Using heat maps for studying user preferences in vertical and horizontal multi-touch surfaces

This paper presents a study of muti-touch interactive surfaces based on the use of heat maps. The results of the study sheds light on two main issues that have not been researched formally thus far: User preferences between horizontal and vertical interactive surfaces, and preferred touch zones on both types of interactive surfaces. Our findings have implications for the design of user interfaces for multi-touch surfaces as well as for the use of vertical or horizontal surfaces in individual or collaborative settings.
