ROI Calculation Logic

Estimates cost savings from reducing junior doctor training duration. For a medical institution training 50 junior doctors annually, assuming an average training reduction of 2 months per doctor. With a monthly personnel cost (including training-related costs) of ~$5,350/person (AI est.), the annual cost reduction is calculated as 50 people × 2 months × ~$5,350/person = ~$535,000 (AI est.). Further medical cost reductions from fewer surgical errors are also expected, potentially increasing the total economic impact.

Speed to Market
6× faster than in-house development
Implementing this technology could significantly shorten development time compared to in-house efforts. The patent's abstract and claims indicate that the core algorithm for generating AR display information by integrating 3D positional data and captured images is already established. This eliminates the need for licensees to conduct R&D from scratch, allowing them to focus on integration into existing systems and application development. The reliability of the algorithm, supported by validation data, provides a strong basis for rapid transition from PoC to full-scale deployment.
