Interconnection network with a shared whiteboard: Impact of (a)synchronicity on computing power

In this work we study the computational power of graph-based models of distributed computing in which each node additionally has access to a global whiteboard. A node can read the contents of the whiteboard and, when activated, can write one message of O(log n) bits on it. When the protocol terminates, each node computes the output based on the final contents of the whiteboard. We consider several scheduling schemes for nodes, providing a strict ordering of their power in terms of the problems which can be solved with exactly one activation per node. The problems used to separate the models are related to Maximal Independent Set, detection of cycles of length 4, and BFS spanning tree constructions

Supporting collaboration and engagement using a whiteboard-like display

Large interactive display surfaces have the potential to combine the simplicity, spontaneity and presence of a conventional whiteboard with the convenience, clarity, and archiving and retrieval capabilities of a computer display. Recent developments in display projection and large surface digitising have brought the cost of such displays to a level where they can be utilised to support a range of everyday activities. This paper describes the LIDS (Large Interactive Display Surfaces) project, recently commenced at the University of Waikato. LIDS focuses on the use of low-cost whiteboard-like shared interactive displays, and is exploring whiteboard metaphors and lightweight interaction techniques to support group collaboration and engagement. Three closely related application areas are being studied: (i) support for single and multiple site meetings and informal discussions, (ii) the use of such displays in teaching, and (iii) their use in personal information management

Enhanced Whiteboard Capture for Chat

A system may provide a mechanism for chat and collaboration services, whereby: 1) The system may allow a user of a chat or collaboration service to activate a specialized flow for uploading a whiteboard image, which uploaded image may then be subject to further processes of the system pertaining to whiteboard images. 2) The system may allow a user to tag or otherwise indicate images uploaded to a chat or collaboration service as being whiteboard images, subsequent to those images having been uploaded, which images may then be subject to further processes of the system pertaining to whiteboard images. 3) The system may automatically detect an image as being a whiteboard image, upon uploading of the image to a chat or collaboration service, or subsequent to uploading of the image to the chat or collaboration service, employing techniques of computer vision, AI+ML, and the like, which images may then be subject to further processes of the system pertaining to whiteboard images. 4) The system may perform processes upon whiteboard images to enhance them, such as by: a) removing glare or reflections, b) straightening, strengthening, darkening, or otherwise repairing lines or generally improving their legibility, c) removing irrelevant or sensitive content adjacent to the primary content of the whiteboard image and captured inadvertently along with the primary content, and so on. 5) The system may further analyze and parse the content of uploaded whiteboard images, in order to determine semantic information and produce metadata and other data characterizing the content of the image for consumption by subsequent analysis, indexing, search, and other processes. 6) The system may determine the identity of a specific whiteboard from which a whiteboard image was captured, along with the identity of a meeting room, conference room, or other venue containing the specific whiteboard, along with locational coordinates or other locational data associated with the whiteboard. 7) The system may, utilizing semantic information, metadata, and other data characterizing the content of whiteboard images, perform processes upon whiteboard images to augment them, such as by: a) adding interactive links to definitions within a glossary for acronyms or other terms contained within images, b) adding interactive links to related documents or other related whiteboard images, c) expanding shorthand codes for elements or components or replacing such shorthand representations with more complete representations, and so on. 8) The system may, utilizing a structured representation of the content of a whiteboard image and the elements contained therein, that is produced during parsing of the whiteboard image, along with semantic information, metadata, and other data characterizing the content of the whiteboard image, re-render a whiteboard image to produce a more professional and polished representation of its original content. 9) The system may assess a whiteboard image, by analyzing the semantic information, metadata, and other data characterizing the content of the whiteboard image that is produced during parsing of the whiteboard image, in order to determine whether a whiteboard containing the image should be erased because of a risk of the content of the whiteboard image revealing confidential or sensitive information, were the content to be left on the associated whiteboard for an extended period of time, and the system may consequently recommend erasure of a whiteboard in such cases. The system may analyze a whiteboard image, as part of or subsequent to parsing of the whiteboard image, in order to determine the identities of one or more authors to whom the whiteboard image may be attributed

WB-Cleaner Si Penghapus Permanent Marker

The one of Effective instructional media in order to support the success of the learning process isthe board or (white boards). But in use, whiteboard can hinder the effectiveness of the learning process when the slates used are dirty due to the rest of the previous posts. This is because the eraser which used is not really able to delete the post until the whiteboard clean as new. Generally, the eraser made of fabric designed with wood or plastic and does not remove the whiteboard until completely clean, so the whiteboard that has a very dirty usually would replaced with a new one, but if seen in terms of the physical is still good , but it is no longer effective if used continue, so inevitably the whiteboard must be replaced. But if there is a cleaner that can clean the whole lifetime of the slates may be longer and better teaching effectiveness and cost savings in the field of education expenses to buy a new whiteboard. But until now there is no specific product that is designed to clean up the remnants of markers on a whiteboard markers either regular or permanent markers. Therefore, for a more durable whiteboard, we provide a solution to make The Whiteboard cleaner liquid-based natural that we refer to as "WB-Cleaner". This product is designed to remove dirty whiteboard that has been caused by the use of regular markers and permanent markers
