Context. Software development pipelines are used for automating essential parts of software engineering processes, such as build automation and continuous integration testing. In particular, interactive pipelines, which process events in a live environment such as an IDE, require timely results for low-latency feedback, and persistence to retain low-latency feedback between restarts. Inquiry. D...

Age-related deficits are seen across tasks where learning depends on asocial feedback processing, however plasticity has been observed in some of the same tasks in social contexts suggesting a novel way to attenuate deficits. Socioemotional selectivity theory suggests this plasticity is due to a deliberative motivational shift toward achieving well-being with age (positivity effect) that revers...

The authors investigated whether guidance and reflection would facilitate science learning in an interactive multimedia game. College students learned how to design plants to survive in different weather conditions. In Experiment 1, they learned with an agent that either guided them with corrective and explanatory feedback or corrective feedback alone. Some students were asked to reflect by giv...

Conducting presentations with bidirectional communication requires extended presentation systems with sophisticated expressions and real-time feedback gathering. We aim to develop an interactive presentation system to enhance presentations with bidirectional communication during presentations. We employed a hybrid approach of a traditional presentation supporting system (PowerPoint) and a Web a...

Multi-touch input using multiple fingertips or hands has become the de-facto standard for the interaction with interactive surfaces such as tablets, tabletops or interactive walls. For single touch input, the addition of synchronous tactile feedback has shown to be beneficial in terms of reducing error-rates, increasing interaction speed and minimizing visual load. However, to this day, the non...

There is no dearth of opinion about the use of simulation in support of training, analysis, acquisition, and doctrine development in general. Similarly, there is abundant discourse including technical contributions about the use of distributed interactive simulation (DIS), in particular, in support of these three enterprises. It is arguable that there is no single opinion about the efficacy of ...

With the recent rapid progress of computer technology, researchers have attempted to adopt artificial intelligence and computer networks to develop computer-aided tutoring systems. Meanwhile, some have also attempted to develop more effective programs to test and enhance the learning performance of students. This study surveyed the current theoretical basis and design principle and proposed a w...

New contributors to Wikipedia face daunting technical and social challenges, contributing to ongoing decline in editor retention and systemic bias in article content. The Wikipedia Adventure is a web-based interactive tutorial for new users that leads them through learning essential basics in a safe game-like environment, and can extend to instruction on advanced skills. All interactions are tr...

In this paper we focus on explaining to humans the behavior of autonomous agents, i.e., explainable agents. Explainable agents are useful for many reasons including scenario-based training (e.g. disaster training), tutor and pedagogical systems, agent development and debugging, gaming, and interactive storytelling. As the aim is to generate for humans plausible and insightful explanations, user...

We describe the results of several experiments with interactive interfaces for native and L2 English students, designed to collect implicit feedback from students as they complete a reading activity. In this study, implicit means that all data is obtained without asking the user for feedback. To test the value of implicit feedback for assessing student proficiency, we collect features of user b...
