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.

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.

The imposition of excessive ship vibration induces corresponding motions and forces within the human body, possibly causing discomfort and degraded levels of comfort and health. The ISO criterion is designed to limit potential vibration to improve the crew comfort. Frequency weighting values are used to evaluate whole-body vibration in accordance with ISO standard. This study describes the frequency method used to compute the frequency weighted velocity values by using acceleration time signals. Firstly, the relationship between velocity and acceleration is deduced in detail, and then a time domain integrated method is proposed to calculate the frequency weighted velocity RMS, finally, the validity of the method is assessed on a real sea test experiment and compared with frequency domain method.
