HotSketch: Drawing Police Patrol Routes among Spatiotemporal Crime Hotspots
During the course of a day, a police unit is expected to move throughout the city to provide a visible presence and respond quickly to emergencies. Planning this movement at the beginning of the shift can provide a helpful first step in ensuring that officers are present in areas of high crime, but these plans can quickly break down as they are pulled away to 911 calls. Once such an initial plan is deferred, police units need to be able to rapidly and fluidly decide where to go next depending on their immediate location and time. In this paper, we present our research to couple spatiotemporal analysis of historical crime data with sketch-based interaction methods. This research is presented through an initial prototype, HotSketch, which we describe through a set of use cases within the domain of police patrol route planning
Understanding and Measuring the Effects of Graphical Dimensions on Viewers' Perceived Chart Credibility
Journalists and visualization designers include visualizations in their
articles and storytelling tools to deliver their message effectively. But
design decisions they make to represent information, such as the graphical
dimensions they choose and the viewer's familiarity with the content can impact
the viewer's perceived credibility of charts. Especially in a context where
little is known about sources of online information. But there is little
experimental evidence that designers can refer to make decisions. Hence, this
work aims to study and measure the effects of graphical dimensions and people's
familiarity with the content on viewers' perceived chart credibility. I plan to
conduct a crowd-sourced study with three graphical dimensions conditions, which
are traditional charts, text annotation, and infographics. Then I will test
these conditions on two user groups, which are domain experts and non-experts.
With these results, this work aims to provide chart guidelines for visual
designers with experimental evidence.Comment: Published in PacificVis2023, Poste
10241 Abstracts Collection -- Information Visualization
From 13.06.10 to 18.06.10, the Dagstuhl Seminar 10241 ``Information Visualization \u27\u27 was held in Schloss Dagstuhl~--~Leibniz Center for Informatics.
During the seminar, several participants presented their current
research, and ongoing work and open problems were discussed. Abstracts of
the presentations given during the seminar as well as abstracts of
seminar results and ideas are put together in this paper. The first section
describes the seminar topics and goals in general.
Links to extended abstracts or full papers are provided, if available
10241 Executive Summary -- Information Visualization
Information Visualization (InfoVis) focuses on the use of
visualization techniques to help people understand and analyze
data. While related fields such as Scientific Visualization involve
the presentation of data that has some physical or geometric
correspondence, Information Visualization centers on abstract
information without such correspondences.
The aim of this seminar was to bring together theoreticians
and practitioners from the field with a special focus on the
intersection of InfoVis and Human-Computer Interaction. To support
discussions that are related to the visualization of real world
data, researchers from selected application areas also attended and
contributed. During the seminar, working groups on eight different
topics were formed and enabled a critical reflection on
ongoing research efforts, the state of the field, and key research
challenges today
07221 Executive Summary - Information Visualization - Human-Centered Issues in Visual Representation, Interaction, and Evaluation
Information Visualization (InfoVis) focuses on the use of visualization techniques to help people understand and analyze data. While related fields such as Scientific Visualization involve the presentation of data that has some physical or geometric correspondence, Information Visualization centers on abstract information without such correspondences.
One important aim of this seminar was to bring together theoreticians and practitioners from Information Visualization and related fields as well as from application areas. The seminar has allowed a critical reflection on actual research efforts, the state of field, evaluation challenges, etc. This document summarizes the event
