We address the issue of enabling text entry for walk-up-and-use interactive
tabletop displays located in public spaces. Public tabletop installations are characterized by a diverse target user group, multiperson interaction, and the need for high approachability and intuitiveness. We first define the design constraints of text-entry methods for public tabletop installations such as clear affordances, audience expertise, support of direct-touch interaction, visual appearance, space requirements, multi-user support, and technical simplicity. We then describe an iterative design process that was informed by these constraints and led to the development of two stylus keyboard prototypes—BubbleQWERTY and BubbleCIRCLE - for use in interactive public tabletop installations.
