Unfortunately, metadata are usually stored in separate files in custom-made data formats, which reduces accessibility even for experts and makes the data inaccessible for non-experts. There is an ever increasing amount of video data sets which comprise additional metadata, such as object labels, tagged events, or gaze data. In this paper we describe a unique prototype application developed over the Australian GrangeNet broadband research network, which combines videoconferencing over access grid nodes with collaborative, real-time sharing of an application which enables the indexing, browsing, annotation and discussion of video content between multiple groups at remote locations. But it is extremely challenging technically and demands significant bandwidth, particularly for video documents. The ability to do this collaboratively and in real time during group discussions is of great interest to the educational, medical, scientific, cultural, defense and media communities. When a user retrieves a document, they can also download the annotations attached to it from an annotation server to view their peer's opinions and perspectives on the particular document or to add, edit or update their own annotations. By annotations we mean subjective comments, notes, explanations or external remarks that can be attached to a document or a selected part of a document without actually modifying the document. Besides, the AR icon is added to the participants icon to see who has activated AR mode.A number of research groups and software companies have developed digital annotation tools for textual documents, web pages, images, audio and video resources. Your annotation color matches your participant tile color to help users identify who is annotating. To place a sticky annotation, just tap the appropriate position on the screen. If the scan was successful, dots will highlight the area where you can now place a sticky annotation.Ĥ. To do so, follow the instructions on the screen.Ģ. ![]() First, scan the environment of the object you want to annotate. To place a sticky annotation in AR mode, follow these steps:ġ. If the device you are using is not supporting AR mode, the AR icon is crossed out. NOTE: Sticky annotations in AR mode are available for all devices supporting ARKit or ARCore. It will turn from black and white to color. To activate AR mode in a video call, tap the AR icon in the top left corner. To learn how to start video sharing, read here. Video sharing must be activated to set annotations. NOTE: Your drawing color matches your participant tile color to help users identify who is drawing.īy using AR mode you can place sticky annotations to highlight a specific object while moving the camera of your device. By clicking the trash can, you can delete all previously drawn annotations.By clicking the arrows in the right upper corner, you can undo/redo the last annotation.You can switch to the drawing annotation by tapping the draw icon at the bottom of the screen. When entering the edit mode (2D mode) during a call, the pointer annotation is selected by default. NOTE: The pointer's color matches your participant tile color to help users identify who is pointing. ![]()
