A Case-Based Study of Students' Visuohaptic Experiences of Electric Fields around Molecules: Shaping the Development of Virtual Nanoscience Learning Environments
Figure 1
A panel of four screenshots from the virtual system displaying an H2O molecule with a van der Waals surface (a), an H2O molecule with visual field lines (b), and a corresponding CO2 molecule displayed in the same modes (c) and (d), all in a “ball-and-stick” representation. While interacting with the system, the viewer receives a 3D stereoscopic view of the molecules and can also rotate them. The stylus that represents the handle of the haptic device is also shown with the probe (small white sphere).
