“A very busy network causes a madly whirling string with a characteristic noise; a quiet network causes only a small twitch every few seconds.”— Mark Weiser & John Seely Brown, describing the Dangling String at Xerox PARC in “Designing Calm Technology”, 1995

Calm technology design principles describe how to build products that inform people without demanding their attention. The idea comes from Xerox PARC in 1995; the eight principles most designers use today were written by Amber Case. Below you will find all eight, twelve real calm technology examples from a 1995 string to 2026 certified devices, and an audit tool to score your own product.

How long people now focus on one screen, on average, before switching. That is the problem calm technology is meant to solve.

1What is calm technology?

Calm technology is technology that informs you without demanding your full attention. Mark Weiser and John Seely Brown of Xerox PARC described it in 1995 as technology that “engages both the center and the periphery of our attention, and in fact moves back and forth between the two.” It stays in the background until you need it.
Calm technology — “a method for smoothly capturing a user’s attention only when necessary, while calmly remaining in the background most of the time” (Amber Case, O’Reilly, 2015).

The key word is periphery. Weiser and Brown used it “to name what we are attuned to without attending to explicitly.” The sound of traffic outside, or light under a door, keeps you informed without asking for anything. “Thus the periphery is informing without overburdening,” they wrote, and they called calm technology possibly “the most important design problem of the twenty-first century” (Weiser & Brown, 1995).

It built on Weiser’s 1991 Scientific American article, which opens: “The most profound technologies are those that disappear” (Scientific American). A follow-up paper, “The Coming Age of Calm Technology,” is dated October 5, 1996 and was printed in 1997 in the book Beyond Calculation (Springer). Its most quoted line: “What matters is not technology itself, but its relationship to us” (calmtech.com).

Calm is not the same as invisible. Zero UI removes the screen, and ambient computing spreads technology through the environment, but both can still be noisy. Weiser and Brown also warned against calm for its own sake: “Not all technology need be calm. A calm videogame would get little use; the point is to be excited.”

2The 8 principles of calm technology

Amber Case’s eight principles say technology should require the smallest possible amount of attention, inform and create calm, use the periphery, amplify the best of technology and humanity, communicate without needing to speak, work even when it fails, use the minimum technology needed, and respect social norms.

The wording below is Case’s, from calmtech.com. The “in practice” notes are design patterns you can apply today.

# Principle (Amber Case) In practice
I Technology should require the smallest possible amount of attention Instead of an alert, update a status the user can glance at.
II Technology should inform and create calm Tell people what happened and what, if anything, they need to do.
III Technology should make use of the periphery Use light, sound or position so information moves to the center only when it matters.
IV Technology should amplify the best of technology and the best of humanity Let machines remember and calculate; let people decide and judge.
V Technology can communicate, but doesn’t need to speak A tone, a glow or a vibration often works better than a voice.
VI Technology should work even when it fails If the network drops, the product should fall back to a useful default.
VII The right amount of technology is the minimum needed to solve the problem Remove features and sensors that do not serve the core job.
VIII Technology should respect social norms Introduce new behaviour gradually, especially cameras and microphones.
Principles verbatim from calmtech.com (“Developed by Amber Case”). Case created the principles and the site in 2014 (Calm Tech Institute).

Two of Case’s sub-points sum up the spirit. Under principle III: “A calm technology will move easily from the periphery of our attention, to the center, and back.” Under principle IV: “Machines shouldn’t act like humans. Humans shouldn’t act like machines. Amplify the best part of each” (calmtech.com).

A kettle tells you the water is ready without pulling you out of your book. That idea runs through all twelve examples below.

312 calm technology examples

The clearest calm technology examples range from a 1995 string that twitched with network traffic to a tea kettle, a glowing stock orb, the Apple Watch’s taptic alerts, iOS Focus, e-ink readers and the first Calm Tech Certified products. Each informs without demanding attention, and most use light, sound, touch or position instead of a screen.

1. The Dangling String (1995)

Artist Natalie Jeremijenko’s “Dangling String” was “an 8 foot piece of plastic spaghetti” hanging from a motor in the ceiling at Xerox PARC, connected to the office network. Busy traffic made it whirl; a quiet network made it twitch (Weiser & Brown). Her own title for the work was Live Wire (McCray).

2. The inner office window

Weiser and Brown also pointed to glass windows between offices: you see who is around and whether they look busy, without anyone sending a message (Weiser & Brown).

