FIG. 3.

Individual head velocity traces in red (A and B) and eye velocity traces in blue (C and D) for the first 6 consecutive head impulses using the search coil (A and C) and VOG (B and D). The x-axis corresponds to time in seconds; the axes for search coil and VOG are somewhat offset, given differences in the systems regarding when the first head impulse occurs relative to time 0, that is, the offset does not represent real-time latency differences. The EyeSeeCam records head movements in 3D (yaw, pitch, roll) and eye movements in 2D (yaw and pitch); these same axes were used for search coil recording also.
