Mind Ocarina

“Reimagining calmness through embodied interaction.”

A tangible HCI system that turns breathing into a sensory ritual for emotional self-regulation. Shaped like an ocarina and inspired by the Eastern symbolism of the Moon Rabbit, it bridges physical embodiment and digital serenity — calmness as something you do, not a passive state.

The device pairs an airflow sensor with ear-glow light, aromatic diffusion and ambient tones; a companion app with a rabbit character mirrors each breath and rewards consistency without pressure.

01.Background

Digital overload severely impacts productivity and mental health. During a 2024 summer in the marketing department of a Beijing internet company I watched colleagues burn out while maintaining a constant digital presence across Reddit, Quora and WeChat. It is a local instance of a global pattern: the inability to disconnect in hyper-connected workplaces.

I wanted to investigate how calm technology and ritual design can foster digital wellbeing, bridging technological presence and the fundamental human act of breathing.

02.User Research

Research ran in three passes: naturalistic data from Reddit and Rednote organised with an affinity diagram, a quantitative survey, and qualitative interviews.

01Naturalistic dataScattered community posts, affinity-mapped into four patterns defining the problem space.
02Survey, N=50Demographics and prevalence; locates the most affected segment.
03InterviewsA financial analyst, a marketing manager and a senior developer on living with hidden anxiety.
Insight 1 · DurationAcute stress events (panic attacks) are typically brief but intense, lasting approximately 1–10 minutes.
Insight 2 · Scenarios (triggers)Events are often triggered during moments of transition (e.g. commuting) or high-stakes communication (e.g. meetings, difficult calls).
Insight 3 · SymptomsThe experience is not just emotional; it is highly physical, a process known as somatization.
Insight 4 · Intervention methodsCurrent coping mechanisms are mixed, from informal strategies (“slipping away”, “distraction”) to clinical interventions (e.g. medication).

Survey, N=50

The most affected segment is young professionals: aged 26–30, full-time employed, 1–3 years into their career. Somatic symptoms are common: 88% report dizziness, 92% numbness, plus leg weakness.

Coping strategies were scored on accessibility, effectiveness, duration, consistency and social acceptability, comparing meditation, temporarily leaving and distracting attention.

Qualitative interviews

“Sometimes I have to leave the meeting. I tell people I have an urgent call, but really I’m trying to prevent a panic attack. I’ve turned down promotion opportunities because they involved public speaking. I wish there were resources that didn’t require me to publicly identify as anxious.”
Hui Liu · Financial analyst, 30
“When the high pressure hits, I don’t just feel stressed; I dissociate. My brain “flights”. I need something to immediately confirm I am safe right now. I need a physical anchor to connect back with my body and the present moment, not just another app notification.”
Qian Wang · Marketing manager, 28
“I’m extremely sensitive to sounds. If I hear a loud voice in the office, my mind just goes blank, and I feel physically suffocated. It’s not just “being sensitive”; it’s an automatic physiological reaction that I can’t control with rational thought.”
Bing Duan · Senior developer, 36

Goals
  • Regulate physical symptoms (trembling) discreetly.
  • Maintain the “professional mask” at all costs.
  • Find a coping mechanism that doesn’t require leaving the desk.
Frustrations
  • Meditation apps feel too slow and demanding.
  • Fear that visible anxiety equals “weakness”.
  • Over-analyses feedback loops.

The cycle of “hidden” anxiety

StageWhat Wei doesWhat she thinksPain point
1BracingChecks calendars, organises the to-do list, aligns items on the desk perfectly.“If I organise everything, I am safe.”
2TriggerSees a notification pop up. Freezes, stops typing, stares at the screen.“A meeting invite from boss? What did I do wrong?”Uncertainty triggers instant catastrophic thinking.
3PeakHyperventilates slightly, hands shake, unable to focus on tasks.“I am going to get fired. Everyone is watching me.”Critical gap: no tool available to arrest somatic symptoms here.
4EscapeAbruptly leaves the desk, goes to the restroom, washes her face with cold water.“I just need to get away. I will go to the restroom.”Leaving the desk confirms the “weakness” narrative.
5AftermathReturns to the chair and stares blankly. Tries to restart work but is distracted.“I wasted 30 min. Now I am behind schedule.”Loss of productivity creates secondary anxiety.

