The document discusses the integration of brain-computer interfaces (BCI), mobile cloud computing, and wearable computing to create a system that can assess mental states. It addresses challenges such as high costs, speed limitations, and security while highlighting the use of EEG signals and various wearable devices like smart glasses and head mounts. The technology is particularly relevant for applications in military settings, healthcare monitoring, and even lie detection.

 WC-Wearable Computing
 Combining all the three concepts
 EEG- Electroencephalography
 Hardware and Software used in the process
 Why mobile cloud computing?
 Structure and working of the prototype
 Challenges and solutions

4.  Brain-Computer Interface
Invasive BCI Non-invasive BCI

5.  Virus attacks may occur to brain causing ill
effects
 Requires extensive training
 BCI techniques are costly
 Slow speed

6.  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

8.  Cloud service cost
 Mobile network cost
 Availability
 Security

9.  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

10.  Smart Glass
 Smart Watch
 Smart Head-mount used
by soldier

11.  Equipment may be heavy
 Expensive
 Can cause irritation in heat
 Security

12. 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.

13.  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

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

16.  Google Galaxy Nexus smartphone with
Android 4.2 OS, and
 A Linux server equipped with a quad-core
Intel i7 microprocessor.

19.  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
