# Live data on screens: what earns its place

> A clock, the weather, a news line, a countdown to Saturday's event. Live data makes a screen feel current without anyone touching it, as long as each piece has a reason to be there.

## Why live data matters

The hardest thing about a screen isn't putting it up; it's keeping it current. A loop of images that never changes turns into wallpaper within a couple of weeks. People stop looking because they already know what's there.

Live data is one of the simplest ways to fix that. A clock is always right. The weather changes every few hours. A news line changes through the day. A countdown gets shorter. None of these needs anyone to sit down and make new content, yet each one gives the eye a reason to come back to the screen.

There's a second benefit: a screen that shows the right time and today's weather looks looked-after. People trust the rest of what's on it a little more.

## The live pieces, and where each one fits

Not every place needs every widget. Here's what each kind of live data is good for, and where it tends to work best.

- Clock and date: lobbies, waiting rooms, canteens, factory floors, anywhere people keep an eye on the time. In a business with branches abroad or customers from other countries, a second clock in another time zone helps.
- Weather: entrances, hotel lobbies, municipal screens and cafés that sell hot and cold drinks. Today's forecast is what people actually want; a five-day outlook is a nice extra in a hotel.
- News feed or ticker: lobbies and waiting areas where people stand for a while. A single line of headlines is enough; full articles don't belong on a screen.
- Countdown: a sale ending on Sunday, a charity run, the start of a holiday, a new branch opening. A number that gets smaller every time someone looks creates a little urgency without shouting.
- Opening hours: shop doors and windows, clinics, public offices. They're the first thing people look for and the first thing to go out of date on a printed sign.
- QR code: anything people should do on their phones, such as booking, paying, leaving feedback or joining the Wi-Fi.
- A web page: a timetable, a production dashboard, a booking calendar or your own online menu, shown live so it's always as current as the source.

## When live data helps, and when it distracts

Live data should support the screen's main job, not compete with it. A menu board's job is to sell; a news ticker scrolling across the bottom of it pulls the eye away from the prices. A lobby screen's job is to welcome and inform; there, the same ticker is a good fit.

Ask one question of each piece: would someone standing here miss it if it were gone? If the answer is no, take it off.

- Helps: a clock in a waiting room, the weather at a hotel entrance, a countdown beside a campaign, opening hours on a door screen.
- Distracts: moving text over a price list, a news feed in a window people walk past in three seconds, several widgets all animating at once.
- Depends: a web page. A live departures board is excellent; a busy website designed for a phone, shown on a TV across a room, usually isn't.

> Give the main content most of the screen and keep live data to one corner or one edge. A small clock and today's weather in a corner do their job without taking over.

## Choosing sources you can trust

A live widget is only as good as what feeds it. A forecast that's wrong, a feed that stops updating or a headline from a source you wouldn't put your name to all reflect on you, because it's your screen.

- Weather should come from a reputable meteorological service, not a scraped website. Jonza's weather comes from an established meteorological source, so you don't have to pick one.
- For news, use the official feed (often RSS) of a publisher your customers would recognise. Prefer a feed focused on a topic that fits your place, such as local news for a municipality or industry news for an office.
- Check the publisher's terms before you show their headlines in public. Many allow it with attribution; some don't allow it at all.
- For web pages, show pages you or a partner control. If a third-party page changes its design or goes offline, your screen changes with it.

Also think about tone. A general news feed will, sooner or later, carry a headline about an accident or a tragedy. That may be fine in an office lobby and quite wrong above a children's menu. If that's a risk, choose a narrower feed or leave news out.

## Countdowns and campaigns

Countdowns deserve a mention of their own, because they turn an ordinary campaign into something people follow. "Sale ends in 3 days" is information; a number that's one smaller tomorrow is a reason to look again.

- Use them for real deadlines only. A countdown that resets every week stops being believed.
- Plan what replaces the countdown when it reaches zero. A screen stuck on "0 days" is worse than no countdown at all.
- Pair the countdown with the campaign's end date on the schedule, so the whole campaign leaves the screen on time, not just the number.

## Layering: live data over your own content

The best use of live data is often as a layer: a video or a set of product images playing as usual, with a clock, the weather or a ticker sitting on top in a fixed spot. The main content keeps changing; the live layer stays put and stays current.

Layering also saves work. Instead of baking the time or a price into a video and remaking it every time something changes, you keep the video as it is and change the text on top.

- Keep layers out of the area where the main content's important parts appear, such as faces and prices.
- Use the same corner on every screen, so people learn where to look.
- Match fonts and colours to your brand, so the layer looks like part of the design rather than something stuck on.

## The takeaway

Live data keeps a screen current without new work: a clock that's always right, the day's weather, a countdown that shrinks, opening hours that are never out of date. Use each piece where people will miss it if it's gone, take it from sources you'd stand behind, and keep it to a corner so your own content stays the star.

Jonza's live widgets, including the clock, weather, news feed, ticker, countdown, opening hours, QR code and web pages, sit over your videos and images and update on their own across every screen. If you'd like to see what fits your place, get in touch.

## Questions

### Does live data need someone to update it?

No. That's the point: the clock, weather, feeds and countdowns update on their own. You only set them up once.

### Can I show any news site on my screen?

Check the publisher's terms first. Many publish feeds that can be shown with attribution; some don't permit public display. Choose a feed whose topic and tone suit your place.

### Will a web page look right on a TV?

It depends on the page. Pages built to be read at a distance, like timetables and dashboards, work well. A website designed for phones usually needs a version made for the screen.

### Can different branches show their own city's weather?

Yes. The weather is set to a place, so each branch's screens can show the forecast for their own city.
