Hyper Typer: A Serious Game for Measuring Mobile Text Entry Performance in the Wild


In this paper we introduce Hyper Typer, a serious Android game for collecting text entry performance data on a large scale in an unsupervised manner. Publishing the game on the Google Play Store resulted in a total of 1,917 usable transcribed phrases with 58,829 keystrokes over an eleven-week period. By analyzing the data, we demonstrate the feasibility of the method and give preliminary results regarding the overall performance and error rate of players. Moreover, the collected data allows us to compare two of the most commonly used Android soft-keyboards.
