“Who moved my heart brush?” Realms of the Heart: A Human-AI Collaborative Gamified Adjuvant Treatment Application for Depressed Teens Based on Painting Therapy

Key findings from this study

This research indicates that:

• Gamified human-AI collaborative painting therapy increased motivation and significantly reduced depression severity in adolescents compared to control conditions.
• Natural object transformation into digital brushes and AI-generated sketch production created meaningful engagement mechanisms in a therapeutic context.
• AI co-creation within art therapy design can address specific barriers to engagement such as low self-confidence and self-absorption in depressed adolescents.

Overview

Realms of the Heart is a gamified human-AI collaborative system designed as an adjuvant treatment for adolescent depression. The application integrates painting therapy with AI-driven features that transform natural objects collected during exploration into digital brushes and generate sketches using ControlNet. Development followed need-finding investigations addressing documented challenges in painting therapy engagement among depressed adolescents, including low self-confidence and self-absorption.

Methods and approach

A randomized controlled trial compared an experimental group using Realms of the Heart against a control group. The system incorporates two core AI strategies: object-to-brush transformation based on teens' environmental exploration, and sketch generation aligned with selected brushes via ControlNet technology. The design addressed specific barriers to engagement identified in preliminary investigations of painting therapy effectiveness.

Results

Realms of the Heart increased user motivation and significantly reduced depression severity in the experimental group relative to the control condition. The gamified structure combined with AI-generated content and natural object integration produced measurable improvements in both engagement and clinical outcomes. These results demonstrate that human-AI co-creation within a painting therapy framework yields therapeutic benefits beyond traditional painting interventions alone.

Implications

The study establishes human-AI collaboration as a viable approach for enhancing art therapy efficacy in adolescent mental health treatment. Gamification elements paired with generative AI features can address motivational barriers characteristic of depressed adolescents undergoing creative therapies. The findings suggest that natural object integration and AI-mediated sketch generation warrant consideration in designing adjuvant mental health interventions for this population.

Future art therapy applications may benefit from similar hybrid human-AI frameworks that maintain therapeutic foundations while leveraging algorithmic customization and engagement mechanics. The research direction implies broader potential for AI-assisted personalization in psychosocial treatments, though implementation in clinical settings requires further investigation of sustainability and long-term outcomes.
