lambdaProlog(QS): Functional Spatial Reasoning in Higher Order Logic Programming (Short Paper)

Authors: Beidi Li, Mehul Bhatt, and Carl Schultz

Published in: LIPIcs, Volume 142, 14th International Conference on Spatial Information Theory (COSIT 2019)

Abstract
We present a framework and proof-of-concept implementation for functional spatial reasoning within high-order logic programming. The developed approach extends lambdaProlog to support reasoning over spatial variables via Constraint Handling Rules. We implement our approach within Embeddable lambdaProlog Interpreter (ELPI) and demonstrate key features from combined reasoning over spatial functions and relations. The reported research is an ongoing development of the declarative spatial reasoning paradigm.

Evidence-Based Parametric Design: Computationally Generated Spatial Morphologies Satisfying Behavioural-Based Design Constraints

Authors: Vasiliki Kondyli, Carl Schultz, and Mehul Bhatt

Published in: LIPIcs, Volume 86, 13th International Conference on Spatial Information Theory (COSIT 2017)

Abstract
Parametric design is an established method in engineering and architecture facilitating the rapid generation and evaluation of a large number of configurations and shapes of complex physical structures according to constraints specified by the designer. However, the emphasis of parametric design systems, particularly in the context of architectural design of large-scale spaces, is on numerical aspects (e.g., maximising areas, specifying dimensions of walls) and does not address human-centred design criteria, for example, as developed from behavioural evidence-based studies. This paper aims at providing an evidence-based human-centred approach for defining design constraints for parametric modelling systems. We determine design rules that address wayfinding issues through behavioural multi-modal data analysis of a wayfinding case study in two healthcare environments of the Parkland hospital (Dallas). Our rules are related to the environmental factors of visibility and positioning of manifest cues along the navigation route. We implement our rules in FreeCAD, an open-source parametric system.

Cognitive Interpretation of Everyday Activities - Toward Perceptual Narrative Based Visuo-Spatial Scene Interpretation

Authors: Mehul Bhatt, Jakob Suchan, and Carl Schultz

Published in: OASIcs, Volume 32, 2013 Workshop on Computational Models of Narrative

Abstract
We position a narrative-centred computational model for high-level knowledge representation and reasoning in the context of a range of assistive technologies concerned with visuo-spatial perception and cognition tasks. Our proposed narrative model encompasses aspects such as space, events, actions, change, and interaction from the viewpoint of commonsense reasoning and learning in large-scale cognitive systems. The broad focus of this paper is on the domain of human-activity interpretation in smart environments, ambient intelligence etc. In the backdrop of a smart meeting cinematography domain, we position the proposed narrative model, preliminary work on perceptual narrativisation, and the immediate outlook on constructing general-purpose open-source tools for perceptual narrativisation.
