Easy: Neuracle’s SSVEP-BCI uses steady state visual evoked potentials (SSVEP) to achieve brain-computer interaction (BCI). SSVEPs are generated by flashing stimuli in different sections of the screen. The SSVEP-BCI systems constructed are based on frequency and phase modulation. The stimuli flash at different frequencies and their associated brain responses can be used as inputs to a computer. SSVEP-BCI has reached relatively high information transfer rates and requires little user training.
Fast: When the character spelling rate is 60 characters/min the system achieves higher recognition accuracy (over 90%) and faster recognition speed (1s). The average information transmission rate (ITR) of Neuracle’s SSVEP-BCI is 185.4bits/min, which is superior to other currently reported EEG-based BCI platforms.
Broad Applicability: SSVEP based BCI is useful in many different sectors. In the medical field, it will become an important bridge for patients to communicate and interact with the outside world. BCI can also be combined with VR, UAV, and robotics to contribute to lifelike gaming experiences for the entertainment sector. In the military, BCI can used for brain-controlled UAV detection, heavy weapon control, and silent communication between soldiers.
