Over the past year on the MTAGIC project, we’ve been investigating differences in how children and adults make gestures and touch targets on mobile touchscreen devices. We have designed our study tasks to reflect the designs of existing apps on the market today, and have recently examined our data to understand the impact of visual feedback on gesture interaction for kids. Our paper on this topic, “Examining the Need for Visual Feedback during Gesture Interaction on Mobile Touchscreen Devices for Kids,” has been accepted to the Interaction Design and Children (IDC) conference! Read the abstract:
Surface gesture interaction styles used on modern mobile touchscreen devices are often dependent on the platform and application. Some applications show a visual trace of gesture input as it is made by the user, whereas others do not. Little work has been done examining the usability of visual feedback for surface gestures, especially for children. In this paper, we present results from an empirical study conducted with children, teens, and adults to explore characteristics of gesture interaction with and without visual feedback. We find that the gestures generated with and without visual feedback by users of different ages diverge significantly in ways that make them difficult to interpret. In addition, users prefer to see visual feedback. Based on these findings, we present several design recommendations for new surface gesture interfaces for children, teens, and adults on mobile touchscreen devices. In general, we recommend providing visual feedback, especially for children, wherever possible.
