Design Considerations for a Large Display Touch Application in Informal Education
Large touch screens are an increasingly common platform for education. Effective design for this form factor will directly influence the effectiveness of these screens as educational tools. The sheer size of a large touch display can bring up issues related to distal access of touch targets and limited field of vision. The visibility of the screen at a distance and the ability for large groups to gather in front of such a display also mean that designers must create applications that are effective teaching tools for proximal visitors who only see part of the screen as well as attractive for distal visitors who see the screen from afar. We discuss our approach to these design challenges through the iterative design and qualitative evaluation of a touch screen exhibit about the life of Alfred Nobel hosted on an 82-inch touch screen. From this early investigation into the efficacy of large displays as informal educational tools, we present practical guidelines for designers working with this form factor.
