Motion capture for artists using AI apps
No full textMotion capture based on Artificial Intelligence (AI) represents a significant advancement in the capture and manipulation of human motion, providing a more accessible approach to generate lifelike animations. Traditionally, motion capture has been employed to produce realistic character movements for film and video games. However, its applications extend beyond figurative representation, enabling the mapping of motion onto diverse visual forms in various contexts, such as artistic installations and live performances. Traditional motion capture systems are costly, limiting accessibility for artists. AI-driven motion capture has democratized this technology, enabling innovative and abstract visual explorations. A key question arises: do AI-based motion capture tools produce meaningful results in diverse artistic contexts? This paper compares low-cost AI motion capture solutions, to evaluate their potential for artistic applications, through quantitative and qualitative analyses. Motion capture data from these AI solutions were used to generate abstract and non-representational visual interpretations
Prospective workflows for generative AI-assisted immersive illustration: the case of multiplicity
No full textThe introduction of generative AI into the field of immersive illustration threatens to displace both the knowledge of perspective and the practice of drawing as the main tools of this very technical branch of illustration. Yet for many illustrators this type of technical drawing is not just a tool but an end in itself. We consider what future workflows may accommodate both AI and handmade drawing in a way compatible with the market realities of illustration, and we illustrate our reflections with the case study of MultipliCity, an installation exploring and representing the interplay between myth and reality in the Venetian urban environment
The hidden logic of film art
No full textThis audiovisual essay extends Rudolf Arnheim’s seminal work on the psychological significance of visual form into the realm of moving images. While Arnheim’s Art and Visual Perception (1954) applied Gestalt principles to static artworks, his analytical tools were less adaptable to film, where movement, editing, and shifting perspectives complicate static visual analysis. Leveraging the dynamic potential of the audiovisual essay format, this project introduces keyframe animation as a method to visualize and analyze formal patterns in cinema. Focusing on the seduction scene in Stanley Kubrick’s Barry Lyndon (1975), the essay overlays abstract animations based on cognitive primitives—such as containers, objects, and paths—to trace the evolving visual rhythm of the scene. These animations reveal shifts in framing, character positioning, and spatial dynamics that convey the emotional trajectory of Lady Lyndon’s seduction. By highlighting how perceptual forms—independent of narrative context—generate meaning, the essay offers a novel, cognitively informed approach to film analysis. It not only builds on Arnheim’s insights into the unity of form and content but also demonstrates how digital tools can uncover the hidden structures that shape our experience of film
A commentary on "The hidden logic of film art" as audiovisual criticism
Full text linkOver the course of a long career, Rudolf Arnheim applied the principles of gestalt psychology to the study of art. One of his signature techniques was the use of schematic diagrams to illustrate the underlying structure of paintings and other artworks. Although Arnheim wrote extensively about cinema, he never applied his schematic diagrams to film examples. The audiovisual essay The Hidden Logic of Film Art addresses this gap, using animated diagrams to illustrate the underlying structure of a scene from Barry Lyndon (1975). This commentary situates The Hidden Logic of Film Art within a larger history of audiovisual criticism, where schematic diagrams have long been used to explain the nuances of film form

Full text linkInteligência Artificial - ameaça ou recurso para os enfermeiros?
