Spatial relations play an important role in the research area of connecting visual and verbal space. In the last decade several approaches to semantics and computation of spatial relations in 2D space have been developed. Presented here is a new approach to the computation and evaluation of basic spatial relations’ meanings in 3D space. We propose the use of various kinds of approximations when...

Spatial scaffolding is a naturally occurring human teaching behavior, in which teachers use their bodies to spatially structure the learning environment to direct the attention of the learner. Robotic systems can take advantage of simple, highly reliable spatial scaffolding cues to learn from human teachers. We present an integrated robotic architecture that combines social attention and machin...

This contribution discusses a site selection process for establishing a local park. It was supported by a value-focused approach and spatial multi-criteria evaluation techniques. A first set of spatial criteria was used to design a number of potential sites. Next, a new set of spatial and non-spatial criteria was employed, including the social functions and the financial costs, together with th...

In this paper we propose a novel spatial fading simulator to evaluate the performance of an array antenna and show its spatial stochastic characteristics by computer simulation based on parameters verified by experimental data. We introduce a cavity-excited circular array (CECA) as a fading simulator that can simulate realistic mobile communication environments. To evaluate the antenna array, t...

In this paper, two kinds of evaluation index for the haptic motion analysis in parallel multiple degrees–of– freedom (MDOF) system are proposed. At first, the spatial modal decomposition method based on discrete Fourier series expansion (DFS) is presented. Spatial modal information expresses a motion element that corresponds to a specific physical action. The spatial modal information can mathe...

This paper proposes real-time performance evaluation metrics for the object detection and tracking algorithms used in intelligent video surveillance systems. Since an intelligent video surveillance system should support real-time performance, as well as the spatial accuracy of the object detection and tracking, the performance evaluation tool should evaluate not only the spatial accuracy, but a...

Spatial visualization of engineering students is of greatest importance in terms of their professional achievement, thus evaluation of this skill is essential. Mental Cutting Test (MCT) is one of the most widely used evaluation method for spatial abilities. In this study we present an analysis of MCT results of first-year engineering students, with special emphasis on gender differences. Simila...
