Recently, a new modality of the human-computer interface has been more and more emerging; The Brain-Computer Interface (BCI). The BCI is a communication channel, which enables us to send commands to external devices by using human brain activities (Wolpaw et al., 2002). As one of the remarkable achievements, we can see the report on invasive Brain-Machine Interface (BMI) (Hochberg et al., 2006)...

introduction: in most bci articles which aim to separate movement imaginations, µ and β frequency bands have been used. in this paper, the effect of presence and absence of γ band on performance improvement is discussed since movement imaginations affect γ frequency band as well. methods: in this study we used data set 2a from bci competition iv. in this data set, 9 healthy subjects have perfor...

EEG-based brain computer interface (BCI) provides a new communication channel between the human brain and a computer. The classification of EEG data is an important task in EEG-based BCI. In this paper we present a new modification on classic "Peak Picking" to make a better detection for a specific pattern in EEG. The new method shows a significant improvement in P300 detection which is a commo...

This paper presented the technique of robot control by event-related potentials (ERPs) of brain waves. Based on the proposed technique, severe physical disabilities can free browse outside world. A specific component of ERPs, N2P3, was found and used to control the movement of robot and the view of camera on the designed brain-computer interface (BCI). Users only required watching the stimuli o...

Brain-Computer Interface (BCI) uses brain’s neural activity to interact with others or to control machines, prosthetic limbs, or robots without any direct physical movements. Electroencephalography (EEG) measures the electrical signals generated by the neurons in the brain, by placing electrodes along the scalp. BCI helps disabled individuals by providing a new channel of communication with the...

The Brain Computer Interface (BCI) has a great impact on mankind. Many researchers have been trying to employ different classifiers figure out the human brain's thoughts accurately. In order overcome poor performance of single classifier, some used combined classifier. Others delete redundant information in channels before applying classifier as they thought it might reduce accuracy BCI helps c...

Multi-modal techniques have received increasing interest in the neuroscientific and brain computer interface (BCI) communities in recent times. Two aspects of multi-modal imaging for BCI will be reviewed. First, the use of recordings of multiple subjects to help find subject-independent BCI classifiers is considered. Then, multi-modal neuroimaging methods involving combined electroencephalogram...

Electroencephalograph (EEG) has been widely applied for brain-computer interface (BCI) which enables paralyzed people to directly communicate with and control external devices, due its portability, high temporal resolution, ease of use low cost. Of various EEG paradigms, steady-state visual evoked potential (SSVEP)-based BCI system uses multiple stimuli (such as LEDs or boxes on a computer scre...

To date, the application of brain computer interface (BCI) technology in rehabilitation represents one of the most challenging matters in the BCI filed. With the aim of developing a specific BCI system for speech language rehabilitation, this paper describes framework of a novel BCI system designed for clinical settings in speech language rehabilitation. It presents an overview of the technolog...

Games that use brainwaves via brain-computer interface (BCI) devices, to improve brain functions are known as BCI serious games. Due to the difficulty of developing BCI serious games, various BCI engines and authoring tools are required, and these reduce the development time and cost. However, it is desirable to reduce the amount of technical knowledge of brain functions and BCI devices needed ...
