Pilegi, S.F. and Amor, R. (2015) Semantic Geographic Space: From Big Data to Ecosystems of Data, in Hassanien, A.-E., Taher Azar, A., Snasel, V., Kacprzyk, J. and Abawajy, J.H. (Eds), Big Data in Complex Systems, Challenges and Opportunities Series: Studies in Big Data, 9, ISBN 978-3-319-11055-4, pp. 351-374. |
Abstract: Enhancing the physical view of a geographic space through the integration of semantic models enables a novel extended logic context for geographic data infrastructures that are modelled as an ecosystem of data in which semantic properties and relations are defined with the concepts composing the model. The signigicant capabilities of current semantic technology allow the implementation of rich data models according to an ontological approach that assures competitive interoperable solutions in the context of environments for general purpose (e.g. the Semantic Web) as well as inside more specific systems (e.g. Geographic Information Systems). Extended capabilities in terms of expressivity have strong implications also for data/information processing, especially on a large scale (Big Data). Semantic spaces can play a critical role in those processes contrasting the mostly passive role of models simply reflecting a geographic perspective. This chapter proposes a short overview of a simple model for semantic geographic space and a number of its applications, mostly focusing on the added value provided by the use of semantic spaces in different use cases.

Al Manji, A., Payne, A., Amor, R. and Davies, T.C. (2015) A Nonlinear Model for Mouse Pointing Task Movement Time Analysis Based on Both System and Human Effects, IEEE Transactions on Neural Systems and Rehabilitation Engineering, 99, doi:10.1109/TNSRE.2014.2377692, pp. 1003-1011. |
Abstract: This paper provides a detailed model for analyzing movement time performance during rapid goal-directed point-and-click motions with a computer mouse. Twelve typically developed individuals and eight youths with cerebral palsy conducted point and click computer tasks from which the model was developed. The proposed model is nonlinear and based on both system (target width and movement amplitude) and human effects (erroneous clicks, number of submovements, number of slip-offs, curvature index, and average speed).To ensure successful targeting by youths with cerebral palsy, the index of difficulty was limited to a range of 1.58 - 3.0 bits. For consistency, the same range was used with both groups. The most significant contributing human effect to movement time was found to be the curvature index for both typically developed individuals and individuals with cerebral palsy. This model will assist in algorithm development to improve cursor speed and accuracy for youths with cerebral palsy.

Al Manji, A., Davies, T.C. and Amor, R. (2015) Examining Dynamic Control-Display Gain Adjustments to Assist Mouse-Based Pointing for Youths with Cerebral Palsy, International Journal of Virtual Worlds and Human Computer Interaction, 3, DOI: 10.11159/vwhci.2015.001, pp. 1-9. |
Abstract: Youths with cerebral palsy encounter difficulties in target acquisition using mouse-based "point-and-click" tasks. The performance of "point-and-click computer tasks" by youths with cerebral palsy still needs improvement to allow easy target acquisition. The purpose of this study was to evaluate an algorithm intended to enhance the performance of point-and-click computer tasks for youths with cerebral palsy using a standard mouse. The curvature index-based algorithm for dynamic adjustment of control-display gain showed experimentally better performance during primary sub-movement, but worse performance during secondary correction sub-movements (higher number of sub-movements and longer movement time) for both typically developed youths and youths with cerebral palsy. It also showed better performance of average speed and maximum speed compared with Windows default settings. Furthermore, the average movement time, error rate, and overshoot rate for both typically developed youths and youths with cerebral palsy are higher using the curvature index-based algorithm.

Dimyadi, J., Pauwels, P., Spearpoint, M., Clifton, C. and Amor, R. (2015) Querying a Regulatory Model for Compliant Building Design Audit, Proceedings of CIB W78, Eindhoven, The Netherlands, 27-29 October, pp. 139-148. |
Abstract: The ingredients for an effective automated audit of a building design include a BIM model containing the design information, an electronic regulatory knowledge model, and a practical method of processing these computerised representations. There have been numerous approaches to computeraided compliance audit in the AEC/FM domain over the last four decades, but none has yet evolved into a practical solution. One reason is that they have all been isolated attempts that lack any form of standardisation. The current research project therefore focuses on using an open standard regulatory knowledge and BIM representations in conjunction with open standard executable compliant design workflows to automate the compliance audit process. This paper provides an overview of different approaches to access information from a regulatory model representation. The paper then describes the use of a purpose-built high-level domain specific query language to extract regulatory information as part of the effort to automate manual design procedures for compliance audit.

Plimmer, B. and Amor, R. (2015) The Physical - Virtual Nexus, Proceedings of CHI workshop, Seoul, Korea, 18-23 April. |
Abstract: Our interest is in the transformation of data between virtual and physical forms. Recent advances of 3D printing makes it easy to produce a physical 3D model from a virtual model. However there are many undiscovered and unexplored opportunities and issues in this form of human computer interaction. We contribute two projects which have explored different aspects of this space.

Amor, R. (2015) Analysis of the Evolving IFC Schema, Proceedings of CIB W78, Eindhoven, The Netherlands, 27-29 October, pp. 39-49. |
Abstract: The newly released (March 2013) version of the IFC standard for open BIM (IFC4) is a major step forward for this ISO standard. It is reported to represent 8 person years of development effort and to have addressed over 1200 issues and change requests. It is released 6 years after the last major version of IFC (2x3 TC1) reflecting in part the major development effort required by the industry to handle new versions of this large standard (766 entities). While buildingSMART have documented the increased domain coverage over the previous version (e.g., for structural steel and timber, GIS, 5D support, etc) there is also an impact of changes in regards to the complexity and maintainability of the IFC standard. This paper investigates the changes within IFC4 and IFC4 Addendum 1 with respect to schema-level metrics, to understand the directions that the new standard has taken from a data management and implementers point of view. This complements work undertaken in 2007 (Amor et al. 2007) which looked at the impact of the then newly release IFC 2x3. In that study it was identified that there was unnecessary and growing complexity in the schema. This analysis addresses how much effort has been put into the new version to tame the complexity whilst growing its domain coverage.
