Tikk-Tekk Rainbow is a low-cost universal measuring tool for the visually impaired that uses visual, tactile, and auditory feedback. A rubber plastic ring slips over each index finger. As the measuring string unwinds, the device makes an audible "tikk" sound at every centimeter and a "tekk" sound at every five centimeters. Printed digits and embossed Braille numbers also provide measurement results.
