Stery-Hand Evaluates How Well You Wash Your Hands
The first prize winner at the European Innovact Campus Awards 2011 offers a method to verify cleanliness.
Students from the Budapest University of Technology and Economics have created an invention called the Stery-Hand. This system can accurately identify disinfected areas on your hands and evaluate the quality of your washing.
Encased in a darkened box, the system uses UV lighting and a digital camera to feed the image of the user's cleaned hands to a laptop for processing with specialized software. The picture shows where UV-reflective disinfectant has been used and the quality of the cleaning is shown by way of color intensity. Red means the hand hasn't been treated, blue is a sufficient level, and green shows a well-treated hand.
