In this study, a general-purpose saccade measurement method was investigated using multiple webcams to obtain high-speed pseudo-facial images. An eye-tracking system was constructed using a high-speed shooting method, in which the exposure timing changed when the cameras were reconnected, and the camera reconnection was adjusted such that the difference in the exposure timing was equal to the target shooting speed. In the experiment performed to verify the high-speed shooting method, although an increase in the variation over time was observed, the shooting speed was quasi-high when multiple cameras were used. In the saccade measurement experiment, the error rate of the saccade peak velocity was observed to be approximately 28 % when the stimulus movement was 10° or more, which was significantly lower than the error rate when a single camera was used. These results suggest that saccadic motion with a large shift of viewpoint, such as when viewing advertisements, can be captured using an inexpensive device for general use.
