A system for eye-tracking according to an embodiment of the present invention includes a data collection unit that acquires face information of a user and location information of the user from an image captured by a photographing device installed at each of one or more points set within a three-dimensional space and an eye tracking unit that estimates a location of an area gazed at by the user in the three-dimensional space from the face information and the location information, and maps spatial coordinates corresponding to the location of the area to a three-dimensional map corresponding to the three-dimensional space.

System and method for eye-tracking

A user terminal according to an embodiment of the present invention includes a content providing unit for displaying a text-type advertisement content on a lock screen according to an input of a user, a gaze tracking unit for acquiring, through a photographing device, a face image of the user and a vector indicating a direction in which a face of the user faces, and tracking a gaze of the user from the face image and the vector, so as to determine whether the user has read the text-type advertisement content, and a reward providing unit for providing a set reward when it is determined that the user has read the text-type advertisement content. A text-reading based reward-type advertisement service may be provided with the user terminal.

Method for providing text-reading based reward-type advertisement service and user terminal for executing same

A terminal according to an embodiment is for tracking eyes on the basis of a first eye tracking model in which multiple pieces of learning data related to line-of-sight information are accumulated. The terminal may include a data collecting unit which obtains a facial image of a user using an imaging device, and extracts line-of-sight information about the user from the facial image, a data transmitting unit which transmits, to a server, the line-of-sight information about the user and location information about a point to which a line of sight of the user is directed within a screen of the terminal; a model receiving unit which receives from the server a second eye tracking model obtained by training the first eye tracking model with the line-of-sight information and the location information, and an eye tracking unit which tracks eyes of the user using the second eye tracking model.

Method for eye-tracking and terminal for executing the same

An input device includes a display unit for displaying, on a screen, at least one key having a display region and a recognition region, a gaze tracking unit for calculating a gaze position of a user on the screen, and an input unit for determining, when the gaze position exists inside a recognition region of a particular key from among the at least one key, that a corresponding character in a display region of the particular key has been inputted.
