Trójwymiarowe modele i mapy bez gogli VR. Nowy ekran Sony zmienia pracę inżynierów

Praca z chmurami punktów, cyfrowymi bliźniakami miast i zaawansowanymi danymi przestrzennymi na płaskim ekranie często przypomina ocenianie rzeźby na podstawie fotografii – brakuje w tym kluczowego elementu głębi.

Branża technologiczna od lat szukała alternatywy dla niewygodnych gogli VR, a rozwiązaniem okazują się monitory nowej generacji. Urządzenia takie jak Sony Spatial Reality Display wprowadzają trójwymiarowy obraz bezpośrednio na biurka geodetów, architektów i planistów przestrzennych.

Jak działa holograficzny efekt bez okularów?

Wyświetlanie wiarygodnego obrazu 3D bez konieczności zakładania jakichkolwiek akcesoriów na głowę to wynik połączenia zaawansowanej optyki i technologii śledzenia wzroku (eye-trackingu). Monitor Sony Spatial Reality Display wykorzystuje wbudowany czujnik wizyjny, który w czasie rzeczywistym monitoruje pozycję źrenic użytkownika w trzech osiach (poziomej, pionowej i w głąb).

Sony ELF-SR2 to przyszłość, którą widzieliśmy na własne oczy. Ten monitor 3D nie potrzebuje okularów

Dzięki precyzyjnym informacjom o tym, skąd dokładnie patrzy obserwator, oprogramowanie generuje dwa niezależne widoki sceny. Nałożony na panel LCD specjalny układ mikrosoczewek precyzyjnie rozdziela światło, kierując odrębny obraz do lewego i prawego oka. Efekt? Gdy użytkownik porusza głową, perspektywa wyświetlanego obiektu zmienia się płynnie i naturalnie, dokładnie tak, jak przy oglądaniu fizycznej makiety. Całość wyświetlana jest w rozdzielczości 4K przy zachowaniu szerokiej palety barw przestrzeni Adobe RGB.

Cyfrowe bliźniaki i infrastruktura pod pełną kontrolą

Technologia ta znalazła swoje praktyczne zastosowanie w szeroko pojętej geoinformatyce. Została ona zaprezentowana profesjonalistom podczas V Akademii Kartografii i Geoinformatyki we Wrocławiu, pokazując, jak eliminuje ograniczenia tradycyjnych ekranów 2D.

Dla inżynierów i urbanistów to potężne narzędzie do analizy modeli BIM (Building Information Modeling) oraz tak zwanych cyfrowych bliźniaków (Digital Twin). Połączenie trójwymiarowej bryły budynku z płynącymi na żywo danymi z czujników (np. o zużyciu energii czy temperaturze) na ekranie przestrzennym ułatwia wczesne wykrywanie kolizji w projektach instalacji. Pozwala to na szybsze wprowadzanie poprawek jeszcze przed wylaniem pierwszych fundamentów. Z kolei geodeci zyskują znacznie bardziej przejrzyste środowisko do wizualnej kontroli skomplikowanych modeli fotogrametrycznych i chmur punktów.

Koniec z drogimi makietami fizycznymi

Wdrożenie ekranów przestrzennych rozwiązuje jeszcze jeden istotny problem biznesowy: komunikację na linii projektant-inwestor. Złożone zjawiska przestrzenne, symulacje środowiskowe czy plany zagospodarowania terenu są trudne do zinterpretowania dla osób bez wykształcenia technicznego.

Możliwość „zajrzenia” do wnętrza projektowanej infrastruktury bez zakładania gogli ułatwia konsultacje społeczne i prezentacje dla zarządów miast. W administracji publicznej i zarządzaniu kryzysowym taka forma wizualizacji pozwala na błyskawiczną i bezbłędną ocenę sytuacji topograficznej. Przyspiesza to procesy decyzyjne i znacząco redukuje koszty, eliminując potrzebę budowania czasochłonnych i drogich, fizycznych prototypów i makiet.

