A versatile dataset for text entry evaluations based on genuine mobile emails

Published: 30 August 2011 Publication History

Abstract

Mobile text entry methods are typically evaluated by having study participants copy phrases. However, currently there is no available phrase set that has been composed by mobile users. Instead researchers have resorted to using invented phrases that probably suffer from low external validity. Further, there is no available phrase set whose phrases have been verified to be memorable. In this paper we present a collection of mobile email sentences written by actual users on actual mobile devices. We obtained our sentences from emails written by Enron employees on their BlackBerry mobile devices. We provide empirical data on how easy the sentences were to remember and how quickly and accurately users could type these sentences on a full-sized keyboard. Using this empirical data, we construct a series of phrase sets we suggest for use in text entry evaluations.
