Well, not you specifically, but rather certain defining characteristics, like your age and gender.

NYC startup Immersive Labs has created billboards and in-store displays that use facial-recognition software to determine the age and gender of viewers. Why? For targeting of course – these displays can then change the ad being shown based on viewers’ characteristics. The displays can also customize ads based on the local data like the weather, and can monitor viewers’ attention, distance from the display, and number of “glances.” As HuffPost Tech reports, “Targeted advertising is the golden goose of the online economy: ads keyed to a user’s unique interests have been shown to double the effectiveness of traditional ads. But those ads have been restricted to the Internet – until now.”