The amygdala plays a crucial role in emotional processing, particularly in detecting threat-related stimuli and regulating responses to them. Fear processing is a vital function emerging during the latter half of the first postnatal year and becomes progressively more regulated and context-dependent with maturation across early childhood. However, the neural underpinnings of early-emerging individual differences in fear processing remain underexplored.

In our previous studies, we have examined how 8-month-old infants avert their gaze from fearful faces relative to non-fearful faces. In general, children of this age tend to stay looking at fearful faces more easily, a phenomenon called fear bias. However, in our previous study, we found that a smaller left amygdala volume after birth was associated with a greater likelihood of averting gaze from fearful faces at 8 months of age.

Our latest study builds on this by extending the analysis longitudinally. We investigated whether neonatal amygdala volume and microstructural properties, indexed by mean diffusivity, are associated with attentional biases toward fearful faces at 30 and 60 months. Neonatal MRI was acquired at 2–8 weeks of age using 3T MRI. The same cohort completed eye-tracking at follow-ups (n = 57 at 30 months; n = 54 at 60 months).

Our results show that larger newborn left amygdala volume was associated with decreased disengagement from fearful (vs. non-fearful) faces at 30 months (p = .041), but not at 60 months (p = .553). Moreover, sex-specific analyses indicated that higher mean diffusivity in the left amygdala was associated with lower fear bias at 60 months in boys (p = .046).

These findings highlight the dynamic nature of amygdala-related fear processing across early development. Associations between neonatal amygdala characteristics and fear bias appeared age-dependent and sex-specific, consistent with developmental changes in fear processing, with fear bias typically elevated in infancy and becoming less pronounced by around five years of age.

In our latest study, we examined how Finnish children read and integrate information across multiple expository texts when given an inquiry task. We were interested in how task-relevance of text information affects readers' eye movements and whether the eye movements are connected to the quality of an essay written after reading. We were also interested in differentiating between the effects of technical reading skill and reading comprehension in respect to these processes.

In total, 24 fifth and sixth grade Finnish native-speakers completed the experiment. Prior to testing, the participants were told that at the end of the testing session, they would have to complete an inquiry task (e.g., “What's the difference between human and dog hearing?”). During an eye tracking experiment, the participants read two science texts on the topic of the inquiry task. The texts contained both task-relevant and task-irrelevant text segments. After the reading task, the children wrote an essay to complete the inquiry task. Furthermore, participants' technical reading skill and reading comprehension were measured with an independent classroom test.

It was shown that the task-relevant segments were read longer than the task-irrelevant segments during first-pass reading. Moreover, reading skills modulated the effect of relevance, as weaker comprehenders were less likely to regress within an irrelevant segment. Furthermore, the relevance effect was more pronounced for the better technical readers with respect to look-backs. No reliable effects were found for the essay-writing task.

The results imply that the participants were able to detect which parts of the text were relevant and adjusted their reading accordingly, based on their reading skills. However, they did not seem to form a coherent memory representation of the relevant text contents in order to perform well in the essay writing task.

Understanding verbal irony involves detecting that the speaker’s intended meaning contrasts with the literal meaning. This is challenging for children as the underlying skills required to understand irony may not be fully developed.

In our new study, we investigated how 10-year-olds’ working memory, empathy skills, and gender were related to their processing and comprehension of written irony. Data from two previous eye-tracking experiments with 97 children (46 girls and 51 boys) were analysed.

Results showed that children with stronger empathy skills had higher irony comprehension accuracy and were less likely to reread ironic phrases. Higher working memory was linked to faster processing of irony but did not lead to higher comprehension. Conversely, lower working memory was associated with more accurate irony comprehension. Child gender was not related to irony comprehension.

These results imply that working memory and emotional perspective-taking are important for children’s irony comprehension, underscoring theories that take individual differences into account.
