Ontology-Based Reflective Communication for Shared Human-AI Recognition of Emergent Collaboration Patterns

When humans and AI-agents collaborate, they need to continuously learn about each other and the task. We propose a Team Design Pattern that utilizes adaptivity in the behavior of human and agent team partners, causing new Collaboration Patterns to emerge. Human-AI Co-Learning takes place when partners can formalize recognized patterns of...

Development and analysis of a real-time system for automated detection of improvised explosive device indicators from ground vehicles

We propose a real-time change detection system to be used as a vehicle-mounted early-warning system for indicators of improvised explosive devices. Within the context of military route clearance, the system automatically detects suspicious changes in the environment with respect to a previous patrol. For this purpose, historical images of the...

An extended protocol for usability validation of medical devices: Research design and reference model

This paper proposes and demonstrates an extended protocol for usability validation testing of medical devices. A review of currently used methods for the usability evaluation of medical devices revealed two main shortcomings. Firstly, the lack of methods to closely trace the interaction sequences and derive performance measures. Secondly, a...

Large scale track analysis for wide area motion imagery surveillance

Wide Area Motion Imagery (WAMI) enables image based surveillance of areas that can cover multiple square kilometers. Interpreting and analyzing information from such sources, becomes increasingly time consuming as more data is added from newly developed methods for information extraction. Captured from a moving Unmanned Aerial Vehicle (UAV), the...

Focus-of-attention for human activity recognition from UAVs

This paper presents a system to extract metadata about human activities from full-motion video recorded from a UAV. The pipeline consists of these components: tracking, motion features, representation of the tracks in terms of their motion features, and classification of each track as one of the human activities of interest. We consider these...

Towards sustainability in cold chains: Development of a quality, energy and environmental assessment tool (QEEAT)

Quantification of the impact of refrigeration technologies in terms of the quality of refrigerated food, energy usage, and environmental impact is essential to assess cold chain sustainability. In this paper, we present a software tool QEEAT (Quality, Energy and Environmental Assessment Tool) for evaluating refrigeration technologies. As a...

MUFASSA, a multipurpose framework to develop GUI’s for underwater acoustic modelling

Underwater acoustic modeling is used in many fields of research and development, which has resulted in a wide variety of acoustic models and applications, such as sensor performance prediction, sensor performance optimizations and acoustic impact on marine life. Many of the applications share a similar set of input parameters: bathymetry, sound...

Development of a Matlab/Simulink tool to facilitate system analysis and simulation via the adjoint and covariance methods

The COVariance and ADjoint Analysis Tool (COVAD) is a specially designed software tool, written for the Matlab/Simulink environment, which allows the user the capability to carry out system analysis and simulation using the adjoint, covariance or Monte Carlo methods. This paper describes phase one of the COVAD evolution, which includes a user...

The multi-dimensional nature of encoding tactile and haptic interactions: From psychophysics to design guidelines

Designers are very well aware of the multi-dimensionality of visual stimuli and extensively use dimensions such as color, form and contrast to encode information. An analogous multi-dimensionality applies to haptic and tactile stimuli. Based on the fact that the human visual system only has two receptor types (cones and rods) while the sense of...

The CIE94 colour difference formula for describing visual detection thresholds in static noise

The parametric factors kL, kC and kH that scale the CIELAB components kL*, kC* and kH* in the CIE94 colour difference formula are unity under reference conditions. When the conditions are changed, the scaling factors may be adapted to account for the influence of specific experimental conditions on perceived colour differences. We determined...

Interaction design concepts for a mobile personal assistant

The Personal Assistant for onLine Services (PALS) project aims to develop an intelligent interface that facilitates efficient user interaction through personalization and context awareness with commerce web sites on a handheld device. The types of assistance services and interaction support represented by a mobile personal assistant have been...

Virtual reality applied to teletesting

The activity "Virtual Reality applied to Teletesting" is related to a wider European Space Agency (ESA) initiative of cost reduction, in particular the reduction of test costs. Reduction of costs of space related projects have to be performed on test centre operating costs and customer company costs. This can accomplished by increasing the...

Improving user-friendliness by using visually supported speech recognition

While speech recognition in principle may be one of the most natural interfaces, in practice it is not due to the lack of user-friendliness. Words are regularly interpreted wrong, and subjects tend to articulate in an exaggerated manner. We explored the potential of visually supported error correction (speech recognition integrated in a...

Automatic video analysis and compilation system AVACS

The analysis of video observation tapes can be tedious and tiring work. An analysis system can relieve this burden and create a compilation tape autonomously. Working unattended AVACS creates a tape and a Compact Disk (CD) with only the images-of-interest.
