Multi-criteria analysis of wearable activityfitness trackers and 3D concept models of smart jewellery

摘要

The technological development of wearable activity tracking devices with a whole range of functions is considered in this paper. Experts from different decision-making groups performed the multiple attribute evaluation of three devices for heart rate, exercise and sleep monitoring: a watch, a bracelet and a ring. MCA is applied to determine the relative weights of evaluation criteria. The result shows that the ring is the most suitable tracker that fits seamlessly into everyday life. Following the result, several 3D models of smart jewellery are presented for rapid prototyping.
