ROI Calculation Logic

Assuming early detection and intervention using this technology could reduce the transition to care-dependent status by 5%. With an average annual healthcare cost of ~$20K (AI est.) per care-dependent individual, this could result in ~$1M (AI est.) in annual healthcare cost savings for a target population of 10,000 elderly individuals ($20K × 10,000 × 5%). This has the potential to significantly contribute to social security cost reduction.

Speed to Market
4× faster than in-house development
This technology benefits from an established algorithm for frailty assessment based on specific gait cycle timings, facilitating easy integration with general-purpose wearable sensors. This allows licensees to significantly reduce R&D time, starting directly from the integration and validation phase with existing systems, potentially shortening time-to-market by approximately 2.5 years.

Integration Roadmap — Estimated 18-Month Deployment
Requirements Definition & System Design
Duration: 4 months
Define integration requirements with existing systems, select sensors, establish data protocols, and customize the assessment algorithm. Conduct initial validation through a Proof of Concept.
Prototype Development & Validation
Duration: 8 months
Develop a prototype of the frailty assessment support system based on the design. Conduct pilot studies with a small group of subjects to validate assessment accuracy, usability, and system stability, identifying areas for improvement.
On-site Deployment & Optimization
Duration: 6 months
Deploy the validated system into actual medical/care settings or health services for full-scale operation. Continuously optimize operational workflows and improve functionalities based on field feedback to maximize effectiveness.
Technical Feasibility
This technology leverages gait data from general-purpose wearable sensors, eliminating the need for significant investment in new dedicated hardware. The assessment unit described in the patent claims can be implemented in software, allowing for easy integration with existing health management or medical information systems via API. This enables adopting companies to achieve rapid system construction and operation with relatively low technical hurdles.
Success Scenario
Upon adopting this technology, companies could automatically assess individuals' frailty risk from daily gait data. This is estimated to improve the efficiency of frailty assessment tasks, which previously relied on in-person expert evaluation, by 20%, enabling preventive interventions for a larger elderly population. Consequently, it could contribute to extending healthy lifespans across communities and establishing new healthcare service models.
