1. Brakey
Unlock a safe ride

2. Introduction
Original Question:
Is there a way we can enhance UCSD
students' skateboarding experience with a
gesture based interface?

3. Initial Findings
● handling speed wobbles
● braking
● detecting and avoiding rough terrain
● a more compact longboard

4. Initial Ideas
● stabilizer
● infrared collision detection
● collapsible board
● mobile route network

5. Initial Ideas

6. Our Big Question
New Focus:
Can we design a gesture based brake for
the longboard that improves the riding
experience for UCSD students?

7. Current Solutions - Pogo Brake

8. Current Solutions - ZBoard

9. Current Solutions - Skate+Safe

10. Current Solutions - Public Patent

11. Initial Prototypes
● six prototype 'braking gestures'
● includes an activation & engagement step

12. Prototype Gesture Tests
● 6 trials per user

13. Prototype Gesture Tests
● Quantitative Data
○ 1-7 - Natural, Easy, Balanced, Comfortable
● Qualitative Data
○ Is this better than the normal way?
○ When would you use it?
○ Foresee problems?
○ Unintentional activation?

16. Trial 3
● Rotate to activate, side pedal to brake
● Feedback:
○ Similar to natural braking method
○ Scary to use at high speeds
○ Possibly hard to balance

17. Trial 4
● Weight forward to activate, rotate to brake
● Feedback:
○ More fluid motion
○ Fear of false activation

18. Second-Round Prototype

19. Analysis - Our Approach
● T-shaped approach
○ started broad
○ honed in on speed regulation

20. Analysis - Problems
● Issues we dealt with
○ paper prototypes
○ variations in:
■ boards, participants, styles, etc.
○ limitations:
■ hard to set standards
■ difficult to find beginners

21. Analysis - Redo?
● If we could do it all over again....
○ Choose a standard board type
○ Focus on more specific target audience
○ More realistic user tests

22. Conclusion
● Not your average interface
● You never know until you ask
● People can learn
● Design is absolutely a process

23. Next Iteration Prototype
● Brake with feedback
○ visual
○ tactile
● Make brake more self explanatory
● Testing on beginners
