ZWPS and Pressure Scroll: Two Pressure-based Techniques in Pen-based Interfaces

This paper investigates the interaction ability when introducing pressure into current basic interaction techniques by developing two novel techniques. A Zoom-based technique with pressure (hereafter referred to as ZWPS) is proposed to improve pixel-target selection. In this technique the pressure is used as a switch mode to couple a standard Point Cursor and a zoomable technique together. Pressure Scroll is also presented with a view to advancing scrolling performances by employing arc or line strokes to scroll documents. In this technique pressure is used as an additional control factor to widen the adjustable range of the scrolling velocity. We conducted two experiments to examine the effectiveness of ZWPS and Pressure Scroll. The experimental results indicate that they both bring significant benefits to the users.
