Buffer scheduling for improving on-time performance and connectivity with a multi-objective simulation–optimization model: A proof of concept for the airline industry

Schedule design in the transportation and logistics sector is a widely studied problem. Transport service providers, such as the train industry and aviation, aim for schedules to be on-time according to the planning (i.e., on-time performance or OTP) in order to increase the service level by ensuring that passengers actually make their...

The validity of simplifying gaming simulations

Simplifications of the real world affect the validity and reliability of gaming simulations. This challenges the application of gaming simulations as an instrument for experiential learning, reflective practices and data collection. This study investigates the effects of simplification on extracting tacit knowledge from human behavior by...

Multimodal interaction technologies for mental well-being: Editorial

On Head Motion for Recognizing Aggression and Negative Affect during Speaking and Listening

Affective aggression is a form of aggression characterized by impulsive reactions driven by strong negative emotions. Despite the extensive research in the area of automatic emotion recognition, affective aggression is a phenomenon that has received less attention. This study investigates the use of head motion as a potential indicator of...

A Cross-Corpus Speech-Based Analysis of Escalating Negative Interactions

The monitoring of an escalating negative interaction has several benefits, particularly in security, (mental) health, and group management. The speech signal is particularly suited to this, as aspects of escalation, including emotional arousal, are proven to easily be captured by the audio signal. A challenge of applying trained systems in real...

Toward Linguistic Recognition of Generalized Anxiety Disorder

<b>Background</b>: Generalized anxiety disorder (GAD) refers to extreme, uncontrollable, and persistent worry and anxiety. The disorder is known to affect the social functioning and well-being of millions of people, but despite its prevalence and burden to society, it has proven difficult to identify unique behavioral markers. Interestingly, the...

The need for a female perspective in designing agent-based negotiation support

This study investigates whether an agent-based Negotiation Training System (NTS) can teach women Strategic Empathy - a recently introduced negotiation strategy based on perspective taking - and whether this can improve their negotiation performance. Developed and tested through an interaction-based real-time experiment was a NTS that integrated...

Re-framing engagement for applied games: A conceptual framework

Although games are frequently described as ‘engaging’, what this means exactly continues to be subject of debate in game literature. Engagement is often defined through related concepts like immersion and positive emotions. However, this neglects the fact that applied games aim to provide more than an entertaining experience, and that engagement...

Incorporating the Theory of Attention in Applied Game Design

Whereas entertainment games are capable of creating deeply rewarding and emotional experiences, applied game projects often result in products that, while potentially effective, are lacking in many other aspects of the user experience. This may be due to the fact that the focus of most design approaches for applied games lies primarily on the...

Dive Deeper: Empirical Analysis of Game Mechanics and Perceived Value in Serious Games

Validation of serious games tends to focus on evaluating their design as a whole. While this helps to assess whether a particular combination of game mechanics is successful, it provides little insight into how individual mechanics contribute or detract from a serious game's purpose or a player's game experience. This study analyses the effect...

The INTERSPEECH 2021 computational paralinguistics challenge: COVID-19 cough, COVID-19 speech, escalation & primates

The INTERSPEECH 2021 Computational Paralinguistics Challenge addresses four different problems for the first time in a research competition under well-defined conditions: In the COVID-19 Cough and COVID-19 Speech Sub-Challenges, a binary classification on COVID-19 infection has to be made based on coughing sounds and speech; in the Escalation...

Spatial factors influencing building age prediction and implications for urban residential energy modelling

Urban energy consumption is expected to continuously increase alongside rapid urbanization. The building sector represents a key area for curbing the consumption trend and reducing energy-related emissions by adopting energy efficiency strategies. Building age acts as a proxy for building insulation properties and is an important parameter for...

Understanding the Potential of Augmented Reality in Manufacturing Environments

Manufacturing companies are confronted with challenges due to increasing flexibility requirements and skill gaps. Augmented Reality applications offer an efficient way to overcome these tensions by enhancing the interaction between people and technology. The positive effects of Augmented Reality solutions are often described in individual models...

Do Gaming Simulations Substantiate That We Know More Than We Can Tell?

Background. Revealing tacit knowledge often is seen as very valuable for organizations, although it is usually challenging to enunciate and share this type of knowledge. Methods. This study uses a participatory design and the application of a board gaming simulation as instruments to extract tacit knowledge. To illustrate this application,...

Multimodal Cross-context Recognition of Negative Interactions

Negative emotions and stress can impact human-human interactions and eventually lead to aggression. From the perspective of surveillance systems, it is of high importance to recognize as soon as an interaction escalates and human intervention is needed. One of the limitations of deploying a system in real life is that in practice it can only be...

Multimodal Surveillance: Behavior analysis for recognizing stress and aggression

Nowadays, camera systems are installed in military areas as well as in public spaces like schools, shopping malls, airports, and football stadiums. Human operators are monitoring the screens, looking for any signs of unwanted behavior and negative incidents. The task requires working personnel 24/7. With the ever increasing number of cameras,...
