My recent work for a industory-university cooperation project.
When you open a door with KNOB, it's a natural to handle it by your hands.
But how do you use the knob when both hands are full or get wet?
I designed the KNOB for KNEE.
You have to no longer take a common way.
Through the 'VIA' (I named it), you need only either of knees instead of your hands.
And also statistics showed the knob is one of the source of infection.
