2. Use Case 2 - Background
Problem
• Exercising is no fun!
• People know they should exercise, but are not
motivated to do so

3. Use Case 2 - Background
Solution
Offer user an enriched environment
Offer user interactive help
Use multiple sensors to gather user data

4. Use Case 2 - Prototype
Prototype
• Setting: Living room
• Exercise equipment: Home trainer
• Enriched environment: Virtual World
• Interactive help: Virtual Exercise Coach
• Sensors: Both real and virtual

5. Use Case 2 - Equipment
Home trainer system
• i-Magic from Tacx
• Computer ready (USB)
• SDK available
• Adjustable friction
• Simulation of terrain (sand, asphalt, cobbles)
• Detection of steering

6. Use Case 2 - Equipment
Biosensors
• Gather physiological data
• Heart rate
• Blood pressure
• Gather mental state
• Stress

8. Use Case 2 – Virtual Coach
Virtual Exercise Coach (VEC)
• Centre of the system
• Gathers and processes real world and virtual world data
• Mimics human emotional behavior in response to the
user (video and audio feedback)
• Keeps track of the user’s previous and
current situations
• Offers additional information (tour guide)

9. Use Case 2 – Technological model

10. Use Case 2 – Mobile alternative
Easy to extend – Mobile version example
• VEC programmed for the iPhone
• Audio is primary feedback
• Activity monitor (Nike+)
• GPS and compass help to navigate and
can be used to record the session for replay
• Biosensors can be integrated

11. Use Case 2 - Questions
1. What virtual world allows:
• Absolute and relative positioning?
• Programming or inserting of a VEC?
• Enough responsiveness
2. What about IP?
• Who supervises the IP issues?
• How do you expect the
consortium to handle your
Top Secret ideas?
