The problem with wearable headsets is that it can be cumbersome, especially for those who already wear glasses. This means that the added weight of the frame and the glasses could make it too heavy to be used for extended periods of time. However, it seems that Apple could have a rather unique and novel solution to that problem: holographic imaging.
This is according to a recent patent discovered by AppleInsider, where it seems that Apple is exploring holographic imaging that could potentially be used to replace displays used in these types of wearables. It has been suggested that by using holographic imaging instead of more traditional displays, it could address certain functionality issues with such devices.
For example, AppleInsider points at how changes to optical components could affect the size, weight, and cost of the headset. Also, by using more traditional display components, it affects how the headset is designed where components need to be placed further away from the user, which could also apply more pressure to the user’s face, making it uncomfortable to be worn for extended periods of time.
Apple has been rumored to be working on an AR headset for a while now, with some rumors claiming that it could actually launch in 2020 (some say 2021). That being said, this is a patent so whether or not it becomes a reality remains to be seen, but it could be what drives more people to start adopting such devices.
