# Opportunities and Challenges of Smartglass-Assisted Interactive Telementoring
## 5 Opportunities and Challenges of SAIT
### Technical and Societal Challenges  
For our presented SAIT to be successful in XR telementoring, there are many technical as well as societal challenges to overcome. Many XR industry experts also have identified urgent areas of improvement [4] as shown in Figure 11.  
Figure 10: An illustration of SAIT for foreigner navigation scenario. Since the SAIT requires the use of smartglasses on mentors and mentees, various challenges of smartglasses are identified and being improved upon [48, 49]. For example, to support the SAIT on everyday occasions, the weight of the HMD should be lighter. To provide a clear and crisp view captured by the HMD's camera, wider FoV and higher resolution are preferred. Such specifications and performance measures of smartglasses including latency, content reproducibility, repeatability, synchronization, and warnings should be enforced through guidelines and standards. For example, there are international standards for VR and AR in environment safety (IEEE P2048.5), immersive user interface (IEEE P2048.6), eyewear display (IEC TR 63145-1-1:2018), and VR content (ISO/IEC TR 23842:2020), respectively. Furthermore, XR experiences in our scenarios are limited since most informational contents (i.e., live video streams and annotations) are hardly considered as XR contents. Easy to use XR authoring tools for developers and service providers are desirable to provide multiple AR, VR, and XR applications [50] and experiences in the SAIT scenarios. Moreover, establishing sufficient network bandwidth for high-resolution videos is also important to share the view and contents [51] of mentors or mentees without interruptions and delays. As more interaction data between mentors and mentees are accumulated, we can benefit from deep learning approaches [52, 53, 54] that enhance various steps involved in the XR pipeline (i.e., registration, tracking, rendering and interaction, task guidance [55, 56]). There are societal challenges regarding the SAIT. Concerns of involved users' security, safety and privacy issues should be carefully managed. As witnessed in the medical and surgical sectors, use of camera in the operation room is very sensitive and controversial. In most countries, installation of and monitoring with closed-circuit television (CCTV) are strictly prohibited. For such sensitive and intimate scenarios, mentors or mentees could be disallowed to use smartglasses at all. There should be a general consensus and regulations among the society about the needs and social acceptance for smartglasses in the discussed SAIT scenarios. Tables 7-11 summarize various technical and societal issues aligned with the areas of improvement [4] in the discussed SAIT scenarios.
