Technologies to Monitor and Promote sustainable Health Behaviour

Smartphones have become an integral part of our daily lives. On the way to work, at school, university, or during leisure time, our gaze often and almost automatically falls on the smartphone display. These devices offer many advantages: they facilitate communication, provide access to information, and serve as platforms for social interaction. However, intensive smartphone use also has its downsides, especially when it comes to our productivity and mental health. Research has shown that excessive smartphone use can lead to stress, distraction, and a decline in well-being.

A "digital detox," or the conscious reduction or abstention from the use of digital devices, presents a potential solution to mitigate the negative effects on well-being and mental health. Such breaks can be achieved by simply putting the smartphone away or through technological support like apps that monitor usage time. However, research shows mixed results: some studies have found that such breaks help improve well-being, while others have noted negative consequences, such as increased anxiety during the smartphone break. This indicates that better strategies are needed to promote healthy smartphone use.

This is where the TEMPHEALTH project comes in: the project aims to help individuals develop strategies to improve their smartphone use and to plan and reduce their daily smartphone usage duration.

In collaboration with the School of Computing & Information Systems at the University of Melbourne, we also aim to explore technical solutions through apps. Users will be supported by subtle prompts or nudges to become more aware of their smartphone usage behaviour, especially in relation to digital media consumption.

The goal of the TEMPHEALTH project is to investigate how healthy smartphone use can be promoted through the collaboration of the fields of Computer Science and Psychology
