3. Brainstorming
• Environment should encourage imaginative
thoughts and ideas
• Discipline: no suppression, careful capturing
& further analysis
• Fun factor as a moving force of imagination*

5. Brainstorming
But how to:
• feel the encouraging environment?
• generate ideas without conflicts?
• have all ideas captured for the later review?
• have fun collaborating?

8. iPad
• 9.7’’ Multi-Touch display
• 0.68 - 0.73 kg weight
• 1.0 Hz CPU
• Connectivity (WiFI, 3G, BT)
• Sensors (Compass,
Location, Accelerometer)
• Familiar SDK
...looks as a great platform for prototyping
