When advising from a distance, it is not only important to provide a well usable software for the customer, but also to design a meaningful consulting environment for the furniture consultant. In our previous study, we already conducted a trial with the transmission of the video image of the camera in the Microsoft HoloLens. Among other things, the study evaluated whether an egocentric or exocentric field of vision is best for the consultant.


In this study 4 different mechanisms of the representation of the living room of the customer for the advisor were tested in a played consultation. The goal is to bring the consultant "into" the client's home so that the consultant can make recommendations based on the client's environment. The tested mechanisms were:

  • 2D Video (The camera image of the HoloLens)
  • A reconstructed scene: the consultant's field of view is coupled with the customer's field of view (=the consultant cannot look around independently of the customer, as with 2D video)
  • A reconstructed scene: free movement of the field of vision for the consultant
  • A reconstructed scene: representation in Virtual Reality (consultant can look around freely and move in the 3D space via teleport)

The study was conducted with 9 consultants from our project partner Möbel Schulenburg. The questionnaires showed no significant differences between the mechanisms. In the interviews, however, the consultants mainly preferred the reconstructed scenes, and especially the scene with free field of view.

The paper with the description of the study is available here (or via ACM: https://dl.acm.org/doi/10.1145/3404983.3405520).

The study was presented at the Human and Computer 2020 Conference. Here is the video recording of the presentation (the four mechanisms are also shown there).)
