WATCH | Smart dresses show just how often women are groped

Researchers built a dress embedded with sensors to track how often women in Brazil were groped on an average night out.

Quartzy reports that researchers sent three women to a party wearing the dresses. Throughout the night, we see a heat-map version of it steadily light up in the areas where the women are being grabbed: mostly the lower back, backside, and arms. The visual is imposed over footage of the women brushing off the men and asking not to be touched.

In just under four hours, the women are touched a combined 157 times.

Advertising agency Ogilvy had the dresses created for a campaign on behalf of beverage company Schweppes.
