One-minute digital prompts boost healthy habits via co-authored personalization

A new paper from a team led by Zahra Hassanzadeh explores how one-minute digital interventions can spark immediate action across domains like physical activity, healthy eating, and mental well-being. Drawing on Fogg's Behavior Model and four design principles from HCI literature, the researchers created prompts so simple that even people with low motivation would attempt them—no onboarding or sensing required. The 14-day study with 22 participants tested these prompts and found that co-authorship—letting users personally rewrite the prompts—emerged as a lightweight personalization mechanism. This method increased relevance without adding friction, outperforming generic one-size-fits-all nudges.

The paper, submitted to arXiv and classified under Human-Computer Interaction, provides a practical framework for embedding tiny, effective interventions into everyday digital tools. Instead of relying on complex data collection or user profiles, co-authorship empowers individuals to tailor prompts to their own context—a technique that could scale across apps, wearables, and smart assistants. For tech professionals, this suggests a new design pattern for habit-forming products: shift from push notifications to collaborative prompt co-creation, potentially improving engagement and long-term behavior change without compromising privacy or requiring heavy computational resources.
