Assembly Operations

AbstractThe design and verification of assembly operations is essential for planning product production operations. Recently, virtual prototyping has witnessed tremendous progress, and has reached a stage where current environments enable rich and multi-modal interaction between designers and models through stereoscopic visuals, surround sound, and haptic feedback. The benefits of building and using Virtual Reality (VR) models in assembly process verification are discussed in this paper. In this paper, we present the virtual assembly (VA) of an aircraft turbine engine. The assembly parts and sequences are explained using a virtual reality design system. The system enables stereoscopic visuals, surround sounds, and ample and intuitive interaction with developed models. A special software architecture is suggested to describe the assembly parts and assembly sequence in VR. A collision detection mechanism is employed that provides visual feedback to check the interference between components. The system is tested for virtual prototype and assembly sequencing of a turbine engine. We show that the developed system is comprehensive in terms of VR feedback mechanisms, which include visual, auditory, tactile, as well as force feedback. The system is shown to be effective and efficient for validating the design of assembly, part design, and operations planning.

Assessment Activities

Web-based peer assessment has been considered an important process for learning. However, students may not offer constructive feedback due to lack of expertise knowledge. Therefore, this study proposed a scaffolded assessment approach accordingly. To evaluate the effectiveness of the proposed approach, the quasi-experimental design was employed to investigate the effects of scaffolded assessment for self-critiques and peer assessment on students' learning effectiveness in the web-based assessment activities. A total of ninety 7th graders participated in the experiment, and divided into three groups with or without the scaffolding critique. The results show the use of the scaffolded assessment in the web-based peer assessment activities did not show a significant difference in the students' learning effectiveness. Even though the results show that learning effectiveness of the participants in the two experimental groups is significantly enhanced, there is no significant effect of providing the scaffolded assessment on the participants' learning effectiveness in the three groups. In addition, the participants showed a positive learning attitude toward the web-based assessment activities and agreed that the activities could enhance the participants' interactions between the peers and instructor.

Assessment Approach

The chapter discusses the development of a peer assessment approach in an online learning community. Peer assessment is an important construct because it is connected with self-regulated learning and correlated with the use of feedback, two of the most effective issues in facilitating online learning. The aim of the research is to demonstrate the innovative value of peer assessment and peer learning in new tech through a literature review and an analysis of a practical application to show future development in this field.

In this paper, a series of interface tests on interaction approach for the generation of geometric shape designs via multi-sensory user interface of a Virtual Reality (VR) based System is presented. The goal of these interface tests is to identify an effective user interface for VR based Computer-Aided Design (CAD) system. The intuitiveness of the VR based interaction approach arises from the use of natural hand movements/gestures, and voice commands that emulate the way in which human beings discuss geometric shapes in reality. The focus of this paper is on determining a set of effective interaction approaches by using the combinations of auditory, tactile, and visual sensory modalities to accomplish typical CAD tasks. In order to evaluate the proposed interaction approach, a prototypical VR-CAD system is implemented. A series of interface tests were performed on the prototypical systems to determine the relative efficiency of a set of potential interaction approach with respect to specific fundamental design tasks. The interface test and its results are presented in this paper.
