SMI Eye-tracking device for control map application by sight

Tracking person´s eye movements have been used in many fields since the last decade. The eye tracking system is a device for measuring eye positions and eye movement ("where we are looking"). There are many approaches for research on user perception and evaluation of the usability and effectiveness of cartographic and geoinformatics products as well. Eye-tracking system offers great opportunity for objective analysis and evaluation, but there are not many ideas of non-contact control of map application by sight. The mouse and keyboard are inherent parts of computer for locomotive control nowadays and there is the same potential for control by sight for the future. But on the other side it requires the physical processes. Control by sight eliminates all constrains associated with locomotive control. It can be used by disabled users, in specialized field like army or aviation, as well as wide range of home users. This paper is based on eye-tracking research made on first eye-tracking device in the Czech Republic used on the field of cartography and geoinformatics. It generally describes eye-tracking technology for non-contact control, and then is followed by approach of map application control by sight. It is developed on SensoMotorics Instrument (SMI) device and SMI Experiment Suite 360° software. There have been elected rectangle areas located near the edge of map, with some time delay function. When user localizes one of these areas the map automatically moves to the way on which edge is localized on, short time delay prevents an accidental movement. The technology for recording the eye movements on the screen offers this option because if you properly define the layout and function controls, you need only connect these two components. The solution of movement control is based on data transmission between eye-tracking-device-output and converter in real-time.
