Improving Mobile User Experience of New Features Through Remote Tests and Evaluation

摘要

This paper presents a process to evaluate a new feature which allowed users to do gestures in a fingerprint sensor located at the bottom of smartphones. The idea was, with these gestures in the fingerprint sensor, users could perform all functions available on a typical Android navigation bar (go back, go to home screen and open the recent apps), so that the navigation bar could be hidden from all screens, allowing the users to enjoy a larger screen in all apps. The whole evaluation process was remotely performed at the end of the development process, with 115 participants receiving a smartphone containing not only the new feature to be evaluated but also a few embedded apps to collect logs, let users raise any issues they found and answer user satisfaction surveys after some time using the feature. The findings from this evaluation process were useful to refine the feature, enhance the user experience and make all stakeholders more confident about the user's acceptance before releasing it to market.
