In the next sections, we propose an approach to design AR as the specifications of the following: What are the objectives of the medical procedure?What is the optimal support (i.e., data, information, and knowledge) helping to reach this objective?What is the optimal representation mode to perceive this support?
Variability of the penetration of particles through facemasks

The WHO defines medical masks as surgical or procedure masks that are flat or pleated. Unlike N95 FFRs and surgical masks that employ straps that fasten around the head to ensure a tight fit to the face, procedure masks often have earloops (World Health Organization 2020). Due to the short supply of surgical masks, procedure masks are more commonly used by the general public, so they were examined in this study. The primary purpose for which medical procedure masks were originally intended is to reduce the spread of bioaerosols from the wearer to others (a patient) from the aerosol exhaled by the wearer (He et al. 2013). Previous studies have reported that surgical and procedure masks provided lower protection than N95 FFRs when challenged with aerosols containing pathogens (Grinshpun et al. 2009; C.C. Chen and Willeke 1992), but a recent study shows that the ASTM-certified medical masks that fasten using ties around the head rather than with earloops can provide a reasonable degree of protection, while those with earloops were markedly inferior (Sickbert-Bennett et al. 2020). One comparison found no significant difference in the degree of protection given by N95 FFRs and surgical masks from the influenza virus (Johnson et al. 2009). Many of the masks available to the general public are pleated procedure masks formed from multiple layers of non-woven polymeric materials, often carrying no designation as to whether these masks satisfy ASTM or any other standards. They usually have earloops rather than the head ties that are employed on surgical masks.

Figure 11 says it is a medical procedure performed to discover, diagnose, or monitor disease processes and susceptibility and decide on a treatment plan. Tests in the medical field can help find a problem, diagnose it, and arrange treatment, and they can see if treatment is working or monitor status over time. A doctor may prescribe these tests as a routine assessment to screen for specific illnesses and disorders or monitor health. Overall percentage of inbound tourism
An integrated haptic-enabled virtual reality system for orthognathic surgery planning

Orthognathic surgery (OGS) is a medical procedure aiming to correct jaw miss-alignment and dentofacial deformities (Posnick 2013). It requires a precise pre-surgical planning to generate the surgical information needed in the operating room and achieve the desired surgical outcomes. Traditionally, the conventional OGS planning process comprises four steps: Clinical facial analysis. Conducted on the patient’s frontal and lateral face photographs. By means of the facial analysis, the surgeon determines a preliminary diagnosis and treatment, i.e. orthodontic or surgical treatment.Cephalometric analysis. To confirm the previous diagnosis and treatment, a cephalometric analysis is carried out on a lateral patient’s skull radiography. The cephalometric values are compared with pre-established standards to determine a final diagnosis and treatment.Model surgery. When a surgical treatment is needed, model surgery allows surgeons to correct the maxillary misalignment by using the patient’s dental cast models, which are mounted on an articulator to simulate the patient's maxillary and mandibular position. On the articulator, the dental casts are manually segmented and repositioned to achieve the desired patient’s occlusion.Surgical template generation. Once the desired maxillary position is obtained, the new patient’s occlusion is recorded manually on an acrylic surgical template (also known as wafer), enabling surgeons to transfer the surgical planning outcomes to the operating room.
