Evaluation of a Smartphone-based Human Activity Recognition System in a Daily Living Environment

What is it about?

This paper presents a circuit of activities that can be used as a standardized evaluation method for the performance evaluation of Wearable Mobility Monitoring Systems (WMMS). The circuit that includes continuous activities in a realistic daily living environment and includes many movements that are realistic (e.g. hair brushing, food preparation), yet can often confuse WMMS algorithms.

Why is it important?

Interest in Human Activity Recognition based on smartphone data has exploded in recent years. However, all researchers use their own test data, the protocol of which is not standardized, thus making comparison of results between different research groups near impossible. In this paper, we proposed a circuit to encourage all researchers to include realistic movements to enable comparison across research performed in this field.
