Prof. Ying Fangtian, Chai Chunlei, Chen Qingyuan, Li Ke, Pan Yu, Cao Yu, Gu Shirong, Liu Yi, Pan Xiaobi and Li Xiaowei came up with a noble design that could help visually-impaired people also tell you what the time is. This is the +-8 Wrist Watch which has the ability to make you read, touch and feel the time. It has a button on one side where the settings can be changed. A visually-impaired person can feel the screen for an embossed application depicting the time. Good design.
