Abstract [en]

We present ASP Modulo ‘Space-Time’, a declarative representational and computational framework to perform commonsense reasoning about regions with both spatial and temporal components. Supported are capabilities for mixed qualitative-quantitative reasoning, consistency checking, and inferring compositions of space-time relations; these capabilities combine and synergise for applications in a range of AI application areas where the processing and interpretation of spatio-temporal data is crucial. The framework and resulting system is the only general KR-based method for declaratively reasoning about the dynamics of ‘space-time’ regions as first-class objects.

Abstract [en]

Cognitive media studies has developed as an area of research at the interface of disciplines as diverse as aesthetics, psychology, neuroscience, film theory, and cognitive science. In this context, the focus of this talk is on the foundational significance of artificial intelligence and visuo-spatial cognition and computation for the design of inte-grated analytical–empirical methods for the (multi-modal) analysis of human behaviour data vis-a-vis a range of digital visuo-auditory narrative media (e.g., narrative film). The presentation focusses on the methodological foundations and assistive technologies for systematic formalization and empirical analyses aimed at, for instance, the generation of evidence, establishing and characterizing correlates between principles for the synthesis of the moving image (e.g., from a cinematographic viewpoint), and its perceptual recipient effects and influence on observers.

In the backdrop a range of completed and ongoing experiments, we emphasize the core results on the semantic interpretation of human behaviour vis-a-vis narrative film and its visuo-auditory reception. We demonstrate the manner in which AI-based models for machine coding of narrative, and relational inference and learning serves as basis to externalize explicit and inferred knowledge about embodied visuo-auditory reception, e.g., using modalities such as diagrammatic representations, natural language, complex (dynamic) data visualizations.

Demonstration: The presentation will particularly showcase methods and tools developed to perform perceptual narrativisation or sensemaking with multi-modal, dynamic human-behaviour data (combining visuo-spatial imagery such as film/video, eye-tracking, head-tracking during a perception task) for a chosen set of experimental material based on existing films, as well as lab-developed experimental content.

Abstract [en]

Decision points in a wayfinding path are considered not only the intersections but also changes in geometry and in directions, merging of paths, or transitions. Carpman and Simmon (1986) pinpoint the need for environmental cues in these points where users’ confusion arises. In this study, we investigate the morphology and the manifest cues of the decision points in relation to the visuo-locomotive behaviour of users recorded during a wayfinding case-study conducted in two healthcare buildings at the Parkland Hospital (Dallas).

We collect and analyse the embodied visuo-locomotive experience of 25 participants, using eye-tracking, external cameras, behavioural mapping, questionnaires, interviews, and orientations tasks. In our multi-modal qualitative analysis, founded in Spatial Reasoning, Cognitive Vision, and Environmental Psychology, we focus on the aspects of visual perception, decision making, orientation, and spatial knowledge acquisition. The comparison between users’ transition in eight decision points involves correlations between occurrences of confusion-related events, detection and categorisation of manifest cues, navigation performance, as well as visual attention analysis in relation to the available spatial features.

Primary results suggest that (1) stop and looking-around behaviour mostly emerge in the decision points; (2) behaviour that indicates confusion is mostly encoded in narrow and enclosed decision points; (3) transitional spaces intensify visual search; (4) visibility ahead of time, and visual disruptions affect the visuo-locomotive behaviour; and (5) detection of manifest cues is affected by the morphology of decision points. The correlations between behavioural and morphological data encoded to conceptual language can be useful as a baseline for computationally-driven behavioural analysis.

Abstract [en]

This presentation focusses on the analysis and design of human-centered, embodied, cognitive user experiences from the perspectives of spatial cognition and computation, artificial intelligence, and human-computer interaction research. Focusing on large-scale built up spaces (in particular hospitals), this presentation will particularly address:

‘how can human-centered cognitive modalities of visuo-locomotive perception constitute the foundational building blocks of design education, discourse, systems, and the professional practice of spatial design for architecture’.

