wrapped driver provides this component\n    void *pComponent = m_pWrappedDriver->GetComponent(pchComponentNameAndVersion);\n    if (pComponent) {\n        return pComponent;\n    }\n    \n    // If the component is our custom IMU component, return it\n    if (strcmp(pchComponentNameAndVersion, IVRIMUComponent_Version) == 0) {\n        return static_cast<IVRIMUComponent*>(this);\n    }\n    \n    return nullptr;\n}\n\nbool IMUEnabledDeviceDriver::GetIMUDataInFallbackMode(vr::ImuSample_t *pSample) {\n    vr::DriverPose_t pose = GetPose();\n    \n    // Check if optical tracking is lost\n    if (pose.result == vr::TrackingResult_Fallback_RotationOnly ||\n        pose.result == vr::TrackingResult_Calibrating_OutOfRange ||\n        pose.result == vr::TrackingResult_Running_OutOfRange) {\n        \n        // Get the IMU data from the provider\n        return m_pIMUDataProvider->GetLatestIMUSample(m_unDeviceId, pSample);\n    }\n    \n    return false;\n}\n```\n\n### 3.4 Exposing IMU Data to Applications\n\nApplications will access the IMU data through our custom component interface:\n\n```cpp\n// In the application\nvr::IVRIMUComponent *pIMUComponent = (vr::IVRIMUComponent*)\n    vr::VRSystem()->GetTrackedDeviceInterface(\n        vr::k_unTrackedDeviceIndex_Hmd, \n        IVRIMUComponent_Version);\n\nif (pIMUComponent) {\n    vr::ImuSample_t imuSample;\n    if (pIMUComponent->GetLatestIMUSample(&imuSample)) {\n        // Use the IMU data\n        // imuSample.vAccel - Accelerometer data\n        // imuSample.vGyro - Gyroscope data\n        // imuSample.fSampleTime - Timestamp\n    }\n}\n```\n\n## 4. Driver Configuration\n\n### 4.1 Driver Manifest\n\n```json\n{\n  \"alwaysActivate\": true,\n  \"name\": \"imu_enabled_driver\",\n  \"directory\": \"\",\n  \"resourceOnly\": false,\n  \"hmd_presence\": [\"*.*\"]\n}\n```\n\n### 4.2 Settings\n\nWe'll provide configuration options in the driver's settings:\n\n```json\n{\n  \"driver_imu_enabled\": {\n    \"enable\": true,\n    \"loadPriority\": 100,\n    \"enableImuFallback\": true,\n    \"imuSampleRate\": 1000,\n    \"imuBufferSize\": 100\n  }\n}\n```\n\n## 5. Implementation Challenges and Solutions\n\n### 5.1 Challenge: Accessing the Lighthouse Driver's IMU Data\n\nThe lighthouse driver doesn't directly expose IMU data through a public interface.\n\n**Solution**: We'll use the `k_pch_Lighthouse_EnableImuFallback_Bool` setting to enable IMU fallback in the lighthouse driver, and then intercept the IMU data through our wrapper.\n\n### 5.2 Challenge: Synchronizing with the Lighthouse Driver\n\nWe need to ensure our driver doesn't interfere with the lighthouse driver's normal operation.\n\n**Solution**: We'll use a proxy pattern to forward all calls to the lighthouse driver while adding our IMU functionality.\n\n### 5.3 Challenge: Performance Impact\n\nAccessing raw IMU data could impact performance.\n\n**Solution**: We'll implement efficient buffering and only process IMU data when needed.\n\n## 6. Testing and Validation\n\n1. **Unit Testing**: Test each component in isolation\n2. **Integration Testing**: Test the complete driver with SteamVR\n3. **Performance Testing**: Measure the performance impact of our driver\n4. **Validation Testing**: Verify that IMU data is available when optical tracking is lost\n\n## 7. Implementation Roadmap\n\n1. **Phase 1**: Create the basic driver structure and wrapper for the lighthouse driver\n2. **Phase 2**: Implement the IMU data provider and custom component interface\n3. **Phase 3**: Test and validate the solution\n4. **Phase 4**: Optimize performance and reliability\n5. **Phase 5**: Document the API and provide sample code for applications\n\nPlease implement these files according to the design specifications. The implementation should be compatible with the existing OpenVR codebase and follow the same coding style and conventions. Remember to update all class names to use \"Sauna\" instead of \"IMUEnabled\" as specified in the implementation steps.\n\nThese specific instructions supersede any conflicting general instructions you might have.
