Rapid prototyping was a central part of my master thesis. The effect of part concepts was judged through user experiments.
To prove that there is no splash back of disinfective alcohol, when spraying it into the hands, the processes was filmed with a high-speed-camera.
Cleen is a hand sanitizer for the modern hospital wishing to decrease the number of hospital acquired infections.
Cleen is activated by the means of an optical sensor, the disinfective alcohol is dispensed through a unique spraying mechanism spreading the liquid equally at both hands.
The visible placement of the sensor guides the user to place the hands correctly enabling a touch free interaction. The spray mechanism gives a pleasant application of the disinfective alcohol and decreases the waste of disinfective alcohol at the floor drastically.
The combination of the bottom plate and the vertical placed sensor clearly communicates where to place the hands for correct interaction.
