There are many interface schemes that allow users to work at, and move between, focused
and contextual views of a dataset. We review and categorize these schemes according to …

This paper makes seven recommendations to HCI researchers wishing to construct Fitts' law
models for either movement time prediction, or for the comparison of conditions in an …

Target selection is a fundamental task in interactive Augmented Reality (AR) systems.
Predicting the intended target of selection in such systems can provide users with a smooth …

We present the bubble cursor-a new target acquisition technique based on area cursors.
The bubble cursor improves upon area cursors by dynamically resizing its activation area …

Although the power of personal computers has increased 1000-fold over the past 20 years,
user interfaces remain essentially the same. Innovations in HCI research, particularly novel …

Children are increasingly using computer technologies as reflected in reports of computer
use in schools in the United States. Given the greater exposure of children to these …

We introduce semantic pointing, a novel interaction technique that improves target
acquisition in graphical user interfaces (GUIs). Semantic pointing uses two independent …

We present a practical technique for pointing and selection using a combination of eye gaze
and keyboard triggers. EyePoint uses a two-step progressive refinement process fluidly …

Pointing tasks in human–computer interaction obey certain speed–accuracy tradeoff rules.
In general, the more accurate the task to be accomplished, the longer it takes and vice versa …

We survey recent research into new techniques for artificially facilitating pointing at targets in
graphical user interfaces. While pointing in the physical world is governed by Fitts' law and …