3. The tea kettle

Case’s canonical example: “A tea kettle can be set and forgotten, until it sings. It does not draw constant attention to itself until necessary” (calmtech.com).

4. Roomba status tones

Case cites the Roomba’s short tones, which communicate status without speech or a screen (calmtech.com). The airplane lavatory “occupied” sign is another of her examples.

5. Headphones that pause the music

Case describes it as a calm communication pattern: “when the headphones of an iPhone become disconnected, the music player automatically pauses the music” (calmtech.com).

6. The Ambient Orb (around 2002)

Ambient Devices’ glass orb glowed “deep red when the Dow Jones Industrial Average is headed down, shading to bright green when it is surging,” according to The New York Times in 2003 (NYT via UMass Lowell).

7. Apple Watch taptic alerts (2014)

Apple introduced the Taptic Engine in 2014 to “discreetly enable an entirely new vocabulary of alerts and notifications” (Apple Newsroom). A tap on the wrist is private and peripheral.

8. iOS Focus and notification summary (2021)

iOS 15 added Focus, “filtering notifications based on what a user wants to focus on in that moment,” and a notification summary delivered “at scheduled times determined by the user.” Your Focus status can also tell contacts you are not available (Apple Newsroom).

9. Android Digital Wellbeing (2018)

Android 9 Pie shipped Digital Wellbeing tools in August 2018, including a usage dashboard, app timers and a wind-down mode (BBC).

10. A thermostat you read from across the room

Nest’s Farsight screen shows the time or temperature in large type. On the fourth-generation thermostat it “automatically wakes up” when there is activity about 3 metres away (Google support).

11. Sunrise lights and e-ink

Philips Hue’s wake-up automation “slowly brightens your bedroom over a set interval to mimic sunrise” (Philips Hue). E-ink readers such as Kindle use a paper-like, glare-free screen (Amazon), and Light Phones are “designed to be used as little as possible” (Light).

12. Calm Tech Certified products (2024–2026)

The reMarkable Paper Pro earned Calm Tech certification in December 2024 (reMarkable). The Institute lists the Modos Flow paper-like monitor and Airthings Renew at its top Platinum level (Calm Tech Institute), and in September 2026 certified the Invisible Display, a 7.5-inch e-ink calendar in a wooden frame (Calm Tech Institute).

4What is Calm Tech Certified?

Calm Tech Certified is a product certification run by the Calm Tech Institute, which Amber Case launched in May 2024. Products are scored on an 81-point specification across six areas: attention, periphery, durability, light, sound and materials. Levels run from Certified to Gold and Platinum, with a Pre-Certified label for products not yet released.

Office workers are interrupted every two minutes, the research below shows. Several popular attention statistics, however, turn out to be myths.

5How much attention do our devices take?

A lot, but many popular statistics are wrong. Verified research shows adults handled 63.5 notifications a day in a 2014 study, half of teens get 237 or more a day, and office workers are interrupted every two minutes. The “8-second attention span” and “23 minutes lost per interruption” claims are misquotes or myths.

Minutes and seconds before interrupted work was resumed, on average, in Gloria Mark’s research. It is often misquoted as “every interruption costs 23 minutes.” In the same research, 81.9% of interrupted work was resumed the same day.
Gallup Business Journal interview with Gloria Mark, 2006

Mark’s lab work adds a twist. In a CHI 2008 study of 48 people, those who were interrupted finished tasks faster “with no difference in quality,” but they paid for it in “more stress, higher frustration, time pressure and effort” (Mark, Gudith & Klocke, CHI 2008). The cost of interruption is less about lost minutes and more about strain.

Myth
“Our attention span is now 8 seconds, shorter than a goldfish.” The BBC traced this figure: it did not come from Microsoft’s own research, and goldfish do not have short memories either.
BBC News, 2017

Email remains a large share of the load. McKinsey estimated in 2012 that interaction workers spend about 28% of the workweek managing email (McKinsey), and Microsoft’s 2025 data puts the average at 117 emails a day (Microsoft).

What people say about notification overload

Reddit’s calm-tech conversations are less about “too much technology” and more about obligations that never end. The top thread in r/digitalminimalism on this theme, with 261 upvotes, is about texting, not apps. Skepticism shows up too: a 2025 thread asked what people think of Calm Tech certification, and reMarkable owners questioned “distraction-free” devices that push cloud upsells.

