Impact of monitor-based augmented reality for on-site industrial manual operations
No full textThis work evaluates the impact of augmented reality (AR) technology to support operators during manual industrial tasks. The work focuses specifically on monitor-based augmented reality as a solution to provide instructions to the operator. Instructions are superimposed directly onto a video representation of the physical workspace and are displayed on a standard monitor. In contrast to previous AR solutions proposed to support manual tasks, the current work is more industrially acceptable because it meets most of the industrial requirements and it is cost effective for a deployment in an industrial environment. The developed prototype is described and evaluated by means of a user study to compare the monitor-based augmented reality solution to provide instructions and the traditional method. The test shows that AR can be a valid substitute to support the operators during manual tasks because it allows them to be more time efficient and it reduces their mental workload compared to traditional instructional manuals
A natural user interface for navigating in organized 3D virtual contents
No full textThe research activity presented in this paper aim at extending the traditional planar navigation, which is adopted by many desktop applications for searching information, to an experience in a Virtual Reality (VR) environment. In particular, the work proposes a system that allows the user to navigate in virtual environments, in which the objects are spatially organized and sorted. The visualization of virtual object has been designed and an interaction method, based on gestures, has been proposed to trigger the navigation in the environment. The article describes the design and the development of the system, by starting from some considerations about the intuitiveness and naturalness required for a three-dimensional navigation. In addition, an initial case study has been carried out and consists in using the system in a virtual 3D catalogue of furniture. © 2014 Springer International Publishing
An augmented reality framework for supporting and monitoring operators during maintenance tasks
No full textThe paper proposes a framework for supporting maintenance services in industrial environments through the use of a mobile device and Augmented Reality (AR) technologies. 3D visual instructions about the task to carry out are represented in the real world by means of AR and they are visible through the mobile device. In addition to the solutions proposed so far, the framework introduces the possibility to monitor the operator's work from a remote location. The mobile device stores information for each maintenance step that has been completed and it makes them available on a remote database. Supervisors can consequently check the maintenance activity from a remote PC at any time. The paper presents also a prototype system, developed according to the framework, and an initial case study in the field of food industry. © 2014 Springer International Publishing
Augmented Reality Interactive System to Support Space Planning ActivitiesVirtual, Augmented and Mixed Reality. Systems and Applications
No full textThe Space Planning (SP) is a process that allows making an environment more ergonomic, functional and aesthetically pleasing. The introduction of Computer Aided tools for this kind of practice led to an increase of the quality of the final result thanks to some versatile support used for the generation of different options to consider for the evaluation. In particular, those based on Augmented Reality (AR) technologies allow evaluating several options directly in a real room. In this paper, an AR system, developed with the aim of supporting Space Planning activities, is proposed. The system has been developed in order to overcome some problems related to the tracking in wide environments and to be usable in different typologies of Space Planning environments. The paper also presents a qualitative evaluation of the AR system in three different scenarios. The positive results obtained through these evaluation tests show the effectiveness and the suitability of the system in different Space Planning contexts
