ROI Calculation Logic

Assuming a 20% increase in customer spending per VR attraction compared to conventional experiential content. With 500,000 annual users and an average price of $16.50 (AI est.) per user, the estimated additional revenue is 500,000 users × $16.50 (AI est.) × 20% = ~$1.5M/year (AI est.). Further efficiency gains in rehabilitation could also reduce healthcare costs.

Speed to Market
6× faster than in-house development
The patent abstract explicitly mentions "controlling the elevating mechanism 30," indicating that the basic operating principle is already established. Furthermore, the description notes that "the foot-mounted force feedback unit can be miniaturized," providing a clear design philosophy for implementation. This eliminates the need for licensees to develop from scratch, facilitating easy integration into existing VR systems and simulators, significantly shortening development time and enabling rapid market entry.
