Absolute Indirect Touch Interaction: Impact of Haptic Marks and Animated Visual Feedback on Usability and User Experience
Résumé
Goal of this paper is to investigate usability and user experience (UX) of a touch-based control of user interfaces that the user can not directly interact with. An example is a user controlling the television screen via a touch interaction on the remote control, or the driver of a car using touch to control the input on the steering wheel for the middle-console screen.
Based on a controlled within subject experiment investigating touch based interaction with and without a haptic mark we replicate findings on usability that it is significantly faster to complete a task with haptic marks on the touch area than without haptic marks. For user experience the dimensions of pragmatic quality and attractiveness were rated higher for touch input with a haptic landmark. The variation of user interface animations for target selection did not have a significant impact on user experience, showing that the tactile feedback is the most prominent factor to determine user experience.The contribution concludes with a discussion how replication of studies must become part of user-centered design and development processes to handle the threat of outdated research due to technology change.
