User augmented reality for camera-enabled mobile devices

Abstract: Apparatus and methods are described for providing a user augmented reality (UAR) service for a camera-enabled mobile device, so that a user of such mobile device can use the mobile device to obtain meta data regarding one or more images/video that are captured with such device. The meta data is interactive and allows the user to obtain additional information or specific types of information, such as information that will aid the user in making a decision regarding the identified objects or selectable action options that can be used to initiate actions with respect to the identified objects.

User Interaction in Augmented Reality

Abstract: Techniques for user-interaction in augmented reality are described. In one example, a direct user-interaction method comprises displaying a 3D augmented reality environment having a virtual object and a real first and second object controlled by a user, tracking the position of the objects in 3D using camera images, displaying the virtual object on the first object from the user's viewpoint, and enabling interaction between the second object and the virtual object when the first and second objects are touching. In another example, an augmented reality system comprises a display device that shows an augmented reality environment having a virtual object and a real user's hand, a depth camera that captures depth images of the hand, and a processor. The processor receives the images, tracks the hand pose in six degrees-of-freedom, and enables interaction between the hand and the virtual object.

Augmented reality applications in manufacturing: a survey

Abstract: Augmented reality (AR) is a novel human–machine interaction that overlays virtual computer-generated information on a real world environment. It has found good potential applications in many fields, such as military training, surgery, entertainment, maintenance, assembly, product design and other manufacturing operations in the last ten years. This paper provides a comprehensive survey of developed and demonstrated AR applications in manufacturing activities. The intention of this survey is to provide researchers, students, and engineers, who use or plan to use AR as a tool in manufacturing research, a useful insight on the state-of-the-art AR applications and developments.

Development and behavioral pattern analysis of a mobile guide system with augmented reality for painting appreciation instruction in an art museum

Abstract: A mobile guide system that integrates art appreciation instruction with augmented reality (AR) was designed as an auxiliary tool for painting appreciation, and the learning performance of three groups of visiting participants was explored: AR-guided, audio-guided, and nonguided (ie, without carrying auxiliary devices) The participants were 135 college students, and a quasi-experimental research design was employed Several learning performance factors of the museum visitors aided with different guided modes were evaluated, including their learning effectiveness, flow experience, the amount of time spent focusing on the paintings, behavioral patterns, and attitude of using the guide systems The results showed that compared to the audio- and nonguided participants, the AR guide effectively enhanced visitors' learning effectiveness, promoted their flow experience, and extended the amount of time the visitors spent focusing on the paintings In addition, the visitors' behavioral patterns were dependent upon the guided mode that they used; the visitors who were the most engaged in the gallery experience were those who were using the AR guide Most of the visitors using the mobile AR-guide system elicited positive responses and acceptance attitudes
