While it seems like the workbench would be "inferior" to a fully-immersive virtual reality system, it does possess various advantages:
- It does not create the same issues of "motion sickness" that other virtual reality systems can cause, since it's stationary.
- Can thus be used for longer stretches of time
- Offers a much higher level of detailed interaction with the virtual image
- Can allow multiple people to interact on one image at once
- Is overall more ideal for a medical setting
