Abstract

The system determines the operator of the in-vehicle information terminal device without using a dedicated sensor. [Solution] The display unit 220 of the in-vehicle information terminal device is set to display information in two tile-shaped areas 300L and 300R side by side. Left tile flick input trajectory information related to the left tile flick input trajectory FMTL, which is the input trajectory of a flick operation detected in the area corresponding to the left tile 300L, and right tile flick input trajectory information related to the right tile flick input trajectory FMTR, which is the input trajectory of a flick operation detected in the area corresponding to the right tile 300R are sequentially stored in the memory unit. The stored left tile flick input trajectory information and right tile flick input trajectory information are compared to determine the degree of trajectory agreement and to determine whether there is one or more operators of the in-vehicle information terminal device.
