Before you start (1 minute)

Before the group arrives, just make sure you have these two things on your phone

• This link: www.nub.art/customer/login
• Your login details
• Recommended: A headset or a USB-microphone, especially if you plan to use the translation add-on. Try to find a unidirectional microphone, especially if the environment is noisy

Step 1 – Log in and open the group

• Open the link and log in.
• Once you're in, tap "Open group".

You've now created a group.
Nothing is happening yet — that's normal.

Step 2 – Give out the cards

Make sure each participant has one card.

Now ask the group to:

• Scan the QR code on their card with their smartphone.

If someone doesn't know how to scan a QR code, no problem:

• Ask them to go to nub.art
• Use the built-in scanner there
• (or they can type in the short code printed on the card)

Step 3 – Scan the cards (your part)

Now it's your turn.

• Tap "Open scanner" (1) on your screen.
• Quickly scan each participant's card.

Tip: If you prefer, you can even scan the cards before handing them out.

Step 4 – Check that everyone is connected

Tap "View participants" (6). You'll see a list:

• Each participant has a number.
• Next to each number, you'll see a small "traffic light".

Green means: all good.

If someone has a problem later, this number helps you identify them.

Step A – Activate the translation add-on

When you open a group, you'll be asked:

Enable Translation?

Tap Yes if you want live translation. Keep in mind that this is a paid feature and that we invoice based on usage time.

Tap No if you want a normal tour without translation.

Step B – Select your speaking language

Select the language you will be speaking during the tour. You will be able to change it if you decide to speak another language during the tour.

Step C – During the tour (guide view)

While the translation add-on is active, you will see a square on your screen showing:

• the selected speaking language (1)
• your translation usage time (2)

About the usage timer

• While you are unmuted and speaking (1), the timer is red and counts time
• When you mute (1), the timer:
  • turns black
  • stops counting
• The timer also stops when you close the group

Audio quality check: Below the spectrum display, you'll see a circular indicator showing the quality of the audio input (4).

• Green = good audio quality
• Yellow or red = poor audio quality

If the indicator turns yellow or red while you are speaking:

• check that you selected the correct speaking language
• reduce background noise
• move closer to your microphone

Speak normally, not loud. A calm, steady voice works best.

Step A – Open the media library

• Tap "Remote Control" (1).

A window opens on your screen showing all available content.

This window is only visible to you.

Step B – Send content to the group

• Tap the content you want to show.

The selected content appears immediately on all participants’ smartphones.

Participants do not need to click anything.

You can continue speaking while the content is displayed.

If you select another item, it replaces the previous one.

Button colors in the media library:

• Green: content has not been sent yet
• Grey: content has already been sent
• Red: content could not be delivered (e.g. due to poor connection)

If a button turns red, simply tap it again to resend the content.

To reset all buttons to green, tap "Restart tour" (2) (optional).

Step C – Close the media library

• Tap "Close" (3).

This closes the media library on your screen.

You can open it again at any time by tapping "Remote Control" (1).

What visitors experience

• The content appears automatically on their screen
• No interaction is required from them
• They can still mute/unmute and send questions as usual

You control what is shown and when it appears.

Good to know

• You can use the media library at any moment during the tour
• Only one content item is shown at a time
• The media library is prepared by our team based on your instructions
• You can have a different media library for each tour

Before your tour (recommended)

Test the system once beforehand.

If possible, test Nubart LIVE briefly before your tour. We provide free trial kits!

• Use the same smartphone you will use as a guide
• Test in conditions similar to the real tour
• Allow microphone access when your browser asks for it

A short test is usually enough to feel confident.

Check mobile coverage or Wi-Fi at your destination

Unlike traditional radio guide systems, Nubart LIVE uses the internet.

• Outdoors, this usually means mobile data
• Coverage can vary within a city

If the connection drops during the tour:

• simply move a few metres with your group
• the connection will recover automatically once coverage is available again

Use a modern smartphone for the guide

Even very old smartphones work well for participants.

However, the guide’s smartphone does a lot of work:

• audio processing
• live transmission
• optional live translation

For best results:

• use a relatively modern phone with a good processor
• make sure the battery is well charged before the tour

Audio setup in real tour conditions

Use a headset if possible

Urban environments or factories can be noisy.

Nubart LIVE works with the built-in microphone of your phone, but:

• a headset or external microphone improves sound quality
• if possible, use a unidirectional microphone, not omnidirectional
• it helps avoid background noise

This is especially useful in cities or in factories.

Avoid audio feedback if you use the translation add-on

The system is intentionally very sensitive.

For this reason:

• your microphone should not pick up voices other than your own
• translated speech from nearby devices should not be audible to your microphone

In practice:

• visitors should use headphones, or
• keep some distance between sending and receiving devices, or
• lower the volume of nearby phones

This is a physical audio issue, not a system malfunction.
