With more and more phones featuring beefy processors, GPS, HSPA data, and compasses, augmented reality apps are ready to take off in a big way. Layar, in particular, is shaping up to be the platform of choice from which to overlay information onto the streets that surround you. This is great for serendipitous discovery of cafes, ATMs, real estate, and even jobs, but at what expense? Recently, we casually joked about the ability to "hunt down tweeps with cold, calculated precision." Now a Dutch crew from Beste Product took up the task by giving Layar and its "Famous People Finder" feature a real-world test on the streets of Amsterdam with the help of Samsung's i7500 Galaxy. The results are unsettling as demonstrated by the celebrities, including Brad Pitt's, reaction to being discovered. Is our near-term future to be filled with people laughing maniacally while pointing their cellphones at each other? The video is in Dutch, but the reaction that unfolds at 2 minutes and 40 seconds is universally human. See it after the break.
