# Opportunities and Challenges of Smartglass-Assisted Interactive Telementoring
## 6 Conclusions  
In this paper, we explored XR concepts of remote collaboration and telementoring focusing on the use of smartglasses. To elicit requirements and the trends of telementoring, we reviewed recent studies from 2015 to 2021. Based on the literature review, we defined what three characteristics the SAIT (smartglass-assisted interactive telementoring) features. To elaborate on this specialized use case of telementoring, we presented five illustrative and descriptive scenarios including paramedics, maintenance, culinary education and certification, hardware engineers, and foreigner navigation. Lastly, we identified opportunities, technical and societal challenges to overcome for successfully realizing the SAIT.  
Our current approach has limitations and shortcomings that deserve further study. First, our approach was not the systematic review or meta-review in nature as other researchers have explored [10, 11]. We investigated relevant studies mostly using commercially available smartglasses, which might have missed custom-designed prototypical approaches presented earlier than 2015. Indeed, as it turns out, our approach only covered high-fidelity smartglasses with stable hardware design, but there could be low-fidelity approaches of surgical telementoring applications [10, 11] that we have not included in our analysis. Another limitation of our work is that our newly proposed SAIT scenarios are situated outdoor and involves multiple simultaneous user interactions. This complexity calls for carefully orchestrated security and privacy measures in wearable computing as well as XR settings which we were not able to cover due to the scope of the paper.  
Nonetheless, we expect our proposed SAIT has its merits to support various telementoring applications beyond medical and surgical telementoring, while harmoniously fostering cooperation using the smart devices of mentors and mentees at different scales for collocated, distributed, and remote collaboration.
