Heads Up Display. A Technology that has been implemented for many years on figters jet cockpit will be more popular than ever before.
This technology on of most important part of wearable tech such as helmet, glasses, cars front dashboard glass, etc (with augmented reality software inserted) and internet of things era. There will be no wearable tech without this, as a software part.
I predict this kinda stuff will massively entering the market within 5-10 years ahead. Base on my observation and instict, google glass is the only market- test product that will be followed by heads up display penetration into the market.
Will you ready for this?
