Calm Technology: Principles and Patterns for Non-Intrusive Design
Designing for the Next 50 Billion Devices
"Designing Calm Technology": understanding the impact of technology on people's behavior and well-being
Edge Cases: unpredictable problems that arise at extremes
- oftentimes are discovered after products are launched > Example: Running shoe might work well on typical pavement, but melt on track material on very hot summer days
The physical technology that we live with and rely on daily must be resilient enough that it can work regardless of whether or not it's connected to a network
We can help make the future more reasonable by writing efficient code, using lower-level languages for mission-critical systems, and creating more local networks
Principles of Calm Technology
I. Technology should require the smallest possible amount of attention.
- A lot of connected technology doesn't "just work" right out of the box
- Consider doing away with an interface or screen entirely, replacing it with physical buttons or lights > Example: MacBook power cord > - Primary information system: Light indicator > - Secondary information system: Visual display
II. Technology should inform and create calm.
- Technology can create calm by letting you know definitely that a system is functioning correctly and all is well
- Calm comes from knowing that you'll be alerted at the appropriate time if something needs to be addressed
III. Technology should make use of the periphery.
- When a technology forces a low-resolution update into the high-resolution space of your full attention, it wastes your time, attention, and patience
- Using touch, sounds, and peripheral vision opens up our sight to focus entirely on the road while doing secondary tasks in our periphery > Example: Van Halen's brown M&M's verified if a venue read the technical aspects of their show
IV. Technology should amplify the best of technology and best of humanity.
- The best tech amplifies the best of both machines and people
- The best interfaces connect us to other people
- Amplify the tasks that humans are better than machines
V. Technology can communicate, but doesn't need to speak.
- As voice-based interfaces become more common, it's worth addressing the problems with voice interaction specifically
- Making a computer speak like a human without instilling it with a series of human context or relationships ultimately leads to a sense of dissonance in the person using it
- A user interface requiring all of our visual focus distracts us from doing anything else
- A simple positive or negative tone, symbol, or light can be designed in a way that's universally understood > Example: Not "Launch the Octopus"
- Use a status tone instead of spoken voice.
- Use a buzz instead of a voice-based alert.
- Use a status light instead of a display
- Sometimes having two notifications is useful, as it increases the likelihood of user noticing it without demanding their full attention
VI. Technology should work even when it fails.
- The problem with edge cases is that their impact outweighs their frequency
- The key to dealing with edge cases is providing redundancy
VII. The right amount of technology is the minimum needed to solve the problem.
- Good designers aren't afraid of working through all the tiny details and all the edge cases they can conceive, removing unnecessary features until there is nothing left to take away
- Empowering the user to get their goal with least amount of attention
- "Is this something necessary to the product?"
VIII. Technology should respect social norms.
- One that conforms with existing norms, or (more often) norms have adjusted to accept ___
Common Communication Patterns
- Heat light on a stove
- Bedtime lamp
- Server status light
- Light-based faucet
- Light-up toothbrush
- Self-inflating inhaler
- Help button on a plane
- Washer and dryer with a melody
- Insulin pump
- Roomba vacuum cleaner
- Haptic Alerts
> Physical notifications that can be felt on body
- Feedback from video game controller
- Buzz on a smartphone
- Smartwatch alert
- AMBER alert or emergency alert
- LUMOBack posture sensor
- Turn-by-turn directions
- Seat belt on/off alert
- Smoke detector
- Parking garage warning buzzer
- Emergency vehicle truck siren
- Recess bell
- Lavatory occupied sign
- Directional tape on a floor
- Weather-colored lightbulb (conceptual)
- Email Garden (conceptual)
- Emotional and metabolic state
- Alpha wave synchrony feedback machine
- Withings scale
- Toyota Prius driver feedback
- Salad bar tongs
