Natural and Smooth Pen-based Interaction Utilizing Multiple Pen Input Channels Chuanyi LIU Pen devices such as PDAs and Tablet PCs, are being used more and more widely because of the naturalness of pen input.Pen-based interaction is an important study field in human computer interfaces.Most pen-based computing devices support multiple input channels.These input channels enable pen-based devices to possess the potential of supporting natural and smooth operation.Natural interfaces allow users comfortably and easily interact with computing devices.Smooth operation has the potential of enhancing users' performance of performing interaction tasks on pen-based devices.WIMP (Windows, Icons, Menus and Pointing devices) interfaces are prevalent for decades in GUIs.However, WIMP interfaces are not completely suitable for pen-based systems, since WIMP interfaces are initially designed for mice and keyboards.This thesis focuses on exploring a pen suitable operation semantic and the related interaction techniques.A seamless and continuous operation semantic is proposed to enhance the traditional WIMP interfaces for pen-based applications.The proposed operation semantic is suitable for a common computer task, which can be typically divided into three phases, i.e. object selection, command selection and property setting phases.With the proposed operation semantic, a whole computer task from object selection to property setting can be performed in one stroke of a pen.An experiment was done to compare the proposed operation semantic and the standard operation methods in MS-Word 2007 in both Contents 4.4.1 Selecting 3D objects . . . . . . .
