KidsRoom

Disney’s Aladdin

3. Design Criteria

A beginner user should:

Locate the right on-screen keys at their second visit

Bypass 75% of the obstacles at their second visit

Make less then 3 gesture errors

Succeed in completing the adventure at their second visit

4. Storyboard

Initial Design Decisions

Feedback Crouching gesture Buttons location Repeat the tutorial

5. Prototype
