Finger Tracking Chemistry
A chemistry feature for a student teaching app in VR
I brought molecule interaction to VR, allowing remote students to learn chemistry.
Movement interaction was pretty easy to implement via finger pinch values.
One problem that arose with finger tracking was enabling rotation for the molecules.
Smooth rotation was accomplished by using the molecule as the epicenter and calculating the difference in angles relative to angle the interaction was initiated at.
For budgeting sake it was enough to allow rotation with another hand, where the other can freely move the objects.
