Technical bottlenecks in the field of AR according to Roger’s theory.

Technical Bottlenecks	Description
Compatibility with social practices	Wearable devices such as Google Glass may create privacy issues.
Complexity (user-friendliness or learning)	AR is easy to learn by novice surgeons and can increase the learning curve.
Lack of accuracy in alignment	Modern DL algorithms such as deep transfer learning and supervised and unsupervised learning are used to tackle the issues in real-to-virtual world mapping. Lighting conditions can be adjusted for better alignment.
Trialability to general public	Easily deployed but may be expensive to test in several regions simultaneously.
