You are right, taking a limited project scope is a virtue: We merely want to make a proof of concept that inspires users with a mind-opening sense that the world's data can have higher dimensionality than just 2 dimensions. I (Jon) read the novel Flatland when I was a kid, and have ever since been yearning to see in more than just 2 dimensions. This project is an attempt to open users eyes in the same way. -- With the goal defined as proving a concept, it becomes apparent that we do not need to permanently solve every challenge with AR in a scalable way. We merely need to kludge around them (for example using tons of computing power) enough to make a convincing temporary experience: 1. Patterns of marks or lights can be placed on the outside of the headset, detectable by cameras in the environment. 2. True. Luckily we can achieve a kludgy demo by having one entire rendering computer (with graphics card) per depth slice, and selecting between their outputs as a dumb switch, post-rendering. 3. The plenoptic camera from lytro.com should provide the necessary post-capture-focusable images. We are meeting with Prof. Marc Levoy today to ask about partnering. -- We merely hope that once the concept of voxel vision has been proven, that all future AR systems will feature it as a standard mode of interaction.
