Abstract:
In this paper we introduce an application for analyzing datasets obtained by scanning probe microscopy (SPM). Datasets obtained by such microscopes are typically depicted by two-dimensional images where the measured quantity (typically forces or electric current) is represented by pixel intensities of a rasterized image. Recording several images of this kind with one parameter being in- or decremented before recording the next image results in three-dimensional datasets. A conventional two-dimensional representation of such data by visualizing an axis-aligned slice cutting through the 3D data seems insufficient, since only a fraction of the available data can be examined at once. To improve the understanding of the measured data we propose utilizing a haptic device with four different real-time haptic models (collision, force, vibration and viscosity) in order to reinterpret nano surfaces in an intuitive way. This intuition is furthermore improved by virtually scaling the nano data t
o normal sized surfaces perceived through a Head Mounted Display (HMD). This stereoscopic visualization is real-time capable while providing different rendering techniques for 3D (volumetric) and 2D datasets. This combination of appealing real-time rendering in conjunction with a direct haptic feedback creates an immersive experience, which has the potential to improve efficiency while examining SPM data.
