Abstract-Nowadays, an increasing need of intervention robotic systems can be observed in all kind of hazardous environments. In all these intervention systems, the human expert continues playing a central role from the decision-making point of view. For instance, in underwater domains, when manipulation capabilities are required, only Remote Operated Vehicles, commercially available, can be used, normally using master-slave architectures and relaying all the responsibility in the pilot. Thus, the role played by human-machine interfaces represents a crucial point in current intervention systems. This paper presents a User Interface Abstraction Layer and introduces a new procedure to control an underwater robot vehicle by using a new intuitive and immersive interface, which will show to the user only the most relevant information about the current mission. We conducted an experiment and found that the highest user preference and performance was in the immersive condition with joystick navigation.
Abstract—The use of emergent technologies in the classroom is mandatory since very early stages considering their presence everywhere, from entertainment to the advertisement areas. Recognizing that fundamentals in electricity have very low level of popularity in secondary schools, different applications have been developed to test the interest of following in the future other developing tools in this field based in augmented reality technologies. The work describes the use of one of the applications tested with students 12 to 14 years old in terms of adequacy, student engagement and student achievement of specific goals. A technical short description is included as well as the implementation of the test with secondary students. Results from this study show that the use of AR applications has effective potential to be used in the classroom as an experimental tool, stimulates student engagement in class activities and enables students to build a self-efficacy in AR use being a good predictor for students’ learning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
