Human augmentation technology can be placed into 3 categories based on its function: replicating, supplementing or exceeding human ability.
The first aims to replicate and/or restore abilities achievable by a typical person. This is common in the medical field where pacemakers, prosthetics and wearable devices have been advancing for decades.
Supplementing human ability refers to devices that artificially aid one’s strength, intelligence, sight or any other ability beyond normal limits. In construction, these types of wearable devices are being utilised to help reduce strain and fatigue for users – enabling contractors to tackle health and safety issues.
Human augmentations that help exceed human ability are those which allow us to things we wouldn't normally be able to do - like fly, breathe underwater, superhuman sensory enhancement, etc. An example of this is Brain-Computer Interfaces (BCIs) - a field that has grown rapidly the past few decades. While largely conceptual, BCIs are interfaces that allow an individual to interact with a computer or machine using only their mind.
