BCI-Brain Computer Interface

Brain-Computer Interface

Types of BCIs

Invasive BCI Non-invasive BCI

Virus attacks may occur to brain causing ill effects

Requires extensive training

BCI techniques are costly

Slow speed

Challenges in BCI

An infrastructure where data storage and data processing happens outside of mobile devices in a cloud

Mobile devices have limited resources

Data storage and computation power is transferred from mobile to cloud

Mobile Cloud Computing

Mobile Cloud Computing Architecture

Cloud service cost

Mobile network cost

Availability

Security

Challenges in MCC

Computer that could be worn on the body

Especially useful for applications that require computational support while user is actively engaged with the physical environment

Wearable Computing

Smart Glass

Smart Watch

Smart Head-mount used by soldier

Forms of Wearable Computer

Equipment may be heavy

Expensive

Can cause irritation in heat

Security

Challenges in Wearable Computing

Combination of Brain-Computer interface, Wearable computers and

Mobile cloud computing results in the perfect system that help

us to recognize an individual’s mental state.

Combining all the concepts

The electroencephalograph (EEG) signals are electrical signals generated by neuronal activity in the brain

EEG signal ranges from 1 µV to 100 µV in a normal adult

Electroencephalography(EEG)

Classification of frequency bands

MindWave headset (NeuroSky, Inc., San Jose, CA) Data is sampled from the sensor at a rate of 128

Hz

Hardware used in the process

Google Galaxy Nexus smartphone with Android 4.2 OS, and

A Linux server equipped with a quad-core Intel i7 microprocessor.

Structure of the prototype

Output samples

Determining the current mental states of the soldiers fighting a war

Determining the mental states of the pilot

Sometimes useful in Lie detecting test

Constant health monitoring for patients
