## Don't Just Sell Presence; Engineer for Interaction Virtual and Augmented Reality will be sold on the "wow" factor of presence—the feeling of being in another place. But its long-term value and customer loyalty will come from interaction. > “Presence will draw users in, but it is the interactivity quotient of VR that will keep it going.” Lesson: It's not enough to create a beautiful, immersive world. You must give users meaningful ways to engage with it. Ask: What can my customers do here? How can they affect their environment? How can they interact with each other in this space? ## The Body is the New Interface The keyboard and mouse are becoming relics. The future of interaction involves the entire human body: hands, eyes, voice, and posture. **Lesson:** Innovate in the interface. Develop systems that respond to gestures, track a user's gaze to anticipate their needs, recognize voice commands, and even read emotional states. The most intuitive and seamless interface will win.
