Pros
Makes specialized training easier
With holograms, educators and experts can explain crucial subjects and perform experiments right before their learners. For instance, medical students can be walked through surgical procedures without actually having to be in one classroom, that too live, and in person.
AI holograms can also be tapped into to showcase extremely complex subjects and experiments, which learners can also return to later, from the comfort of their homes. Thus, this makes the entire process extremely interactive.
Brings together learners who are in different locations
AI holograms can completely do away with geographical boundaries by simulating face-to-face interactions. For example, students from different countries and in different classrooms can get together to learn more about their diverse cultures through these live projections and perhaps, even 3D show-and-tells! Students get the feeling that they are there, with them, thus creating an immersive and memorable learning experience.
Makes history come alive
Want your learners to get a better understanding of the events that spurred the French Revolution? Or perhaps, experience the Globe Theatre of the Elizabethan era while sitting in the classroom? Holographic technology can make this possible. Through this, learners can not only witness historic events but also interact with the environment when coupled with spatial sound technology.
Makes multiple lectures possible
With holograms, educators can teach multiple classrooms simultaneously. This can prove to be a boon in underserved regions of developing countries that don’t have an adequate number of schools. Universities too, can expand their global reach and play a huge role in eradicating inequalities pertaining to access to education by adopting holographic technologies in the near future.
It does not require special glasses to view and can be viewed from any angle.
Unlike VR headsets of AR glasses, holograms can be seen without the need of any additional devices as the human eye is capable of viewing them as they are. Holograms are also not restricted by classroom layouts as unlike AR images, they can be seen from any angle in the classroom.
Useful for Libraries and Museums
Looking up reference materials and information through an holographic interface while allowing visitors to interact with normally restricted exhibits to enhance the learning experience
Cons
High production and development costs for better quality holograms or traditional 2D images
Developing a high quality and stable image will require a considerable investment and is unlikely to be able to made available to all teachers due to availability and costs. A bad quality holographic image could affect the learning experience (comparable to Zoom session has delay and lag)
Emerging form of technology, not ready for mass commercial use
As covered in the Mobile Hologram section, most advancements in Holographic technology by companies are still within the R&D phase and options are limited for those who wish to implement them on a wide scale.
It is time consuming to construct images using 3D holograms.
Proper equipment such as high resolution cameras, proper lighting conditions and room layout will influence how the 3D image appears to the audience. As the intention is to create a near replica, considerable amount of effort will be required to ensure the quality of the image and sound. For teaching materials where holographic images might be displayed, special software might be required to render the 3D models which involves time and costs. Unlike images which can easily be shared, created and retrieved online, holographic images are proprietary and custom made.
