METHOD AND SYSTEM FOR DETERMINING THE RELATIVE GAZE-ATTRACTING POWER OF VISUAL STIMULI

摘要

An system and method for enabling an individual to pretest stimulus alternatives, by carrying out eye-tracking experiments on a subject with a digital camera, a personal computer and webcam, or a camera built into a laptop, tablet, smart phone, or other mobile device. The method of implementing the invention may be based on use of the internet for transmitting experimental stimuli, data, and/or results. The method enables the practitioner to determine which of two or more competing stimulus images, displayed at the same time, draws more spontaneous gaze direction from the subject during the first few moments of exposure. The method enables one to express the result as a ratio or other comparative index.

主权项

1. A computer-implemented method of determining the response of an individual subject to a pair of visual stimuli, comprising the steps of:
a. Causing a first image and a second image to simultaneously appear on the screen of a display device; b. Causing a camera attached to or built in to the display device to record the direction of gaze of the subject over a pre-determined period of time; c. Causing said display device to transmit to a receiving computer the recorded direction of gaze, the identity of the images displayed at the time of the recording, and the location on the screen of each of the images; and d. Calculating how often the subject was coded as gazing towards the first image and how often the subject was coded as gazing towards the second image.
