A notable difference in the human-computer interface of a smartphone from that of a desktop computer are the techniques used to scroll a portion of the display. On a desktop, scroll is typically achieved by dragging the mouse on scrollbars displayed on the right and bottom sides of the scrolling region. On the other hand, scroll bars are often not used on a smartphone. (If used they appear as thin lines to indicate what portion of the underlying display is currently visible.) Scrolling is thus achieved by the gesture of a sliding touch across the display screen.

b. Based on cognetics, what arguments can be made in support of this difference?
