Effects of Display Sizes on a Scrolling Task using a Cylindrical Smartwatch

With a growing interest in wrist-worn devices, research has typically focused on expanding the available interaction area for smartwatches. In this paper, we instead investigate how different display sizes influence task performance, while maintaining a consistent input area. We conducted an experiment in which users completed a scrolling task using a small display, a large display, and a cylindrical display wrapped around the wrist. We found that the large and cylindrical displays resulted in faster task performances than the small display. We also found that the cylindrical display removed constraints on the participants' body pose, suggesting that cylindrical displays have unique benefits for mobile interactions.
