Data Materialization: A Hybrid Process for Crafting a Teapot

Data materialization is a workflow developed to create 3D objects from data-informed designs. Building upon traditional metalwork and craft, and new technology's data visualization with generative art, this workflow expresses conceptually relevant data through 3D forms which are fabricated in traditional media. The process allows for the subtle application of data in visual art, allowing the aesthetic allure of the art object or installation to inspire intellectual intrigue. This paper describes the technical and creative process of Modern Dowry, a silver-plated 3D-print teapot on view at the Museum of the City of New York, June 2017--June 2018.Museum of the City of New York; Jeannine Falino; the National Science Foundation for supporting the Computing in the Arts workshops (DUE 1323610, DUE 1323605, DUE 1323593); Reiser’s fellow principle investigators (Bill Manaris, Renee McCauley, Jennifer Burg and Rebecca Bruce); Seton Hall University’s Digital Humanities Fellowship Program for funding and support; and Vassar College’s Creative Arts Across Disciplines Program for their summer residency and exceptional collegiality

NONLINEAR APPROACH IN CLASSIFICATION VISUALIZATION AND EVALUATION

In this paper we have proposed the novel methodology to visualize classification scheme in informatics domain. We have mapped a documents collection of ACM (Association for Computing Machinery) Digital Library to a sphere surface. Two main stages of visualization processes complement one another: classification and clusterization. Primarily classified documents were visualized and their further clusterization by means of keywords was crucial in evaluation process. For clusters analysis of given visualization maps nonlinear digital filtering techniques were applied. The clusters of keywords were characterized by a local accuracy. Obtained semantic map was included to validation process

Visualizing the scientific information nowadays: the problems and challenges

In recent years, a comparably fresh research field — information visualization has become commonly available for the researchers of all specialties. Information or knowledge maps play a role of interface for the analysis and intensive study of scientific community and knowledge domains development. The popularity of visualization techniques and interdisciplinary framework has resulted in many problems that have not been solved since the field had emerged. The article introduces the instrumental problems and challenges in this field. Exposing the functions information visualization allows to understand the difficulties and barriers within the whole visualizing process. A particular example of insight into the Polish science map is considered in the context of a new knowledge

트리 구조를 이용한 3차원 공간 내 데이터 시각화 연구

학위논문 (박사)-- 서울대학교 대학원 : 미술대학 디자인학부 디자인전공, 2019. 2. 김수정.Speculative visualization combines both data visualization methods and aesthetics to draw attention to specific social, political and environmental issues. The speculative data visualization project proposed in this work explores electronic waste trade and the environmental performance of various nations. Illegal trading of electronic waste without proper disposal and recycling measures has a severe impact on both human health and the environment. This trade can be represented as a network data structure. The overall environmental health and ecosystem vitality of those trading countries, represented by their Environmental Performance Index (EPI), can also give greater insight into this issue. This EPI data has a hierarchical structure. This work explores methods to visualize these two data sets simultaneously in a manner that allows for analytical exploration of the data while communicating its underlying meaning. This project-based design research specifically focuses on visualizing hierarchical datasets with a node-link type tree structure and suggests a novel data visualization method, called the data garden, to visualize these hierarchical datasets within a spatial network. This draws inspiration from networks found between trees in nature. This is applied to the illegal e-waste trade and environmental datasets to provoke discussion, provide a holistic understanding and improve the peoples awareness on these issues. This uses both analytical data visualization techniques, along with a more aesthetic approach. The data garden approach is used to create a 3D interactive data visualization that users can use to navigate and explore the data in a meaningful way while also providing an emotional connection to the subject. This is due to the ability of the data garden approach to accurately show the underlying data while also closely mimicking natural structures. The visualization project intends to encourage creative professionals to create both visually appealing and thought-provoking data visualizations on significant issues that can reach a mass audience and improve awareness of citizens. Additionally, this design research intends to cause further discussion on the role of aesthetics and creative practices in data visualizations.사변적 시각화(speculative visualization)는 데이터 시각화 방법과 미학을 결합하여 특정한 사회, 정치 및 환경 문제에 관심을 유도하는 것입니다. 제안한 사변적 데이터 시각화 프로젝트를 통해 다양한 국가의 전자 폐기물 거래와 환경 성과를 살펴봅니다. 적절한 처리와 재활용 조치가 이뤄지지 않은 전자폐기물의 불법 거래는 환경과 인간에 심각한 영향을 미칩니다. 이 거래는 네트워크 데이터 구조로 표현할 수 있습니다. 환경성과지수(EPI)를 통해 이 거래에 참여하는 국가들의 전반적인 환경 보건과 생태계 활력을 살펴보는 것은 이 문제에 더 깊은 통찰력을 제공할 수 있습니다. 이 환경성과지수는 계층 구조로 되어 있습니다. 이 연구는 데이터를 분석적으로 탐구할 수 있도록 하는 방법을 통해 두 가지 데이터를 동시에 시각화하고, 이를 통해 표면에 드러나지 않는 데이터의 의미를 전달하는 방법을 탐구합니다. 본 연구는 프로젝트를 기반으로 하는 디자인 연구로, 노드 링크 유형 트리 구조를 통해 계층적 데이터를 시각화하는 것에 중점을 두고 있습니다. 자연에서 발견할 수 있는 나무 간 네트워크에서 영감을 얻어 공간 네트워크에서 계층적 데이터 세트를 시각화합니다. 데이터 정원이라고 하는 이 새로운 데이터 시각화 방법을 불법 전자 폐기물 거래와 환경 데이터에 적용하여 토론을 유발하고 전체적인 이해를 제공하며 이러한 문제에 대한 사람들의 인식을 개선하고자 합니다. 이는 보다 미적인 접근과 분석적 데이터 시각화 기술을 모두 사용합니다. 데이터 정원을 통한 접근으로 삼차원 대화형 데이터 시각화를 만들 수 있습니다. 이 시각화를 통해 사용자는 데이터를 의미 있는 방식으로 살펴보는 동시에 주제와 감성적인 연결을 받을 수 있습니다. 이는 데이터 정원 방법이 데이터를 정확하게 보여주는 동시에 자연 구조를 면밀하게 모방하기 때문입니다. 본 시각화 프로젝트는 창의적인 전문가들이 중요한 문제에 대해 시각적으로 매력적이고 생각을 자극하는 데이터 시각화를 만들어 대중에게 도달하고 시민들의 인식을 향상할 수 있도록 권장합니다. 또한, 본 디자인 연구는 데이터 시각화에서 미학과 창조적인 실천의 역할에 대한 더 많은 논의를 유도하고자 합니다.Abstract I Table of Contents III List of Figures VI 1.

