Perception of Gradient in Haptic Graphs: a Comparison of Virtual and Physical Stimuli
نویسندگان
چکیده
We report an experiment in which people were asked to make a judgement about the gradient of a simple line graph. As part of the MultiVis project on data visualisation for blind people our aim was to discover how accurately linear graphs can be rendered using relatively simple technology: raised paper, and a haptic force-feedback mouse. Results show that both media allowed very accurate performance.

متن کاملTracing Tubular Objects in 3D Confocal Images Using Haptic Device
Blood capillaries in brain [5] and skeletal muscle [1] can be visualized and studied in 3D by confocal microscopy. 3D data enable direct analysis of the geometric properties of complex networks by image analysis techniques. The graphs of capillaries that cannot be detected automatically due to low contrast, high noise or complicated background but are clearly visible can still be digitized manu...
متن کاملPerception of Physical Properties with Augmented Auditory-Tactile Feedback Master Thesis
By means of Augmented Reality systems it has become increasingly easy to add virtual objects to our reality and interact with them. But AR can also be utilized to change real objects, i.e. our perception of real objects. In this thesis we present two methods for changing how we perceive thickness when we are exploring objects by touch; by modulating auditoryand tactile feedback. Vision being a ...
