Poster: Scattering and Jittering: Using Real and Illusionary Motion for Better Visual Scatterplot Analysis

چکیده
A scatterplot is one of the most popular techniques used for visualizing multidimensional datasets. However, if the number of data points is large, occlusion and overdraw problems occur. Thus, it will be difficult to visually differentiate these data points and their clusters. Motion is one of the strongest low-level perceptual cues to draw our visual system’s attention to a certain subset of data. In this paper, we present three approaches that use different motion concepts to improve the identification and separation of precomputed clusters in scatterplots. First, we present two techniques generating real motion effects by the use of flickering and by the use of different weaving patterns. Furthermore, we present a technique using mimic motion by the use of peripheral drift.

Quality Metrics Driven Approach to Visualize Multidimensional Data in Scatterplot Matrix
Extracting meaningful information out of vast amounts of high-dimensional data is challenging. Prior research studies have been trying to solve these problems through either automatic data analysis or interactive visualization approaches. Our grand goal is to derive representative and generalizable quality metrics and to apply these to amplify interesting patterns as well as to mute the uninter...
متن کاملNew adaptive interpolation schemes for efficient meshbased motion estimation
Motion estimation and compensation is an essential part of existing video coding systems. The mesh-based motion estimation (MME) produces smoother motion field, better subjective quality (free from blocking artifacts), and higher peak signal-to-noise ratio (PSNR) in many cases, especially at low bitrate video communications, compared to the conventional block matching algorithm (BMA). Howev...
متن کاملGlobal-perspective jitter improves vection in central vision.
Previous vection research has tended to minimise visual-vestibular conflict by using optic-flow patterns which simulate self-motions of constant velocity. Here, experiments are reported on the effect of adding 'global-perspective jitter' to these displays--simulating forward motion of the observer on a platform oscillating in horizontal and/or vertical dimensions. Unlike non-jittering displays,...
متن کاملGatherplots: Generalized Scatterplots for Nominal Data
Overplotting of data points is a common problem when visualizing large datasets in a scatterplot, particularly when mapping nominal dimensions to one of the scatterplot axes. Transparency, aggregation, and jittering have previously been suggested to address this issue, but these solutions all have drawbacks for assessing the data distribution in the plot. We propose gatherplots, an extension of...
متن کاملHydrodynamic damped pitch motion of tension leg platforms
Because of fluctuation in leg tension, pitch motion is very effective fatigue and life safety of leg elements in tension leg structures (TLSs). In this paper an exact solution for pitch vibration of a TLS interacting with ocean wave is presented. The legs of TLP are considered as elastic springs. The flow is assumed to be irrotational and single-valued velocity potentials are defined. The effec...
