Artificial faces predict gaze allocation in complex dynamic scenes
2019
Both low-level physical saliency and social information, as presented by human heads or bodies, are known to drive gaze behavior in free-viewing tasks. Researchers have previously made use of a great variety of face stimuli, ranging from photographs of real humans to schematic faces, frequently without systematically differentiating between the two. In the current study, we used a Generalized Linear Mixed Model (GLMM) approach to investigate to what extent schematic artificial faces can predict gaze when they are presented alone or in competition with real human faces. Relative differences in predictive power became apparent, while GLMMs suggest substantial effects for real and artificial f…
A Navigation and Augmented Reality System for Visually Impaired People
2021
In recent years, we have assisted with an impressive advance in augmented reality systems and computer vision algorithms, based on image processing and artificial intelligence. Thanks to these technologies, mainstream smartphones are able to estimate their own motion in 3D space with high accuracy. In this paper, we exploit such technologies to support the autonomous mobility of people with visual disabilities, identifying pre-defined virtual paths and providing context information, reducing the distance between the digital and real worlds. In particular, we present ARIANNA+, an extension of ARIANNA, a system explicitly designed for visually impaired people for indoor and outdoor localizati…

Brain Source Correlates of Speech Perception and Reading Processes in Children With and Without Reading Difficulties
2022
Neural correlates in reading and speech processing have been addressed extensively in the literature. While reading skills and speech perception have been shown to be associated with each other, their relationship remains debatable. In this study, we investigated reading skills, speech perception, reading, and their correlates with brain source activity in auditory and visual modalities. We used high-density event-related potentials (ERPs), fixation-related potentials (FRPs), and the source reconstruction method. The analysis was conducted on 12–13-year-old schoolchildren who had different reading levels. Brain ERP source indices were computed from frequently repeated Finnish speech stimuli…
Pedagoģiskie risinājumi 5-6 gadu bērnu ar īpašām redzes vajadzībām matemātiskās kompetences attīstīšanai
2016
Šī pētījuma mērķis ir izpētīt, kāds būtu vispiemērotākais pedagoģiskais risinājums (pieeja un procesi), lai bērni vecumā no 5-6 gadiem ar īpašām vizuālajām vajadzībām iegūtu matemātisko kompetenci. Pētījumā tiek aplūkoti skaitļa jēdziena teorētiskie pamati un analizēti skaitļu mācīšanās posmi un to nozīmīgums šajā vecumā. Matemātiskā domāšana attīstās, bērnam nodarbojoties ar matemātiku. Matemātiskajā jomā domāšanas stingrība ir būtiska pazīme jau no pirmās mācīšanās pieredzes. Empīriskajā daļā tika izpētīta skaitļa jēdziena izpratne un matemātiskās domāšanas apguves procesi, anketējot bijušos studentus, kuri atsauca atmiņā savu matemātikas apguves procesu un tā tālākizmantošanu izglītības …
Aseemista okkultismia: Austin Osman Sparen maagiset monogrammit
2018
Austin Osman Spare (1886–1956) oli englantilainen okkultisti ja kuvataiteilija, joka kehitti uudenlaisen maagisen monogrammin luomisen tekniikan. Spare otti vaikutteita antiikista ja keskiajalta juontuvasta maagisten merkkien perinteestä, jonka keskeisiä tekstejä ovat olleet H. Cornelius Agrippan (1486–1535/1536) ja Giordiano Brunon (1548–1600) systemaattiset esitykset maagisista merkeistä. 1800-luvun lopun ja 1900-luvun alun Lontoossa Spareen puolestaan vaikuttivat uudet okkultistiset liikkeet, kuten Hermetic Order of the Golden Dawn, Ordo Templi Orientis ja Aleister Crowleyn (1875–1947) perustama Argentium Astrum. Myöhemmin Sparen tekniikkaa on hyödynnetty erityisesti 1970-luvulla luodun …
Recipient Design by Gestures : How Depictive Gestures Embody Actions in Cooking Instructions
2022
This paper investigates how depictive gestures, i.e., hand movements that depict actions, scenes or objects, are configured and used for accomplishing instructions. By drawing on video recordings of second language interactions in cooking classes for newcomers in Finland, we focus on instructions that project a certain type of complying bodily action as the relevant next action. We demonstrate that the instructions are designed to be sensitive not only to the contingencies of the material ecology of the kitchen but also to the epistemic and linguistic asymmetries between the participants. The analysis shows how depictive gestures contribute to the forward-feeding function of cooking instruc…

OnabotulinumtoxinA Modulates Visual Cortical Excitability in Chronic Migraine: Effects of 12-Week Treatment
2022
Chronic migraine is a burdensome disease presenting with episodic pain and several symptoms that may persist even among headache attacks. Multisensory integration is modified in migraine, as assessed by the level of the perception of sound-induced flash illusions, a simple paradigm reflecting changes in cortical excitability which reveals to be altered in migraineurs. OnabotulinumtoxinA is an effective preventive therapy for chronic migraineurs, reducing peripheral and central sensitization, and may influence cortical excitability. Patients affected by chronic migraine who started onabotulinumtoxinA preventive therapy were included. Clinical effects (headache diaries and migraine related qu…
Visual Literacy From the Perspective of the VTS Method
2017
The purpose of this article is to investigate visual literacy from the perspective of the VTS (Visual Thinking Strategies) method. The authors examine the viewpoints of seven American elementary school teachers on visual literacy and its meanings in the context of the VTS method. Data collection was done using a semi-structured questionnaire, which was followed by theory-driven content analysis. The authors emphasize that when supporting holistic development in a teaching context, it is the interconnected nature of aesthetics, growth and the learner’s learning which is more important than developing special skills, like visual literacy. In the teaching context visual literacy and language d…
