• Hover or Tap? Supporting Pen-based Menu Navigation for Older Adults

  Karyn Moffatt, Sandra Yuen, Joanna McGrenere · 2008 · Proceedings of the 10th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '08)

  This paper investigates "drifting" — an error specific to pen-based (Tablet PC) interaction where users accidentally hover over an adjacent menu head, causing their intended menu to close and the wrong one to open. This occurs because inductive pen technology tracks the pen…
