Spatial Visualization in Two vs. Three Dimensions
نویسندگان
چکیده
Several studies (e.g. Kerr, 1987; 1993; Diwadkar, Carpenter & Just, 2000) have asked participants to report the final location of a point after imaginary moves through 2D and 3D arrays. The results suggest that visualizing 3D space is inherently more difficult than 2D visualization, and may even use different brain mechanisms. However, 2D and 3D trials were presented in separate blocks, so participants could have developed different strategies for 2D and 3D cases. Here we reduce this risk by presenting randomly intermixed 2D and 3D trials. To further enforce the use of spatial memory, we use a new technique (path visualization, PV, Lyon, Gunzelmann, & Gluck, 2004) that taps information about the whole path.

Bringing CLARITY to the human brain: visualization of Lewy pathology in three dimensions
AIMS CLARITY is a novel technique which enables three-dimensional visualization of immunostained tissue for the study of circuitry and spatial interactions between cells and molecules in the brain. In this study, we aimed to compare methodological differences in the application of CLARITY between rodent and large human post mortem brain samples. In addition, we aimed to investigate if this tech...

متن کاملVolume modeling of soils using GRASS GIS 3D-Tools
The analysis of spatial variability of soils has been of interest to soil scientists and geographers for quite some time. Information on soil properties are usually available from a limited number of point measurements and spatial estimates are prepared in two dimensions (e.g. by interpolation or other technique). However, soil is essentially a 3D object with varying properties in all spatial d...

متن کاملVisualizations for High Dimensional Data Mining - Table Visualizations
Visualizations that can handle flat files, or simple table data are most often used in data mining. In this paper we survey most visualizations that can handle more than three dimensions and fit our definition of Table Visualizations. We define Table Visualizations and some additional terms needed for the Table Visualization descriptions. For a preliminary evaluation of some of these visualizat...
