Research Of Large Documentation Navigating Techniques With Pen Input Channels

Browsing documentation is a daily used computer task. Browsing techniques provide an accessing method of infinite information with limited screen space. Scrolling and zooming are basic methods for browsing large documentation. Large documentations are those that cannot be displayed in one screen. Obviously, most documentation can be called large documentations.Current pen input mainly utilizes the position of the pen tip, which provides x-y position, and occasionally a button press. Other input channels such as pressure, rolling angle, tilt and azimuth are rarely used, therefore, we explore pen input channels of pressure, rolling angle, tilt and azimuth for browsing large documentation in pen-based UIs.According to studies on pen input channels, i.e. the human ability to control the electronic pen input channels and interaction techniques with pen input channels, we propose two navigating techniques based on multiple pen input channels:(1) navigating technique based on pen tilt and rolling angle which control documentation’s scrolling and zooming,(2) navigating technique based on pen tilt angle and pressure which control documentation’s scrolling and zooming. In the experiment, the proposed navigating techniques are tested for text, picture and map navigating tasks. Comparing to standard scroll bar with traditional zooming methods and the Speed-dependent Automatic Zooming navigating manner [20] which shows a good performance, the proposed navigating techniques with multiple pen input channels have nice performances on speed, accuracy and participants’ preferences.
