Sketching Temporal Uncertainty - An Exploratory User Study
(The Eurographics Association, 2018)
Real world datasets frequently contain inherent uncertainty of some kind. Most of the work in the context of visualizing temporal uncertainty, focus on evaluating and comparing different visualization approaches. This ...
Visual Analysis of Geo-spatial Data in 3D Terrain Environments using Focus+Context
(The Eurographics Association, 2017)
Visual analysis of geo-spatial data represented within a three-dimensional frame of reference is a challenging task. Focus+ Context is a common concept that aids this process. This paper addresses the question, how ...
User-study Based Optimization of Fast and Accurate Mahalanobis Brushing in Scatterplots
(The Eurographics Association, 2017)
Brushing is at the heart of most modern visual analytics solutions with coordinated, multiple views and effective brushing is crucial for swift and efficient processes in data exploration and analysis. Given a certain data ...
Categorizing Uncertainties in the Process of Segmenting and Labeling Time Series Data
(The Eurographics Association, 2018)
The segmenting and labeling of multivariate time series data is applied in different domains, e.g. activity recognition or sensor states. This involves several steps of (pre-) processing, segmenting, and labeling of time ...
Comparative Evaluation of Sensor Devices for Micro-Gestures
(The Eurographics Association, 2017)
This paper presents a comparative evaluation of two gesture recognition sensors and their ability to detect small, movements known as micro-gestures. In this work we explore the capabilities of these devices by testing if ...
Visually Exploring Data Provenance and Quality of Open Data
(The Eurographics Association, 2018)
While open data platforms are increasingly popular among end-users as well as data providers, there is a growing problem with inconsistent update frequencies and lack of quality in datasets. Efforts to monitor data quality ...
Exploring Interactive Linking Between Text and Visualization
(The Eurographics Association, 2018)
Visualizations are included in documents as augmentation to text and they become more intuitive if readers have the ability to interact with them. Modern web technologies facilitate the development of interactive documents ...
ConTraffic Visual Analytics in Support to Customs Risk-Analysis
(The Eurographics Association, 2017)
Customs risk analysis is crucial for detecting fraud and contraband goods in the massive flows of internationally traded goods. Most of non-bulk goods are transported in shipping containers and, as customs can control only ...
Characterizing User Behavior for Speech and Sketch-based Video Retrieval Interfaces
(Association for Computing Machinery, Inc (ACM), 2017)
From a user interaction perspective, speech and sketching make a good couple for describing motion. Speech allows easy speci cation of content, events and relationships, while sketching brings in spatial expressiveness. ...
Tactile Representation of Image in a Plane Actuator
(The Eurographics Association, 2017)
Our study investigated the effect of vibration elements on the recognition of texture in a planar type actuator. A planar type actuator is highly advantageous in naturally conveying the texture of a graphic object on a ...
