Smart Phone Keyboard Layout Usability

The purpose of this article was the evaluation of the performance and usability for an alternative keyboard layout on a smart phone compared to the dominant QWERTY layout on a smart phone when presented to users gradually versus immediately. Alternative keyboards have been rejected time and time again for typing with ten fingers. Various studies have attempted to explain reasons regarding this. This article found that users' perceived usability was not more favorable toward the gradually changing keyboard layout as compared to the keyboard layout being presented immediately.
