Beyond “us” and “them”

Hi there 👋  I’m PeO, a Professor of Design at Mid Sweden University exploring Accessibility, Usability and Universal Design.

We are all part of human variation. Every single I. Every single you. We all already belong. Nonclusive design starts from that and builds for it. Here you’ll find resources and writing about how design can meet variation with variation.

Nine of PeO's field photographs in round frames that bleed into each other and form patterns: a broad learning stair in an atrium. A red carpet laid over hotel entrance steps. A coffee cup beside a wheelchair placard. PeO photographing from his wheelchair in a museum. Smooth granite paving meeting cobblestones. A black toilet sign with braille. Four toilet pictograms on a red door. A curved concrete ramp in a historic square. And a portrait of PeO.

What nonclusion is

Nonclusion is a contribution to Universal Design,
not an alternative to it.

Universal Design targets how we can make things usable by as many people as possible. Nonclusion contributes a starting point for that work: we are all already part of human variation, so design can build for all of us from the start.

In practice, nonclusive design does three things. It designs for situations, where the interaction between people and environments is, rather than for groups of people. It lets signs and spaces communicate what they offer, rather than trying to pinpoint bodies, persons and roles. And it meets variation with variation: several kinds of seating, several ways to read, several ways to interact, several ways through a building.

Nonclusion is ultimately about societal development. It is a contribution within and to Universal Design. Design influences every day, in all situations, often without words. It tells people whether they are expected and whether they count as part of a norm or as deviating from it. Design that starts from human variation moves development processes beyond that sorting, one design decision, one entrance, one sign, one website at a time, beyond “us” and “them”. Most of this site explores what that looks like in practice.

Where to start

What brings you here?

Pick the situation nearest yours, and it will take you to the pages that describe how nonclusive design can support it. Everything you find along the way is free to use.

  • If you’re looking for good examples

    The most common question. Three guidelines gather good examples from streets, buildings, digital services and policy texts, photographed or quoted as we found them, ready to use in your own city or organisation.

    Start with the guidelines
  • If you’re designing something

    A product, a service, a building, a digital thing. Ask two questions of it: is it built as if I am already here, and does it express that I belong? The design moves and examples can give inspiration for how to do it.

    Start with the design moves
  • If you’re writing policy or requirements

    The sorting into “us” and “them” often happens in language first. Find where your text names groups of people, and try describing situations instead. Here you can find worked examples from real policy texts.

    Start with the text moves
  • If you teach

    Here you can find diagrams and one-pagers under CC BY 4.0, in English and Swedish, short essays that work as course reading, a photo workshop with a ready run sheet, and more.

    Start with the teaching material
  • If you want to try this with your team

    Field exercises you can run yourselves: a smartphone, some Velcro, a stretch of cobblestones. Several come with a one-page run sheet to bring along.

    Start with a workshop
  • If you’re doing research

    Anchor papers with open access where the publisher allows it, the full publication list on the CV page, and a vocabulary you are welcome to cite, build on, and contribute to.

The newsletter

Short essays about design beyond “us” and “them”.

The newsletter is where I explore new themes, write short essays, and talk about our research. It is on LinkedIn, because of the conversation in the comments. Subscribe. Join in.

I am entering a covered passage into a restaurant courtyard in a heritage quarter in Malmö. A band of smooth stones is laid through the rough cobblestones, with a metal handrail along the ochre wall.

Design Can Protect and Support Dignity, But Not Create It

Every person has inherent worth and dignity simply by being born. It exists whether or not design acknowledges it. But every design decision can either recognise and support that existing dignity, or undermine and violate it.

I am outside, looking through a glass door. A sign says "Only exit for", plus a wheelchair and a baby sign. I wonder where the baby's parents go.

The Lazarus Door – What Inclusion Actually Is

I recently saw Wake Up Dead Man – A Knives Out Mystery. It was a good film, and one thing in particular stayed with me: the Lazarus door to the Wicks' mausoleum. It took me until the day after to figure out why I couldn't let go of that do…

A picnic table with a variety of seating options, with and without backrest, armrest, and seating cutouts. This way, it meets human variation with seating variation. No sign, no symbol, no announcement, no requirements to meet.

Spring Challenge – Can You Photograph Belonging?

It is springtime in Sweden, and we are starting to spend more time outside. I have a challenge for you. The next time you go for a walk, look at the spaces around you, and try to photograph belonging. And if you travel, you naturally pay m…

An entrance with a revolving door to the left and a straight door to the right. There is no wheelchair sign, but my wheelchair is reflected back at me in the glass of the straight door.

The Sign My Mind Added

I was presenting at a workshop on accessibility and universal design in museums. About twenty participants were in the room. I was in the middle of describing the entrance of the building where I had worked for years, the Ingvar Kamprad De…

Benchmarking Universal Design – Are We Looking in the Right Place?

Have you ever found yourself in a situation where you started to discuss how to evaluate Universal Design and ended up discussing ramps and other accessibility features? I have. Many times.

On Being Disablised – What 57 000 Media Articles Say About Society

I made this photo collage to capture a feeling: the experience of being "disablised."

Activities you can run yourself

Workshops & experiments you can run.

Some things are better done than read. These are field exercises from my own teaching and research: a phone recording what cobblestones do to a wheelchair, a photographic question about belonging, the workshop I run in every design class. Each comes with instructions, so you can run them with your class, your team, or on your own.

Key ideas

The ideas my work revolves around.

The ideas I keep coming back to. Together, they are how I think about design, categorisation, and belonging.

  1. 01

    Universal Design

    The field I work in: design that starts from human variation instead of adding accommodations afterwards.

  2. 02

    Nonclusion

    Design that starts from the fact that everyone already belongs.

  3. 03

    Categorisation

    How the sorting of people shapes (and limits) what gets designed.

  4. 04

    “Us” and “them”

    A way to see whether a design divides people or refrains from it.

  5. 05

    Benchmarking Universal Design

    What it would take to measure Universal Design.

All the key ideas

Papers to start with, if you want the longer version.

The full publications list lives on the CV page. Start with these: where nonclusion was first articulated, where the inclusion paradigm was critiqued, and where the Activity Diamond and the harmonised Accessibility, Usability and Universal Design model were laid out. Open access where the publisher allows it.

Hi, I’m PeO. 👋

I am Per-Olof Hedvall, PhD and Professor of Design at Mid Sweden University. I study categorisations of “us” and “them” in design and policy, and how accessibility, usability, and Universal Design can help us move beyond that sorting.
