Augmented reality is one of the emerging technologies continually developing and making its way in the education sector. It is proved from different studies that augmented reality in education helps to improve the overall learning process, learning inspirations as well as its advantages through greater engagement level of students. Though it's being introduced still there are different types of obstacles being faced in the learning process in the way of using this technology. The acceptance of this technology by the students and teachers is very much important so training in this way helps a lot for the viability of AR apps, generating 3D models and making an overall environment and setting of augmented reality.

Augmented reality works on three principles like combining the real and virtual world together, making everything interactive with the help of 3D models. Augmented reality in education has a prominent place in different subjects like biology, chemistry, physics, history, marketing and many more. This technology is being used in all the education levels like childhood, primary, secondary, high school, colleges, and universities. It helps in both formal and informal learning. AR is also useful in this way that it increases student interest in the learning process and improves student performance due to the highly interactive learning process. It is making a new way to develop new learning experiences. The one another important advantage is that it is very useful in developing different skills like critical thinking, problem-solving and effective communication.

Now Let's discuss some of the main obstacles or challenges in the learning process;

Usability

One of the main obstacles is usability problems. It is reported that usually the students and teachers find AR complicated and difficult to use in terms of technicalities in AR apps and other 3D models. Due to these complexities, the students get distracted in the overall learning process. So, to solve this problem one there should be a well-designed guideline to manage all these complexities.

The complicated process of AR apps development

The development and functioning of AR apps is actually a complicated and technical process that needs to have an instructor for proper implementation so adding computer experts, technical experts in the learning process make the overall process very difficult to adopt in an easy way.

3D modeling

This is the very important and basic feature of creating virtual content through 3D modeling in AR apps but it is also considered among=d the main obstacles of implementing AR in education because teachers and experts find it difficult to handle and create such virtual content.

Users experience

As augmented reality combines virtual reality with the real world so can't create the immense effects as expected by users which is the main obstacle in terms of unsatisfying user experience at every level as compared to virtual reality.

Level of acceptance

Though it is being introduced in the education sector but still not widely accepted due to technicalities, cost and complex functionalities which is also a big challenge.

Conclusion

All of these technical problems can be eliminated through proper training and a completely well-designed overall system for best involvement of teachers and students and the best engagement.
