    Virtual reality art and immersive experimental typography
    (İstanbul Aydın Üniversitesi, 2021-08-20) Uyan Dur, Banu İnanç
    As an emerging technology, Virtual Reality (VR) is perceived as a platform with the potential to changethe artwork generation methods and consumption paradigms The immersion, presence and interactionfeatures of VR provides for art unique opportunities to find new forms of expression. The potential ofVR in the artistic context will be revealed more clearly as researches in this area increase. The way artuses VR, how it interprets it, and the change VR will cause in art will expand the perspective for both.It is seen that in most of the researches on the relationship between VR and art, this relationship isconsidered in a general context. Very few researches has been done on the use of writing for artisticpurposes in VR and a limited number of practical studies have been produced. From this point of view,in this article, the relationship between experimental typography and VR art is examined with examples.The most effective use of writing in both a linguistic context and as a visual expression has been withinthe scope of conceptual art and this has brought new discourses and perspectives to the art. In thisregards, the inclusion of VR in the combination of writing and art may provide completely differentresults in conceptual and intellectual contexts. The intersection of writing, art and VR has a rich potentialfor different perspectives and new patterns. In this paper, the use of writing as the main narrative elementin VR Artworks has been discussed as an experimental typography study. Experimental typography isa practice based on exploration and interpretation, seeking new forms of visual expression apart fromtraditional patterns. VR Artworks based on experimental typography may reveal various contents thatexplore the role of language for art as structured images in virtual environment. Within this article, threeVR Artworks based on the experimental typography are examined and it has seen that they all presenteddifferent visual solutions than the clean, meticulous 3D visualization approach used in most VRapplications. In this context, it has been suggested that the use of experimental typography in VR Artcan expand the narrative language of VR.

    Background/Objectives: Glaucoma and Alzheimer’s disease (AD) are neurodegenerative conditions with vascular underpinnings. This study aimed to explore the relationship between blood pressure parameters such as mean arterial pressure (MAP), pulse pressure (PP), and cerebral perfusion pressure (CPP) and cognitive performance in patients with AD, normal-tension glaucoma (NTG), and healthy controls. We hypothesized that NTG patients, like those with mild cognitive impairment (MCI), may experience subtle cognitive changes related to vascular dysregulation. Methods: Ninety-eight participants (35 NTG, 17 AD, 46 controls) were assessed for CPP, MAP, OPP, and cognitive performance. Statistical analyses compared groups and examined correlations. Results: AD patients showed lower CPP and MAP (p < 0.001), indicating systemic vascular dysfunction, while NTG patients had higher ocular perfusion pressure (OPP) (p = 0.008), suggesting compensatory mechanisms. CPP correlated with visuospatial abilities in AD (r = 0.492, p = 0.045). MAP correlated with the Clock drawing test (CDT) scores in the NTG group (r = 0.378, p = 0.025). PP negatively correlated with cognition in AD (r = −0.527, p = 0.016 for CDT scores) and controls (r = −0.440, p = 0.002 for verbal fluency and r = −0.348, p = 0.019 for total ACE scores). Conclusions: The study highlights distinct hemodynamic profiles: systemic dysfunction in AD and localized dysregulation in NTG. These findings emphasize the role of vascular dysregulation in neurodegeneration, with implications for personalized treatment approaches targeting vascular health in neurodegenerative conditions.

