“…This device allows 6DOF input for the user and provides 3DOF haptic feedback, providing the user with a sense of weight, surface texture stiffness and 3D shape. This has been shown to be useful for the design of products in virtual space [40].…”

Current tools used to carry out design for manufacture and assembly (DFMA) evaluations are time consuming to use. This increases the cost of bringing a product to market by extending the length of the design process. The steps that comprise the design, analysis and redesign process are typically carried out in series over long periods of time using different tools. Introducing concurrent engineering practices could significantly reduce the time taken to complete this process and improve workplace DFMA learning. An opportunity exists to create and test an integrated real-time DFMA tool using the UNITY game engine, which could potentially address these problems. If this approach can be achieved it has the potential to decrease the time taken for the design process and enable a greater number of solutions to be considered potentially leading to a more optimal design solution. Having a more optimal design could lead to major cost reduction in later stages of product development by reducing the work needed to plan and carry out the manufacturing process and creating a product that is easier and less costly to maintain. This paper reports on a pilot haptic sketch-based system to investigate its feasibility to conduct concurrent DFMA. .

“…The collision information between the virtual cursor and the virtual brain model is transmitted to the haptic device through the serial interface, driving the motor to generate torque, and finally acting on the end handle. 21 Therefore, the trainer operates the haptic device to control the virtual surgical instrument and feel haptic feedback. The Side-Distance is less affected by the curvature of the scalp due to the small distance from the midline of the brain.…”

Background: The implementation of lateral ventricle puncture (LVP) operation is challenging due to the complex anatomy structure of human brains. Surgical simulator has been proved to be effective in surgical training. However, few works consider the integration of visual and haptic feedback. Methods: Aim at achieving a realistic haptic interaction, this paper proposes a haptic-based virtual reality (VR) simulator for the LVP operation. In this simulator, we first reconstruct the three-dimension (3D) model of human brains for tissue/ instrument interaction. Then a preoperative planning method based on geometry analysis is introduced to find the feasible entry point of LVP operation. A hierarchical bounding-box collision detection approach is proposed to render haptic feedback that is transferred to humans. Finally, a set of experiments on the proposed simulator and 3D printed models of human brains is carried out. Results: Two sets of experiments are conducted to evaluate the effectiveness of the proposed haptic-based simulator: experiments in the simulator and experiments on a 3D printed brain model. The proposed simulator allows neurosurgeons to train the LVP operation by visualizing the 3D virtual human brain and feeling realistic haptic feedback. Conclusions: We demonstrated that the proposed haptic-based VR simulator can improve the performance of the LVP operation effectively and reduce the operation time.

Web-based stakeholders’ participation in product co-design is an emerging business model for companies. However, research on user’s online involvement in product co-design is limited. In this paper, we investigated the three major interdisciplinary academic databases Web of Science, Scopus, and ScienceDirect (data collected in May 2020), with the aim of explaining the meaning, core concepts, historical roots, and research trends of co-design. A total of 39 of the deemed relevant studies were emphatically analyzed, systematically discusses the concept implication and development status of co-design, and the key points of web-based product co-design research, as well as the future research direction.
