Issues in number entry user interface styles: Recommendations for mitigation

Abstract

Interacting with numbers is a core part of using many interactive computer systems from the remote controls of electronic media appliances to user interfaces of high-integrity systems such as medical devices. Number entry systems are widely used on mobile devices. A wide variety of different user interface designs exist for interacting with numbers. The intricacies of the different styles are not well understood by designers and developers, especially for handling use error. This paper reviews these issues and provides recommendations for mitigating them.
