摘要

可视化对于理解信息变得越来越重要,例如调查数据(例如:计算、医疗和犯罪现场证据)和分析(例如,网络能力评估、数据文件重建和规划场景)。调查性数据可视化用于重建场景或项目,并用于帮助观众(他们可能是对主题知之甚少或根本不了解的普通公众)理解所呈现的内容。另一方面,分析可视化通常是为那些通常对主题有理解的人开发的,用于审查数据、信息和评估相互竞争的情景假设。法庭环境正在演变成电影般的展示环境,媒体被越来越具有视觉素养和媒体悟性的观众所消费(Heintz, 2002)。从口头向视觉调解的转变有许多内在的基本含义,需要对这种现代证据呈现技术的许多方面进行调查和分析。可视化的一个主要问题是,无论数据多么连贯,总是会有关于信息如何被可视化,以及它是否以一种可接受和有意义的方式呈现的猜测和争论。本文介绍了一系列使用各种技术和技术将法医数据可视化的例子,然后研究了可视化法庭证据的各个方面,并讨论了实施这项技术的一些好处和潜在问题。本文是由两部分组成的系列文章的第二部分,该系列文章旨在描述在法庭中使用图形显示器并提供指导方针。

Technology Corner: Visualising Forensic Data: Evidence Guidelines (Part 2)
Visualisation is becoming increasingly important for understanding information, such as investigative data (for example: computing, medical and crime scene evidence) and analysis (for example, network capability assessment, data file reconstruction and planning scenarios). Investigative data visualisation is used to reconstruct a scene or item and is used to assist the viewer (who may well be a member of the general public with little or no understanding of the subject matter) to understand what is being presented. Analysis visualisations, on the other hand, are usually developed to review data, information and assess competing scenario hypotheses for those who usually have an understanding of the subject matter. Courtroom environments are morphing into cinematic display environments, the media consumed by an audience who are increasingly visually literate and media savvy (Heintz, 2002). There are a number of fundamental implications inherent in the shift from oral to visual mediation and a number of facets of this modern evidence presentation technology needs to be investigated and analysed. One of the primary issues of visualisation is that no matter how coherent the data, there will always be conjecture and debate as to how the information is/has-been visualised and, is it presented in an acceptable and meaningful way. This paper presents a range of examples of where forensic data has been visualised using various techniques and technology, the paper then examines aspects of the visual courtroom evidence presented and discusses some of the benefits and potential problems of implementing this technology. This paper is part two of a two-part series that aims to describe the use of, and provide guidelines for, the use of graphical displays in courtrooms.
