Catch: HIV Detector is a pocket-sized device that encourages people in developing countries, who have limited access to healthcare, to test themselves for HIV at home.

By allowing users to test for HIV before it develops into AIDS, this device could save millions of lives each year.

"Catch is very simple in its nature," said the judges on this year's design master jury, which consisted of Dror Benshetrit, Margriet Vollenberg, Sindiso Khumalo, Rosanne Somerson and Talenia Phua Gajardo.

"It is extremely intuitive, can be used by anyone and can be used by anyone," they added. "It's designed to do all the thinking for the user."

Catch was selected out of the 12 winning projects in the design categories. "It's cheap, easy to mass-produce and a powerful took in tackling HIV and AIDS in countries with limited access to healthcare," said Vollenberg.
