Overview

Sense Stone is a concept project exploring how AI can support Gen Z wellbeing through touch, with minimal screen use. It centres on a small tactile device, calibrated via a conversational AI app, that adapts to the user's mood and environment. Once calibrated, it guides mindful breathing through subtle haptic feedback and gentle expansion, designed to support emotional regulation through research-backed breathing techniques. Inspired by the 'SENSESCAPING' trend (Trendwatching), and work by Modem (Terra) and Morrama (AI Mindful Tools), all of which highlight a shift towards responsive, low-screen wellbeing experiences.

UX PROBLEM

Gen Z users are interested in mindfulness but struggle to maintain consistent habits due to digital distractions and time pressure. This creates a gap between intention and action.

DESIGN STRATEGY

Design a responsive, screen-light breathing companion that makes mindful, emotion-regulating practice effortless and low-distraction.

FRAMEWORK

Based on ISO 9241-210, the project follows a human-centred design process: understand context → define requirements → design → test → iterate.

TARGET AUDIENCE

Gen Z (18–28) individuals interested in improving mental and physical wellbeing, including those managing anxiety, who value AI-supported guidance that feels trustworthy, simple, and non-intrusive

Research (secondary + primary) explored user behaviour, environments, and existing solutions to define needs, pain points, and the core UX problem.

  • 1 in 3 adults aged 18–24 in the UK, experience anxiety or depression — now the most affected age group.

The AI Opportunity

65% of Gen Z trust AI (but there are doubts over accuracy, trust, as well as the risk of being overly reliant on tech)

Insight→ Keep AI simple and transparent

The Daily Struggle:
  • Juggling university deadlines with social pressures.

  • The ‘Doom-Scroll’ Cycle: Uses phone for procrastination.

The Digital Trap:
  • Reliance on phones for everything...alarms, calendar etc. makes ‘digital detoxing’ hard.

  • Most attempts to ‘be mindful’ are broken by notifications.

The Tactile Gap:

  • A grounding tool that can be used discreetly ‘under the desk’ or in a library.

  • AI that proactively predicts stress moments.

Success Defined:

  • Shifting from ‘reactionary stress’ to ‘proactive focus’ in under 60 seconds.

  • Gaining a sense of agency over their mental state away from the screen.

Insight → Users struggle to regulate their emotions because distraction is always more accessible than control. Solutions must protect their attention and guide them towards what they actually need in that moment.

Competitor Analysis

No solution currently combines a physical device with real-time conversational AI to guide breathing- adapting to users' emotions and supporting regulation, especially for this overlooked age group.

Regulated Breathing Benefits:

Research suggests regulated breathing reduces stress and improves physiological calm via parasympathetic activation.

Tactile Practices:

Hand-held objects (e.g., worry beads, stress balls) have been used for grounding, showing multi-sensory approaches support emotional regulation.

Smartphones & Mental Health:

Recreational screen time over 2 hours daily has been linked to declining mental health in young adults.

How do you feel now?

App User Flow

The app uses a minimalist, screen-light design with optional account creation and error-proof pairing to minimise friction. The MVP flow (in colour) prioritises core uses including device connectivity. Paths in grey map future iterations designed for long-term retention, including a Library for saving exercises, a Profile for mood logging, and Settings for adjusting haptic strength.

Onboarding

Onboarding lets users grasp how Sense Stone works, provides transparency on AI data use, and guides them to create an account.

Phase 4: Evaluation Methods

Phase 4: Evaluation Methods

Research (secondary + primary) explored user behaviour, environments, and existing solutions to define needs, pain points, and the core UX problem.

Early User Feedback

Five potential users were shown the device visualisation and an interactive app prototype, with interactions explained. Using a think-aloud approach, insights were recorded as users shared suggestions, ideas, and thoughts about the concept.

“I like that it gives me an exercise that fits how I’m feeling in the moment. That actually might make me feel better.”

“The branding feels calming, but I’d want to make sure the app has a dark mode.”

“I’m curious what the device feels like- I’d want to try it first before deciding if I’d use it.”
