The first of Jakob Nielsen’s ten usability heuristics is Visibility of System Status.
De eerste van Jakob Nielsen's 10 usability heuristieken is "zichtbaarheid van systeem status".
This heuristic refers to how well the state of a system is conveyed to its users.
Deze heuristiek verwijst naar hoe goed de status van een systeem aan de gebruiker wordt laten zien.
Systems should always keep users informed about what is going on, through appropriate
Systemen moeten altijd hun gebruikers geïnformeerd houden over wat er gebeurt,
feedback within a reasonable time.
door geschikte feedback binnen redelijke tijd.
Imagine waiting for an elevator: you press the call button, and expect it to light up
Stel je voor dat je op de lift wacht: je drukt op de knop, en verwacht dat het lampje gaat branden,
to reflect that the system knows you’re waiting and will send an elevator soon.
want zo geeft het systeem aan dat hij weet dat jij wacht, en dat de lift zo zal komen.
You might even be able to see what floor that elevator is currently at, so you can gauge
Misschien dat je zelfs kunt zien op welke verdieping de lift nu is,
how long you’ll need to wait.
zodat jij kunt inschatten hoelang je nog moet wachten.
That knowledge is power: open communication between the system and the user not only allows you to understand what is happening, but also empowers you to make decisions based on that information.
Die kennis is macht: Open communicatie tussen het systeem en de gebruiker helpt je niet alleen te begrijpen wat er gebeurt, maar geeft je ook de macht om beslissingen te maken aan de hand van die informatie.
Consider what information about a system the user needs to know,
Overweeg welke informatie over het systeem de gebruiker moet weten,
and present that to them in a timely manner.
en presenteer dat vlot naar hen.
This system status could be persistent — or always visible — like a battery life or Wi-Fi connection indicator; or it can be feedback that is only shown after the user has done something.
Die systeem status zou altijd zichtbaar ("persistent") kunnen zijn, zoals de batterij status, of de Wi-Fi indicator; of de feedback kan alleen weergegeven worden nadat de gebruiker iets doet.
Just like when pressing that elevator button, feedback is critical to let people know their
Net zoals op het liftknopje drukken, is het heel belangrijk om mensen te laten weten dat
interactions with a system were acknowledged and successful.
hun interacties met een systeem erkend zijn en succesvol waren.
On a website or app, we expect visual feedback when we click an element — which can be
Op een website of een app verwachten we visuele feedback wanneer we op een element drukken,
as simple as changing the button color and, where appropriate, displaying a progress indicator.
dit kan zo simpel zijn als de kleur van de knop veranderen, of — waar geschikt — een progressiebalk laten zien.
People should feel confident that their click was recognized, and that the system is now working on the request.
Mensen moet zich zelfverzekerd voelen dat hun actie erkend is, en dat het systeem bezig is met hun verzoek.
Understanding a system’s current state is all about allowing users to feel in control.
De gebruiker voelt alsof hij alles onder controle heeft, omdat hij de systeem status begrijpt.
That said, providing visibility into the system does NOT mean you need to tell the user absolutely
Met dat gezegd te hebben, zichtbaarheid voor de systeem status betekent NIET dat je de gebruiker
everything the system is doing!
alles moet vertellen wat het systeem doet!
Don’t provide system status updates if the user can’t do anything with that feedback anyway.
Geeft geen updates over de systeem status als de gebruiker toch niets met die informatie kan.

behulpzaam zijn voor de gebruiker, of hem gerust stelt.
The Visibility of System Status heuristic highlights the importance of open and continuous
De "zichtbaarheid van systeem status" heuristiek benadrukt het belang van open en continue communicatie.
communication, which is fundamental to ALL relationships, whether with people or with our devices.
Dat is fundamenteel in ALLE relaties: met mensen, en met apparaten.
It’s the key to making a system feel reliable and predictable, which in turn creates trust.
Het is de sleutel om een systeem betrouwbaar en voorspelbaar te doen aanvoelen, wat vertrouwen creëert.
