By immersing patients in calming VR environments, therapists can reduce their perception of pain and provide mental relief. VR has also shown promise in treating mental health conditions such as PTSD and anxiety through exposure therapy.
AR in Surgery: AR is being used in real-time surgery assistance. Surgeons can wear AR glasses that display 3D images of the patient’s anatomy, helping them navigate complex structures and reducing the risk of errors. For example, during spinal surgery, AR can overlay the patient’s anatomy on the surgical site, assisting surgeons with precise incisions.
AR and VR are advancing healthcare by making procedures safer, enhancing patient care, and expanding the possibilities of medical treatment.
5. Retail and E-Commerce: A New Shopping Experience
AR and VR are reshaping the retail industry by enhancing the online shopping experience and enabling consumers to make better purchasing decisions.
