Abstract: To employ presence-based history information in conjunction with a notebook application, presence information for one or more users associated with a notebook application is determined from a variety of presence services. One or more interactions of the users are tracked in conjunction with a location within the notebook to record history information associated with the one or more users. The history information may be presented to the users through a user interface in conjunction with a location within the notebook application or through a separate user interface. The presented history information may include the recorded history information and statistical information based on the recorded history information. The users may interact with the user interface to employ the presented presence-based history information in conjunction with contents of the notebook application. For example, replay of user interactions in conjunction with a location within the notebook application may be enabled.

Abstract: A note-capture application is disclosed that allows notes to be displayed on the lock screen. In one embodiment, a note-capture application can be invoked when a mobile device is in an above-lock state. Note data can be captured using the note-capture application, and the captured data can be persistently displayed on the lock screen. A user can perform a unique gesture from the lock screen to invoke the note-capture application. In another embodiment, multiple input modes can be available for note data capture. For example, voice data, text data, camera data, etc. can all be used to capture notes for display on the lock screen.

Abstract: Application functionality is separated into platform neutral components and platform specific components. An application model component defines the core logic of the application and includes interaction models for handling user input that is platform neutral and may be used across platforms. An application host component includes functionality for a specific platform but may be reused across different applications on the same platform (e.g. how to draw on a specific platform). An application user interface component includes functionality (e.g. specific UI for an application) that is platform specific and application specific. Platform neutral Application Programming Interfaces (APIs) are used by the developer to abstract functionality of the application such that the platform neutral code is portable across different platforms. The communication between the platform specific components and platform neutral components uses thread and memory isolation similar to a client-server architecture.

Abstract: User presence is detected in a notebook that includes multiple different documents. The user identity and location within the notebook can be displayed to other users to facilitate collaboration.

Abstract: Architecture for emphasizing changes in collaborative or shared documents. A user can now quickly see what content was changed (hence, unread content) since the last time the user viewed the document or page. A tool automatically tracks and annotates the new content and author of the content for collaboration users. The architecture provides author highlighting on a page or document, which is turned on automatically when the user goes to the page or document. Widgets are displayed in association with the unread content that indicate which user authored all or portions of new unread content. Synchronization of the content update document content so that other users can readily see what is new and the author. A master file is created that stores the emphasis information and associated author information. The file can be stored at any location that is accessibly by the collaborative clients.

Abstract: Calculations within a text editor may be provided. First, a text string may be received within the text editor. The received text string may be configured to be displayed on a display by the text editor. The text string may comprise information entered by a user into the text editor. The information may include equation text and language text associated with the equation text. Next, the text string may be parsed to detect an equation within the equation text in the text string. At least one calculation indicated by the detected equation may be performed to produce a result. The result may then be displayed.
