Core Concepts
Designing and developing data visualizations for large displays presents unique challenges that require specialized considerations.
Abstract
1. Introduction
Growing data sizes make visualizing complex data challenging.
Large displays (LDs) are essential for presenting complex data.
Challenges include design principles, encoding effectiveness, and visualization types.
2. Methodology
Semi-structured interviews with experts conducted online.
Participants had experience in LDs and data visualization.
Data analyzed using the affinity diagram technique.
3. Preliminary Findings
3.1 Limited Resources for Building LD Infrastructure
Challenges in space allocation and cooling systems.
Sharing demos due to immobility of LDs poses difficulties.
3.2 Scaling Data Visualization Designs for LDs
Disparity in sizes makes sketching designs challenging.
Need for specific tools like flip charts to simulate LD dimensions.
3.3 Limited Development Resources and Tools for LDs
Prototyping away from LDs requires constant checks.
Specialized interactions needed for LDs pose challenges.
3.4 Evaluating Data Visualizations on LDs with People
Unfamiliarity with LD technology hinders evaluation process.
Difficulties in switching between devices impact productivity.
4. Discussion
Identifies challenges faced by designers and developers working on LD data visualizations.
Importance of tailored approaches to address these challenges emphasized.
Stats
LD環境は、探索プロセス中に複数のビューを表示および並置するための豊富なスペースを提供します。
デスクトップサイズのディスプレイとは異なり、LDは大画面サイズで操作するための専門的なインタラクション技術を必要とします。
評価プロセス中に、人々がキーボードと画面間を切り替えることに苦労していることが報告されています。
Quotes
"Usually we moved all the chairs and tables because my research was focusing on making people like [minimum] three people to collaborate in their room and use the large display in an environment so they can explore the data." - Participant 1
"What we did, which would just get flipchart paper, which, like one and a half flipchart paper, kind of corresponded to what we had in the screen wise for one screen, right? So you could then essentially tape, so we could take the whole wall with it and we had the wall that was big enough to actually simulate [the LD] . . . So later, we had a wall and like 4 flipchart stands as well so that you can do the curve thing as well. It looked pretty silly, but it was actually very effective." - Participant 3
"I didn’t get too much help from . . . just in that because this is like a very specific platform that I needed." - Participant 4
