Survey on haptic rendering of data sets: Exploration of scalar and vector fields
نویسندگان
چکیده
Complementary to automatic extraction processes, Virtual Reality technologies provide an adequate framework to integrate human perception in the exploration of large data sets. In such multisensory system, thanks to intuitive interactions, a user can take advantage of all his perceptual abilities in the exploration task. In this context the haptic perception, coupled to visual rendering, has been investigated for the last two decades, with significant achievements. In this paper, we present a survey related to exploitation of the haptic feedback in exploration of large data sets. For each haptic technique introduced, we describe its principles and its effectiveness.

Interactive Exploration of Volumetric Data Sets With a Combined Visual and Haptic Interface
The analysis of complex volumetric data sets is a critical component of many scientific and engineering applications. The difficulty of understanding the increasing amount of data generated by these applications motivates the need for effective and intuitive visualization approaches that allow users to extract relevant information from the data in a relatively short amount of time. Even though ...
متن کاملHaptic Navigation in Volumetric Datasets
Methods of direct or indirect volume rendering are well established and helpful tools for the interactive visual exploration of volumetric datasets. However, the usual display is oriented on surface information, such as the surface of volumetric objects. The actual volumetric information is difficult to interpret intuitively with solely visual methods. In this paper, we add a haptic cue to impr...
متن کاملCasimir effects of nano objects in fluctuating scalar and electromagnetic fields: Thermodynamic investigating
Casimir entropy is an important aspect of casimir effect and at the nanoscale is visible. In this paper, we employ the path integral method to obtain a general relation for casimir entropy and internal energy of arbitrary shaped objects in the presence of two, three and four dimension scalar fields and the electromagnetic field. For this purpose, using Lagrangian and based on a perturb...
متن کاملA Direct Volume Rendering Framework for the Interactive Exploration of Higher-Order and Multifield Data
Direct Volume Rendering is a popular method for displaying volumetric data sets without generating intermediate representations. The technique is most frequently applied to scalar data and few specialized techniques exist for visualizing higher-order data, such as tensor fields, directly. This is a serious limitation because progress in medical imaging, satellite technology and numerical simula...
متن کاملHaptic Rendering of Data on Irregular Grids
Haptic rendering of data on irregular grids requires additional data storage and real time computation compared to the same size data sets on regular grids. At the same time, it is important to keep computation time small to avoid noticeable artifacts in haptic rendering. When the rendering algorithm is implemented on DSP processors, memory is often much smaller than on contemporary general pur...
