Brain-computer interfacing under distraction: an evaluation study.

abstract：OBJECTIVE:Haptic feedback is crucial when we manipulate objects. Information pertaining to an object's stiffness in particular can help facilitate fine motor control. In this study, we seek to determine whether objects of different stiffness levels can be recognized using haptic feedback provided by transcutaneous elec...
