System to save personal notes to specific slides while attending a presentation

Saving personal notes related to specific slides during a presentation is not always so comfortable. Slides are often projected on a screen or wall when one is doing a presentation to an audience. Although the main purpose of the presentation is communicating something to the spectators (e.g. financial data, details of a new project or educational notions), it often happens that a spectator is willing to keep their own personal notes about the slide content. Such notes can be written down on paper or on an electronic device (e.g. tablet). If the slide content is not already available to spectators on paper or in electronic format), one problem is that it may not be easy to write down a reference to a specific slide, because, even if slides are numbered, the viewing conditions are not always good enough to be able to read small texts, because of observer distance, image focusing and room lighting. So, a

way to create a reliable link to a specific slide into the personal note would be useful.

While prior arts exist in terms of taking notes electronically (simulated notepad, audio/video recording, etc), the problem of creation of a reference to a specific slide is not specifically addressed.

Our proposal is that a notepad application for a mobile device is equipped to use the camera to get a reference of the slide currently shown. In particular, the owner points the camera to the projected image for a few seconds and the application identifies a portion of the screen where a time-variant dot-based code (similar to a dynamic QR code) is continuously shown. This dot pattern encodes a few bits of information, including a slide number and possibly a document number. The code is generated by the software projecting the slide, in accordance with the slide number. The presentation software is modified so to include an option of generating and showing a dynamic dot-code in a portion of the slide. Because we do not want to steal slide space to actual content and at the same time guarantee good readability of the code in difficult viewing conditions, the dot pattern will...
