When it comes to Virtual Reality (VR) the exposure tends to fall into the gaming world, but there are major medical advances taking place when it comes to VR treatments and training.
One of the most interesting VR treatments I came across was for treating glossophobia (fear of public speaking) where the speaker can adjust the size of the audience and the room. There is a whole world of VRGET (Virtual Reality Graded Exposure Treatment) where a range of mental illnesses are treated such as PTSD.
There are also advances in VR training for medical students where it is estimated that students will become more efficient and precise without the use of cadavers.
When technology meets medicine, there is so much that can be done for the human race, hopefully advancing medicine so that it can serve more people for less. The adverse of this relationship can be seen in a documentary "The Inventor" where an innovative blood-testing company was built on a lie.
