The described embodiments present a system and method for obtaining a portion of a digital document from a printed version of the document. Locations where a smart pen device interacts with a digital bookclip aligned relative the printed document are identified via coordinate sets. A digital document associated with the printed document and the coordinate sets from the smart pen device and digital bookclip are used to identify locations in the digital documents corresponding to locations in the printed document. Data from the identified locations in the digital documents is retrieved and presented to a user and can then be copied, saved, mailed electronically, and/or printed to a new paper document.

Digital bookclip

An instruction is presented to a user for making a target gesture. The target gesture may be a portion of an exemplary or model symbol. The instruction may be presented in various ways, such as being printed on a writing surface or being played in audio format through a speaker of a smart pen device. A writing gesture made on a writing surface by the user is digitally captured using a smart pen device. The captured writing gesture is compared to the target gesture and feedback is determined based on this comparison. This feedback may indicate the correctness of the user's writing gesture. The feedback may be presented to the user through various means, including through the smart pen device. The comparison may also be used to determine a next instruction for the user to follow.

Multi-modal learning system

In a pen-based computing system, a user-specific smart pen application is created from a template application using customer authoring tools. The template application contains computer program code that is to be executed by a processor of a smart pen. Application content and a representation for printed content are received. The application content, provided by user or customer, defines functional interactions between the printed content representation and a smart pen. The template application is combined with application content to generate a user-specific application comprising instructions for being executed on a processor of a smart pen. The user-specific application is stored on a storage medium.

Customer authoring tools for creating user-generated content for smart pen applications

Embodiments of the invention present a system and method for identifying relationships between different types of data captured by a pen-based computing system, such as a smart pen. The pen-based computing system generates one or more sessions including different types of data that are associated with each other. In one embodiment, the pen-based computing system generates an index file including captured audio data and written data, where the written data is associated with a temporal location of the audio data corresponding to the time the written data was captured. For example, the pen-based computing system applies one or more heuristic processes to the received data to identify relationships between various types of the received data, used to associated different types of data with each other.

Grouping variable media inputs to reflect a user session

Embodiments of the invention present a system and method for controlling audio capture by a smart pen based computing system. An audio capture mechanism that is independent from a gesture capture system is included on the smart pen to control audio capture by one or more microphones included on the smart pen. In one embodiment, the audio capture mechanism comprises a shared function button, such as a power button. For example, a user interaction with the shared function button initiates audio capture by the one or more microphones on the smart pen and a second user interaction with the shared audio function stops audio capture. Alternatively, audio capture is stopped after completion of a predefined time interval after the user interaction with the shared function button.

Quick record function in a smart pen computing system

In a pen-based computing system, multi-modal data is transferred between a paper domain and a digital domain. Data initially generated in the paper domain is captured by a smart pen and a digital file including the captured data is generated. For example, a computing system coupled to the smart pen generates a digital file including the captured data. A paper representation of the digital file is subsequently generated. The digital file can subsequently be modified by editing the paper representation of the digital file using the smart pen. Edits to the paper representation of the digital file are captured by the smart pen and converted to the digital domain where they are used to edit the content of the digital file.

Cyclical creation, transfer and enhancement of multi-modal information between paper and digital domains

In a pen-based computing system, use of paradigms similar to those used with physical paper to organize user generated content captured by a smart pen is disclosed. Data, such as handwriting gestures, is captured by the smart pen and transferred to a digital domain, such as by being transferred to a computing system. Once in the digital domain, the captured content is organized as virtual pages or virtual notebooks. Hence, content captured from various sources, such as different notebooks or different physical pieces of paper, is assembled into a virtual page or virtual notebook. User input or automatic application of rules can be used to assemble the captured content into a virtual page or virtual notebook.

Organization of user generated content captured by a smart pen computing system

In a pen-based computing system, a microphone on the smart pen device records audio to produce audio data and a gesture capture system on the smart pen device records writing gestures to produce writing gesture data. Both the audio data and the writing gesture data include a time component. The audio data and writing gesture data are combined or synchronized according to their time components to create audio ink data. The audio ink data can be uploaded to a computer system attached to the smart pen device and displayed to a user through a user interface. The user makes a selection in the user interface to play the audio ink data, and the audio ink data is played back by animated the captured writing gestures and playing the recorded audio in synchronization.

Animation of audio ink

A system and method for identifying captured written data associated with a writing surface using a pen-based computing system are described. In one embodiment, a series of writing surfaces, such as notebooks, are produced, each including a plurality of pages that have an encoded pattern. In an embodiment, each writing surface is also associated with an identifier recognizable by a smart pen or other data capture device. When the smart pen captures written data from a writing surface, the smart pen determines whether the pen-based computing system includes stored written data previously captured from a writing surface having the same encoded pattern as the writing surface from which written data is currently being captured.

Managing objects with varying and repeated printed positioning information

In a pen-based computing system, a printed version of a document having preexisting content is annotated using a smart pen. The smart pen captures handwriting gestures to obtain an electronic representation of the annotations. The smart pen computing system identifies a digital version of the document having the preexisting content and stores the electronic representation of the annotations in association with the digital document. The smart pen computing system may overlay the electronic representation of the annotations with the preexisting content to provide a digital representation of the annotated document.

Electronic annotation of documents with preexisting content

Systems for removing or attenuating friction and/or click noise generated during writing with a smart pen are disclosed. In a smart pen, the writing cartridge is biased towards a first side of the smart pen internal cavity by a low-force biasing system without affecting writing cartridge movement. For example, the writing cartridge is comprised of a magnetic material and a magnet is embedded into the first side of the smart pen internal cavity to bias the writing cartridge towards the first side. Alternatively, the material comprising the writing cartridge or smart pen internal cavity is modified, reducing friction between the components. As another alternative, a DSP method identifies analyzes one or more parameters of received audio data to differentiate click noise from audio data, and may receive data from a movement sensor indicating when the writing cartridge has moved to reduce power consumption for identifying click noise.
