ROI Calculation Logic

This technology significantly reduces manual effort for sign language CG production. For example, if a sign language CG content production process traditionally required 100 hours for word duration adjustment, this technology could reduce it to 20 hours. Assuming 1,000 hours of annual work, this represents an 80% reduction in effort. With labor costs estimated at ~$35/hour (AI est.), this could result in ~$25K/year (AI est.) in savings per project. Applying this across multiple projects and content could yield over ~$100K/year (AI est.) in cost reductions.

Speed to Market
6× faster than in-house development
This technology's strength lies in its established multivariate regression analysis model for sign language word duration and its usable database of sign language sequences and their durations. Therefore, rather than developing an equivalent system from scratch, integrating it as a software module into existing CG video generation systems or content production workflows is expected to enable extremely rapid deployment and operation. The proven algorithm promises early market entry and competitive advantage.

Technical Feasibility
This technology is software-based, centered on a database of sign language sequences paired with their durations and a multivariate regression analysis model. This makes it technically easy to integrate as a module into existing CG video generation software or content management systems. Comprising a word frequency vector generation unit and a multivariate regression analysis unit as described in the patent claims, it requires no specialized hardware, thus presenting low adoption barriers.
Success Scenario
Upon adopting this technology, the effort required for adjusting individual sign language word durations in CG video production could be reduced by up to 80%. This could shorten content production cycles, accelerate time-to-market, and is estimated to yield millions of dollars in annual production cost savings. Furthermore, more natural sign language expressions are expected to enhance viewer comprehension and engagement.
