We present a data logging concept, tool, and analyses to facilitatestudies of everyday mobile touch keyboard use andfree typing behaviour: 1) We propose a filtering concept to logtyping without recording readable text and assess reactions tofilters with a survey (N=349). 2) We release an Android keyboardapp and backend that implement this concept. 3) Basedon a three-week field study (N=30), we present the first analysesof keyboard use and typing biometrics on such free texttyping data in the wild, including speed, postures, apps, autocorrection, and word suggestions. We conclude that researchon mobile keyboards benefits from observing free typing beyondthe lab and discuss ideas for further studies.    «
