01

Can't see the problem

People know bad posture is harmful, but can't tell what's wrong with their own setup.

02

No clear first step

Even when they want to fix it, they don't know where to start.

03

Experts cost too much

Professional assessments exist, but they're too expensive and inconvenient for everyday use.

What worked

• Using a pattern people already know. The crosshair and plus button for measuring feels like the iPhone Measure app, so people knew what to do.
• Testing with real people. Two rounds of testing changed the measuring and results screens.

What I'd do differently

• Show what score range counts as a good setup.
• Add a small section about why ergonomics matters for health, so the app teaches people as well as measures.
• Make the transparent progress bar on the measure screens easier to read.

If this shipped, I'd measure

• Whether people understand their score and know what to fix first.
• Whether people come back to scan again and see their score improve.

01

Signals we misread

Interoception is how your body senses its own state, like heart rate, breathing and muscle tension. Most people feel these signals but misread them.

02

Out of reach at night

Some of the richest signals happen while we sleep and dream, so we never see them.

03

Who it's for

Health-aware adults, around 20 to 50, who want to understand what their body is doing while they sleep.

Privacy

No third-party data sharing. All sleep and body data stays on your device, protected by Face ID or a password, and you can delete it any time.

Content

Dream imagery is checked before it reaches you. Violence, trauma and explicit content are never generated. Built dreams are limited to 2 a month to protect natural sleep, and you can stop or change a dream at any point.

Wellbeing

If signs of distress show up in your sleep data, the app offers a gentle check-in. It is not a diagnosis, and crisis resources are always one tap away.

Participants

5 Interaction Design students who already use Stu-View. Average familiarity was 3.6 out of 5.

Setup

In person on campus, using Safari on my MacBook. About 20 minutes each, with the screen recorded.

What I measured

Task success, time on task, critical and non-critical errors, difficulty ratings, and what people said while thinking aloud.
