Augmented Reality has been the subject of scientific and engineering research for decades but has only recently been brought to the attention of wider audiences. As the concept is broad, it is easily confused with other new and emerging technologies with which it shares attributes.
2020欧洲杯网投The AREA has compiled the following list of key AR terms and their definitions to help enterprises understand what distinguishes AR from other technologies and to provide a helpful reference when reading about AR-specific tools and concepts.
Augmented Reality refers to any technology that “augments” the user’s visual (and in some case auditory) perception of their environment. Typically, digital information is superimposed over a natural, existing environment. Information is tailored to the user’s physical position as well as the context of the task, thereby helping the user to solve the problem and complete the task.
2020欧洲杯网投Assistive Reality is technique that connects people with data required to perform tasks by placing that data directly within their field of view in a user-centric manner. Relevant information is presented to the user overlaid on his/her field of view (FOV) in user-centric manner. The information follows the user’s movements and does not have any spatial relationship with the surrounding environment.
Allocentric Space (also known as object-centric space2020欧洲杯网投) is one of two reference systems used to map the location of digital content in an AR application. It uses the object of interest as the reference point. The other reference system, Egocentric Space, uses the user’s body or head as the reference point.