Designing Controversies and their Publics

Controversy mapping is a teaching and research method derived from the Science and Technology Studies and meant to explore and represent modern sociotechnical issues. Striving to make the intricacy of scientific debate readable for a larger public, controversy mapping is trapped in a classic simplicity/complexity trade-?‐off: how to respect the richness of controversies without designing maps too complicated to be useful? Having worked on the question for almost two years in a project bringing together social scientists and designers (emapsproject.com1), we can now propose a way out of this contradiction and suggest three ways of moving through the simplicity/complexity continuum. The first movement -?‐by multiplying the number of maps and by taking into account users before the beginning and after the end of the design process-?‐ allows to bypass the simplicity/complexity trade-?‐off. The second movement bind together narration and exploration and allows the publics to venture in the maze of controversies unraveling the story that will guide them out. The third movement allows to involve the publics through all the phases of a cartographic campaign and to engage it again and again

The role of the audience in contemporary data art

As a new form of contemporary art, data art has changed the audience’s artistic experience. This paper first introduces the characteristics of data art which are different from other contemporary art. Secondly, in the context of public participation in art, it explores how data art enables audiences to participate in various stages of artistic creation, so that audiences can become one of the creators rather than mere art connoisseurs. Finally, it summarizes participatory issues in different stages of data art

Teaching Tip: Evaluating Visualizations with a Compact Rubric

Students now have readily available and powerful tools to access, manipulate, combine, and visualize data. Acquiring data and visual literacy requires more than knowledge of how to use these tools. Students need to engage with assignments that challenge them to make relatively complex visualizations, interpret them, and explain why these interpretations matter for given problem situations. This paper describes how to structure feedback for these assignments. The few published visualization evaluation rubrics are mainly oriented toward how-to-do-it heuristics. This paper makes a contribution by presenting, defining, and giving examples of the use of an innovative compact rubric for evaluating visualizations (CRVE). This rubric eliminates some of the length and complexity of heuristic evaluation, focusing on interpretation and relevance. In a graduate business intelligence course, students showed definite improvement over the course of the semester in the construction of visualizations, telling a story with headlines, and striving for data exploration. However, higher levels of technical correctness of visualizations did not necessarily correspond to better interpretations. This finding underscores the importance of emphasizing interpretation through a feedback mechanism like the CRVE presented here

A Visual Analysis of EHR Flowsheet to Assist Clinicians’ Interpretation of Health-related Data

This project designed and implemented visualization interface of EHR Systems based on the requirements of the doctors. The visualizations combined both clinic-reported data and patient self-reported data to provide a better representation of patient health related information for the doctor to make decisions. The visualizations highlighted the trend of values, the outliers and make it possible to compare across time and measures. The user study of ten participants suggests that the visualization interface helped them find the information in an efficient way.Master of Science in Information Scienc
