The existing efforts in computer assisted semen analysis have been focused on high speed imaging and automated image analysis of sperm motility. This results in a large amount of data, and it is extremely challenging for both clinical scientists and researchers to interpret, compare and correlate the multidimensional and time-varying measurements captured from video data. In this work, we use glyphs to encode a collection of numerical measurements taken at a regular interval and to summarize spatio-temporal motion characteristics using static visual representations. The design of the glyphs addresses the needs for (a) encoding some 20 variables using separable visual channels, (b) supporting scientific observation of the interrelationships between different measurements and comparison between different sperm cells and their flagella, and (c) facilitating the learning of the encoding scheme by making use of appropriate visual abstractions and metaphors. As a case study, we focus this work on video visualization for computer-aided semen analysis, which has a broad impact on both biological sciences and medical healthcare. We demonstrate that glyph-based visualization can serve as a means of external memorization of video data as well as an overview of a large set of spatiotemporal measurements. It enables domain scientists to make scientific observation in a cost-effective manner by reducing the burden of viewing videos repeatedly, while providing them with a new visual representation for conveying semen statistics.

“…O VER the past decade, researchers have demonstrated the usefulness of video visualization through applications such as surveillance [23], [16], sports analysis [58] and entertainment [24], [49]. In biology today, videos are used extensively to capture motile cells, many of which exhibit a tail-like appendage called a flagellum.…”

“…The selection of key-frames and their relationship to the semantics of the perceived action is explored in depth by Whitaker and Halas [46]. Several researchers [19,32,34] have proposed illustration-based techniques to depict the dynamics of time-varying data in a compact way. Using principles inspired by visual art they generate one or a few images that are augmented by illustrative glyphs to visually communicate time-varying data.…”

“…For instance, Joshi and Rheingans [19] have presented a method to convey change over time using illustration-inspired techniques such as the use of speedlines, flow ribbons, and strobe silhouettes. Nienhaus and Dollner [32] have used dynamic glyphs such as directed acyclic graphs and behavior graphs to provide further information about dynamics in the 3D scene.…”

Contemporary molecular dynamics simulations result in a glut of simulation data, making analysis and discovery a difficult and burdensome task. We present MDMap, a system designed to summarize long-running molecular dynamics (MD) simulations. We represent a molecular dynamics simulation as a state transition graph over a set of intermediate (stable and semi-stable) states. The transitions amongst the states together with their frequencies represent the flow of a biomolecule through the trajectory space. MDMap automatically determines potential intermediate conformations and the transitions amongst them by analyzing the conformational space explored by the MD simulation. MDMap is an automated system to visualize MD simulations as state-transition diagrams, and can replace the current tedious manual layouts of biomolecular folding landscapes with an automated tool. The layout of the representative states and the corresponding transitions among them is presented to the user as a visual synopsis of the long-running MD simulation. We compare and contrast multiple presentations of the state transition diagrams, such as conformational embedding, and spectral, hierarchical, and force-directed graph layouts. We believe this system could provide a road-map for the visualization of other stochastic time-varying simulations in a variety of different domains.

“…Model-based feedback could include, e. g., semitransparent hulls or object coloring, arrows, flags, etc. as temporary landmarks, glyphs for showing directions [21], or labels for scene annotation [19]. Image-based feedback could comprise, e. g., lines or bread crumbs for path representations [10], blending pictograms, labeling on the view plane, using halos for distance indications, or picture-in-picture visualization.…”

Navigation represents a fundamental interaction technique for 3D virtual environments (3DVEs) -it enables users to explore the virtual world and to interact with its objects. For this, effective navigation techniques are required that take into account users and their goals. They also should prevent common problems of 3D navigation, such as an intricate camera control or "getting-lost" situations due to incoherent and confusing camera views. Smart navigation aims at this category of navigation techniques; it represents a special type of smart interaction and, thus, an essential element of smart graphics. This article presents the conceptual building blocks of smart navigation for 3DVEs and describes a navigation technique that allows for specifying navigation commands by sketches and gestures: Users sketch their navigation intentions on top of the perspective projection of the 3D scene; the system interprets these sketches regarding the affected scene geometry, as well as the spatial and temporal context. Based on this interpretation, navigation activities are derived and automatically performed. By providing assistance and automation, the smart navigation approach can substantially simplify user interfaces for 3DVEs and, thus, represents an essential component for novel applications of 3DVEs, e. g., based on touchsensitive displays.
