This study explores the design considerations and usability factors of using large multi touch interfaces. In this study, an experimental approach incorporating a large multi touch interface environment was used. End user usability test sessions supported with glasses type eye tracker and interview sessions were conducted. The data were collected from one expert and three non-expert users by implementing a task on a military training application. Two analysis methods were used, analysis for eye movement data of users and analysis for interviews. This study revealed that users were generally focusing at the center of the screen while using the large multi touch display. The most common gestures were Tap and Drag which are single touch input gestures. It was easy to adapt to the system by recalling the previous experiences from mobile devices, to manage the area on the screen, and to interact with two hands thanks to display size.
