ROI Calculation Logic

In workplaces requiring eye-tracking input, correction tasks due to input errors significantly reduce productivity. Assuming this technology reduces error-induced correction time by ~70%, a worker performing 100 text inputs/day, 250 days/year, could save ~146 hours annually. At an hourly rate of ~$13.50 (AI est.), this translates to ~$2K/year per worker (AI est.). For a facility with 100 workers, this could yield ~$200K/year in direct savings (AI est.).
