Development Prototype Design of Virtual Assembly Application-Based Leap Motion

Innovation in design engineering practice is very important in the world of manufacturing in the increasingly competitive global market. Prototyping and evaluation measures are inseparable from the design process in the manufacture of a product. And made one of many physical prototypes require very expensive and time consuming, so the technology of Virtual Reality (VR) is needed, so the industry can quickly and precisely in the decision. VR technology combines a human being with a computer environment visually, touch and hearing, so that the user as if into the virtual world. The goal is that users with hand movements can interact with what is displayed on the computer screen or the user can interact with the environment is unreal to be added into the real world. VR is required for simulations that require a lot of interaction such as prototype assembly methods, or better known as the Virtual Assembly. Virtual Assembly concept which was developed as the ability to assemble a real representation of the physical model, the 3D models in CAD software by simulating the natural movement of the human hand. Leap Motion (accuracy of 0.01mm) was used to replace Microsoft's Kinect (accuracy of 1.5cm) and Motion Glove with flex sensors (accuracy of 1°) in several previous research. Leap mot ion controller is a device that captures every movement of the hand to then be processed and integrated with 3D models in CAD software. And simulation of assembly process virtually in CA D software with hand gestures detected by the leap mot ion, assembly parts can be driven either in translation or rotation, zooming and adding the assembly constraint. It also can perform mouse functions (such as left-click, middle-click, right-click and move the mouse cursor position) to a virtual assembly process simulation on CAD software.
