In computer graphics, proposing efficient and usable human-computer interaction design solutions is a challenging task. Well defined guidelines and principles are very useful for designers to design new solutions for systems. To create these guidelines and principles, firstly differences among systems should be identified. In this study, we focused on comparing large screen systems and mobile-size/desktop-size screen systems by observing users while they interact with all three different size screens. We noticed that there are physical differences between these systems such as viewing distance, pixel count and weight. We also noticed that there are different applications for different usage areas. According to this, eight types of differences are defined and usability differences are categorized into these difference types. As a result, we conclude that large touchscreen systems need separate interaction design guidelines and principles.