Full text linkArtificial Intelligence is a reality and its integration into Nursing care will grow exponentially in the coming years, although Nursing will continue to be a place of compassionate care, touch and close relationships. The way in which it will be integrated is extremely important for practice, so it is necessary to understand this phenomenon and how it is felt by nurses. This study aims to: analyze nurses\u27 perceptions about the integration of Artificial Intelligence in Nursing care, identifying the benefits, implications, and ethical concerns associated with clinical practice. To this end, an integrative literature review was conducted, with the research being carried out through the EBSCOhost search engine across several databases, namely, Academic Search Complete, APA PsycInfo, Complementary Index, CINAHL, Directory of Open Access Journals, MEDLINE, Science Direct, and Supplemental Index.After analysis and respecting the previously established inclusion and exclusion criteria, 7 studies were identified, which highlight the contributions of AI in nursing care, revealing the potential expansion of its influence. However, ethical issues regarding its use are also raised, although to a lesser extent. Despite this study showing that AI is perceived as a benefit rather than a threat by nurses, this finding cannot be generalized due to the limitations of this study. Further similar and complementary studies, on a larger scale, will be necessary in order to gain a better understanding of the topic.A Inteligência Artificial é uma realidade e a sua integração nos cuidados de Enfermagem irá crescer exponencialmente nos próximos anos, apesar de a Enfermagem continuar a ser um lugar do cuidado compassivo, do toque e da relação de proximidade. A forma como será integrada, é de extrema importância para a prática, pelo que é necessário compreender este fenómeno e a forma como é sentido pelos enfermeiros. Este estudo tem como objetivo: analisar a percepção dos enfermeiros sobre a integração da Inteligência Artificial nos cuidados de Enfermagem, identificando os benefícios, implicações e preocupações éticas associadas à prática clínica. Para o efeito foi realizada uma revisão integrativa da literatura, tendo a pesquisa sido efetuada através do motor de busca EBSCOhost em diversas bases de dados, nomeadamente, Academic Search Complete, APA PsycInfo, Complementary Index, CINAHL, Directory of Open Access Journals, MEDLINE, Science Direct e Supplemental Index. Após análise e respeitando os critérios de inclusão e exclusão previamente estabelecidos, apuraram-se 7 estudos, que ressalvam os contributos da IA nos cuidados de enfermagem, revelando o potencial alargamento da sua influência. Contudo, são também levantadas questões éticas na sua utilização, embora, em menor escala. Apesar do presente estudo demonstrar que a IA é percecionada como um benefício, e não como ameaça pelos enfermeiros, esta constatação não pode ser generalizada, atendendo às limitações deste estudo. Será necessário a realização de outros estudos similares e complementares a este, em maior escala, de forma a obter um melhor entendimento acerca da temática
Life after Yodel’s case law: protecting digital platforms workers under criminal law?
Full text linkDigital platforms posed several concerns related to individuals’ labour rights. In fact, individuals performing services for digital platforms are frequently considered self-employees, due to the classical notion of ‘worker’ based on the degree of independence and subordination in the exercise of his/her activity. Although some progress was made through European and national legislation adopted in the last years, the legal protection of such individuals still requires reflection. In this context, Criminal Law could contribute to the protection against undeclared work. However, the protection of workers’ rights through criminal law cannot be considered adequate only to compensate for the lack of effectiveness of other social policies. In fact, there must be a need for intervention by criminal law, which, as we know, complies with the principle of subsidiarity or minimum intervention due to its impact on fundamental rights. To this extent, the role of European and national criminal law should be weighed with caution
The legal framework on freedom of association in the Italian armed forces and military police: exploring strengths and weaknesses
Full text linkThe paper explores the development of military trade unionism in Italy following the enactment of Law No. 46 of 28 April 2022. This legislation overturned the long-standing ban on freedom of association for the armed forces and military police, acknowledging the right of military personnel to establish and to join “military professional associations of a union nature”. The paper emphasses that Law No. 46/2022 does not recognise an absolute right to organise. Instead, it strikes a balance between the right to freedom of association, enshrined in Article 39(1) of the Constitution, and the duty of homeland defence, stated in Article 51(1) of the Constitution. Against this background, the paper examines the newly introduced rights, alongside the constraints involved, to highlight the features of the current model of military representation
The gradual denaturalization of confiscation in the European Union: between effectiveness and a departure from criminal law foundations
Full text linkThis paper explores the evolving legal framework of asset confiscation in the European Union, focusing on the systematic departure from its traditional foundations in criminal law. It traces the legislative development from extended confiscation, non-conviction-based confiscation, and third-party confiscation to the recently introduced confiscation of unexplained wealth under Directive 2024/1260. The analysis aims to demonstrate how a reform agenda driven by effectiveness has given rise to a strategic ambiguity surrounding the legal nature of confiscation. This, in turn, raises significant concerns regarding fundamental rights, legal coherence, and mutual trust among Member States, ultimately calling into question the legal certainty and rule-of-law compatibility of some aspects of the EU’s asset recovery policy.This paper explores the evolving legal framework of asset confiscation in the European Union, focusing on the systematic departure from its traditional foundations in criminal law.