    A novel approach to non-invasive intracranial pressure wave monitoring: a pilot healthy brain study
    (Multidisciplinary Digital Publishing Institute (MDPI), 2025-06-28) Karaliunas, Andrius; Bartusis, Laimonas; Krakauskaite, Solventa; Chaleckas, Edvinas; Deimantavicius, Mantas; Hamarat, Yasin; Petkus, Vytautas; Stulge, Toma; Ratkunas, Vytenis; Çelikkaya, Güven; Januleviciene, Ingrida; Ragauskas, Arminas
    Intracranial pressure (ICP) pulse wave morphology, including the ratios of the three characteristic peaks (P1, P2, and P3), offers valuable insights into intracranial dynamics and brain compliance. Traditional invasive methods for ICP pulse wave monitoring pose significant risks, highlighting the need for non-invasive alternatives. This pilot study investigates a novel non-invasive method for monitoring ICP pulse waves through closed eyelids, using a specially designed, liquid-filled, fully passive sensor system named ‘Archimedes 02’. To our knowledge, this is the first technological approach that enables the non-invasive monitoring of ICP pulse waveforms via closed eyelids. This study involved 10 healthy volunteers, aged 26–39 years, who underwent resting-state non-invasive ICP pulse wave monitoring sessions using the ‘Archimedes 02’ device while in the supine position. The recorded signals were processed to extract pulse waves and evaluate their morphological characteristics. The results indicated successful detection of pressure pulse waves, showing the expected three peaks (P1, P2, and P3) in all subjects. The calculated P2/P1 ratios were 0.762 (SD = ±0.229) for the left eye and 0.808 (SD = ±0.310) for the right eye, suggesting normal intracranial compliance across the cohort, despite variations observed in some individuals. Physiological tests—the Valsalva maneuver and the Queckenstedt test, both performed in the supine position—induced statistically significant increases in the P2/P1 and P3/P1 ratios, supporting the notion that non-invasively recorded pressure pulse waves, measured through closed eyelids, reflect intracranial volume and pressure dynamics. Additionally, a transient hypoemic/hyperemic response test performed in the upright position induced signal changes in pressure recordings from the ‘Archimedes 02’ sensor that were consistent with intact cerebral blood flow autoregulation, aligning with established physiological principles. These findings indicate that ICP pulse waves and their dynamic changes can be monitored non-invasively through closed eyelids, offering a potential method for brain monitoring in patients for whom invasive procedures are not feasible.

    Design fiction in design education: a case study on student projects
    (Sanat ve Dil Araştırmaları Enstitüsü, 2021-06-30) Uyan Dur, Banu İnanç
    Design fiction is a critical design approach which speculates on possible futures and forms technology-based visions on how future life might be and explains fictional worlds through the designed artefacts. Design fiction opens a free space to question current assumptions, operations, and systems. Design fiction is also used to create alternative worlds by moving away from various constraints, business expectations in particular, and to provide a convenient atmosphere for students to be able to think in a conceptual context, to develop new discourse, and to question their relation with reality. The present article argues that design fiction can be used as an instrument to question the position of design education in providing a labour force to the sector, and to move out of the structure of the design fiction that focuses on now and today. In this scope, the design fiction projects produced in the course of a Visual Communication Design Project will be examined, the methods used and the stages followed will be explained, and opinions will be presented on the possible angles of outcomes for students in design education.

    Consumer awareness and user experience in AR-enabled sustainable food packaging
    (Istanbul Medeniyet University, 2025-12-31) Köse, Ayşe Merve; Uyan Dur, Banu İnanç
    This article examines how augmented reality (AR) can serve the communication aims of sustainable food packaging. Scholarship on sustainability-oriented packaging and AR-mediated consumer communication is synthesized, and the design of a proof-of-concept AR application for an organic food package is presented. The prototype stages information through progressive disclosure, surfaces concise traceability cues and end-of-life guidance, and includes a lightweight game that frames pro-environmental actions. Design choices prioritize clarity, low cognitive load, and cross-device accessibility. To evaluate how the prototype was received by users, an exploratory, cross-sectional user study was conducted in which 31 adults interacted with the prototype on their own smartphones and then completed a brief questionnaire including one openended item; analyses were descriptive. Participants reported favorable perceptions of clarity, usability, information effectiveness, and visual quality. Most also reported higher knowledge and awareness and indicated intentions to apply what they learned. Thematic analysis converged with these patterns and identified priorities for improvement, including performance, accessibility, and audio balance. The article’s contribution is threefold, comprising a design-led articulation of ARenabled packaging for sustainability communication, a descriptive account of user responses at the proof-of-concept stage, and actionable implications for practice (progressive disclosure, verifiable, updatable claims, and light gamification that supports information) as well as for evaluation research (comparative or longitudinal designs with behavioral endpoints).
