Using Electromyography to Predict Head Motion for Virtual Reality (2001)
"The objective of this research is to use neck and shoulder electroymograms (EMG) to predict head movements in immersive virtual environments in order to minimize time lags in updating the visual scene that can cause disorientation and simulation sickness. Visual update delays are a critical technical obstacle for implementation of head-mounted displays in a wide variety of applications from training simulations and mission rehearsal to teleoperation and telemedicine. These applications require a perceptually veridical mapping between actual head position and virtual spatial position in the synthetic environment. Figure 1 shows an example of a subject attempting to superimpose virtual and real objects where the virtual visual environment appears to
