Selecting Wearable Devices using AHP

By Elias Montini | Wednesday, June 01, 2022

15 minute read

Adopting wearable devices is crucial in Industry 5.0 applications, where humans become part of the digital representation of the factory, the so called Human Digital Twins. However, the selection of the devices to use turns to be cumbersome for practitioners and researchers, because of the wide availability of devices in the market.

We faced this criticality while adopting Clawdite in a real-world application, where the aim was to monitor worker’s physiological data so that to enhance the human-in-the-loop control of a production system.

We thus defined a methodology to support the devices selection, focusing on wearable devices for Industry 5.0 applications. The methodology is based on the Analytic Hierarchy Process method, and it allows us to successfully identifying the two devices that satisfy our needs the most, among a list of 110 alternatives.

Here below we report the list of the 89 devices we ranked using our methodology (we discarded obsolete devices and those not fitting the application requirements from the initial list of 100 devices). The top-20% devices are highlighted.

Wearable Classification

Notes

Cells with value = X: the device provides the feature.
Cells with empty value: the device *does not" provide the feature, or the information is missing.
The Internal storage is measured in hours [h] (unless otherwise stated), meaning that the device can record data for the specified number of hours before saturating the internal storage.
The Weights AHP row reports values only for features we considered as primary features in our study.
