This document proposes a concept for a pervasive laser tag game called "Future Warfare" where players use laser guns, sensor-equipped jackets, and a smartphone app to track each other on a map and shoot each other, with the app handling player registration and match creation, providing real-time player locations and status updates, and communicating with the laser guns and jackets via Bluetooth. The laser guns and jackets would be built with Arduino/Genuino components like lasers, sensors, and Bluetooth modules to detect hits and track ammunition, while the app manages the game's rules, interface, and online match database.

2. The Game
• Future Warfare is a laser game concept
• Each player, more than one, have a laser gun
• The goal of the game is to kill others enemies
• When munitions end, the player must refill it in regards place in the map

3. Requirements
Players have:
• One laser gun
• A war jacket in which there’s sensor
• A smartphone

4. Laser Gun
• Laser game’s idea
• Gun is devoloped with
Genuino
• It is able to shot against
enemies’ jacket
• Gun has limited bullets
• A smartphone is supported
by the gun

5. War Jacket
• War jacket contains Genuino and its
sensors
• Genuino interacts with application in the
smartphone
• One of the sensors is laser bullet receiver
• When a player shoots to the laser receiver,
the LED sensor lights on

6. Requirements
• Arduino/Genuino uno
• Laser
• IR Receiver
• Piezo
• Bluetooth (HC-06)
• Basic electronics components
• Fritzing
ARDUINO:

7. Implementation
Laser
• Simple commercial Laser
• It’s the sender for IR Receiver
• When trigger is hit, laser beam is emitted by Laser

8. Implementation
IR Receiver
•TSOP38238
•First pin to Arduino pin
•Second pin grounded
•Third pin to 5V by 220 kohm resistor

9. Implementation
Piezo
• Supplementary object
• It is not mandatory for the whole project
• Used to manage some particular sound aspect in particular moment of the game

10. Implementation
Bluetooth HC-06
• Used to connect with Android Application
• It sends current munitions and dead/alive notification when required by user with
android implementation (more in details later)

11. Fritzing
Fritzing
•It’s an “open-source hardware initiative that makes electronics accesible as a
creative material for anyone”
•It provides us tool in order to create electronic circuit following

14. • Application have all the requirements the player need to play.
• It shows the map where the game takes place
• When a player shoots, his position will appear in the enemies’ map for few second
• It shows remained bullets, the time game, enemies and the score.
• Other features will be implemented during the project
Smartphone App

15. Requirements
Android Application:
• Frontend: Android Mobile Application
with internet connection, GPS and
Bluetooth turned on [paired with HC-
06 module]
• Backend: php methods hosted on a
web Database (Altervista.org) to store
informations of the app
• Android Studio
• Several Google API to interacte with
Google Maps

16. Login / Register Activity
• The application start with Login Menu
• Registration is mandatory for the game
• Data are stored in external Web Database called
“ModernWarfare” on Altervista.org

17. Login / Register Activity
• The application start with Login Menu
• Registration is mandatory for the game
• Data are stored in external Web Database called
“ModernWarfare” on Altervista.org

18. Home Page
• This activity contains three buttons:
• Connect Here: it sends the user to bluetooth
connection functionality in order to connect with it.
If connection is established, Create game and Join
game are enabled.
• Create Game: it allows the user to create new
game
• Join Game: it allows you to join to an existing
game.

19. Bluetooth Activity
• This activity contains a list of paired devices:
• Touching one, you’ll connect to.
• An alert message will appear due to connection
established.

20. Create Game / Join Game
• In create game activity, we fill mandatory dates for
the game.
• Game name is univocal: an existing name
instertion won’t start the game.
• In order to push the game inside DB, a php
method is called since you complete this forms
near.
• Join game activity, instead, contains the list of all
created but not beginning match.
• When game started, the game match inside DB is
deleted in order to prevent a user could join to a
started game.

22. Waiting Activity
• This activity differs according to user rule.
• Game creator functionality:
Start Game
Delete Game
• Player functionality:
Unsubscribe
• A thread works parallels to steadily update current
players number [showed to creator]
• Another thread [for player] is waiting for the
beginning of the match and, when match starts, it
changes activity.

23. Waiting Activity
• This activity differs according to user rule.

• Player functionality:
Unsubscribe
• A thread works parallels to steadily update current
players number [showed to creator]
• Another thread [for player] is waiting for the
beginning of the match and, when match starts, it
changes activity.

24. Main Activity
• It contains a map offered by Google Maps
• Every fifteen seconds, player’s “makers” will appear in the map for six seconds.
• Thanks to “i” button, it’s possible to see game information
• A countdown shows remaining match time
• A related thread works with Arduino via bluetooth requiring remained munitions and number of
dead time player’s.

25. “To-Do” list
• Possibility to choose between two game mode: friendly match and
deathmatch
• The current one is a friendly match [time based].
• The new one will be a deathmatch game:
- each person has three game lives
- the last one alive wins
• Assembly of Arduino components with the Jacket and the Gun

26. Thanks for your attention!
Any suggestions?
