White Finger

White finger, sometimes also termed dead finger, is one of the dangers of vibration based haptic immersion over an extended period of time. It derives its name from the colour the body part initially turns on the onset of this condition. It is caused by a loss of blood flow by prolonged exposure to vibration, the same as experienced with heavy machinery, and despite the name, it can occur on any part of the body.

If exposure continues past the tissue bleaching, possible side effects include that body part turning numb, an increased sensitivity to cold, and finally, necrosis ? where the tissue literally starts to die off.

This is a real problem when it comes to figuring out how to replicate natural-looking finger movements.
