Is it pointing to grasping or grasping pointing?
The Smeets and Brenner view on grasping is simple: grasping is in fact pointing. In our comments we examine the model beyond the reach-to-grasp task, namely, by grasping (without reaching) of moving objects and eating. The model fits the data of both tasks. Although generalization of a model to different tasks usually strengthens its acceptance, in the present case it reveals its shortcomings, ...
متن کاملPointing and grasping in unilateral visual neglect: effect of on-line visual feedback in grasping.
Three experiments are reported examining judgements of the centre of a stick in a patient with unilateral neglect after right hemisphere damage. Replicating previous data [35, 37], judgements showed more evidence of neglect when pointing rather than when a grasp response was used (Experiment 1), particularly when pointing preceded grasp (Experiment 2). Neglect also increased for longer sticks a...
متن کاملFunctional anatomy of pointing and grasping in humans.
The functional anatomy of reaching and grasping simple objects was determined in nine healthy subjects with positron emission tomography imaging of regional cerebral blood flow (rCBF). In a prehension (grasping) task, subjects reached and grasped illuminated cylindrical objects with their right hand. In a pointing task, subjects reached and pointed over the same targets. In a control condition ...
متن کاملHandedness for grasping objects and declarative pointing: a longitudinal study.
It is still unclear whether infants become right-handed because of their left-hemisphere specialization for language (through gestural communication for instance), whether they speak predominantly with their left hemisphere because of this hemisphere's superiority in controlling sequential actions which first results in right-handedness, or whether the two lateralization processes develop indep...
متن کاملBiomechanics of Front and Back-of-Tablet Pointing with Grasping Hands
Considering the kinematic model of the hand allows for deeper understanding of target selection on the front and on the back of tablets. We found that the position where the thumb and fingers are naturally hovering when the device is held results in shortest target selection times. We broaden our understanding of that ergonomic optimum by analyzing the touch data as well as 3D data. That allows...
