Abstract Background It has been suggested that Brain-Computer Interfaces BCI may one day be suitable for controlling a neuroprosthesis. For closed-loop operation of BCI a tactile feedback channel that is compatible with neuroprosthetic applications is desired. Operation of an EEG-based BCI using only vibrotactile feedback a commonly used method to convey haptic senses of contact and pressure is demonstrated with a high level of accuracy. Methods A Mu-rhythm based BCI using a motor imagery paradigm was used to control the position of a virtual cursor. The cursor position was shown visually as well as transmitted haptically by modulating the intensity of a vibrotactile stimulus to the upper limb. A total of six subjects operated the BCI in a two-stage targeting task receiving only .
