Thus, the goal of this bachelor project is to develop a documentation app that includes different data engineering steps. Documentation and planning of patients’ treatment can be very extensive and time-consuming . It comprises up to 30% of the working time, which can be reduced by using machine learning (ML) models. The recognition and data mining of nursing activities can lead to a better understanding and improvements in medical care, and it can help prevent unnecessary and excessive work.
In that regard, the project’s objectives are as follows:
- Development of a mobile app that automatically recognizes nursing activities.
- Evaluation and improvement of an ML model to classify the different nursing movement patterns.
Sensor-based activity recognition integrates the emerging field of sensor networks with novel data mining and ML techniques to model a wide range of human activities . Accelerometers and angular rate sensors provide sufficient data and computational power to enable activity recognition. However, due to the inherent noisiness of the input data, this is a challenging task. Especially, the inflection pattern of nursing activities are more complex . Therefore, a set of operations aimed at creating interfaces and mechanisms for information flow and access is necessary. As shown in the figure above, where sensor data is collected, this project involves data transfer; data pre-processing; on-device, real-time classification of different activities; and the development of a mobile app for nursing documentation. This project will touch different programming languages and technologies like Python, Tensorflow Lite to enable on-device machine learning, and Flutter/React Native to build a mobile application that can access the TensorFlow Lite interpreter and perform inference.
