Results show that the detection ratio reaches 90% by using a spectrum intensity ratio with unsupervised classification and indicates the SSVEP is enhanced by proposed feature extraction with second harmonic.
Abstract
Recent years, a Steady-State Visual Evoked Potential (SSVEP) is adopted as a basis for Brain Computer Interface (BCI)[1]. Various feature extractions and classification techniques are proposed to achieve BCI based on SSVEP. The feature extraction of SSVEP is developed in the frequency domain regardless of the limitation in hardware architecture, i.e. a low power and simple calculation. We introduce here the feature extraction using a spectrum intensity ratio. Results show that the detection ratio reaches 90% by using a spectrum intensity ratio with unsupervised classification. It also indicates the SSVEP is enhanced by proposed feature extraction with second harmonic.

Brain-computer interfaces for communication and control.

TL;DR: With adequate recognition and effective engagement of all issues, BCI systems could eventually provide an important new communication and control option for those with motor disabilities and might also give those without disabilities a supplementary control channel or a control channel useful in special circumstances.

Human EEG responses to 1-100 Hz flicker: resonance phenomena in visual cortex and their potential correlation to cognitive phenomena.

TL;DR: An experiment, where ten human subjects were presented flickering light at frequencies from 1 to 100 Hz in 1-Hz steps, and the event-related potentials exhibited steady-state oscillations at all frequencies up to at least 90 Hz, which could be a potential neural basis for gamma oscillations in binding experiments.
