  11. New Experiences And Opportunities!

  12. Controller Free Gaming – Happy Action Theater

  13. Casual Kinect - Agenda • Controller Free Gaming • Design Considerations • The Rules of Kinect • Things We’ve Learned • Q&A

  14. Design Considerations • What do you NEED? • Full Kinect support? My focus for today! • Seated skeletal tracking? • Hybrid support? • Forza 4 • Speech only? • Mass Effect 3

  15. Before You Start Kinect design • Embrace Kinect! • Controller mapping may not be… optimal. Testing • Be ready to prototype and test • Test early, test often • Good intentions are not enough! • When testing, sit aside and observe the player • You need to explain how to play? Need more work • Adjust the gameplay? Add feedback?

  16. The Challenge • Can we make virtual interfaces that • Are obvious how to operate • Communicate what’s happening • Are fast, comfortable and fun for your audience to use • And that, actually, you know, work?

  17. Casual Kinect - Agenda • Controller Free Gaming • Design Considerations • The Rules of Kinect • Things We Learned • Q&A

  18. THE RULES Of KINECT Explainwhat the player can do. Represent what they are doing. Make it fun to match the two. Testyour implementation.

  19. THE RULES Of KINECT Explainwhat the player can do. Represent what they are doing. Make it fun to match the two. Test your implementation.

  20. Explain What The Player Can Do • At every moment in the game, explain to the player • what interaction options they have • the effect of each option • Choose a clear conceptual model • Does the player immediately understand how to use it? • I know how to drive a car… • … but I don’t know how to fly a dragon

  21. Explain: What Gestures Are Being Detected? • Make it as clear as you can • Especially in games with non-obvious gestures • Easier if you’re just copying the guy onscreen • More than 3-4 available gestures? You have a challenge. • How do you teach a wider range of moves? • Show animations during loading? In game? • Tutorial at start? Ongoing? On main menu? Optional or not? • Reference guide on pause menu? • Can you redesign gestures to not need tutoring?

  22. Explain: Where Should The Player Be? • Tell the player where to position themselves • Playspace indicator at the start • Bring it up again if they drift • One or two players? • Intent to play

  23. Explain: Are There Voice Controls? • Does player know that voice is an option? • Show a microphone option? • When is the game listening? • Can the player open the mic selectively? • Say a trigger phrase, like “Xbox...”? • What phrases can the player say? • Aim for <10-15 in any one context • Can have many contexts

  24. Speech Recognition Case Study: VUI Bar • Engagement model • Mic indicator for speech-enabled menus • Keyword to engage • Teaching user the grammar • “See it, say it”  “Know it, say it” • Feedback and confirmation

  25. A New Way To Explain, In Your Menus pas·si·vate (ps-vt) v.pas·si·vat·ed, pas·si·vat·ing, pas·si·vates v.tr. To perform an instantaneous action on a UI element, that has an instantaneous effect that is non-critical, instantly reversible, but useful – perhaps showing more detail about the effect of that element; as opposed to an action that has a major effect (c.f. activate) passi·vation n.

  26. Passivation About this mode: Story Experience the single-player story You and a friend will repel the invasion together Play exciting minigames You and a friend will repel the invasion together Co-op Challenge Go

  27. Passivation Pistol Select Secondary Equipment Medkit Select Primary Weapon Grenades Rifle Shotgun Go Minigun

  28. THE RULES Of KINECT Explain what the player can do. Represent what they are doing. Make it fun to match the two. Test your implementation.

  29. Represent: The Player’s Movements • “Avateering” • Video image • Augmented Reality • 3D depth image • Menu pointer • ‘Image’ of your hands • Indirect (vehicle etc) • Limb highlights • Etc., etc., etc.

  30. How To Immediately Fail Your Kinect UI Review WAVE TO START! WAVE TO START! Curling 2011 MANAGER

  31. Represent: Drifting Out Of The Playspace Pause the Game “MOVE BACK!” and show triangle Pause the Game “MOVE LEFT/RIGHT!” and show triangle “MOVE FORWARD!” & triangle Pause the Game

  32. THE RULES Of KINECT Explain what the player can do. Represent what they are doing. Make it fun to match the two. Test your implementation.

  33. Make It Fun: Not Just Functional • Fun is the goal of every part of your game • Avoid frustration, delay and fatigue • Think about the physical and time costs of your UI design • If “taking inspiration”, understand and improve it

  34. Get To The Game! • Get to the game quickly • Avoid unnecessary menus • Skippable videos • Optional tutorial

  35. The Fastest UI Of All? • EFIGS + regional dialects + Japanese • Big hit on the dash • Very fast, very cool • Really easy to build • Passivation? • Not all languages • Needs backup?

  36. THE RULES Of KINECT Explain what the player can do. Represent what they are doing. Make it fun to match the two. Testyour implementation.

  37. User Testing • Good intentions are not enough • Your UI will have problems • Your biggest problems will be easy to find • Watching others use your UI will make you a better designer • Your users are not like you

  38. User Testing • To really test your UI… • … have someone try your game… • … then sit down and don’t talk! • Need to explain what to do? • Can the player figure out how to navigate? • Something’s missing! Need more feedback… • Odds are the player is right. You may be wrong!

  39. Remember When demoing your game, • You won’t be in their house to demo • Let the new player take control • Take notes and videos • Identify confusion and frustration • Identify what works, too!

  40. THE RULES Of KINECT Explainwhat the player can do. Represent what they are doing. Make it fun to match the two. Testyour implementation.

  41. Casual Kinect - Agenda • Controller Free Gaming • Design Considerations • The Rules of Kinect • Things We’ve Learned • Q&A

  42. Things We’ve Learned

  43. Making Aim And Hover More Fun • Avoid small and/or closely-spaced buttons • If you can’t, be very clear what’s selected • Bigger buttons better, but only to a point • Consider magnetic or sticky buttons • Repeated Accidental Activation Syndrome • Make the hover countdown clear • Make it proportional to the “cost” of the button • Costly to recover from bad selection? Make it longer. • Otherwise feel free to make it shorter, 0.75s can work! • Think how passivation can help you

  44. Like Totally Do These... • Live by The Rules of KINECT • Explainwhat they shoulddo • Represent what they aredoing • Make it fun to match them up • Testyour implementation • Make cutscenes skippable • Speed them to the fun bit • Keep the player in the right place Do!

  45. But These, Not So Much Mimicking a controller (go hybrid?) No play without ‘intent to play’ Overloading menu screens Assuming shared lingo Assuming the player has played game X Forcing players to have their photo taken Confusing Avatar’s hand with cursor Boring the player with unnecessary tutorial
