Last month, Jeremie Francone and Laurence Nigay who work in the Engineering Human-Computer Interaction (EHCI) research group of Laboratory of Informatics of Grenoble had figured out a way to use iPad 2’s and iPhone 4’s front facing camera for glasses-free 3D experience, which had generated a lot of buzz.
The good news is that, Francone and Nigay have recently released the app called i3D in the App Store for iPhone 4, iPad 2 and iPod Touch 4G.
Here’s the description of the app from the App Store:
i3D is an overview of Head-Coupled Perspective (HCP) on iOS devices. HCP uses the front camera of the device to track the face of the user in real time. This information tells the app how the user is looking at the display. The app updates the perspective of the 3D scene accordingly, giving the user the illusion that he looks at a small window.
i3D contains several 3D scenes that you can observe with HCP. It only relies on face tracking. It does not use the accelerometers or the gyroscopes.
You can checkout the impressive demo videos below from our previous post:
The app only works on iPhone 4, iPad 2 and iPod Touch 4G (each equipped with front facing camera) as it uses the front facing camera to track the exact location of the user’s head and render view dependent images on the screen to create a realistic illusion of depth and space.
You can download i3D from the App Store for free using this iTunes link.
They’ve provided the following tips in case you don’t get the glasses-free 3D experience:
- Avoid directional lights
- Do not use with backlighting
- Do not use in darkness
- Stay in the shot
It doesn’t work as smoothly as seen in the video but it’s a sneak peak of glasses-free 3D experience. We hope that Apple brings 3D tech to the next generation iOS devices.
Thanks Jack for the tip!
