These Aren't the Commands You're Looking For: Addressing False Feedforward in Feature-Rich Software

Abstract

The names, icons, and tooltips of commands in feature-rich software are an important source of guidance when locating and selecting amongst commands. Unfortunately, these cues can mislead users into believing that a command is appropriate for a given task, when another command would be more appropriate, resulting in wasted time and frustration. In this paper, we present command disambiguation techniques that inform the user of alternative commands before, during, and after an incorrect command has been executed. To inform the design of these techniques, we define categories of false-feedforward errors caused by misleading interface cues, and identify causes for each. Our techniques are the first designed explicitly to solve this problem in feature-rich software. A user study showed enthusiasm for the techniques, and revealed their potential to play a key role in learning of feature-rich software.
