as shown in fig. 1 to 4, the present invention provides a device for calibrating a gaze point of a desktop eye tracker, comprising: the glasses comprise glasses 101, a clamping mechanism, a mounting plate 104, a photosensitive sensor 105, a lamp bead 106 and a controller, wherein an infrared emitter 103 is arranged at the bridge 102 of the glasses 101, and the infrared emitter 103 is used for emitting clustered infrared rays; the clamping mechanism is clamped on a display 107 of the table type eye tracker; mounting plate 104 is fixedly connected to the clamping mechanism; the photosensitive sensor 105 is arranged on the surface of the mounting board 104 and used for receiving the infrared rays emitted by the infrared emitter 103; the lamp beads 106 are arranged on the surface of the mounting plate 104; the controller is electrically connected with the photosensitive sensor 105 and the lamp beads 106, when the photosensitive sensor 105 detects infrared rays, the controller controls the lamp beads 106 to be electrified, and the controller is electrically connected with a power supply device.
The working principle of example 1 is now briefly described:
before the gazing point calibration is performed, the tester wears the eyeglasses 101, and the infrared emitter 103 on the eyeglasses 101 emits the bundled infrared rays. The tester adjusts the head posture so that the bundled infrared rays are irradiated on the photosensor 105. The photosensitive sensor 105 senses infrared rays and transmits optical signals to the controller, the controller controls the lamp beads 106 to be powered on, the lamp beads 106 are lightened, a tester stops the head from rotating immediately, at the moment, the desk type eye tracker is turned on, the desk type eye tracker display 107 displays a cross line, and a red dot on the cross line moves up and down or left and right along the cross line. The fixation point of the eyes of the tester is always concentrated on the red point, and the fixation point is calibrated by using a self-contained calibration program of the desk type eye tracker. In the process of calibrating the fixation point, if the head of a tester rotates, the photosensitive sensor 105 cannot sense infrared rays, the controller controls the lamp beads 106 to be powered off, the tester knows that the head of the tester rotates, and then the fixation point is calibrated again.
The device for calibrating the fixation point of the desk-top eye tracker can help a tester to adjust the head posture of the tester so as to ensure that the head keeps the optimal posture during testing, and can prompt the tester whether the head rotates or not during the fixation point calibration process, so that the tester can be prevented from generating errors in fixation point calibration due to head rotation.

Before the fixation point calibration is performed, a tester wears the glasses 101, adjusts the head posture by using the infrared emitter 103 and the photosensitive sensor 105, opens the laser range finder 202 on the frame 201 of the glasses 101, adjusts the distance between the head and the desk-top eye tracker in real time, and further adjusts the real-time distance between the laser range finder 202 and the reflector 203. The laser range finder 202 detects the distance between the laser range finder 202 and the reflector 203 in real time and transmits a distance value signal to the controller, a test distance range value is preset in the controller, the controller compares the real-time distance value with the preset test distance range value, and when the photosensitive sensor 105 detects infrared rays and the real-time distance value is within the preset test distance range value, the controller controls the lamp bead 106 to be electrified. Thereby allowing the tester to adjust the head to the optimal position from the desktop eye tracker. In the process of calibrating the fixation point, if the head of the tester moves, the laser range finder 202 detects that the real-time distance value is out of the preset test distance range value, the controller controls the lamp bead 106 to be powered off, the tester knows that the head of the tester moves, and then the fixation point is calibrated again. Through setting up laser range finder 202 and speculum 203, not only make the tester adjust the head apart from desk-top eye tracker optimum position, can also remind the tester head whether to take place to remove to prevent that the tester from leading to the calibration of point of fixation to appear the error because the head removes in carrying out the calibration of point of fixation.
Example 3:
on the basis of embodiment 2, in order to increase the sound reminding function, the reminding effect is improved.
As shown in fig. 3 and 4, the mounting board 104 is further provided with a speaker 3, the speaker 3 is electrically connected to the controller, and when the light-sensitive sensor 105 does not detect that the real-time distance value detected by the infrared ray or the laser range finder 202 is outside the preset test distance range value, the controller controls the speaker 3 to sound.
Through setting up speaker 3, when photosensitive sensor 105 does not detect infrared ray or the real-time distance value that laser range finder 202 detected outside predetermineeing test distance range value, then 3 vocalizations of controller control speaker to make the tester not only can obtain the visual warning, can also obtain sound and remind, thereby promote and remind the effect.
Example 4:
on the basis of embodiment 1, in order to prevent the clamping mechanism from shaking the photosensor 105 and the mirror 203 provided on the mounting board 104 due to poor clamping effect, thereby causing an error in the calibration of the gazing point.
