Solution Overview

Problem

Conventional augmented reality healthcare systems rely on slow and expensive artificial intelligence algorithms for detecting patients and calculating their position and rotation in three dimensions, which are complex to develop and execute.

Innovation Solution

The system uses a mesh object of a patient's portion rotated in reference to two points, defined by x, y, and z coordinates, which is faster and less complex to engineer, involving a 3D source mesh object generation, orientation bar placement, and rotation calculations within a mixed reality smartglass framework.

Engineering Contradictions & Design Principles

1Measurement precision

If artificial intelligence algorithms are used to detect patients and calculate position and rotation, then measurement precision is improved, but device complexity and execution time increase

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the complex AI-based detection system into simpler geometric operations. Instead of using a monolithic AI algorithm, the system divides the problem into: (1) detecting key anatomical landmarks, (2) constructing a spatial mesh from these landmarks, and (3) performing separate rotation calculations around specific axes. This segmentation reduces overall system complexity while maintaining measurement precision.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a spatial mesh as an intermediary representation between raw sensor data and final position/rotation calculations. The mesh object serves as a mediator that simplifies the transformation process, allowing for more efficient computation of anatomical orientations without requiring complex AI algorithms for each calculation step.

Inventive Principle:

Solution Approach 1:

The patent performs preliminary construction of the spatial mesh and identification of key anatomical landmarks before the actual position and rotation calculations are needed. By pre-processing the data to establish the mesh structure and critical reference points, the system eliminates the need for complex real-time AI computations during measurement, thereby improving execution speed while maintaining precision.
