Jason Fried argues that the original Cuisinart food processor is a near-perfect example of interface design. Its two large paddle buttons, one latching for continuous ON and one spring-loaded for momentary PULSE/OFF, make the controls intuitive once used, even though they sound complicated described. The buttons offer clear affordances, tactile feedback, and generous surface area that works with bare hands or messy, gloved fingers. Fried's point is that good design often feels obvious in use, and that many later appliances have declined from this standard.
01Key takeaways
- Judge an interface by how it works in use, not by how complicated it sounds when described.
- Give controls clear affordances so people know how to operate them without instruction.
- Provide tactile and audible feedback that confirms a control's state, such as latched versus released.
- Design for the real conditions of use, including gloves, wet hands, and distracted users.
- Prefer a minimal set of controls that cover all needed modes rather than adding more buttons.
02Key sections
- A two-button control scheme
- The ON button latches for continuous running, while the PULSE/OFF button springs back when released. Together they cover every operating mode with just two controls.
- Obvious in use, not in description
- The dual-purpose PULSE/OFF button sounds convoluted when explained, but it becomes immediately clear when someone actually uses it.
- Affordances and tactile feedback
- Big flat toggles under spring tension signal how they should be pressed, and the audible, tactile click tells the user whether a button has latched.
- Designed for real-world conditions
- Large surfaces let the buttons be operated with bare hands, oven mitts, or slippery fingers, showing consideration for the actual context of use.
- A decline from a high bar
- Fried's closing remark suggests that interface quality has deteriorated since this design, implying that simplicity and clarity have been lost in later products.
03From the post
“The original Cuisinart was peak interface/appliance design. Two perfect paddle buttons. One for ON that catches and stays down for continual operation. And one for PULSE/OFF that does exactly what it says. It doesn't stay down, it returns to reset when you let go. Hold it down as long as you want to pulse. Let go and it stops. Or…”
