It looks like Apple is interested in developing some type of virtual reality head-mounted display or projection system, after new job listings appeared on the company's website. Specifically, there is a need for Optical Display Engineers, Sr. Display Software Engineers, and other roles pointing towards virtual reality.
Considering VR is a booming business, and has great future potential, it shouldn't be surprising if Apple wants to begin seriously developing its own product. In 2014, Apple started recruiting employees to develop "virtual reality experiences," including specialists in augmented reality and 3D graphics.
Microsoft, Facebook, Razer, Steam, and other major companies are throwing down in the augmented reality and VR markets, so Apple will have some competition to deal with in the future. However, Apple has the time and resources to make sure it is able to launch a large-scale development of VR hardware for consumers.
