improving stylus interaction for emedical forms
Using a stylus as the input device to fill forms- is frustrating because standard form controls are optimised for keyboard and mouse entry. We have augmented the behaviour of the three most common form controls to improve support for stylus input. Furthermore, because the target users are medical clinicians and they frequently annotate images, we have built an image annotation control. We report the design and implementation of stylus-friendly controls and two evaluations: the first to usability test all the new controls and the second to compare performance between the new selection controls and standard selection controls. All the new data controls were preferred by the study participants and the selection controls are faster and less error prone. The image annotation control was found to be easy to use and allows extra data to be collected.
