The speech will cover the results of over three years of our studies, which resulted in a UX estimation method with precision over 82% with actual user data gathered from hundreds of users. Our solution in based on image analysis and processing of level walk-through or gameplay. Currently, the only way to verify the design of a virtual environment are tested with users, which due to the large time requirements and the number of participants needed are very expensive. For this reason, these tests are usually carried out at the production stage, where each change is also costly. Our method is a direct solution to this problem and can be used regardless of the technology and the video / VR game engine used, as well as at all stages of virtual space production. The feasibility of the project has been confirmed in our previous research (published in highly rated scientific journals) showing the effectiveness of the use of image analysis to estimate the user experience of virtual space.
