Emergency Call using EEG and Android Operation System for Disabled People
Emergency
call using EEG and Android operationsystem for disabled people is a new kind of
science and technology, which includes the sciences and technologies of the
optical system of the eyes [1], Brain Computer Interface (BCI) [2], signal
processing, communication, and control. For disabled people to use phone call,
scientists created a system which was designed and implemented based on the
control of EEG signals in Nanchang University [3]. An online calling system and
spelling system is realized on a BCI experimental platform based on
steady-state visual evoked technology (SSVEP) to translate the EEG into control
command [4]. Commonly, there are two kinds of visual stimulator: LED visual
stimulator and LCD visual stimulator. The EEG signals feature extracting can
use power spectral density analysis or canonical correlation analysis (CCA).
CCA finds the max correlation coefficient between EEG and reference signal to
extract the frequency feature [5]. In this research, we develop an Emergency
calling system embed into the Pad Phone by using EEG and Android operation
system for Disabled People. The remainder of this paper is organized as
follows: section 2 deals with the overall design of embedded emergency calling
system based on BCI; section 3 focuses on the EEG acquisition and transmission;
section 4 deals with the emergency call software design; section 5 illustrates
the results of emergency call tests and the analysis; section 6 finally gives
the conclusions of this paper
