5. Dimensions | What is the intrinsic number of dimensions (not necessarily spatial) in your data, and how many do you want to show at once?


By “dimensions,” we do not necessarily mean spatial dimensions… xxAG explain, Arzu-you can read Goodman 2012 to know more about what I meant “non-spatially”xx

 

Many empirical studies suggest that 3D visualizations lead to more mistakes and they slow people down, even when the nature of nearly all phenomena is 3D (Borkin***, Dall’acqua****, unpublished stereo visual search task, others). This desire to stay true to the nature of the phenomenon does not always pay off (also true for continuous and discrete colors, see Dall’acqua***). The tasks that require searching, counting, comparing (such as detecting anomalies, estimating distances, reading information from a plot) appears to suffer from information overload for the short term working memory. What is not yet clearly understood is the mid-term and long term effects of the 3D and realistic visualizations for a global recognition and understanding of the represented phenomena; as well as the its impact in the mid and long term memory (e.g., learning). Some studies suggest it may be improving scores in exams e.g., in comparison to text-only studying (Mahrer & Coltekin***).
