Improving Browsing Performance: A study of four input devices for scrolling and pointing tasks

چکیده
Navigating through online documents has become an increasingly common HCI task. This paper investigates alternative methods to improve user performance for browsing World Wide Web and other documents. In a task that involved both scrolling and pointing, we compared three input methods against the status-quo. The results showed that a mouse with a finger wheel did not improve user’s performance; two other methods, namely a mouse with an isometric rate-control joystick operated by the same hand and a two handed system that put a mouse on the dominant hand and a joystick on the other, both significantly improved users’ performance. A human factors analysis on each of the three input methods is also presented.

A model of scrolling on touch-sensitive displays
Scrolling interaction is a common and frequent activity allowing users to browse content that is initially off-screen. With the increasing popularity of touch-sensitive devices, gesture-based scrolling interactions (e.g., finger panning and flicking) have become an important element in our daily interaction vocabulary. However, there are currently no comprehensive user performance models for sc...
متن کاملExploring Vision-Based Interfaces: How to Use Your Head in Dual Pointing Tasks
The utility of vision-based face tracking for dual pointing tasks is evaluated. We first describe a 3-D face tracking technique based on real-time parametric motion-stereo, which is non-invasive, robust, and self-initialized. The tracker provides a real-time estimate of a “frontal face ray” whose intersection with the display surface plane is used as a second stream of input for scrolling or po...
متن کاملA study of two-handed scrolling and selection on standard notebook computers
Although two-handed input can improve both efficiency and quality of user interaction, it is not commonly adopted as it requires additional input devices. In this paper we propose two-handed interaction on standard hardware notebooks with external mouse and for a common task 2D scrolling. We introduce four techniques that leverage the built-in touchpad as a dedicated scrolling device for the no...

متن کاملSlideBar: Analysis of a linear input device
The SlideBar is a physical linear input device for absolute position control of one degree of freedom, consisting of a physical slider with a graspable knob positioned near or attached to the keyboard. Its range of motion is directly mapped to a one dimensional input widget such as a scrollbar. The SlideBar provides absolute position control in one dimension, is usable in the non-dominant hand ...
