Empathy has become a central part of design and is loudly manifested in several frameworks such as universal design, inclusive design or human-centred design. This paper presents five independent Extended Reality (XR) scenarios that put potential users in the shoes of people with special needs such as vision impairments, autism spectrum disorder, mobility impairments, pregnancy state and some problems of the elderly. All exercises occur in a supermarket environment and the application is prepared for Oculus Quest 2 platform and is supported in some cases by tangible equipment (geriatric suit, pregnancy belly simulator, wheelchair). The proposed simulations were validated by experts who evaluated the quality of the proposed tasks and the possibility of simulating selected limitations or issues in XR. Ongoing development and testing of the XR application will provide further in-depth views on its usefulness, acceptance and impact in increasing empathy towards the challenges faced by the personas portrayed.

Nowadays, large amounts of unstructured data are available online. Such data often contain users' emotions and feelings about a variety of topics but their retrieval and selection on the basis of an emotional perspective are usually unfeasible through traditional search engines, which only rank web content according to its relevance with respect to a given search keyword. For this reason, in the present work we introduce the architecture of a novel emotion-aware search engine that can return search results ranked on the basis of seven human emotions. Using this system, users can benefit from a more advanced semantic search that also takes into account emotions. The system uses emotion recognition algorithms based on deep learning to extract emotion vectors from texts, images and videos and then populates an emotional index to allow users to visualise results related to given emotions. We also discuss and evaluate different deep learning models for building emotional indexes from texts, images and videos.

This work puts forth a new 4D hyperchaotic 2-scroll dynamics with a hidden attractor. The proposed nonlinear system has three quadratic terms and it is established that there is no fixed point for the proposed dynamics for all values of the system constants. Bifurcation analysis for the proposed system is investigated in detail. Next, we invoke Multisim for the development of an electronic circuit for the proposed hyperchaotic dynamics. Finally, we present some cryptographic applications of the proposed hyperchaotic dynamics. A new algorithm for the construction of substitution boxes (S-boxes) using the presented hyperchaotic system is proposed, in which the performance of the generated S-box demonstrates its efficiency and reliability for designing modern block-cipher cryptosystems. The proposed hyperchaotic system is utilised for generating Pseudo-Random Number Generators (PRNGs), in which the results of NIST SP 800-22 tests demonstrate the randomness characteristics of the generated PRNG sequences.
