Human augmentation is a thriving research field that aims to amplify human abilities through the development of technological improvements as an integral part of the human body. Human augmentation products may be made for anyone, ranging from healthy users wanting to enhance their human abilities to users who face temporary or permanent disabilities, physical impairments, or perilous situations that oblige them to use these products.

This article attempts to introduce readers to the domain of human augmentation by providing a thorough formulation of the concept and its related terms to develop a more solid structural basis. Additionally, a categorical and dimensional classification of the field was given. Based on these findings, we then proposed a novel framework in the form of a diagrammatic presentation of both classifications, which could enable product designers to better understand and characterize the type of human augmentation product they are designing by determining its location in the diagram. Finally, the proposed framework was evaluated by introducing and classifying several significant human augmentation products most of which have proven to successfully exceed human abilities.
