ROI Calculation Logic

Assuming a 20% reduction in average rehabilitation period. For a facility with 100 patients annually, each receiving ~$670 (AI est.) in rehabilitation, annual cost savings could be ~$15K (AI est.). Increased bed turnover due to shorter stays could generate ~$15K (AI est.) in additional revenue. A 10% improvement in specialist work efficiency could reduce personnel costs by ~$20K (AI est.). Total estimated economic impact: ~$50K/year (AI est.).

Speed to Market
6× faster than in-house development
This technology, developed by a national university corporation, has likely completed fundamental research and core technology validation. The patent describes modular components like a flexible, floor-separated display and fixation parts, which can be realized by combining existing projection, material, and sensor technologies. This suggests that proof-of-concept data and algorithms are likely well-established, enabling licensees to significantly shorten development time and accelerate market entry compared to in-house development.

Technical Feasibility
This technology is described in the patent claims as a modular configuration where a "first display unit is attached" to a walking assistance device. This suggests relatively easy retrofitting to existing walking assistance equipment or rehabilitation treadmills. Specifically, the combination of a flexible display and video projection can be achieved using general-purpose projectors, sensors, and elastic materials, implying implementation without extensive capital investment. This allows licensees to leverage existing infrastructure and rapidly deploy the technology with minimal technical hurdles.
Success Scenario
If this technology is adopted, medical facilities could see an increase in patient rehabilitation motivation, potentially shortening average rehabilitation periods by approximately 20%. This could promote more efficient use of medical resources and allow for the treatment of more patients. Furthermore, patients could apply this for self-training at home, significantly contributing to maintaining their quality of life post-discharge. As a result, adopting organizations are estimated to achieve both improved patient satisfaction and enhanced operational efficiency.
