Guopeng Liang and Yun Li design students from the University in China have built Tikk-Tekk Rainbow, a novel and low-cost universal measuring device that uses visual, auditory and tactile feedback for measuring an object and is particularly designed for visually impaired individuals. It features two rubber plastic rings that you slip over each finger and has a string that unwinds when you’re trying to measure something. The device makes a “tikk” sound every 1cm and a “tekk” sound every 5cm, while the digital display and the embossed Braille numbers also provide measurement results.
