Abstract

Large display and touch screens are becoming ubiquitous within the work place including multiple display screens. There is limited evidence on what configurations and arrangements of the display screens are most effective for data analysis. We conducted two user studies to understand the effectiveness of the display angle, physical size, resolution, and touch precision for data analysis activities. Our results indicated that touch interaction for data analysis sitting at a workstation was most effective with medium sized screens at 27, high precision touch accuracy (not 4K resolution), and display angle titled at 30°. The results from our studies can guide other researchers and developers who want to integrate large touch display screens into their work place environments.
