Apple is reportedly working (experimenting) on including an air conditioning system for its virtual reality (VR) headset. The company has long been rumoured to be working on new types of devices pertaining to virtual reality (VR) and augmented reality (AR). While AR headset or AR glasses need to be compact, easy to wear, and non-obtrusive, VR headsets are and can be large, so including a mini air conditioning system inside a VR headset does not sound crazy at all.
Over the years, Apple CEO Tim Cook has talked several times about the next generation of tech products that will change the industry and he has almost always mentioned augmented reality (AR). He has said that he thinks Augmented Reality (AR) to be “Critically Important” for the company. But apart from just the official or business related comments, he has also shown fondness for AR.
