SCENARIO

5. SCENARIO
• The players get dressed and select a weapon.
• Armor, helm and shield.
• Discovery.
• They get into the labyrinth and then they start to
look for other players.
• A fight will start once they find one or more
players.
• They will get activated if a player is low on life.

• Healing points.

6. DISCOVERY
• The player puts the smartphone inside the armor.
• A NFC tag will trigger the discovery.
• The smartphone connects to:
• The wearable sensor network [Bluetooth].
• The audio wireless system [Bluetooth].
• The game network [Wi-Fi].

• Everything takes place while the player is getting
dressed.

7. SMART DEVICES
• Smartphones.
• Around a 73% of the inhabitants will have one in
the next years.
• Zero cost.
• It can hold the computational load of our system.
• No need of a central server.
• Text-To-Speech
• Wireless audio system.

• Piezoelectric triggers.
• Embedded in the wearable parts.
• Heart rate sensor.

9. SMART ENVIRONMENT
• Triangulation.
• Using the mesh of routers.
• Virtual positioning.
• Special events.

• Ambushes.
• Healing points.
• Activation of IP light bulbs.

10. SMART INTERACTIONS
• Healing event.
• It will start if a player is low on life.
• A light will be turned on to mark the healing point.
• The player must be in <3m around the point for 3’.
• Triangulation.
• It increases the damage dealt to the ambushed
player.
• It takes place when a player gets close to an enemy
from a distance>10m in few seconds and deals a hit.

ACTIVITY DESIGNER SCHEME

13. PROPERTIES
• Our scenario is completely delimited and covered by
our system.
• It takes into account the position, the identity, the
activity and the time to adapt the system.
• The system changes in order to adapt
environment to the player before they need it.
the
• The players will not notice any of the devices part of
the system.

• It changes many parameters taking into account the
user or the environments requirements.

14. EXPECTED PROBLEMS
• Recognition of false hits.
• When more than 2 players in the same point deal a
hit at the same time.
• False start of events.
• When two players can start an ambush event.
• In advance stages of the system, a single player will
be able to select a weapon from an arsenal.

• Connection weapon-Player ID.

15. CONCLUSIONS
• Our system can be implemented.
• Low cost.
• High scalability.
• Interesting for a wide range public.
• Any age.
• Any likes.

• Completely transparent and ubiquitous.

16. Thanks for your attention
Take a weapon and
enjoy the fight!
