Abstract
A computing device (e.g., a host computer in communication with a tablet input device) receives pen data corresponding to first and second positions of a pen device. The computing device compares the first and second positions to obtain an angle and an offset distance between the positions. The computing device selects a scrolling direction (either vertical or horizontal) based on the angle, with the selection being biased towards vertical scrolling. The computing device determines a number of scrolling events based on the offset distance, which may include comparing the offset distance with a preselected minimum distance. The computing device sends the scrolling events to an application executing on the computing device. The scrolling events cause the application to render scrolling in the selected scrolling direction. The pen data may include an indication of pen-down status and/or pen button activation to help determine whether to activate or terminate scrolling.
