Wearable Devices for Ergonomics: A Systematic Literature Review

Area of Science:

• Ergonomics
• Human-Computer Interaction
• Wearable Technology

Background:

• Wearable devices offer pervasive solutions for enhancing work efficiency and well-being.
• Existing research lacks systematic reviews on wearable device utilization specifically within ergonomics.
• A comprehensive understanding of smart wearables in ergonomics is needed to guide selection and future research.

Purpose of the Study:

• To systematically review and identify wearable devices proposed for ergonomic applications.
• To analyze how these devices can support the improvement of ergonomic conditions in various settings.
• To provide an overview of the state-of-the-art smart wearables in ergonomics.

Main Methods:

• Systematic literature review of 28 retrieved papers.
• Analysis based on eleven comparison dimensions covering ergonomic factors, purposes, criteria, populations, application, and validation.
• Categorization of identified wearable devices and their functionalities.

Main Results:

• The majority of identified devices are sensor systems, often body-mounted.
• Sensor systems are frequently used for monitoring and reducing the risk of awkward postures.
• Smartwatches, smartphones, insole pressure systems, and vibrotactile feedback interfaces are developed for evaluating and controlling physical loads and postures.

Conclusions:

• Smart wearables, particularly sensor systems, are pivotal in advancing ergonomic assessments and interventions.
• The findings support informed selection of wearable technology for both industrial and non-industrial environments.
• Future research should focus on further developing and validating these technologies for enhanced ergonomic outcomes.
