Facilitating pointing in graphical interfaces via kinematic analysis of user trajectories

在现代计算系统中，指向设备-笔、鼠标、跟踪点、触摸板-是无处不在的。这些设备允许用户通过与各种小部件交互来调用图形用户界面内的命令，即，在Windows Journal、GIMP、Photoshop和AutoCAD等程序中，定点设备也是信息输入的主要工具。鉴于GUI中指针设备的普遍性，如果我们了解人们如何操纵指针设备，我们就可以利用这种理解来开发更高效（使用更快）和可靠（防止错误）的界面。这项研究的目标是更全面地了解GUI中指向设备的运动。我们计划开发一个理解不同类型的运动在图形用户界面，指定这些不同类型的用户运动的数学模型，使用这些模型来识别背后的任何动作与指向设备的意图，最后，使用我们的理解意图设计新的智能交互技术。

In modern computing systems, pointing devices - a pen, a mouse, a trackpoint, a touchpad - are ubiquitous. These devices allow users to invoke commands within the Graphical User Interfaces by interacting with various widgets, i.e., by pressing a button, accessing a menu item, etc. In programs such as Windows Journal, the GIMP, Photoshop and AutoCAD, the pointing device also serves as the primary vehicle for information entry. Given the ubiquity of pointing devices in GUIs, if we understand how people manipulate pointing devices we can leverage this understanding to develop interfaces that are both more efficient (faster to use) and reliable (prevent errors). The goal of the research supported by this grant is to more fully understand the motion of pointing devices in GUIs. We plan to develop an understanding of the different types of motion in graphical user interfaces, to specify mathematical models of these different types of user motion, to use these models to recognize the intention behind any action with a pointing device, and, finally, to use our understanding of intention to design new intelligent interaction techniques.
