Neurocam - The iPhone camera that reads brainwaves & records everything that's interesting

The engineers who developed this neurocam say that they used iPhone so that the computing, analysis and image capture can be done using a single device. The system is still a concept and there are lot of possibilities. The neurocam is a result of the neurowear project being developed at Keio University in Japan. Professor Mitsukura along with others are working on this project.
Professor Mitsukura and team expects that in the near future, they'll be able to create an emotional interface to link to a wider range of devices and link services to people's thoughts and feelings. Since the device is hands-free, it's capable of capturing a life log of the things you found interesting.
With wearable computing rapidly trying to be mainstream and gadgets like Google Glass finding lot of popularity, it won't be long before the device will quickly tell the shop-owners what things you like and allow them to offer discounts. There are several interesting ways this system can be used. We'd like to ask our readers all the interesting applications they can think using this system.
We've a video that shows the system in action. Check it out -
