In this study, my fellow students and I investigated how using split-screen multitasking compares to the traditional way of switching between apps on smartphones during travel planning. We used a between-subjects design, meaning that all participants completed the same task, but one group used the split-screen functionality while the other group relied on regular app switching.
Our findings showed that using the split-screen functionality helped participants complete the task faster, without reducing accuracy. Although participants generally gave positive feedback about its usability, their willingness to adopt this feature varied. This suggests that while split-screen can be beneficial, there is a need for more customizable mobile interfaces to better match individual user preferences.

- Data preprocessing (timing extraction, error coding) and conducted statistical analysis (t-tests).
- Coordinated group work by setting deadlines, dividing tasks, and facilitating collaboration.
- Co-wrote the report.
Skills & Tools
- User research & experimental design