The presentation will emphasizeevidence-based multimodality studies from the viewpoints of visuo-locomotive (i.e., pertaining to vision, movement, and wayfinding) cognitive experiences. Modalities being investigated include: (1) visual attention (by eye-tracking), gesture, language, facial expressions; (2) human expert guided event segmentation (e.g., coming from behavioral or environmental psychologists, designers, annotators); (3) deep analysis based on dialogic components, think-aloud protocols. We demonstrate (1–3) in the context of a large-scale study conducted at the Old and New Parkland Hospitals in Dallas, Texas.

This research (and symposium) calls for a tightly integrated approach combining analytical methods (rooted in AI and computational cognition) and empirical methods (rooted in psychology and perception studies) for developing human-centered architectural design technologies, and technology-mediated (architectural) design synthesis.

Abstract [en]

This symposium—conducted in two parts—explores the confluence of empirically-based qualitative research in the cognitive and psychological sciences (focusing on visual and spatial cognition) with computationally-driven analytical methods (rooted in artificial intelligence) in the service of communications, media, design, and human behavioural studies. With a focus on architecture and visuo-auditory media design, the twin-symposia will demonstrate recent results and explore the synergy of research methods for the study of human behaviour in the chosen (design) contexts of socio-cultural, and socio-technological significance.

The symposium brings together experts and addresses methodsand perspectives from:

•  Visuo-Spatial Cognition and Computation

•  Artificial Intelligence, Cognitive Systems

•  Multimodality and Interaction

•  Cognitive Science and Psychology

•  Neuroscience

•  Design Cognition and Computation

•  Communications and Media Studies

•  Architecture, Built Environment

•  Design Studies (focus on architecture and visuo-auditory media)

•  Evidence Based Design

The symposium particularly emphasises the role of multimodality and mediated interaction for the analysis and design of human-centered, embodied, cognitive user experiences in everyday life and work. Here, the focus is on multimodality studies aimed at the semantic interpretation of human behaviour, and the empirically-driven synthesis of embodied interactive experiences in real world settings. In focus are narrative media design, architecture and built environment design, product design, cognitive media studies (film, animation, VR, sound and music design), and user interaction studies. In these contexts, the symposium emphasizes evidence-based multimodality studies from the viewpoints of visual (e.g.,attention and recipient effects), visuo-locomotive (e.g. , movement, wayfinding), and visuo-auditory (e.g., narrative media) cognitive experiences. Modalities being investigated include, but are not limited to:

•  visual attention (by eye-tracking), gesture, speech, language, facial expressions, tactile interactions, olfaction, biosignals;

•  human expert guided event segmentation (e.g. coming from behavioral or environmental psychologists, designers, annotators,crowd-sensing)

•  deep analysis based on dialogic components, think-aloud protocols

The scientific agenda of the twin-symposia also emphasizes the multi-modality of the embodied visuo-spatial thinking involved in ‘‘problem-solving’’ for the design of objects, artefacts, and inter-active people-experiences emanating there from. Universality andinclusion in ‘‘design thinking’’ are of overarching focus in all design contexts relevant to the symposium; here, the implications of mul-timodality studies for inclusive design, e.g.,creation of presentations of the same content in different modalities, are also of interest. The symposium provides a platform to discuss the development of next-generation embodied interaction design systems, practices, and (human-centered) assistive frameworks and technologies encompassing the multi-faceted nature of embodied design conception and synthesis. Individual contributions/talks within the two symposia address the themes under consideration from formal, computational, cognitive, design, engineering, empirical, and philosophical perspectives.

Abstract [en]

Parametric design systems serve as powerful assistive tools in the design process by providing a flexible approach for the generation of a vast number of design alternatives. However, contemporary parametric design systems focus primarily on low-level engineering and structural forms, without an explicit means to also take into account high-level, cognitively motivated people-centred design goals.

