Ubiquitous manufacturing provides users with advanced control over the physical manufacturing environment. Ubiquitous augmented reality (UAR) interface enables direct manipulation in an environment containing smart objects. This paper describes a framework for implementing augmented reality (AR) in a ubiquitous manufacturing environment. The proposed system makes use of real-time data captured from client machines to update and manage AR contents. Ubiquitous augmented reality is utilized as a user interface for the client users to receive instructions and guidance from the system and to update the system on task parameters. A review of related work, and the framework, methodology, and implementation of the proposed system, and a case study are presented in this paper to demonstrate the UAR content delivery and update.
