Graphical Means of Directing User's Attention in the Visual Interface
This paper presents two experiments in using “masks” to direct users’ attention within a graphical user interface. Bleaching, darkening, blurring, and a solid-color pattern overlay (screening) are used to de-emphasize background material, causing the target to visually “pop-out” at the user. The tradeoff between effectively directing the user's attention and ensuring the readability of the back...
متن کاملDirecting visual attention during action observation modulates corticospinal excitability
Transcranial magnetic stimulation (TMS) research has shown that corticospinal excitability is facilitated during the observation of human movement. However, the relationship between corticospinal excitability and participants' visual attention during action observation is rarely considered. Nineteen participants took part in four conditions: (i) a static hand condition, involving observation of...
متن کاملA Maximum-Likelihood Strategy for Directing Attention during Visual Search
ÐA precise analysis of an entire image is computationally wasteful if one is interested in finding a target object located in a subregion of the image. A useful aattention strategyo can reduce the overall computation by carrying out fast but approximate image measurements and using their results to suggest a promising subregion. This paper proposes a maximum-likelihood attention mechanism that ...
متن کاملDirecting Attention in Open Scenes
Attention direction is particularly difficult in open scenes such as detailed aerial photographs, wide angle/multiple video feeds, or high-resolution digital imagery. Unlike conventional displays that have single parameters with definable set points, open scenes lack easy criteria for directing attention. The present study investigates the effects of varying levels of highlighting for correctly...
متن کاملAttention Issues in Spatial Information Systems: Directing Mobile Users' Visual Attention Using Augmented Reality
Knowledge of objects, situations, or locations in the environment can be productive, useful, or even life-critical for mobile augmented reality (AR) users. Users may need assistance with (1) dangers, obstacles, or situations requiring attention; (2) visual search; (3) task sequencing; and (4) spatial navigation. The omnidirectional attention funnel is a general purpose AR interface technique th...
