Control your mobile device without touching or speaking
Make control easier in environment require less movement or silence
library classroom
The narrow version for mobile device

Control many device in a more effortless way
Determent human emotion for many purpose
The generalized version

Electroencephalography Device that recording electrical activity of
brain
EEG

P300 is a pattern of certain electrical brain activity
It is usually happened when people try to reacting to certain thing
Typical representation is the record of EEG have a “delay” for 300 to 600 ms
P300

A way to generalize data, to figure out a pattern. So that we can use the pattern to determent or predict new situation

The application take very little resource Which means devices like smart phone
could totally hand the brain control system
An acceptable Accuracy
Shows

Algorithm is not perfect yet High battery consuming EEG hardware not good enough
Limitations

It is a concept prove application It proved that brain control on mobile
device can be done The compute unit is powerful enough
already The algorithm can be improve EEG still need improve
