Denou Coil via the iPhone. Through watching the video below, you will see the iPhone being used to view the real world. The application will then pick up Air Tags depending on where the iPhone camera is looking. A click on a tag will then reveal information.
Applications include examples like giving out discounts at a restaurant, displaying information about your immediate surroundings, maps and what have you. Maybe a load of oppai jumping at you when in Akiba?
Details are still a bit fuzzy bit will try to bring the inventors along to the next CGM Night to get more info. Must get round to watching Denou Coil too.
