Final answer:
The obstacle in using VR technology is insufficient bandwidth and data transmission infrastructure for the required data transmissions. High-speed internet is crucial for VR, and expansion of internet service is needed, particularly in underserved areas.
Step-by-step explanation:
One major obstacle to using VR technology is that not enough bandwidth and data transmission infrastructures are currently available to carry out the data transmissions needed for a virtual reality environment. While technology has significantly evolved, impacting various aspects of our daily lives, high-speed internet remains a vital component that has not yet reached all areas equally, leading to digital divides and digital deserts. For VR to become a viable alternative to physical travel, significant investment in upgrading and expanding internet infrastructure is required, especially in rural and low-income urban areas that currently lack access to high-speed internet service.
