BACKGROUND

The pervasive use of smartphones has led to increased connectivity but also heightened levels of distraction and stress. While the Do not Disturb (DnD) mode was introduced to mitigate these issues, its current implementations often lack the sophistication needed to effectively balance connectivity and focused work time. This study explores the potential of an enhanced DND feature, termed "Exceptional Apps Notification," which allows users to receive notifications from selected apps while silencing others, aiming to reduce stress and improve focus.

OBJECTIVE

The primary objective of this study was to evaluate the impact of a modified DND mode on users' stress levels, productivity, and overall satisfaction. Specifically, we aimed to assess whether a personalized DND mode could alleviate concerns about missing important notifications while promoting periods of focused work.

METHODS

A mixed-methods approach was employed, involving user testing with a working prototype, structured questionnaires, physiological feedback, and semi-structured interviews. The study included 130 participants: 50 students, 60 professionals, and 20 retirees. Participants interacted with the prototype, which allowed them to customize notification settings and schedule DND activation. Data were collected through the I-PANAS-SF questionnaire, user experience surveys, and smartphone tracking apps to measure stress levels, productivity, and app usage patterns. Quantitative data were analyzed using SPSS, while qualitative data were coded and analyzed using ATLAS.ti 9.

RESULTS

The results indicated significant improvements in stress reduction and productivity. Specifically, 82% of participants reported a decrease in negative emotions such as nervousness and anxiety when using the modified DND mode. Additionally, 75% of participants reported higher levels of positive affect, including increased focus and determination. Physiologically, participants exhibited reduced stress indicators, such as lower heart rate variability, during DND activation. Productivity metrics showed a 28% decrease in phone unlocks during focused work periods and a 35% increase in time spent on productivity apps. Social media usage during work hours dropped by 42%. User experience surveys revealed that 88% of participants found the modified DND mode intuitive and user-friendly, with 82% expressing increased confidence in managing notifications. Furthermore, 91% of participants appreciated the ability to manage notifications effectively without feeling overwhelmed.

CONCLUSIONS

The findings suggest that a personalized DND mode, such as the "Exceptional Apps Notification" feature, can significantly reduce stress, enhance focus, and improve user satisfaction. By allowing users to selectively receive notifications from important apps, the modified DND mode addresses the psychological burden of constant connectivity and mitigates the fear of missing out (FOMO). These results have important implications for smartphone interface design, highlighting the need for more customizable and context-aware notification systems. Future research should explore long-term effects and further customization options to optimize user experience and productivity.
