The increasing demand for product customisation is leading to higher complexities within industrial systems. This imposes new challenges for the workforce. One way to support operators' productivity may be context-aware, human-centred cyber-physical assistance systems. Human Activity Recognition (HAR) is a promising approach to enable context-awareness. However, standardised approaches to integrate HAR into existing industrial environments are rare. Particularly, there is a lack of available

This work therefore proposes Methods-Time Measurement (MTM) as a standardised foundation for creating an industrial activity dataset. Subsequently, five different machine learning algorithms are tested for their recognition performance based on the dataset captured with an inertial sensor suit and an RGB-D sensor. A proof-of-concept is delivered for both sensor categories applied to the scope of 18 MTM-1 activities, whereas inertial data outperformed depth data. K-Nearest Neighbour and Bagged Tree algorithms revealed the best classification accuracy results in this context.
