Abstract: An interactive method and system to support and facilitate note-taking tasks in a variety of settings, primarily, though not exclusively, in real time. In one embodiment, the system user uses a stylus device and display to enter notes in the form of handwritten strokes that are stored and correlated with an address, such as a time provided by a system clock. Notes are collected in a data structure represented by a spatial region on the display called an address, or time, zone that is created when the user enters a gesture requesting an address from the system. All notes entered in a particular time zone region in the display area are stored in a portion of the data structure correlated with the time associated with that time zone region, and, while time zones are created in sequential time order, notes are may be entered in time zones in any sequence and still be correlated with that time zone. An additional feature provides for designating a portion of the user's notes as a key word, which can then be associated with other time zones to connect key words with times and notes. The strokes entered and designated as a key word are assigned a unique, system-recognizable identifier. A data structure stores the strokes of the key word, its location in the display area and the times zones it is associated with. A well-designed user interface provides workspaces for creating and using time zones and for easily displaying and using key words.

Abstract: A method for providing a flexible method for applying computationally significant association information in graphical input systems to information data using unrecognized visual information is disclosed. A method is provided to mark and index user-produced information (82) with special information designators called key objects (84,88,92) which can later be used as access mechanisms into the user-produced notes, without recognition of the notes. Visually recognizable, but computationally unrecognized, image segments are designated key objects. A key object is assigned a unique identifier that is computationally distinguishable from other key object identifiers. Key objects are associated with other data objects by attaching the key object identifier to other data objects in a data structure. A key object is easily created and reused, and provides a flexible and powerful indexing tool into graphically significant information without requiring the use of expensive or sophisticated recognition algorithms.

Abstract: An interactive method and system are disclosed for supporting and facilitating note-taking tasks in a variety of settings, primarily, though not exclusively, in real time. In one embodiment, the system user uses a stylus device and display to enter notes in the form of handwritten strokes that are stored and correlated with an address, such as a time provided by a system clock. The system user must specify the request of an address from the system, and in this manner, the specification of an address such as time is entirely under the system user's control. Notes are collected in a data structure represented by a spatial region on the display called an address. or time, zone that is created when the user enters a gesture requesting an address from the system. All notes entered in a particular time zone region in the display area are stored in a portion of the data structure correlated with the time associated with that time zone region, and, while time zones are created in sequential time order, notes can be entered in time zones in any sequence. An additional feature is provided for designating a portion of the user's notes as an information designator. A common example of an information designator is a key word, but the information designator function is designed for any task requiring the identification, tracking, and retrieval of specific information contained in the notes. In one embodiment, the method and system avoid recognition of the strokes entered and designated as an information designator by assigning a unique, system-recognizable identifier to each information designator so as to facilitate later access to time values via the unique identifier. An information designator data structure stores both the strokes and the unique identifier of an information designator. A well-designed user interface provides workspaces for creating and using time zones and for easily displaying and using information designators.

Abstract: A method and system are disclosed for searching and matching gesture-based data such as handwriting without performing a recognition process on the handwritten gesture data to convert it to a standard computer-coded form. Target data (16) collected as sample data points (20,22) of spatial coordinates over time are concatenated into a single target gesture sequence of sample data points. The sample data points comprising the gesture-based data structure to be searched (the corpus) are grouped into corpus gesture sequences for matching against the target gesture sequence. Matching may be done by any suitable method, and a novel signal comparison technique based on dynamic time warping concepts is illustrated. The result of the matching is a list of the locations of the matching corpus gesture sequences in the corpus, which in turn may be used for further processing, such as the display of an image of the matching corpus gestures for a system user. The ability to determine the existence and location of a gesture in the corpus that matches a target gesture (10) is the basis for performing a variety of additional functions, such as a "find and replace" function and the ability to use gestures as keywords to index a gesture-based data structure without performing recognition on either the keyword gestures or the gesture-based data structure. The technique is suitable for inclusion in any system that accepts gesture-based data, such as a personal digital assistant (PDA) or other pen-based computing device.

Abstract: An interactive processor-controlled system for entering and storing user information about an event that is being concurrently recorded in real time correlates the user information to user-requested addresses, such as time values stored with the recorded signals. The system includes a recording device for producing signals indicating recorded event data that includes periodic addresses, each of which indicates a portion of the recorded signals. An address source, such as a clock, is connected for providing address values to both the processor and the recording device. Using a pen-based user interface in one embodiment of the system, the system user specifically requests an address value in order to correlate user information to the signals being concurrently recorded. In response to a request for an address, the system establishes a spatial region on the display, called a time zone, into which the system user may enter information, in the form of handwritten strokes, about the event. All information entered into a time zone is stored and correlated with the address value represented by the time zone, in effect creating a log of the recorded event that may be used to access the portions of the recorded signals. While time zones are created by the user in sequential time order, information can be entered in to time zones in any sequence, thereby facilitating editing and annotation of previously-entered information. The ability to correlate the recorded signals to keywords designated in the user-supplied information is also provided.