We present a precedent-based parametric design method that integrates people-centred design “precedents” rooted in empirical evidence directly within state of the art parametric design systems. As a use-case, we illustrate the general method in the context of an empirical study focusing on the multi-modal analysis of wayfinding behaviour in two large-scale healthcare environments. With this use-case, we demonstrate the manner in which: (1). a range of empirically established design precedents —e.g., pertaining to visibility and navigation— may be articulated as design constraints to be embedded directly within state of the art parametric design tools (e.g., Grasshopper); and (2). embedded design precedents lead to the (parametric) generation of a number of morphologies that satisfy people-centred design criteria (in this case, pertaining to wayfinding).

Our research presents an exemplar for the integration of cognitively motivated design goals with parametric design-space exploration methods. We posit that this opens-up a range of technological challenges for the engineering and development of next-generation computer aided architecture design systems.

Abstract [en]

Navigation performance in urban and large-scale built-up spaces (e.g. airports, train-stations, hospitals) depends on gradual environmental perception during locomotion, and spatial knowledge acquisition, update/integration at different times along a path. Rotational locomotion is regularly involved in everyday navigation; this, combined with the fact that people cannot perceive the whole of a large-scale setting at once often leads to incidents of cognitive loading and disorientation. Our research explores the mechanisms involved in rotational locomotion for human navigators, and the role of familiarity as well as the cost of cognitive load on orientation accuracy and spatial memory. We examine the impact of structural and featural cues on spatial knowledge updating in relation to egorotations from the viewpoint of behaviour-based design practice and evidencebased design interventions. The results are based on a case study in a train station, experimenting on rotational problems in navigation. Here we present preliminary results emphasizing the role of environmental cues in rotational location, outline possibilities for further study, and discuss implications for evidence-based design practice and cognitive design assistance technology development.

Abstract [en]

We present a computational model for the semantic interpretation of symmetry in naturalistic scenes. Key features include a human-centred representation, and a declarative, explainable interpretation model supporting deep semantic question-answering founded on an integration of methods in knowledge representation and deep learning based computer vision. In the backdrop of the visual arts, we showcase the framework's capability to generate human-centred, queryable, relational structures, also evaluating the framework with an empirical study on the human perception of visual symmetry. Our framework is driven by the application and integration of methods for foundational vision, knowledge representation, and reasoning to the arts, while incorporating evidence from the psychological and social sciences.

Abstract [en]

Spatial knowledge updating is the ability to keep track of one’s position and orientation while moving with respect to the locations such as the starting point. In everyday navigation tasks that involve rotational locomotion, spatial updating frequently fails as a result of the alignment effect, referring to human’s inability to coordinate various spatial representations and reference frames, and human’s tendency to ignore proprioceptive, visual and auditory cues, as a result of changes in perspective, scale, or orientation.

In our empirical study conducted in a large-scale built-up environment, the railway station in Bremen, we investigate if and how rotational locomotion affects the navigation performance in a naturalist every-day task of departure and arrival. The experimental group performs an ego-turn of 360◦ as part of the route while they are able to use all the proprioceptive, visual and auditory cues available to initiate a corresponding counter-rotation of the world. The control group performs the same task without rotational locomotion. Participants were categorised according to the level of familiarity with the environment. We use a multi-modal approach (e.g. orientation task, eye-tracking, questionnaires, videos) to investigate user’s spatial behaviour, focusing on the disorientation effect, and the visuo-spatial features they use for reorientation.

Primary results confirm previous studies suggested that spatial updating is not automatic, it is affected by rotational locomotion and it depends on the level of familiarity of users with the environment. Familiar users tend to proceed an instantaneous spatial updating using different visuo-spatial features than unfamiliar users. Individual differences (gender, mental rotation abilities) are excluded in this study but they are considered significant as a next step. We conclude that people are affected differently by the rotational locomotion, they follow various strategies for reorientation, and so the environment should provide a range of visuo-spatial information to address the user groups.
