I believe this could be a very sophisticated framework to build next generation learning content. At present we are mostly waiting for head-mount display technology to mature. When we have a full color sunlight-readable overlay display with an apparent resolution of about 90dpi at 2feet (say, 180 arc-seconds) this will really take off.

The car is just an example but think how far the e-learning industry can go with this technology. There are already some prototypes with children book and story telling out there in the market. I think we need companies to invest in custom content development projects in this platform. I believe this will change the way we perceive online learning.
