In purely virtual experiments, students interact with simulations through clicking or touching some widgets on the screen that represent physical variables. Mixed-reality experiments replace these graphical widgets with multisensory inputs (such as light, warmth, or pressure) that are semantically integrated with virtual and physical elements. This technology could help students build stronger mental associations of perceived facts and visualized concepts. The following YouTube videos show some prototypes.
A charge sensor,
a LabQuest Mini interface,
an LCD display, a computer
Setup: The charge sensor is connected to Channel 1 of the LabQuest Mini interface. Its black lead is grounded. Its red lead is placed at the middle position of the upper side of the screen.
