Sketching and paper prototyping create low-fidelity, hand-drawn representations of interfaces to explore and test ideas. The low fidelity signals to users that the design is not final — actively encouraging honest, critical feedback.
Before wireframing or digital prototyping, whenever you want to test a concept quickly without the cost and commitment of digital design.
- Draw the key screens or steps on paper — boxes and labels are enough
- Simulate interactivity by swapping paper screens as the user 'clicks'
- Give users a specific task to complete — don't explain the interface
- Observe silently: where do they hesitate, click the wrong area, or express confusion?
- Note observations without intervening
- Iterate the sketch immediately after each session
Paper prototype of a redesigned 'Now Playing' screen with a context label showing why a song was recommended. Task: 'Find out why this song is playing.' Observation: 3 of 5 users tap the album art — they expect the explanation to appear there, not in a separate UI element. Immediate design fix: album art tap reveals the context.

- Making the prototype too polished — users won't give honest feedback if it looks finished
- Explaining the interface when users get stuck — their confusion is the data
- Waiting too long to test — every week of delay is feedback you don't have
