A smart health device to measure waist circumfence

Although the body mass index is a frequently used measure for overweight and obesity, the waist circumfence is a more reliable predictor for cardiovascular risks. However, while the first one can easily be digitally monitored using networked body scales there is no solution yet for the latter. We therefore present a smart measuring tape system that supports the user in taking consistent measures of the waist circumfence and stores the measures digitally. The system comprises a smartphone app and a digital measuring tape. An LED based interface helps the user in conducting the measurements. Users found the system easy to use and interesting.
