Chapter 17 The use of time-to-contact information for the initiation of hand closure in natural prehension

摘要: Abstract In prehension, the opening and closing of hand need to be coordinated with transport that same hand. We provide evidence for hypothesis this coordination is based on use first-order time-to-contact information. This information acts affect relative stability a regime regime, leading smooth stable transition from one other, rather than simply triggering closure upon passing critical value. Whereas manipulations target width, size, distance led pattern data could not captured by number competing models reaching grasping, appropriately parameterized dynamic timing model we adopted study fitted quite well. chapter pursue two goals at time. build case in prehension. At time, as vehicle discussing various aspects concept time contact application dynamical-systems models.
