3. Introduction
 Control is one of complex engineering tasks that need
compatibility between two different systems.
 Our project is a controlled computer, especially racing
games through the mobile devices
 This is done by measuring the exact movement of the
mobile in any direction north or the right to be applied
to a racing game

4. Introduction…
 Values ​are taken resulting from the movement of
mobile and filtered and then sent via Bluetooth to a
computer.
 Values ​usually range between three types
Movement to the right in specific value
Movement of the North in specific value
Stop Motion
 After that, these movements are sent to the racing
game installed on your computer

5. Android OS
 Android is a Linux-based operating system designed
primarily for touchscreen mobile devices such as
smartphones and tablet computers.
 Android become the world's most widely used
smartphone platform, overtaking Symbian in the
fourth quarter of 2010.

6. Android OS…
Why Android ?
 open source code and permissive licensing allows
the software to be freely modified and distributed
by device manufacturers.
 Android has a large community of developers
writing applications.
 In October 2012, there were approximately 700,000
apps available for Android

7. Android Sensors
 Android Mobile has 13 sensor divides as software
or hardware each sensor has specific task.
 We will talk about just 2 sensors which we use in
our project.

8. Android Sensors…
 Linear accelerometer sensor
Type :
Hardware
Description :
Measures the acceleration force in m/s2 that is applied to
a device on all three physical axes (x, y, and z), excluding
the force of gravity.

9. Android Sensors…
 Gravity Sensor
Type :
Software or Hardware
Description :
Measures the force of gravity in m/s2 that is applied to a
device on all three physical axes (x, y, z).

10. Android Sensors…
 By moving your mobile linear accelerometer sensor
and gravity sensor give to us 3 values every value in
different axis ( X , Y , Z ).
 Software installed on android Mobile use these values
to detect 3 instruction depending on your movement
previously mentioned :
Move the object Left
Move the object right
Stop moving

12. Connecting
The project consists of two programs
 The first program: is on his Android mobile his job is
to create Bluetooth communication with PC.
 The second program: exists on the device and receive
connection request accept in and start receiving data.
 We use Bluetooth connection

13. Controlling
 First : Android send the instruction to PC.
 Second : PC receive these instruction and apply them
to running game .
 In flash games apply theses instruction simply using
keyboard events
 In complex game (Need For Speed ) you should access
DirectX package to give movement instruction.

14. Problems
In this project we had faced many problems
 1- It is very difficult to get a very accurate value
based on the X , Y , Z values ​and then determine
the direction.
 2-most of complex games make low level
instructions using assembly language and to
control motion .

15. Conclusion
 We can extend our project to control PC windows not
just Games.
 We can use internet connection instead of Bluetooth
connection.
 I hope that you are interesting with this presentation.

16.  I remove the video due to Model limitation in size
