A Portable Brain-Computer Interface Using Micro-Display for Future Mobile Communication System

5G is gradually realizing low latency and high reliable transmission between devices. In the next-generation mobile communication system, in addition to the further evolution for conventional communication technology, a new way of human-machine communication (HMC) represented by brain-computer interfaces (BCIs) will appear to achieve more efficient human-machine communication. BCIs based on steadystate visual evoked potential (SSVEP) are becoming one of the most popular research direction because of its high accuracy and less dependency on data training. However, the implementation of SSVEP-BCIs depends on external visual stimuli which usually use computer monitor to display the external stimuli. Therefore, this kind of BCIs usually has poor portability and wearability. This disadvantage is hindering the combination of BCIs based on SSVEP and specific control scenarios such as aircraft control, which require high wearability of control devices. The current portable schemes usually make use of the binocular effect and AR glasses to improve portability but no BCI system has been designed by making full use of the conclusion that stimulating single eye can also stimulate the brain to produce strong responses. In order to improve the portability of the BCIs based on SSVEP, a monocular-based scheme is proposed in this study. A brain-controlled aircraft system based on SSVEP is designed to verify the feasibility of this wearable scheme.
