Status: in development (preview). The Event Guardian Visitor App is part of the Event Guardian system and is under active development. The functions described here show the planned feature set. For pilot projects and early access, get in touch.
The Event Guardian Visitor App connects visitors with the event’s digital situational picture. It offers practical functions for orientation, information and safety. At the same time it contributes — data-minimised and optionally anonymous — to measuring visitor flows, occupancy and waiting times.
No personal user account is required. The app can be activated directly for an event, for example via:
- a QR code on the ticket,
- a link from the organiser,
- a QR code at the entrance,
- the event website,
- public app stores.
Practical functions for visitors
The app accompanies the visitor before, during and after the event. Possible functions include:
- interactive site map
- personal event programme
- navigation to stages, halls and areas
- display of toilets and accessible facilities
- display of food and drink stands
- information about waiting times
- navigation to free entrances
- display of free parking areas
- public transport information
- weather warnings
- safety and conduct notices
- alerts about closed or overcrowded areas
- navigation via safe or accessible routes
- lost & found and loss reports
- direct reporting of defects and soiling
- emergency and help function
This turns the app into a personal companion throughout the event.
Anonymous support for live monitoring
With the visitor’s consent, the app can contribute anonymised data about the current event situation. This is not about the identity of individuals, but about aggregated information such as:
- number of visitors in an area
- directions of movement
- dwell time
- waiting times
- load on routes and entrances
- distribution of visitors across the site
- unusual crowd density
- use of particular facilities
Event Guardian can combine this information with further data sources — ticket scanners, counting sensors, camera systems, drones, Wi-Fi measurements, parking sensors and reports from event staff. This produces a more precise situational picture without having to record individual visitors by name.
Example: The app detects, anonymously, that more and more devices are moving towards an area that is already heavily loaded. Event Guardian can react early:
The area in front of the main stage is expected to reach its defined capacity limit within the next 15 minutes. Visitors should be guided to alternative areas via the app.
The app can inform affected visitors directly and show safe alternatives.
Help and emergency function with precise localisation
In an emergency, the visitor can request help via a clearly visible button. The report can include: precise position, area/zone/seat, type of emergency, number of people affected, a short description, a photo, a voice message, a callback or chat option, and the current movement of the reporting device.
Depending on the venue, the position can be determined from several sources: GPS, site and zone data, Bluetooth beacons, Wi-Fi-based positioning, QR codes at fixed locations, seat or block details, or a manually selected location. This way the control room receives not only the information that help is needed, but also the most precise location possible.
AI-assisted emergency report
A visitor can report an emergency with text, voice and photo — for example:
A person is lying on the ground and is unresponsive.
The AI assists with the structured assessment of the report. It can recognise visible cues in a photo (a person lying on the ground, visible bleeding, fire or smoke, a large crowd, a blocked rescue route, obvious hazards) and ask the reporting visitor simple follow-up questions: Is the person responsive? Are they breathing? Is there visible bleeding? Is there an immediate danger? How many people are affected?
From photo, description, answers, position and the current situational picture, Event Guardian compiles a structured report. The AI does not make a medical diagnosis. It supports the initial assessment and prioritisation for trained responders.
Automatic routing to the right response team
Through the Event CMDB and the live situational picture, Event Guardian knows the positions of the medical and security teams, their qualifications, current assignments and availability, routes and closed areas, visitor density, and available vehicles and resources. The system therefore determines not just the spatially nearest team, but the fastest available and professionally suitable team.
Example: A visitor reports an injured person in area B7. Event Guardian recognises that medical team 1 is closer but already on a call; medical team 2 is free and can reach the location via a lightly loaded route; and a security team nearby can secure the area. The platform suggests:
Dispatch medical team 2 to emergency location B7. Estimated arrival in three minutes. Bring in security team 4 to secure the area and guide visitors.
After confirmation, the assignment is transmitted directly to the teams’ mobile devices.
Direct communication with the reporting visitor
While the response team is on its way, Event Guardian can keep in contact: confirmation of receipt, an indication that help is on the way, follow-up questions from the control room, text or voice communication, further photos, an updated position, advice on securing the area, and simple first-aid notes.
Your report has been accepted. A medical team is on the way. If possible, stay with the injured person and keep the access route clear.
Medical instructions are provided only from pre-checked and approved first-aid content. The AI does not generate uncontrolled treatment recommendations.
Reporting defects and soiling
The same function can be used for non-medical incidents: broken toilets, missing toilet paper, soiled areas, overflowing waste bins, damaged barriers, failed lighting, water on walkways, broken sales or information systems, blocked access or dangerous objects. The report is supplemented by position and photo; the AI recognises the type of problem and routes it to the responsible team (cleaning, technical, sanitary service, security, event management, site or facility management).
Example: A visitor photographs a heavily soiled floor in the food area. Event Guardian recognises a possible slip hazard and automatically creates a prioritised task:
Liquid on the floor in food area North. Increased slip hazard at high visitor frequency. Cleaning team 3 is available and about 120 metres away.
Safety alerts directly to affected visitors
Event Guardian can send messages specifically to the visitors who are in a particular area or moving towards it — for example a severe-weather warning, an evacuation, a closed entrance, an overcrowded zone, a blocked route, a cancelled train connection, changed departure routes, a medical operation, a lost child, or general safety information. Instead of burdening all visitors with every message, the platform distributes information geographically and situationally.
The western exit is temporarily closed. Please use the north exit. The app will guide you along the shortest available route.
Intelligent evacuation and visitor guidance
In a critical situation, the app can be used for controlled visitor guidance. Event Guardian takes into account the visitor’s current position, the load on routes, closed areas, escape routes, the weather situation, available exits, the movement direction of other visitors, and information from the control room. This allows the app to guide different groups of visitors via different routes instead of sending everyone to the same exit. Final control and approval of such measures remains with the event or operations management.
Privacy and trust
The visitor app is developed according to the Privacy by Design principle. The principles are:
- use without a personal account
- no facial recognition
- no permanent identification of individual visitors
- anonymous or pseudonymous device session
- voluntary consent to location and sensor use
- transparent explanation of the data used
- separation of emergency data and general analytics data
- encrypted transmission
- limited retention periods
- automatic deletion of data no longer needed
- storage and operation on controllable infrastructure
For normal capacity measurements, data is aggregated as early as possible. During an active emergency report, more precise position and contact data may be processed as far as it is necessary to provide help.
The app as part of the Event Guardian system
The Visitor App is not an isolated add-on. It is directly connected to all relevant parts of Event Guardian:
Visitor app
↓
Position, report, photo or anonymised measurement
↓
AI-assisted analysis
↓
Event CMDB and digital situational picture
↓
Assessment of location, risk and responsibility
↓
Routing to medical, security, cleaning or technical teams
↓
Feedback and control
This way, every visitor voluntarily becomes an additional part of the shared situational picture — not as an identified person, but as an anonymous sensor, source of information and recipient of relevant alerts.
More safety and better service for everyone
For visitors: better orientation, up-to-date information, shorter waiting times, weather and safety warnings, easy problem reporting, fast help in an emergency, precise localisation, transparent feedback.
For organisers: a more precise situational picture, earlier detection of bottlenecks, additional measurement data, faster capture of defects, more efficient deployment control, better visitor communication, documented emergency and service processes, valuable experience data for future events.
For response teams: a precise deployment location, a structured report, photo and description, suitable routing, information about hazards and visitor density, clear prioritisation, digital feedback to the control room.
This turns a classic event app into an active part of safety, service and capacity management. Every visitor gets a digital companion — and the event management a more precise, faster and more complete situational picture.
