Only with people they know, who are invited in person with a code. Pictures for every reply, read aloud if wanted. Anyone new waits in "Someone new" until they're accepted, and can be blocked quietly.
Every picture below is Haven itself, version 0.38, on a test computer with made-up things in it. First, how Home looks for different people; then each part of Haven in turn. Or try the set-up yourself.
The same computer, after different answers to the first-start questions. Every one of these is Haven's real Home screen; carers can change any of it later, and a "quiet day" or "sick day" lasts only for that day.













Home is a few big pictures: only the parts the person uses. Down the left edge is the Haven bar: Home, Back, Talk and Calm, always in the same place, on every screen.
The bar has a strip of its own. Websites, games and anything else open beside it, never over it, so Home and Calm can't be covered or lost.
Carers hold Home for three seconds to open the settings (with a PIN), so they're never in the person's way.

A picture plan of the day: what's happening now, and what comes next. A ring shows the time going, without numbers ticking.
Before something ends, a calm "time for…" warning comes as early as the person needs: minutes before, then again shortly before. The top of every screen says Now and Then.
Also: a First–Then board, a Timer that shrinks as time goes, and reminders.

A picture board that speaks, for people who don't talk, or for when talking stops. It uses AsTeRICS Grid, with Haven's own voice that works without the internet.
Quick phrases are one press away ("I can't talk right now", "Please write it down"), with a talking status to show others how talking is going today.
Symbols: ARASAAC pictograms by Sergio Palao, Government of Aragón (CC BY-NC-SA). Boards can use the person's own photos.
One press from anywhere. A slow breathing circle, quiet sounds, and the person's own "what helps me" (lie down, cold water, a favourite song).
Calm visits are never recorded or reported. Music that's playing gets quieter, and comes slowly back up afterwards.

The things a person loves, kept on shelves: a shelf for each interest, arranged the way they choose.
A heart on every website keeps anything they like, and it goes onto the right shelf by itself. An empty shelf offers to find some: videos, or pictures and facts.
If the person wants it, Haven AI can suggest where things go. It never moves anything a person placed themselves, and every move can be put back.

The person's websites as big pictures. Each person has the level that suits them: open with calm pause questions, filtered (safe search on, restricted YouTube), or only chosen websites.
Before buying something, typing a card number or giving an address, a calm question asks first. Flashing videos and pictures are softened or stopped on every website.

A carer chooses from a short list of free games and apps: learning games, a building game very like Minecraft, chess, painting. They download one after another, and each one opens full screen with a "Back to Haven" button.
Screen time can be limited, with a warning before it ends. Minecraft is there too, clearly marked as not free.

Only with people they know, who are invited in person with a code. Pictures for every reply, read aloud if wanted. Anyone new waits in "Someone new" until they're accepted, and can be blocked quietly.
Step-by-step guides with pictures or the person's own short videos: brushing teeth, making toast, anything.
A quick way to say how they are, in pictures. Shared with someone only if the person chooses.
Optional, and it runs on the computer itself. It explains what's on screen in plain words, helps with Haven, and does a few things from a fixed list, always asking first.
Calm versions of each: no adverts, no surprises, sound kept under the volume limit.
Big targets, dwell (rest on a button to press it), switch scanning, and a Calm key and help key on any big USB button.
A few questions at the start, then everything can be changed in the settings: what's on Home, colours, sounds, the day plan, websites, games, Messages.
The person sees what changed and who changed it. Adults who run their own computer say yes or no to every change.
Nothing installs by itself. Updates are signed by Haven, described in plain words, take effect at the next restart, and can be undone.
Backups to a USB stick or another computer at home, by themselves if wanted. Remote help only when someone at the computer starts it, with a banner while it's on.
