Accuracy improvement following drifting correction methods. a Tracking accuracy significantly improves upon STC (left), RTC (middle), and RSTC (right) correction methods. b Effect of increasing the number of correction frames on tracking accuracy with STC correction. c Comparison of tracking accuracy between RTC, and RSTC corrections. Error bars refer to SEM across the 20 subjects (*** \(p<0.001\))
