Designing for Long-Term Emotion Regulation: A Breathing Biofeedback Game for Women in Compulsory Isolation Drug Rehabilitation Centers
A strong CHI contribution: it pairs a clearly specified low-cost breathing biofeedback game with a six-week controlled study in a rarely studied, high-constraint population, showing that carefully phased and metaphor-rich design can support engagement, skill transfer, and emotional benefit while still leaving important measurement and generalizability limits.

Review Summary
This is a compelling best-paper-level contribution because it does more than present another wellness game or another short breathing intervention. The paper identifies a neglected HCI problem space: women with substance use disorders living in compulsory isolation rehabilitation centers, where emotion regulation is crucial, stigma is high, cognition may be impaired, and conventional interventions can be resource-intensive or poorly matched to everyday needs. Against that backdrop, the authors build a concrete artifact rather than stopping at needs assessment. The system is notable for its pragmatic technical stance—using standard microphone input instead of specialized sensors—and for its psychologically intentional design, especially the phased seven-day structure and the narrative and growth metaphors meant to reinforce agency, self-acceptance, and sustained participation. What makes the paper especially persuasive is the coupling of design rationale with longitudinal evaluation. In the provided sections, the authors clearly frame prior work as concentrated on non-SUD populations or short-term lab studies, then report a six-week controlled study with 60 participants showing changes in breathing-related behavior, flexible real-life application, and shifts in anxiety and depression. That gives the contribution more weight than a pure prototype paper. The work also matters methodologically and ethically for HCI because it demonstrates how digital interventions can be adapted for marginalized users in constrained institutional settings rather than assuming mainstream consumer contexts. At the same time, the paper does not eliminate uncertainty. The provided evidence shows explicit measurement limitations and a non-medical sensing approach, so the strongest claims should remain about behavioral support, engagement, and self-reported emotional outcomes rather than fine-grained physiological regulation. Generalization is also bounded by the specific gendered, cultural, and institutional setting. Even so, the paper advances the field meaningfully: it offers a credible artifact, a meaningful evaluation, and design knowledge about long-term emotion-regulation support where HCI has had relatively little grounded evidence.
What Changed
Canon before
Dominant assumptions before this work include that breathing interventions for emotion regulation among substance use disorder populations are usually short-term, often therapist-dependent or group-based with uniform pacing and limited feedback, and that long-term skill transfer especially in constrained, marginalized, and closed rehabilitation settings is underexplored. Existing breathing biofeedback games are mostly short-term lab or clinic studies focusing on general populations and do not address the particular cognitive, emotional, and social challenges faced by women in compulsory isolation drug rehabilitation centers. Also, common sense suggests that digital interventions risk over-dependence and that social stigma and cognitive impairment severely limit learning in these populations.
Departure from common sense
This work pushes against the expectation that breathing interventions for people with substance use disorders are mainly short-term, generic, or hard to transfer into everyday practice. The paper argues that a phased, game-based, biofeedback-supported design can sustain engagement and support flexible use of breathing skills beyond the intervention week, even in a constrained compulsory rehabilitation setting. It also challenges the idea that such populations are poor candidates for self-directed digital emotion-regulation tools by showing a design tailored to shame, low self-esteem, and cognitive impairment.
Actual novelty
The paper’s main novelty is a seven-day phased breathing biofeedback game for women in compulsory isolation drug rehabilitation centers that combines low-cost microphone-based input, psychologically grounded visual feedback, and narrative metaphors aimed at self-efficacy, self-acceptance, and long-term engagement. The contribution is not just the artifact itself but its empirical demonstration in a six-week controlled study showing sustained engagement, improved breathing skill mastery and transfer, and reduced negative emotions, plus design implications for marginalized populations in closed environments.
Evidence
The available grounded evidence supports four core claims: the paper explicitly positions itself against prior short-term and non-SUD-focused breathing game work; it describes a concrete 7-day system architecture with low-cost microphone input and psychologically based feedback; it reports a six-week controlled study with 60 participants and outcomes on breathing behavior and self-reported anxiety/depression; and it explicitly acknowledges measurement limitations and future directions. Evidence is strong for the existence of the artifact and study scope, but some broader interpretive claims remain bounded by the single institutional context and limited physiological measurement.
“ However, existing work has primarily focused on people without SUDs or short-term laboratory studies [36, 45, 111, 116], with limited attention to the long-term transfer of emotion regulation skills among individuals in recovery, or to the unique demands of rehabilitation environments shaped by cultural and institutional differences [77]. For instance, in many European countries, ”

Limits
Method limits
The paper explicitly notes measurement limitations. The system does not aim for medical-grade sensing and only detects inhalation, exhalation, and duration rather than richer physiological parameters. Quantitative outcomes highlighted in the provided sections emphasize self-reported anxiety and depression plus breathing-related behaviors, so psychophysiological interpretation is limited.
Deployment limits
The intervention is designed for women in compulsory isolation drug rehabilitation centers in China and depends on a low-cost microphone-based setup and a structured 7-day program embedded in that institutional context. Transfer to other populations, settings, or post-discharge life is not established in the provided evidence.
Boundary conditions
Claims are bounded to women with substance use disorders in a compulsory rehabilitation environment, to a seven-day phased intervention followed by five weeks of follow-up, and to a low-cost non-medical sensing approach. The strongest supported generalization is to similar marginalized populations and constrained environments rather than to all emotion-regulation or addiction-recovery contexts.
Position in field
This paper sits at the intersection of HCI for digital mental health, biofeedback game design, and design for marginalized populations. Its field contribution is to extend breathing-biofeedback work from short-term, often general-population studies toward long-term skill transfer in a closed rehabilitation setting, while also articulating design implications around motivation, dependence reduction, contextual fit, and design justice.
