Significant Difference

Purpose The purpose of this paper is to study the effect of the gamification of virtual assembly planning on the user performance, user experience and engagement. Design/methodology/approach A multi-touch table was used to manipulate virtual parts and gamification features were integrated into the virtual assembly environment. An experiment was conducted in two conditions: a gamified and a non-gamified virtual environment. Subjects had to assemble a virtual pump. The user performance was evaluated in terms of the number of errors, the feasibility of the generated assembly sequence and the user feedback. Findings The gamification reduced the number of errors and increased the score representing the number of right decisions. The results of the subjective and objective analysis showed that the number of errors decreased with engagement in the gamified assembly. The increase in the overall user experience reduced the number of errors. The subjective evaluation showed a significant difference between the gamified and the non-gamified assembly in terms of the level of engagement, the learning usability and the overall experience. Research limitations/implications The effective learning retention after training has not been tested, and longitudinal studies are necessary. The effect of the used gamification elements has been evaluated as a whole; further work could isolate the most beneficial features and add other elements that might be more beneficial for learning. Originality/value The research reported in this paper provides valuable insights into the gamification of virtual assembly using a low-cost multi-touch interface. The results are promising for training operators to assemble a product at the design stage.

Abstract An interactive synthetic environment is presented which allows direct use of geometric component models and hierarchical assembly data in assembly planning and evaluation. The system allows the human designer to exploit inherent knowledge of assembly ordering, design parallelism, and other assembly factors to evaluate and visualize candidate assembly plans. The designer interacts with both geometric and abstract representations of the assembly using virtual environment peripherals such as a head-coupled display, six-degree-of-freedom trackers, and an instrumented glove. The system addresses several problems inherent in algorithmic assembly planning.

Low Efficiency

To deal with the problems of complicated process, difficult operation and low efficiency for large-scale complex products assembly, a new immersive virtual environment (VE) with virtual reality (VR) technology is built in the process of assembly planning and training. The environment is composed of a free walk machine and spherical screen projection system. In this paper, a free walk machine with movement perception function is developed to achieve natural human-computer interaction. And an approach based on two viewpoints match is adopted to improve immersive effect of stereo projection in the projection system. On the basis of that, a geometry calibration method based on Bicubic NURBS(Non-Uniform Rational B-Spline) surface matching target-controlled dot-matrix is proposed to achieve non-distorted image on spherical screen. Finally, the environment is applied in the process of satellite assembly process planning, and the display result shows that the VE development is feasible and valuable.

Simple Assembly

The concept of virtual assembly offers endless possibilities to a designer in a manufacturing setting. Various assembly measures such as clearance, assembly planning, force and alternate designs can be examined without the need to waste resources through manufacturing. This paper investigates the possibility of using force feedback through haptics in a virtual environment as a way of understanding the intricacy of simple assembly. This allows a designer to further understand what will, and will not, work during the design phase. The study of certain characteristics, including lubrication, is also examined to see what impact it has on the ease of assembly. A user, or designer, can then get an actual feel to see what characteristics change the likelihood for a proper fit. In addition, the creation of a virtual part run is also examined to fully understand what constitutes a defect. Statistical output is provided so a user can analyze a run of parts for quality control and be able to pinpoint possible causes for error in a process. Virtual parts can then be assembled from the run to see how each differs from the others and to emphasize the undesirability of a defect for assembly purposes.

Ground-based haptic devices provide the capability of adding force feedback to virtual environments; however, the physical workspace of such devices is very limited due to the fixed base. By mounting a haptic device on a mobile robot, rather than a fixed stand, the reachable volume can be extended to function in full-scale virtual environments. This work presents the hardware, software, and integration developed to use such a mobile base with a Haption Virtuose™ 6D35-45. A mobile robot with a Mecanum-style omni-directional drive base and an Arduino-compatible microcontroller development board communicates with software on a host computer to provide a VRPN-based control and data acquisition interface. The position of the mobile robot in the physical space is tracked using an optical tracking system. The SPARTA virtual assembly software was extended to 1) apply transformations to the haptic device data based on the tracked base position, and 2) capture the error between the haptic device’s end effector and the center of its workspace and command the robot over VRPN to minimize this error. The completed system allows use of the haptic device in a wide area projection screen or head-mounted display virtual environment, providing smooth free-space motion and stiff display of forces to the user throughout the entire space. The availability of haptics in large immersive environments can contribute to future advances in virtual assembly planning, factory simulation, and other operations where haptics is an essential part of the simulation experience.
