Supporting Mobile Sensemaking Through Intentionally Uncertain Highlighting
summary
A mobile highlighting prototype uses force touch to sweep a center-out selection with fuzzy bounding boxes and a posthoc expandable context viewer. A two-part study (24 people for speed tasks, 19 for sensemaking) shows fuzzy selection cuts median selection time from about 6.0s to 1.7s, lowers NASA-TLX workload, and becomes the preferred method (none chose the baseline exact-handle selection). Implementation limits: max highlight size and occasional desire for one-directional expansion.
