Discrimination thresholds for haptic perception of volume, surface area, and weight
The present study investigated the human ability to discriminate the size of 3-D objects by touch. Experiment 1 measured the just noticeable differences (JNDs) for three tasks: (1) discrimination of volume without availability of weight information, (2) discrimination of volume with weight information available, and (3) discrimination of surface area. Stimuli consisted of spheres, cubes, and te...
متن کاملAppropriate Lengths Between Phalanges of Multijointed Fingers for Stable Grasping
n appropriate arrangement of finger joints is very important since the stability of grasping an obj :atly depends on that arrangement. Multijointed fingers can grasp an object with many points of conl :h of which is pressed against the object as if wrapping up that object. The amount of the wrapped up a d the form of the finger when an object is grasped are therefore important factors for deter...
متن کاملDetection for Haptic Exploration with Robotic Fingers
The authors consider the detection of small surface features, such as cracks, bumps, and ridges, on the surface of an object during haptic exploration and dexterous manipulation. Surface feature definition and detection are essential for intelligent haptic exploration and modeling of unknown objects. First, the authors review the representation of object surface geometry and present definitions...
متن کاملHaptic subitizing across the fingers
Numerosity judgments of small sets of items (≤ 3) are generally fast and error free, while response times and error rates increase rapidly for larger numbers of items. We investigated an efficient process used for judging small numbers of items (known as subitizing) in active touch. We hypothesized that this efficient process for numerosity judgment might be related to stimulus properties that ...
متن کاملTesting for haptic perception.
I n this edition of Arquivos de Neuropsiquiatria Nascimento et al. 1 present the results of a group effort in the development of a scale to measure haptic perception. Haptic perception is the " extraction of information about an object's properties such as its size, shape, and texture by means of exploratory manual movements " 2. Although haptic perception is largely dependent on touch, it is i...
