DabKick VR is a new app for Vive I'm helping launch, so I'm massively biased when I say this, but I think it's a unique twist to "social VR", in which the virtual world space is accessible not only to people wearing headsets, but also people accessing the same app from their smartphones:
[W]e think social VR can’t succeed unless the vast majority of non-HMD owners can also participate in the experience. This is why we’ve created an immersive, virtual theater, where Vive users can enjoy both video and images together with DabKick app users connected via their iOS and Android phones — all represented as avatars in the same virtual space, together... Maximum concurrency per session: Technically up to 100,000, but feasibly, up to 200 avatars in the entire theaters watching together.
Lead developer Balaji Krishnan wrote a post explaining why this cross-platform approach may work where pure VR experiences may not:
I believe the way forward is thinking about social VR embedded in a larger social experience that transcends VR. Or to put it another way: Once one of your friends puts on a VR headset, what do the rest of you do? We’ve all seen YouTube videos of people at parties laughing their heads off while one friend in VR flails around, trying to hit unseen zombies. Enjoyable to be sure, but the novelty of one person in VR while everyone else watches soon wears off. This highlights the greater challenge: Creating social experiences for virtual reality when the vast majority of consumers still devote most of their online screentime to the devices in their hands or on their lap — not strapped to their face.
