Figure–Ground Spatial Relationships in Finnish Sign Language Discourse
2020
AbstractThis study is about expressing spatial relationships between Figure and Ground in Finnish Sign Language discourse and shows that the variation in this expression is primarily discourse dependent. The main findings are, first, that Ground mainly precedes Figure whether the Figure is new or a known referent within the discourse; the reverse order is possible only when the Figure is known. Second, the lexical signolla(‘have’) appears more frequently in expressing spatial relationships with a new Figure and less frequently with a known Figure but never in a construction with Figure preceding Ground; the formoli(‘had’), referring to the past, appears only in Figure preceding Ground const…
When virtual and real worlds coexist: Visualization and visual system affect spatial performance in augmented reality
2021
New visualization approaches are being actively developed aiming to mitigate the effect of vergence-accommodation conflict in stereoscopic augmented reality; however, high interindividual variability in spatial performance makes it difficult to predict user gain. To address this issue, we investigated the effects of consistent and inconsistent binocular and focus cues on perceptual matching in the stereoscopic environment of augmented reality using a head-mounted display that was driven in multifocal and single focal plane modes. Participants matched the distance of a real object with images projected at three viewing distances, concordant with the display focal planes when driven in the mu…
Un sistema di relazioni: un “rizoma” narrativo per Cefalù
2022
Il saggio cerca di individuare, con tensione proiettiva, le relazioni significative fra architettura e luogo, e lo fa ripercorrendo il tema della strategia dei percorsi, affrontato negli ultimi decenni da più progettisti di Cefalù nei diversi interventi realizzati nel corpo della città compatta come già in quello della espansione più recente. Il caso di studio documenta le scelte di progetto esemplari di tre architetti siciliani – Pasquale Culotta (1939-2006), Giuseppe Bibi Leone (1936-2012) e Marcello Panzarella (1949) – che restituiscono la storia a noi contemporanea della “Scuola di Cefalù”. Le loro realizzazioni ci si svelano come epifanie del fare architettura; si tratta di opere capac…
Spazio e percorso in siciliano antico: analisi di un corpus
2020
In ancient Sicilian, basic spatial relations are encoded by means of prepositional phrases introduced by ‘da’ and ‘di’ (origin), ‘a’, ‘in’ and ‘intra’ (location and direction), ‘per/pir/pri’ (path). This contribution offers a description of these encoding means based on the examination of a corpus of Sicialian texts of the 14th to 16th centuries. The analysis is carried out against a cognitive grammar theoretical background and takes into account the existing studies on spatial relations in the world languages. These studies brought to light some recurring patterns: for instance, ‘direction’ tends to be encoded in a more articlulated way than ‘origin’, while the encoding of ‘path’ seems to …
ProteinScanAR - An Augmented Reality Web Application for High School Education in Biomolecular Life Sciences
2012
Understanding protein structures is a crucial step in creating molecular insight for researchers as well as students and pupils. The enormous scaling gap between an atomic point of view and objects in daily life hampers developing an intuitive relation between them. Especially for high school students, it can be difficult to understand the spatial relations of a protein structure. Due to lack of direct imaging techniques, molecules can only be explored by studying abstract molecular models. Here, the use of Augmented reality (AR) techniques has proven to strongly improve structural perception. In this work we present ProteinScanAR, an augmented reality framework for biomolecular education t…
External and internal facial features modulate processing of vertical but not horizontal spatial relations.
2019
Some years ago an asymmetry was reported for the inversion effect for horizontal (H) and vertical (V) relational face manipulations (Goffaux & Rossion, 2007). Subsequent research examined whether a specific disruption of long-range relations underlies the H/V inversion asymmetry (Sekunova & Barton, 2008). Here, we tested how detection of changes in interocular distance (H) and eye height (V) depends on cardinal internal features and external feature surround. Results replicated the H/V inversion asymmetry. Moreover, we found very different face cue dependencies for both change types. Performance and inversion effects did not depend on the presence of other face cues for detecting H changes.…
Three-Dimensional Classification of Lower Third Molars and Their Relationship to the Mandibular Canal.
2021
PURPOSE To develop a novel classification making full use of radiographic three-dimensional (3D) information to describe the position, geometric configuration of a mandibular third molar (M3M) and its spatial relation to neighboring structures such as the mandibular canal (MC). The classification presented in this study helps to establish a common language and serves as a framework for further studies, for example, on 3D parameters influencing prognosis of the M3M and level of difficulty associated with its removal. MATERIAL AND METHODS A total of 8 parameters were included in the classification including position, the cranio-caudal height, the number of roots of the M3M as well as its spat…
A Multi-scalar Approach to Long-Term Dynamics, Spatial Relations and Economic Networks of Roman Secondary Settlements in Italy and the Ombrone Valley…
2019
AbstractIn Roman landscapes, the particular sites defined as secondary settlements (also known as vici/villages, minor centres, agglomérations secondaires and/or stationes/mansiones) have played an ‘intermediary’ role between the cities and other rural structures (villae/farms), linked to medium- and long-distance economic and commercial trajectories. The aim of this paper is to apply a multi-scalar approach to model their long-term spatial relationships and connectivity with the Mediterranean exchange network. On the macro-scale, we have analysed a sample of 219 reviewed sites to understand the diachronic trends and spatial dynamics of attraction/proximity to significant elements of the la…
