Mug have two areas. First area is the area A with a single wall. We put finger on it when we are pouring a hot liquid. The warmth of the wall is changing and we can fell the level of hot liquid under the finger. Second area is the area B with double wall for holding.
Each items of my coffee set have 2 areas. Blue area has slippery glaze outside. Second area has white, mat glaze which is more functional for blind people. Grooves are informing us where is the end of the area A and beginning of the area B.
Blue and yellow are in contrast - which helped visually impaired people in perceiving differences between objects and shapes of items.
UCHWYTNE is my Bachelor's project.
