Using motor tasks to quantitatively judge 3-D surface curvatures
Using motor tasks to quantitatively judge 3-D surface curvatures is a scholarly work by Frank E. Pollick and Jan Koenderink, published in 1999 in ''Attention, Perception and Psychophysics''. The main subjects of the publication include sensitivity, visual perception, geometry, mathematical analysis, somatosensory system, motor control, curvature, mathematics, surface, mean curvature, and principal curvature. The primary objective of this study was to quantitatively investigate the human perception of surface curvature by using virtual surfaces and motor tasks along with data analysis methods to estimate surface curvature from drawing movements.
