Developers, tech industries, and researchers are designing and creating apps for achieving "digital wellbeing" with smartphone. Through usage statistics, timers, and automatic blockers, users can take advantage of such Digital-Self Control Tools (DSCT) to self-regulate their smartphone behavior. However, people typically use more than one type of device, e.g., tablets and PCs, and use them in a concurrent way, thus motivating the need of exploring digital wellbeing in a multi-device setting.

The thesis aims at defining and evaluating self-control strategies suitable for multi-device contexts. Understanding how to design multi-device DSCT, in particular, may allow users to enhance their digital wellbeing, not only with their smartphone, but with different devices in different places, contexts, and goals. 

In details, a the work plan for the thesis includes:

  1. to define, in a rigorous way and through a literature analysis, which self-control strategies can be adopted in a multi-device setting. Understanding which devices should be especially considered in such a multi-device setting is an important part of the definition.
  2. to develop some software tools to implement some of the defined self-control strategies in a few dedicated multi-device settings. This may entail the detection and collection of multi-device digital habits, as well as the proposal of possible tools and methods for end-users able to mitigate or avoid the most "negative" habits. 
  3. to evaluate the developed tools with an in-the-wild user study, if possible.
