What is indoor tracking, and how does it help museums understand visitors?

Indoor tracking uses devices and software to work out which part of a building people are in, and how they move through it over time. For a museum, that means seeing how visits really unfold, rather than relying on observation or surveys alone.

Why GPS doesn't work indoors

GPS depends on satellite signals, which roofs, walls and the structure of a building weaken dramatically. Indoors, GPS positions become unreliable or disappear altogether — and GPS can't tell you which floor someone is on. Indoor systems therefore rely on signals or sensors installed within the space itself.

Common technologies

No single technology is best in every case. The right choice depends on the questions you want answered, the accuracy you need, your budget and the constraints of the building.

Bluetooth Low Energy (BLE) beacons

Small transmitters are placed around the space and an app on the visitor's phone detects which one it is close to. This works well for location-aware content such as audio guides, but only covers visitors who have installed the app and switched Bluetooth on.

Wi-Fi

Signals from Wi-Fi access points are used to estimate where devices are. You may be able to reuse some existing infrastructure, but accuracy is usually at the level of zones rather than individual exhibits, and modern phones that randomize their MAC addresses make counting people from Wi-Fi signals more complicated.

Ultra-Wideband (UWB)

Far more precise than the other options, which suits use cases that need fine-grained positions. It requires tags or compatible devices, and the cost per point is higher.

People counters and image analysis

These count people entering, leaving or occupying a zone, without visitors carrying anything. They are well suited to measuring density and total visitor numbers. If cameras are involved, privacy needs careful design — for example, processing on the device and keeping only counts that cannot identify anyone.

What museums can measure

• Visitors per zone — which galleries are busy and which are quiet
• Dwell time — whether visitors stop and look, or just walk through
• Visitor routes — whether most people follow the intended sequence, and where they double back or skip ahead
• Peak times — the days and hours when particular areas become crowded
• Reach — what share of all visitors actually make it to the exhibits further inside

Putting the data to work

Numbers only matter when they lead to decisions. Common uses include:

• Rethinking layout and sequence — moving key pieces to where more people pass, or fixing bottlenecks
• Staffing — adding people in busy zones and times, and fewer when it's quiet
• Evaluating temporary exhibitions — comparing interest across exhibitions using the same metrics
• Reporting to leadership and sponsors — backing up results and budget requests with verifiable figures
• Tuning audio guide content — matching the length of each track to how long visitors actually stay

Privacy to settle from day one

Collecting visitor data in Thailand must comply with the Personal Data Protection Act B.E. 2562 (2019), known as the PDPA. Approaches that reduce risk include designing the system to keep only aggregated, non-identifying data wherever possible, letting visitors know that data is being collected, asking for consent where needed — for example when an app is involved — and setting clear retention periods. The right details for your organization should be agreed with your legal team or data protection officer.

How to get started

1. Start with two or three questions you most want answered, such as “Why do so few people reach the second-floor gallery?”
2. Pilot in a small area — one floor or one gallery — to test the technology and the process before scaling up.
3. Capture a baseline before changing anything, so you can tell whether a new layout or new content really made a difference.
4. Decide who will use the data and how often. A good dashboard is designed around the people who actually use it.
