About this study:
Augmented Reality is a computer visualization modality that combines the visualization of the physical world with digital (virtual) elements. In this experiment, you will wear a Microsoft HoloLens 2 to experience some visualizations we are testing. This device is a special head-mounted glass that allows virtual objects to be displayed and experienced as holograms. In addition, the users can interact with the holograms by grabbing or pressing a virtual button with their fingers.
In our laboratory, we study how Augmented Reality can support outdoor applications such as navigation or urban interaction. This study aims to evaluate different visualization techniques to improve the perception of AR digital content placed outdoors. For that, we use the panoramic view of the TU-Wien Gusshaus rooftop to display the holograms. We would like to know where you perceive them.

Gußhausstraße 27/29
1040, Vienna
Procedure:
The experiment has the following phases:
- Introduction to the experimental area which is a reserved area in the TU-Wien Gusshaus rooftop and the panoramic view from Vienna.
- Introduction to Microsoft Hololens 2, how it works, how to interact, and a quick task to calibrate Hololens 2 for your eyes
- Run the experiment application, and execute a spatial calibration. Don’t worry about it, we will support you in this task.
- Collecting your perceptions: one by one, a digital landmark (long rectangular pink box) will be displayed in the direction of the panoramic view of the city of Vienna. Once you manage to visualize the digital landmark, you will evaluate where you perceive this digital landmark to be located and mark this location on a paper map. Then, you click on confirm to display the next digital landmark. You will be asked to assess the location of 9 digital landmarks in total
- After completing this task, you will be asked to fill out a short questionnaire where we will collect information such as age, gender, previous experience with Augmented Reality, and your sense of direction.
Duration:
20-30 minutes
Potential risks:
- If you had any prior seizure or epilepsy you CANNOT participate. According to the manufacturer (Microsoft), some people may experience a seizure when exposed to flashing lights or patterns in moving images or video games. Even people who have no history of seizures or epilepsy may have an undiagnosed condition that can cause “photosensitive seizures”. These seizures may have a variety of symptoms, including lightheadedness, altered vision, eye or face twitching, jerking or shaking of arms or legs, disorientation, confusion, or momentary loss of awareness. Immediately remove the device if you experience any of these symptoms and tell the experimenter
- If you have a pacemaker, you CANNOT participate: the manufacturer recommends a minimum separation be maintained between the device and a pacemaker to avoid potential interference with the pacemaker
- If you have a pre-existing binocular vision disorder, you CANNOT participate. The HoloLens can be worn over most glasses and used with contact lenses, but if you have a different pre-existing vision disorder, we recommend consulting a doctor before using HoloLens.
Privacy:
The data collected in this study are:
- Your responses to the questionnaires and demographics,
- Your markers on the paper map,
- Video record of your first-person view, and
- the audio recordings of your statements.
All collected data will be pseudonymized. In such form, it might be published in academic journals, presentations, or other media, but never in a way that would allow individual identification.
You can read more concerning the processing of your data in the Data Protection Declaration of the Department of Geodesy and Geoinformation of TU Wien. Provided here as a printed copy or online.
Benefits:
We will raffle 200€ among all participants who are not employees of the TU-Wien (approx. 50 people), for that, you need to provide your e-mail. Also, you will receive a small thank-you gift (Mini aluminum LED flashlight, or Carabiner Hooks Aluminium, and some very cool stickers)
Once again, thank you very much for your contribution to this research.
REMEMBER: You are free to stop and quit the study at any time during the study with no given reason or further consequences.
We can clarify any of your questions before the experiment or write us an email!
