Gaming Using BCI

MOTIVATION
 BCI is a technology that allows many folks to
connect with technology which are unable to make
use of other technologies like animals, small
children, old people and disable people.
 This technology has its applications in many fields.
Like health,engineering,automobile, psychological,
education etc
 This technology is the future of mankind. 3

PROBLEM STATEMENT
To Design A Device using Brain Computer
Interface
A Device can be any Hardware or Software.
 From Operating a Wheel Chair Using BCI to
Handling a GUI game Using BCI. 4
To Design a Device Using Brain
Computer Interface

AIM AND OBJECTIVES OF THE PROJECT
Aim:
 To design a device using Brain Computer
Interface to do work effortlessly.
Objectives:
 To detect Brain Signals using EEG recorder.
 To design GUI to interact with BCI device.
 To move a device using gestures.

INTRODUCTION
 One of the application of brain-computer interface
(BCI) is for entertainment.
 BCI games have potential extensibility in
combination with virtual reality environment.
 BCI game system is combined with a wearable
gesture interface, which detects electromyography.
 Wearable Gesture Interface increase user‘s feeling
of presence and fun. 7
Gaming Using BCI

LITERATURE SURVEY
 Neurosky company has created a game “Judecca”
a first person shooter game that uses a player’s
concentration as a key part of the gameplay .
 It uses a player’s concentration to make enemies
visible enabling the player’s “Devils Eye”, in
which they then must eliminate the newly visible
threats.

:To Design a Device Using Brain
Computer Interface

 Another BCI game prototype that uses concentration as
its main game mechanic is the fNIR based LazyBrains.
 Functional near infrared spectroscopy, or fNIR, is a non-
invasive optical technique that measures neural activity
related hemodynamic response within the cortex.
 When the user approaches a closed sewer grate, they
must lift, it requires tremendous concentration levels.

How BCI Game System Works

Android application which receives row signals
from the simple EEG recorder via Bluetooth.
The application detects beta/alpha ratios from the
row signals.
Depending on the beta/alpha ratio, the application
generates one-byte commands.
The application sends the one-byte commands to a
server running on a PC via TCP/IP over Wi-Fi and
LAN. 15
Computer Interface

The server converts the one-byte commands to
keyboard commands to operate the game
application.
The beta/alpha ratio is degree of concentration.
When a user concentrates, the beta/alpha ratio
increases.
The wearable gesture interface worn on a user's
arm, communicates with the PC via Bluetooth.
16
Computer Interface

The sensor detects two types of gestures of a hand,
a gesture of waving or shaking a hand or a
gesture of opening the hand.
The operating commands generated by the
beta/alpha ratio and the types of hand gestures,
controls avatar’s action in the game.
An immersive head mounted display displays the
advance of the game in the first person perspective
of the avatar.
17
Computer Interface

The head mounted display detects head motion of
a user and the first person perspective changes
according to the head motion.

Computer Interface

 In the game application, the avatar stands facing away
from a monster and fights with the monster. The
monster has hit points.
 The avatar shoots a fireball or a light ball. The hit
points reduces when the avatar is exposed to the flame
several times.

 The avatar protects oneself from the flame by
spreading a barrier.
 When the beta/alpha ratio becomes greater than or
equal to 1.2, an aura appears around the avatar.
20
Computer Interface

When the beta/alpha ratio becomes equal to or less
than 1.0, the aura disappears after 3 seconds.
The avatar shoots a fireball forward when the
gesture of waving or shaking the hand is detected.
And spreads a barrier with a shape of magic circle
on the front when the gesture of opening the hand is
detected.

APPLICATIONS
Gaming become enjoyable using Brain
Computer Interface.
Its gives experience of Virtual Reality to the
users.
It checks or challenges the concentration
levels of users mind. 22

CONCLUSIONS
 In this study, we proposed a hands-on game
by combining the BCI game system, which
were composed of a simple EEG recorder, a
smart tablet, a PC, and an immersive head
mounted display, additionally with a wearable
gesture interface, which detects
electromyography.
