Intermodal improvement: Nudging users to use keyboard shortcuts

Abstract

Keyboard shortcuts have been proven to be the most efficient method of issuing commands in computer software. Using the mouse in graphical user interfaces provides an intuitive but slow method for executing functions in a software. Many fail to make the transition to faster modalities, such as keyboard shortcuts. This is not just the case for novices, but also users with years of experience. This study examines the research on this behavior, as well as how the concepts of nudging and ambient suggestion can be used to actively encourage and support the usage of keyboard shortcuts. Based on this research, a design is proposed and implemented in a simple word processor application. A user experience evaluation was done, by having participants perform writing and formatting tasks inside the application. Using the Microsoft Reaction Card Method followed by a semi-structured interview, the users elaborated on their experience. In the interviews topics and questions of motivation, distraction, and annoyance were raised. The results showed that most participants found the system convenient and helpful in learning shortcuts without being too obtrusive. There are promising first indications of it having potential in promoting the usage of keyboard shortcuts, however further research is required in order to make any generalizations.
