Abstract

The present disclosure discloses a method, an apparatus and a system for determining line of sight, and a wearable eye movement device. The method includes: acquiring first gaze information of a user relative to a line of sight tracking module, where the line of sight tracking module closes to the user and moves with the user; acquiring a relative parameter between the line of sight tracking module and a fixed object; and determining second gaze information corresponding to the first gaze information according to the relative parameter. The present disclosure solves the technical problem that that the line of sight of the driver cannot be accurately determined in the prior art.
