The paper presents empirical evidence in how differently art history experts and non-experts scan images of architectural objects. The study is a work-in-progress on a ubiquitous system enhancing accessibility to architectural heritage for a broad audience with a special focus on the Blind and Visually Impaired (BVI). The system provides city navigation for BVI along with the location-based real-time information and Gaze-Led Audio Descriptions (GLAD) about architectural artefacts. Gaze visualizations of non-experts are used to guide professional audio describers in shaping more natural, gaze-led narratives.

Providing Computer Science (CS) students with a proper case study for Mobile App Programming and IT Project Management courses is challenging, especially when it should be focussed on the vital issues and differ every year. The authors as the research and didactic staff are involved in the multidisciplinary R&D project called Friendly City, which aims to promote the accessibility of architectural heritage to the blind and visually impaired (BVI) community by adding Audio Descriptions (AD) to 85 public places in Lodz (Poland). That is why the IT targets of the project were chosen as a case study in the mentioned courses. CS students as well as History of Art and Psychology ones with BVI or sighted beneficiaries play a crucial role during both courses. They will be working with the Lodz BVI Association to prepare their final project solution.

The paper contributes to scanpath bundling methods. We propose an analytical approach for statistical comparisons of aggregated scanpath visualizations by means of second-order gaze analysis metrics. The present study explores differences in attention distribution and cognitive processing over architectural objects between architects, art historians, and non-experts. The results show between-group differences in attention dynamics of the aggregated scanpaths. The aggregated scanpaths of both expert groups were focal, while non-experts' scanpaths were ambient. Experts also paid more attention to and tended to remember better the architectural details and their location. The discussion explores the scalability of the proposed approach for Human-Computer Interaction and accessibility technologies designed to enhance the experience of cultural heritage.

Teaching Computer Science (CS) students game development and cooperation with the clients is challenging. It demands to use the project ideas that are quite novel and can be used e.g. for the local society. It is also connected with using other subjects but it should stress soft-skills development, teamwork, and cooperation with the product owner. In the paper, we show the results of implementing in three courses that lasted altogether one year in a group of 18 CS students from mobile applications specialization. The students worked on four projects predefined during the online GGULIVRR event in 2020. After one year, they prepared in an Agile/ incremental way the projects that will be used by the city of Lodz (Poland) or in the company, etc.

The development of communication and other soft-skills among computer science students is not an easy task. Most curricula focus on technical skills. Team project methodologies are often used as a way to improve students? communication skills. However, the student teams are usually only comprised of computer science students. This paper is an experience report of the didactical methodology used in a project called [email protected], which has run annually since 2014. The project is short, intensive and team-based, with an important requirement that each student team is multinational and multidisciplinary. In the project, university lecturers act as mentors who help the student teams organize their work and tracks if a team?s planned didactical results are being achieved. The [email protected] project stimulates an increase of soft-skills among IT and other students who participate in the project. The detailed description of our process will allow others to recreate the project or build similar events in colleges or even company environments.

The paper presents statistical analysis of the enhanced SDEx method based on SHA-512 hash function. Statistical analysis of the method is performed in a similar way as for the method with the SHA-256, described in [9]. To realize it the ciphertext files were tested to check if they fulfill the conditions of pseudo-randomness. To test the pseudo-randomness of the encrypted files, a test package shared by NIST was used for this purpose. Additionally, compression tests on encrypted files were performed using the WinRAR software. The SDEx method based on SHA-512 hash function is faster and provides similar or higher level of security than AES with 256-bit key. The method can be used to secure end-to-end encryption in data transferring.

In the paper, the author provides a statistical analysis of the enhanced SDEx method based on SHA-256 hash function, which is used to secure end-to-end encryption in data transferring. To examine the quality of the enhanced SDEx encryption algorithm, the ciphertext files were tested to check if they fulfill the conditions of pseudo-randomness. To test the pseudo-randomness of the encrypted files, a test package shared by NIST was used for this purpose. In addition, compression tests on ciphertext files were performed using the WinRAR software.
