A convenient way to test Urban Search And Rescue (USAR) robots would be in virtual environments (VEs). Evaluations in VEs are generally accepted as alternative for real scenarios. There are obvious differences between operation in a real and virtual environment. Nonetheless, the current experiment showed no significant differences in situation...

Freeman et al. reported that a substantial minority of the general population has paranoid thoughts while exposed in a virtual environment. This suggested that in a development phase of a virtual reality exposure system for paranoid patients initially a non-clinical sample could be used to evaluate the system's ability to induce paranoid...

With the rise of user generated content, evaluating the credibility of information has become increasingly important. It is already known that various user characteristics influence the way credibility evaluation is performed. Domain experts on the topic at hand primarily focus on semantic features of information (e.g., factual accuracy),...

In urban search and rescue (USAR) situations resources are limited and workload is high. Robots that act as team players instead of tools could help in these situations. A Virtual Reality (VR) experiment was set up to test if team performance of a human-robot team increases when the robot act as such a team player. Three robot settings were...

The authors added task-relevant sounds to a computer-mediated instructor in-the-loop virtual training for firefighter commanders in an attempt to raise the engagement and arousal of the users. Computer-mediated training for crew commanders should provide a sensory experience that is sufficiently intense to make the training viable and effective....

This paper discusses and evaluates an agent model that is able to manipulate the visual attention of a human, in order to support naval crew. The agent model consists of four sub-models, including a model to reason about a subject's attention. The model was evaluated based on a practical case study which was formally analyzed and verified using...

Event-related potential (ERP) based brain-computer interfaces (BCIs) employ differences in brain responses to attended and ignored stimuli. When using a tactile ERP-BCI for navigation, mapping is required between navigation directions on a visual display and unambiguously corresponding tactile stimuli (tactors) from a tactile control device:...

Tactile and haptic interaction is becoming increasingly important; ergonomic standards can ensure that systems are designed with sufficient concern for ergonomics and interoperability. ISO (through working group TC159/SC4/WG9) is developing international standards in this subject area, dual-tracked as both ISO and CEN standards. A framework and...

Credibility evaluation has become a daily task in the current world of online information that varies in quality. The way this task is performed has been a topic of research for some time now. In this study, we aim to extend this research by proposing an integrated layer model of trust. According to this model, trust in information is influenced...

People with social phobia have a severe fear of everyday social situations. In this paper we describe a virtual reality exposure therapy system specifically designed to expose patients with social phobia to various social situations. Patients can engage in a free speech dialogue with avatars while being monitored by a therapist. To control...

Wikipedia is becoming widely acknowledged as a reliable source of encyclopedic information. However, concerns have been expressed about its readability. Wikipedia articles might be written in a language too difficult to be understood by most of its visitors. In this study, we apply the Flesch reading ease test to all available articles from the...

Serious games offer an opportunity for learning communication skills by practicing conversations with one or more virtual characters, provided that the character(s) behave in accordance with their assigned properties and strate-gies. This paper presents an approach for developing virtual characters by using the Belief-Desire-Intentions (BDI)...

Pilot Safety was truly a cooperation between different parties. With a team of experts, and a group of domain experts for external consultation, the team was able to successfully develop a serious game for mayors. Almost all of the mayors in the Netherlands have now played the game. Without exception, the responses were tremendously enthusiastic...

Decisions and judgments made after deliberation can differ from expert opinion and be more regretted over time than intuitive judgments and decisions. We investigated a possible underlying process of this phenomenon, namely global versus local processing style. We argue that deliberation induces a local processing style. This processing style...

In many games, players communicate with virtual characters. Using the traditional approach of handling dialogues, players often experience the communication as rigid and unnatural. TNO and RANJ explored the BDI approach to create unique virtual characters, each fitted with their individual goals and strategies. The virtual characters initiate...

We present an overview of our recent progress and the current state-of-the-art techniques of color image fusion for night vision applications. Inspired by previously developed color opponent fusing schemes, we initially developed a simple pixel-based false color-mapping scheme that yielded fused false color images with large color contrast and...

How can you tell whether someone working or gaming is mentally taxed too high or too low? In collaboration with Noldus IT (Wageningen) and the FC Donders Institute (Nijmegen), TNO designed and conducted an experiment to measure mental load through brain signals. 35 participants performed a computer task that varied in difficulty. Our classifiers...

A decision support tool, called Speed and Route Advisor (SARA), was developed at Schiphol Airport to help air traffic controllers achieve increased accuracy in traffic delivery. Its influence on controller performance, workload, and situation awareness was evaluated in a real-time simulation and in an operational trial. The findings indicate...

This paper presents a Cognitive Task Load (CTL) model designed to keep track of an operator’s mental workload, both quantitatively (amount of workload) and qualitatively (cognitive state). By integrating this model in a (semi-)autonomous robot, robot’s level of automation and user interface can be attuned to the operator’s state (Every second,...
