As shown in FIG. 8, the smartphone 1 includes an infrared irradiation unit 17. The infrared irradiation unit 17 emits infrared rays in synchronization with photographing performed by the camera 12.

  The storage 9 stores a line-of-sight detection program 9D. The line-of-sight detection program 9D provides a function for detecting the movement of the user's line-of-sight position. The line-of-sight position corresponds to a position on the touch screen display 2 when a line of sight extending linearly starting from the center position of the pupil in the user's eyeball intersects the touch screen display 2.

  The line-of-sight detection program 9D detects the line-of-sight position as follows. That is, the line-of-sight detection program 9D detects the line-of-sight position by applying an algorithm based on the corneal reflection method to the user's image. Specifically, the line-of-sight detection program 9D irradiates infrared rays from the infrared irradiation unit 13 when acquiring a user's image. The line-of-sight detection program 9D identifies the position of the pupil and the position of infrared corneal reflection from the acquired user image. The line-of-sight detection program 9D specifies the direction of the user's line of sight based on the positional relationship between the position of the pupil and the position of infrared corneal reflection. The line-of-sight detection program 9D determines that the direction of the line of sight is the eye corner side if the position of the pupil is closer to the corner of the eye than the position of the corneal reflection, and if the position of the pupil is closer to the eye than the position of the corneal reflection, It is determined that the direction of the line of sight is the eye side. The line-of-sight detection program 9D calculates the distance between the user's eyeball and the touch screen display 2 based on the size of the iris, for example. The line-of-sight detection program 9D is based on the direction of the user's line of sight and the distance between the user's eyeball and the touch screen display 2, and the line of sight starting from the pupil is located at the center position of the pupil in the user's eyeball. Detects the line-of-sight position, which is the position on the touch screen display 2 when crosses the touch screen display 2.

  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. The line-of-sight detection program 9D follows, 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. Detect as eye movement. When the line-of-sight movement detected by the line-of-sight detection program 9D is the same as the number of lines or columns of a plurality of character strings included in the specific mail, the control program 9A displays the character information. It is detected as the movement of the line of sight to follow. The character information displayed on the touch screen display 2 includes character information included in an e-mail, character information included in an SMS (Short Message Service), character information included in an MMS (Multimedia Messaging Service), and the like. .

  The control program 9A has a pattern in which the movement of the line of sight of the user is formed 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. 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. By determining whether to do so, movement of the line of sight following the character information may be detected.
