Immersive analytics and data visualization (Erica Stella PhD-INF)
The starting point of the search was using “data visualization” as a keyword, but it yielded results in the thousands (WOS=7k; Scopus=56k; Google Scholar=403k), mainly in the computer science field.
Then, since I’m looking for visualizations of dimensionally-reduced data, I refined the search by introducing “dimensionality reduction” as a keyword. This reduced significantly the number of results (WOS=234; Scopus=2300). However, looking at the first results, the articles concerned mainly bidimensional visualizations, which are not extremely useful in the context of virtual reality. Accordingly, I further refined my search by adding “three dimensional” as a keyword. This yielded few results (WOS=5; Scopus=187) but highly pertinent. One further step would be to identify relevant surveys published recently.
I also looked for “immersive analytics”, which proved to be a field with relatively few contributions (WOS=47; Scopus=250), mainly in the last 5 years and close to none in the previous two decades. An extensive survey comprising papers from 1991 up to 2018 was published last year. Transactions on Visualizations and Computer Graphics and IEEE VR are the main publication venues. Then, I tried to add the previously used “dimensionality reduction” keyword to refine the search. It yielded 250 apparently useful (at least at a first glance of the most relevant) results in Scopus. However, WOS only returned 1 result which was not pertinent. I did not try the “three dimensional” keyword since it is implicit in the concept of “immersive”.
