Digital Detox by Design: Evaluating a Lockable Box for Mindful Technology Use

Abstract

Excessive, absent-minded, and aimless use of a smartphone can have a negative impact on both physical and mental health, with the potential to develop into an addiction. Because compulsive behavior can be triggered by the mere presence of a smartphone, conventional screen time management apps often fail to address this issue. We conducted expert interviews with therapists that revealed the potential of a few hours of abstinence with smartphones. Consequently, our research aims to offer a tangible physical opt-out solution while maintaining users’ autonomy to effectively reduce screen time. We designed a “mindful box” with a locking mechanism to securely store away digital devices. The box includes features that encourage intentional use, including gentle wake-up, meditation support, and cheer lists. In a one-week study with seven participants, the mindful box significantly reduced average screen time (p = 0.016). Users praised its effectiveness in combating distractions and limiting excessive device use.
