High stress

AI-given
permission
to leave

People with social anxiety often can't decide to leave when they're overwhelmed — not because they don't want to, but because social pressure outweighs their internal discomfort.

SoftSignal is an AI-assisted system that monitors physiological stress signals via a smartwatch — heart rate variability, tension patterns — and delivers a discreet, dignified prompt before overload: it's okay to leave now.

Prototyping insight
📈
Social anxiety is a gradually escalating overload

In stressful social situations, people focus on their own nervous feelings rather than their surroundings. Crowds create escalating discomfort and loss of control, not sudden breakdown. Cognitive and attentional shifts precede full anxiety episodes.

🔔
Early awareness exists, but action is delayed

Users notice subtle internal cues — tension, fatigue, increased vigilance — before social overload. These cues are frequently minimized: 'I should be fine' or 'it would be rude to leave now.'

🔒
Wearables can detect stress, but privacy matters deeply

Heart rate variability changes are reliable signals of emotional overload. But users raised concerns about misreadings, privacy, and feeling controlled by AI — revealing the opportunity: AI support must feel like a suggestion, not a directive.

Userflow Storyboard

Jack's night out

01
Invited to a party

A friend invites Jack to a party tonight. He dresses up and puts on his smartwatch before heading out.

02
Socializing — all good

The party starts well. Jack mingles and enjoys himself. His watch shows 12% pressure — all good.

03
Stress begins to build

As the night goes on, the crowd grows. Jack feels increasingly tired and overwhelmed. Pressure climbs to 70% — the watch vibrates gently.

04
SoftSignal nudge arrives

The watch delivers a soft vibration pattern and a gentle prompt: 'Your signal says now might be a good time to leave.' A suggestion, not a command.

05
A pressure-free goodbye

Jack calmly says goodbye to his friends — 'Sorry guys, I have to go.' No over-explanation needed. No guilt.

06
Home to rest — intact

Jack gets home. The app logs the session data. He feels like he took care of himself — not that he ran away from something.


Calm,
quiet
interface

Prototyping confirmed a core principle: at the moment of sensory overload, a clear and empathetic message is worth far more than complex data or a polished UI. SoftSignal's interface is deliberately minimal — a pressure reading, a short message, one action.

Mobile App
Companion mobile app

The mobile app shows live pressure status and a history of past social events — each with duration and peak pressure. Users review data after the fact to build self-awareness, not stare at a screen in the moment.

What the
paper prototype
revealed

Watch Wizard of Oz Video
01
UI structure and hierarchy

Testing confirmed that people make more errors under pressure. At the moment of sensory overload, a clear, empathetic message is worth far more than complex data or a polished UI — driving the decision to keep the final interface radically minimal.

02
Interaction flow and privacy

Analyzing the full interaction flow — from watch vibration patterns to notification messages to data collection — confirmed that privacy is paramount for this user group. AI prompts must feel like a gentle suggestion, never surveillance or control.

03
Feature scope and prioritization

Testing revealed that emotional validation and tone matter far more than features like stress explanations or future recommendations. Users at high-pressure moments need to feel accepted — not analyzed.
