Dear Future Visitor,

How exciting that you would like to use a digital personal travel assistant and therefore participate in this study! To do this, we ask you to install two apps, WhatsApp and Sesamo, on your telephone. In addition, we will ask you to fill out a short daily questionnaire throughout your vacation. Below we provide a step-by-step guide to help you download the apps.

Step 1: Downloading WhatsApp

Most people already have WhatsApp on their telephone by default. If you do not already have it, go to the apps store on your phone, and search and download the app ‘WhatsApp’.

Step 1a: Add Zoey to your contacts list 

Add Zoey to your contact list with the following phone number:
+31 6 13482819. If you already have Zoey in your contact list, make sure you save the number with a recognizable name, for example, Zoey’s Tips.

Step 1b: Sign up for Zoey’s Tips

Open WhatsApp, search for Zoey and send the message ZOEY T ON. You are now signed up for the digital personal travel assistant. Zoey will contact you automatically.

Step 2: Download GPS-tracker

Sesamo (Mobidot B.V.) is a GPS-tracker, that keeps track of where you’ve been during your vacation. We ask you to download this travel app to help us gain insight into how visitors travel through the city. How do you download the GPS-tracker?

Step 2a: Download and Install

Download Sesamo (Mobidot B.V.) from the App Store (*click here*) or the Google Play Store (*click here*)

Step 2b: Sign up

After downloading the app, you can sign up using an activation code. The activation code for this experiment is: COPENHAGEN. From the login screen, go to “sign up”. Then enter your email address, username and a password of your choice. If the app asks, please turn on location and notifications. Rest assured, you will receive only one notification each day, containing a link to your daily questionnaire.

The app runs in the background and records your travel movements. As a participant, you can always pause the GPS tracker. Your travel behaviour will then not be recorded. Due to advanced technology, the power consumption of the app is minimal.

Step 3: Answering questions

We would like to hear about your experience during your vacation. Therefore, each night, you will receive a notification through the Sesamo app with a link to a short questionnaire. You’ll help us tremendously by filling out the questionnaire.

Final notice

  • Only we (Researchers Marion Sikkens, Bernadett Papp, and Dr. Ondrej Mitas) have access to this data. In addition to this, it is good to know:
  • The data will be separated from your name once we link it to your answers to the questionnaire.
  • Using the app will not drain your battery quickly, or lead to a sudden increase in data usage (consumption is less than 1mb per day).
  • It is important that you give the app permission to use your location data and allow notifications. Please always have your location services on for this app!
  • In the Sesamo app, in the ‘’support’’ menu, you can find the answers to frequently asked questions It also lists important settings for different devices. For further questions please contact, marion.sikkens@nhlstenden.com
