IntroductionAugmented reality (AR) is the virtual object which is a combination of a real 3D environment in real time. One of the application areas of augmented reality (AR) is computer-assisted surgery and medicine. In computer-assisted surgery and medicine, a visualization method is needed as a side view of the virtual world as a computer visualization solution in operation, for example in laparoscopic surgery. In this review, visualization includes AR systems based on display device, head-mounted display (HMD), and stereoscopic images to generate images with a new side of view. Meanwhile, minimally invasive therapy (MIT) is used in modern medicine. In a research article (Zhang.L. & .WJ, 2005), the head-mounted display (HMD) described as a monochrome stereoscopic device HMD combined real and virtual images by means of a semi-transparent mirror.MotivationsWhy a reality application augmented in computer-assisted surgery and medicine, an interesting subject? The reason why we conducted these studies is to suggest requirements for improving video transparency HMD systems and stereoscopic images to meet the basic requirements. Augmented reality is one of the leading approaches in the medical field, particularly in surgery and medicine. (Shuhaibar JH, 2004) defined augmented reality as a new approach in performing detailed surgical operations and further research is needed to evaluate long-term clinical outcomes. The requirement in fact of the representation system which allows the doctor to interact naturally and to have experience in a mixed environment such as in a virtual environment. In one study (M.Figl, 2008), HMD is a device for displaying additional computer-generated graphics on a real-world scene. It can also show the life images from the middle of paper...... in Tecgraf/PUC-Rio.SBC Journal on 3D Interactive Systems 2(2), 75-78.E. Samset; D. Schmalstieg; J. Vander Sloten; A. Freudenthal; J.
