Resumo
Eye tracking is a technology that consists of calculating the eye gaze point of a user as he/she looks around. A device equipped with an eye tracker (ET) enables users to use their eye gaze as an input modality that can be combined with other input devices like mouse, keyboard, touch and gesture, referred as active applications in games, operative system navigation, e-books, market research studies, and usability testing. These eye tracker applications can be used for new assistive technologies. This work presents the development of a toolbox for Matlab with four modules which allow the use of eye-tracking systems for therapy (physical, psychological, medical), control of intelligent environment and studies about visual social attention. The results show that the interface allows the volunteers connecting from Matlab applications to the eye tracker device, control the sampling time, set-up and configure the system, managing the eye tracker data, generating analysis and graphic reports, and control the graphic interface.