“Lately, I’ve noticed how draining texting can be. It’s not just the constant notifications, but the unspoken pressure to respond quickly or keep conversations going.”

r/digitalminimalism, December 2024

“Text convos are unbelievably draining! Like an ongoing task that is never accomplished.”

r/digitalminimalism, December 2024

“Without involving features, you can’t say your device is distraction free when it continuously pop up alerts pushing you to subscribe to their cloud system.”

r/RemarkableTablet, December 2025

“I’ve tried deleting apps, but I always end up reinstalling them.”

r/nosurf, July 2025

From a soft light to an alarm bell: Apple’s four interruption levels give every notification its place.

6How do you design calm notifications?

Sort every notification by urgency before you send it. Apple’s design guidelines define four interruption levels: Passive, Active, Time Sensitive and Critical, and warn never to use Time Sensitive for marketing. Most messages belong in a summary or a passive status, not an alert that breaks through Focus.
Level (Apple) Use it for Calm alternative
Passive Information the user can read later Deliver in the notification summary
Active The default for relevant updates Batch similar updates into one
Time Sensitive Something that needs action now, for the user Never for marketing
Critical Health, safety and security emergencies Reserve for real emergencies only
Levels from Apple Human Interface Guidelines: Managing notifications. “Calm alternative” column is design advice.

Rules also push in this direction. Article 25 of the EU Digital Services Act says platforms “shall not design, organise or operate their online interfaces in a way that deceives or manipulates” users (DSA Art. 25). The UK’s children’s code has a standard on nudge techniques (ICO).

Calm copy: instead of, use

Instead of Use
“Are you sure you want to delete this?” on every delete Delete immediately and offer “Undo” for a few seconds
“URGENT: Your password expires soon!” “Your password expires in 7 days. Change it now or later.”
A pop-up for every new message A badge or a quiet summary at a time the user chooses
“Device offline!” alarm “Offline since 9:14. Still running your last schedule.”

7Calm technology audit: score your product

Rate your product against each of the eight calm technology principles. The audit gives a score out of 100, shows your weakest principles and suggests one concrete fix for each. Use it in a design review or before launching a new notification, sensor or feature.

8Common calm design mistakes

The most common mistakes are confusing minimalism with calm, hiding important state, using “urgent” channels for routine messages, and failing badly when the network drops. A calm product is not an empty one: it shows the right information at the edge of attention and fails gracefully.
  1. Minimal is not calm. Removing information can force people to open the app to check status, which costs more attention.
  2. Calm must not become invisible. If something important changes, it has to reach the center of attention. The kettle still whistles.
  3. Escalation abuse. Using alerts or Time Sensitive notifications for promotions trains people to ignore all of them.
  4. No offline mode. Principle VI: the product should keep working, or fail in a predictable way, without a connection.
  5. Tiny targets. Calm also means easy to use: Apple’s default touch target is 44 × 44 pt (Apple HIG), and WCAG 2.2 sets a 24 × 24 CSS pixel minimum (W3C).

Frequently asked questions

Who invented calm technology?

Mark Weiser and John Seely Brown of Xerox PARC described calm technology in “Designing Calm Technology,” dated December 21, 1995. Amber Case later wrote the eight principles used today. Sources: calmtech.com, O’Reilly.

What are the 8 principles of calm technology?

Require the smallest possible amount of attention; inform and create calm; make use of the periphery; amplify the best of technology and humanity; communicate without needing to speak; work even when it fails; use the minimum technology needed; and respect social norms. Source: calmtech.com.

What is an example of calm technology?

A tea kettle that only whistles when the water boils is the classic example. Modern ones include Apple Watch taptic alerts, iOS Focus and notification summaries, e-ink devices, and Calm Tech Certified products such as the reMarkable Paper Pro. Sources: calmtech.com, reMarkable.

What is the difference between calm technology and ambient computing?

Calm technology is about how much attention a technology asks for. Ambient computing is about technology spread through rooms, cars and cities that acts on context. Ambient systems can be calm or very intrusive.

Is our attention span really 8 seconds?

No. The BBC found that the 8-second figure did not come from Microsoft’s research. Gloria Mark’s measurements show people focus on one screen for about 47 seconds on average before switching. Sources: BBC, APA.

What is Calm Tech Certified?

A certification by the Calm Tech Institute that scores products on an 81-point specification across attention, periphery, durability, light, sound and materials, with Certified, Gold and Platinum levels. Source: Calm Tech Institute.
