Before making the movie Minority Report, Steven Spielberg gathered a group of futurists together to brainstorm on what life would be like in 2054. One of their key predictions? The startling rise of personalized interactive advertising.
While nobody may be scanning your retinas quite yet, interactive billboard advertising has taken great leaps in recent years. Japanese company NEC is working on facial recognition software that can pick individuals out of a crowd and guide messaging toward them.
Current types of interactive advertising are more fun and participatory in nature, and come with fewer privacy issues. For instance, billboards that let you control something on the board via a smartphone. Or ads that sense you walking by and try to attract your attention via audio and video cues.
The only limit seems to be whatever the limits of current technology. And that's changing by the minute, so stay tuned.
