After three years of research, planning and designing, we came up with the concept of “Hi Toilet” where all commands are activated by voice. My inspiration to design a fully voice activated toilet came after reading about users' behaviours in public toilets across Europe and the US to avoid contact with the surface; 60% stepping on toilet levers to flush, 50% opening the door with toilet paper, 40% closing the door with hip, 30% avoiding hand-contact as much as possible by using elbow.
