“…Today’s surgical medical imaging technology still requires surgeons to look up from time to time to the images on the monitor to aid the progress of the surgery [ 10 ]. Microsoft has developed several Hololens applications for medical treatment [ 11 , 12 ], but most of them have not been applied to the alignment of the virtual images with the human body; instead, the virtual objects are placed in an empty space environment for educational guidance purposes.…”

In many surgery assistance systems, cumbersome equipment or complicated algorithms are often introduced to build the whole system. To build a system without cumbersome equipment or complicated algorithms, and to provide physicians the ability to observe the location of the lesion in the course of surgery, an augmented reality approach using an improved alignment method to image-guided surgery (IGS) is proposed. The system uses RGB-Depth sensor in conjunction with the Point Cloud Library (PCL) to build and establish the patient’s head surface information, and, through the use of the improved alignment algorithm proposed in this study, the preoperative medical imaging information obtained can be placed in the same world-coordinates system as the patient’s head surface information. The traditional alignment method, Iterative Closest Point (ICP), has the disadvantage that an ill-chosen starting position will result only in a locally optimal solution. The proposed improved para-alignment algorithm, named improved-ICP (I-ICP), uses a stochastic perturbation technique to escape from locally optimal solutions and reach the globally optimal solution. After the alignment, the results will be merged and displayed using Microsoft’s HoloLens Head-Mounted Display (HMD), and allows the surgeon to view the patient’s head at the same time as the patient’s medical images. In this study, experiments were performed using spatial reference points with known positions. The experimental results show that the proposed improved alignment algorithm has errors bounded within 3 mm, which is highly accurate.

“…This game system aims at providing simple illustrations on paper media, using 3D models on portable systems. Larrarte and Alban [33] explored visual interaction in mobile augmented reality. The game content simultaneously displays the real environment around the players and virtual objects in augmented reality, which can extract depth and marks from medical objects.…”

Medical operations(MOs) are essential in healthcare, and they are also a big concept that includes various operations during the perioperative period. Traditional operation exposes its limitations during the perioperative period, reflected in medical training, surgical preparation, and postoperative rehabilitation. Serious Games for Medical Operation (SGMO) offer new ways and complementary solutions to support MOs. Methods: As a review, this paper analyzes the development of SGMO and considers various aspects of the SGMO, such as interface, functions, and technologies. Results and conclusion: By combining MO and serious games' characteristics, the paper classifies SGMO and analyzes their features and functions for different groups of users and at various stages of the perioperative period (before, during, and after an MO). Interactive technologies used in SGMO are presented from a visual, haptic, and auditory perspective. Significance: This paper reviews the development of SGMO, summarizes its functions and technologies. Besides, it presents representative products and suggests future research directions.
