  In the above example, the case has been described in which the line-of-sight detection program 9D detects the user's line-of-sight position by executing processing using the cornea reflection method, but the present invention is not limited to this example. For example, the line-of-sight detection program 9D may detect the line-of-sight position by executing an image recognition process on the user's image. For example, the line-of-sight detection program 9D extracts a predetermined region including the user's eyeball from the user's image, specifies the line-of-sight direction based on the positional relationship between the eye and the iris, uses the specified line-of-sight direction, The line-of-sight position is detected based on the distance from the person's eyeball to the touch screen display 2. Alternatively, the line-of-sight detection program 9D accumulates, as reference images, images of a plurality of eyeballs when the user is browsing various display areas on the touch screen display 2, and acquires them as reference images and determination targets. The eye-gaze position is detected by collating with the image of the user's eyeball.

  The control program 9A is a function for detecting the movement of the line of sight following the character information included in the specific mail based on the movement of the line of sight detected by the line-of-sight detection program 9D after displaying the specific mail on the touch screen display 2. I will provide a.

By determining whether or not they match, the movement of the line of sight following the character information may be detected.

  The controller 10 executes the following process by executing the control program 9A and the line-of-sight detection program 9D. That is, after displaying the specific mail on the touch screen display 2, the controller 10 detects the movement of the line of sight following the character information included in the specific mail based on the movement of the line of sight detected by the line-of-sight detection program 9D. For example, when the movement of the line of sight detected by the line-of-sight detection program 9D corresponds to the arrangement direction of a plurality of character strings constituting the character information included in the specific mail, the controller 10 moves the line-of-sight following the character information. Detect as movement. When the line-of-sight movement detected by the line-of-sight detection program 9D is the same as the number of rows or columns of a plurality of character strings included in the character information included in the specific mail, the controller 10 follows the character information. Detect as eye movement. The controller 10 matches the pattern formed by the movement of the line of sight of the user when the line-of-sight locus formed by connecting the line-of-sight positions detected by the line-of-sight detection program 9D follows the character information included in the specific mail.
