Lag compensation by image deflection and prediction: a review on the potential benefits to virtual training applications for manufacturing industry

An immersive virtual reality system can be used to simulate manufacturing facilities for training purposes. However, time lags can limit the realism of such a simulation. These lags occur when an immersive virtual reality system responds to head and hand movements. Time lags have been shown to degrade the performance of a hand manipulation virtual training task. Lag compensation is, therefore, desirable. This paper highlights the lag problem with virtual training applications and explores potential benefits of an existing lag compensation technique. This lag compensation technique used image deflection and prediction algorithms that were originally developed for virtual reality flight simulation applications
