- ZeitschriftenartikelAnalyzing the Effects of VGI-based Landmarks on Spatial Memory and Navigation Performance(KI - Künstliche Intelligenz: Vol. 31, No. 2, 2017) Bestgen, Anne-Kathrin; Edler, Dennis; Kuchinke, Lars; Dickmann, FrankThe construction and modulation of cognitive maps relies on spatial information. Their analysis is essential to understand the orientation and navigation behavior in humans. Empirical studies within the interdisciplinary cooperation of Professor Dickmann at Ruhr-University Bochum and Professor Kuchinke at the International Psychoanalytical University Berlin focus on the investigation of spatial memory and navigation performance, from a cognitive and a geographic perspective. Several studies found out that the design of topographic maps has a systematical influence on spatial memory performance. Within the frame of the Priority Programme SSP 1894 “Volunteered Geographic Information (VGI): Interpretation, Visualisation and Social Computing”, which is funded by the German Research Foundation with a term of 3 years, similar effects of landmarks and landmarks configurations will be investigated. Selected landmarks and, in particular, patterns of landmarks building geometric shapes are expected to guide spatial attention and support individual wayfinding strategies. Identifying landmark patterns will lay the foundations for automatic extraction processes and mobile map design.
- ZeitschriftenartikelCognitive Space and Spatial Cognition: The SFB/TR 8 Spatial Cognition(KI - Künstliche Intelligenz: Vol. 30, No. 1, 2016) Ragni, Marco; Barkowsky, Thomas; Nebel, Bernhard; Freksa, ChristianSpace and time are two of the most fundamental categories any human, animal, or other cognitive agent such as an autonomous robot has to deal with. They need to perceive their environments, make sense of their perceptions, and make interactions as embodied entities with other agents and their environment. The theoretical foundations and practical implications have been investigated from a cognitive perspective (i.e., from an information processing point of view) within the Sonderforschungsbereich/Transregio SFB/TR 8 Spatial Cognition (http://www.sfbtr8.spatial-cognition.de) over the past 12 years jointly by the Universities of Bremen and Freiburg. The research covered fundamental questions: what are the specific requirements of reasoning about space and time, for acting in space, and for any form of interaction including communication in spatio-temporal domains? It has been a success story in all research lines from foundational research to applications of spatial cognition in robotics, interaction and communication. The SFB/TR 8 actually shaped a new research field by extending a previous subfield of cognitive science with its own interdisciplinary techniques.
- ZeitschriftenartikelLandmarks are Exaggerated(KI - Künstliche Intelligenz: Vol. 31, No. 2, 2017) Montello, Daniel R.In this discussion essay, I contend that the role of landmarks is exaggerated in basic and applied spatial cognition research. Specifically, I discuss empirical and theoretical arguments consistent with two claims. First, the word landmark is a label for several different concepts, although its precise reference in a particular context is rarely specified carefully. Further, whether specified or not, researchers never use the term landmark to mean everything that the concept can legitimately mean. Thus, when researchers assert something about the role of landmarks in spatial cognitive activities, they exaggerate their particular meaning at the expense of a broader ontology. Second, I claim that even when landmarks are clearly and precisely defined, their role in specifying location is misunderstood and less fundamental than proposed. In exaggerating landmarks, other important components of spatial knowledge, memory, and reasoning are undervalued. Taken together, these two claims support my contention that landmarks are exaggerated in spatial cognition.
- ZeitschriftenartikelSemantic Interpretation of Multi-Modal Human-Behaviour Data(KI - Künstliche Intelligenz: Vol. 31, No. 4, 2017) Bhatt, Mehul; Kersting, KristianThis special issue presents interdisciplinary research—at the interface of artificial intelligence, cognitive science, and human-computer interaction—focussing on the semantic interpretation of human behaviour. The special issue constitutes an attempt to highlight and steer foundational methods research in artificial intelligence, in particular knowledge representation and reasoning, for the development of human-centred cognitive assistive technologies. Of specific interest and focus have been application outlets for basic research in knowledge representation and reasoning and computer vision for the cognitive, behavioural, and social sciences.
- ZeitschriftenartikelSpatial Cognition of Humans and Brain-inspired Artificial Agents(KI - Künstliche Intelligenz: Vol. 29, No. 1, 2015) Hamker, FredPresent vision systems primarily operate on still images or an image sequence but hardly consider continuous perception across actions. If sensors are attached to the body of a human-like agent who interacts with the environment, several questions arise about how to update the reference systems with each action. In our European research project “Spatial Cognition” we address this topic by a combination of experimental and computational work which should finally merge into a large-scale model of human-like space perception and spatial memory being tested on a humanoid agent in virtual reality.
- ZeitschriftenartikelVisual Landmarks are Exaggerated: A Theoretical and Empirical View on the Meaning of Landmarks in Human Wayfinding(KI - Künstliche Intelligenz: Vol. 34, No. 4, 2020) Hamburger, KaiAre landmarks exaggerated in human wayfinding? Daniel R. Montello says yes, and I basically agree with his opinion. However, I do agree on a different level. My aim for this discussion article is to point out why landmarks are indeed exaggerated in this research context and I will try to approach this claim from several perspectives. First, the research focus in this field is, unfortunately, mainly on visual landmarks. Second, other modalities than vision—e.g., auditory and/or olfactory senses—can be used for landmark-based wayfinding. Third, we need to clearly differentiate between conscious/effortful and unconscious/automatic processing of spatial information in the context of landmark-based wayfinding. Finally, I will suggest that landmarks, even if exaggerated in the visual domain, are (still) of significant importance in human wayfinding and spatial cognition.
