Augmented Reality Visualization of BPPV Otoconia Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tools lack the capability to effectively visualize the movement of displaced otoconia inside the inner ear and their relationship with nystagmus, making it difficult for inexperienced practitioners to accurately diagnose and treat benign paroxysmal positional vertigo (BPPV).
Innovation Solution
A system and method for augmented reality visualization of BPPV, which includes a camera to capture image sequences, a processing unit to generate accurate anatomical virtual models of the inner ear, and a display to overlay these models in real-time over the image sequences, allowing for visualization of virtual displaced otoconia and their movement in response to head movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional diagnostic tools are used, then the diagnosis process is simple, but the visualization capability of otoconia movement and nystagmus relationship is insufficient
Solution Approach 1:
The patent creates virtual copies of the inner ear anatomy and otoconia movement patterns through augmented reality overlays. These virtual models replicate the physical structures and their dynamic behavior, allowing practitioners to visualize otoconia movement and nystagmus relationships without complex surgical tools or invasive procedures.
Solution Approach 2:
The augmented reality display acts as an intermediary between the practitioner and the patient's inner ear conditions. It translates invisible physiological processes (otoconia movement, nystagmus) into visible visual representations, bridging the gap between diagnostic capability and visualization without requiring direct observation of the inner ear.
2Measurement precision
If augmented reality visualization is implemented, then the visualization of otoconia movement is enhanced, but the device complexity increases
Solution Approach 1:
The augmented reality system serves multiple functions: it visualizes otoconia movement, displays nystagmus patterns, provides anatomical orientation, and guides diagnostic procedures. By consolidating these functions into a single integrated display system, the patent reduces overall system complexity while maintaining high visualization accuracy.
Solution Approach 2:
The system uses color coding and visual variations to represent different anatomical structures, movement directions, and physiological states. This allows for accurate differentiation and visualization of complex inner ear dynamics through intuitive visual cues, enhancing measurement precision without requiring complex display hardware.
3Reliability
If real-time visualization is provided, then the diagnostic accuracy is improved, but the processing requirements increase
Solution Approach 1:
The system pre-processes and stores anatomical models, movement patterns, and visualization parameters before the diagnostic procedure. This allows the real-time display to focus only on overlaying pre-computed information rather than performing complex calculations during the procedure, reducing instantaneous processing power requirements while maintaining diagnostic accuracy.
