Human haptic perception is interrupted by explorative stops of milliseconds

Introduction:

The explorative scanning movements of the hands have been compared to those of the eyes. The visual process is known to be composed of alternating phases of saccadic eye movements and fiation pauses.

Methods:

Five different Experiments were used. The first two Experiments were classical recognition tasks of unknown haptic stimuli (A) and of common objects (B).

Results:

In each Experiment we observed explorative stops of different average durations.

Conclusions:

We assume that ES are a general aspcect of human haptic exploration processes.
