Touch data, and in particular text-entry data, has been predominantly collected in laboratory settings, under controlled conditions. While touch and text-entry data has consistently shown its potential for monitoring and detecting a variety of conditions and impairments, its deployment in-the-wild remains a challenge.
In the paper, WildKey, an Android keyboard toolkit is presented that allows for the usable deployment of in-the-wild user studies.
The toolkit is able to analyse text-entry behaviours through implicit and explicit text-entry data collection while ensuring user privacy. Additionally, each of the WildKey’s components and features, metrics collected are presented in detail, and the steps taken to ensure user privacy thus promoting compliance are discussed.
