Sometimes it feels that the reception rooms of the health care professionals are deliberately hidden. However, this is not intentional. The reason might be poor guidance or sudden changes in room arrangements etc. What would be the guidance system of your dreams from the car park to specialist´s tender care?



A hospital has many different functions every day. A lot of different facilities, examination equipment, professionals, and support services are needed to make services as good and versatile as possible for the customers. In addition, there is a diverse group of customers in the building with their special needs. All these factors together at the same time, in the same place, could easily cause confusion. However, we want to serve each customer as well as possible, which means that customers also needs an easy access to services.

On the other hand, can a customer experience be improved by allowing customers to get familiarized with the services in advance using a virtual model of the building? When designing hospital guidance, the normal accessibility and usability point of views, as well as the needs of special groups such as persons with different disabilities and sensory impairments, should be taken into account.

Approach and considerations

Totally new ideas and concepts for navigation in hospitals are more than welcome – possibly utilizing some of the latest technologies. These could be general concepts aimed for the average user or specialized concepts developed for specific hospital user groups. A goal might be to fill the gap between personal capacity and demands of the environment and increase person-environment-fit. If the solution is aimed for general public think about limitations of skills and available technology.


A 2D or 3D model could be used as the UI for mobile app. Unique QR codes can activate the app and guide you based on where you are.

Another way could be to use pattern recognition methods and artificial intelligence, like IBM Watson, and navigate in the hospital with this data. However, this approach is quite hard and could require lots of programming in a short time.

The new hospital buildings include a real indoor location system. An approach utilizing it would be optimal. However, it’s hard to build proof-of-concepts or prototypes before it is in place.


Technology, data, and materials

IFC and FBX models will be handed out on-site.

There are five HTC Vives and 10 Samsung VRs available for development, testing, and for some gaming.
