The document proposes the WonderWatch, a wearable device and app to promote child safety. The device would allow parents to know their child's location, discreetly send and receive short messages, and activate an emergency call. It is intended for children ages 7-12 who have some unsupervised time but cannot use a cellphone. The prototype design includes a simple watch-like wearable and paired smartphone app. An evaluation plan outlines testing the device and app with children and parents to ensure key criteria are met.
