Road users might be familiar with the “speed smiley”. If you are driving too fast, the smiley is angry. If your car is below the speed limit, the smiley is happy.
This principle can be adapted to the motivation of health care workers for hand disinfection. The study of Gaube et al. emphasizes this “How a smiley protects health: A pilot intervention to improve hand hygiene in hospitals by activating injunctive norms through emoticons”
There will be a display above the dispenser. Both communicate via bluetooth with each other. It is up to the person that is in front of the dispenser if the smiley is happy or angry. The motto of the smiley is: “Push my until I am happy!”
The awareness for hand hygiene has to be continuously sensitized. A display above the dispenser can be helpful for that. Depending on the behavior of the person passing by the smiley changes its emotional state.
Missing dispenser activation: angry smiley
The display has an integrated sensor that detects if someone is in the field of view. The longer the stay within that view without hand disinfection the angrier the smiley gets.
Done dispenser activation: happy smiley
NosoEx monitors every dispenser push and the associated dispensed amount per hand disinfection. If the person pushes the dispenser more often to reach the dispensed amount of 3 ml (recommended by WHO) the more happy the smiley is on the display.
