Shopping just got a little bit more exciting at Jumbo, MediaMarkt and Rádio Popular markets in the greater Lisbon and Porto area. YDreams and Krups-Nescafé Dolce Gusto came up with a unique concept for promoting the latter’s coffee machine and capsules at Point-of-Sale displays in central and northern Portugal.

Displays featuring built-in giant screens covered in multi-flavoured Nescafé Dolce Gusto coffee-capsules seemed to make even the caffeine averse curious. As people drew near the capsules drifted apart to uncover real-time video feeds of shoppers in the background. The YDreams app, dubbed YFaces, pinpointed their position and popped comic-strip style balloons up over their heads with fun, catchy phrases like “I dig this machine – I’ll take it!” or “I could go for a Latte Macchiato right about now”.

Not bad for an afternoon at the market – sampling free espressos and getting your mind read

Finally I found some info on this much discussed subject.

It was done by an UK company, Musion.

It’s basically about bouncing off the light from any projector or screen.

They say they have a patent on it, altough this technique has already been extensively used in the past.

I suppose their claims come mainly from the film properties.