Key findings

Breakdowns are pervasive80% of participants have experienced an emotional breakdown in the workplace; 76% avoid tasks or scenarios to prevent attacks.
Real career costThe survey shows significant negative impact on interpersonal relationships and career growth.
Effective is not accessibleThere is a critical gap between the most effective coping strategy (meditation) and the most accessible ones (distracting, eating), especially during acute stress events.

03.Design Opportunity

Mapping existing stress-relief tools on a tech-intensity × scenario matrix showed they are either too obvious, too simple, or lack physical feedback. The opportunity: a subtle, multisensory phygital device that offers comforting, playful and tangible relief at the desk.

Existing tools cluster around established interaction patterns, multi-sensory feedback loops, guided breathing mechanics, haptic feedback, natural elements, focus and productivity apps, and robust feedback systems. I looked for inspiration in three directions.

1 · Interaction: tangible, breath-controlled devices

How can physical objects intuitively guide a non-physical act like breathing?

  • Ocarinas & wind instruments. An ancient and intuitive precedent for a “breath-in, feedback-out” device. The physical act of holding and breathing into an ocarina is inherently focusing and meditative.
  • Meditation tools (stress balls, singing bowls). Objects that provide tangible, haptic feedback. Their purpose is to ground the user in the present moment through a physical anchor, a core requirement for the device.

2 · Sensory: discreet, personal aromatherapy

How to make the experience multi-sensory and discreet, moving beyond just the screen?

  • Snuff bottles (鼻烟壶). A key inspiration: historic, beautifully crafted objets d’art designed for personal, portable and discreet sensory relief. They directly informed the replaceable aromatherapy pods, framing the device as a personal, elegant accessory rather than a medical tool.
  • Modern aromatherapy diffusers. These established public acceptance of scent as part of a wellness routine. The goal was to make this experience personal and portable.

3 · Gaming: “no-guilt” digital companionship

  • Finch: Self-Care Pet. The prime case study. It perfects the “care for a pet, care for yourself” model; users’ feedback that “caring for Finch taught me to care for myself” validated the companion-based approach.
  • Neko Atsume & Usagi Shima. These “Zen collector” games provided the no-guilt mechanic: success is defined by passive attraction and gentle interaction, not by stressful obligation or streaks. Essential for a product designed to reduce anxiety, not create it.

04.Iterations & Concept

Form explorations moved from penguin and bottle silhouettes to the final egg-like body, sized around an ESP32-C6 and a flow sensor. The concept is a complete ecosystem of hardware and software.

Hardware · Tactile groundingErgonomic and textured, designed to be held and fidgeted with: a physical anchor in high-stress moments.
Hardware · Olfactory integrationA replaceable scent module (lavender, bergamot) engages the limbic system for immediate physiological relaxation.
Software · Digital companionAn animated rabbit mirrors the user’s breathing pace, a non-judgmental friend rather than a clinical interface.
Software · Biofeedback loopBreathing frequency is tracked over time; progress is rewarded with items for the companion (carrots, accessories), consistency without pressure.

System. From picking the device up to collecting a reward:

01InitiationUser picks up the device when anxious and breathes into it.
02BreathingThe flow sensor detects inhale / hold / exhale and intensity; the rabbit ears glow from tip to base and gently lift.
03FeedbackESP32-C6 streams breath data over BLE every 20–50 ms; the rabbit animates in real time while notes rotate around its ears.
04GrowthCycle complete: the rabbit offers a reward and the device releases scent.

App. After connecting the device, Quick Start begins a session; users set duration and breathing pattern, and each session unlocks random rewards collected in the Album.
