Abstract:

Summary The issue with HP laptops that have a touch pad with a scroll zone contained it (as shown in image A) is that they do not provide a tactile cue for the user to help interpret what section of the touch pad the finger is positioned at. In the absence of a tactile cue, it is difficult for the user to determine whether the finger is on touch pad or the scroll zone without looking at it, resulting in the accidental scrolling on the screen when actually the user simply wants to move the cursor. The issue and multiple solutions are discussed ahead.
