Study of Visual Clutter in Geographic Node-Link Diagrams
… information. For this purpose, the most common visual representation is the node-link diagram, where vertices are depicted as points and the edges connecting them are drawn as lines. This Thesis focuses on an instance of node-link diagrams, where nodes are over-imposed on a map and fixed …

Visual Clutter Study for Pedestrian Using Large Scale Naturalistic Driving Data
… during driving is a complex cognitive activity. Visual clutter analysis can be used to study the factors that affect human visual search efficiency and help design advanced driver assistant system for better decision making and user experience. In this thesis, we propose the pedestrian perception …

DesignEye : a tool for design teams to analyze and address visual clutter
… Science Group at MIT. Our tool computes the clutter of images and identifies the most salient visual elements, and allows designers to work with the softare in a tight iterative feedback loop to ensure that the most important design elements garner the most end-user attention. DesignEye is …

Developing an Augmented Reality Visual Clutter Score Through Establishing the Applicability of Image Analysis Measures of Clutter and the Analysis of Augmented Reality User Interface Properties
… of information atop the real world, this extra visual data potentially comes at a cost of increasing the visual clutter of the users' field of view, which can increase visual search time, error rates, and have an overall negative effect on performance. Visual clutter has been studied for …

Optimization of parallel coordinates for visual analytics
The visualization and interaction of multidimensional data always requires optimized solutions for integrating the display, exploration and analytical reasoning of data into a kind of visual pipeline for human-centered data analysis and interpretation. However, parallel coordinate plot, as one of …

Exploring the roles of display properties and display memorability in the contextual cueing task
… have been shown to predict response times in visual search experiments, including target eccentricity, target quadrant, visual crowding, and visual clutter. The effects of display properties may therefore limit the interpretability of contextual cueing effects that do not control for …

Evaluating the depiction of complex RNAV/RNP procedures and analyzing a potential de-cluttering technique
… increased information density and high levels of visual clutter. A total of sixty-three approach, fifty-two departure, and fifty-four arrival procedures were analyzed. Primary findings were that the factors associated with high levels of visual clutter included having multiple flight paths per …

Visual search asymmetries in complex geophysical displays
… such as geophysical maps can become heavily cluttered (e.g. Lohrenz, Trafton, Beck, & Gendron, 2009), hindering operators’ accurate detection of task-critical information. The use of visual search asymmetries (Treisman & Souther, 1985) in the design of display iconography might be an …

Street media : ambient messages in an urban space
… media often escape our notice - tuned out as visual clutter or dismissed as unimportant. Yet, attentive viewing and analysis reveal much about the local culture of communication and expression. This thesis blends empirical and theoretical methodologies in a year-long photographic study that …

An investigation of the relationship between typography and audio-based communication in the urban environment, with particular regard to pedestrian wayfinding
… It was also indicated that signage overload and visual clutter made pedestrian wayfinding problematic in the urban environment. Speculative design proposals investigate possible solutions to these issues. From this practical and theoretical basis guidelines have been derived with a view to …

Tracking dynamic regions of texture and shape
The tracking of visual phenomena is a problem of fundamental importance in computer vision. Tracks are used in many contexts, including object recognition, classification, camera calibration, and scene understanding. However, the use of such data is limited by the types of objects we are able to …

Children's Interface Design for Searching and Browsing
… and presentation keeps the screen from becoming cluttered, but requires a lot of navigation to explore categories in different areas and an understanding of potentially abstract high-level categories. Based on previous research with adults, I believed that a simultaneous presentation of a flat …

Inhibitory mechanisms for visual learning in the human brain
Identifying targets in cluttered scenes is critical for our interactions in complex environments. Our visual system is challenged to both detect elusive targets that we may want to avoid or chase and discriminate between targets that are highly similar. These tasks require our visual system to …

Adaptation in Non-Parametric State Estimation with Application to People Tracking
The employment of visual sensor networks in surveillance systems has brought in as many challenges as disadvantages. While the integration of multiple cameras into a network has the potential advantage of fusing complementary observations from sensors and enlarging visual coverage, it also …

Design and Interpretability of Contour Lines for Visualizing Multivariate Data
Multivariate geospatial data are commonly visualized using contour plots, where the plots for various attributes are often examined side by side, or using color blending. As the number of attributes grows, however, these approaches become less efficient. This limitation motivated the use of glyphs, …
