1. Background

Eyegaze analysis is a research methodology which examines human's eye movement patterns using eye tracking technology. In eye tracking technology, video-based eye trackers are now most widely used. Most video-based eye trackers use infrared or near-infrared light and infrared camera to track pupil. Eye trackers make researchers know where people look at and eye scan path. Recently, eyegaze analysis and eye tracking technology are used in many areas. Like cognitive science, usability research and marketing, they are applicable for various research disciplines. Also it has a big interest that even commercial area; input device for disabled people, measuring effects of advertising media. Otherwise, eyegaze analysis is difficult to use individual researchers because of analysis methodologies. Eye tracking data needs to be statistically analyzed. This process makes researchers feel complicated and difficult to use. 2. Purpose 'Eyetrack ' is an eyegaze analysis software developed for using eye tracking data easily. It takes a role of visual processing and organizing eye movement data. After eyegaze experiment for any usage, designers or researchers can handle eye tracking data without statistical analyzing process. Also it provides many Eyetrack – Developing eyegaze analysis visualization software for designers ’ us
