Title: Reusable notebook and methods thereof

Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a National Stage Application of International Application No. PCT/PCT/EP2021/055677, filed on Mar. 5, 2021, now published as WO/2021/180601, which claims benefit from European patent application No. EP20315036.2, filed on Mar. 9, 2020, the entire contents of which are incorporated herein by reference. 
    
    
     FIELD 
     Aspects of the present disclosure relate generally to apparatuses interacting with a computing system to digitize writing, and specifically to examples of reusable notebooks including coded data printed on a sheet for use with a writing instrument having an imaging device. 
     BACKGROUND 
     Due to rising environmental concerns, prospective consumers seeking to generate handwritten materials may be interested in identifying substitutes for paper to minimize an environmental footprint associated with using paper products. Despite the high levels of consumption and waste associated with using paper, consumers continue to rely upon and prefer paper as a medium for producing handwritten materials due to an availability, simplicity, and/or familiarity of the product. Systems attempting to replace paper products, generally involve complicated methods of capturing photographic images of a written product with an ancillary device (e.g., a camera, smartphone, tablet, etc.) to store the writing prior to erasing the generated content and reutilizing the substitute medium. Providing an apparatus capable of generating handwritten materials and replicating the simplicity of writing on paper, without requiring use of a supplemental device may allow consumers to minimize an environmental impact and retain the benefits of writing on paper (e.g., availability, instantaneity, natural feel, familiarity of pen on paper, etc.) while not requiring additional devices.

       FIG.  1    shows an exemplary writing system  100  that may include writing instrument  110 , reusable notebook  120 , and a computing device  130 . Writing instrument  110  may include body  112  having a longitudinal length defined between proximal end  114  and distal end  116  and may further include one or more grip features  115  disposed along body  112 . In examples, the one or more grip feature  115  may be located adjacent to distal end  116 . In examples, the writing instrument  110  may include additional and/or fewer grip features  115  positioned along various other portions of body  112 . 
     Writing instrument  110  may further include tip  118  at distal end  116  that may be configured to mark e.g., dispense a material such as ink, one or more other components of writing system  100 , such as, for example, reusable notebook  120 . In examples, the writing instrument  110  may include one or more cavities disposed within body  112  for storing the material such as ink, and the cavities may be fluidly coupled to tip  118 . In embodiments, writing instrument  110  may include a pen, a pencil, a marker, a brush, a highlighter, a stylus, a quill, a multifunction pen, etc. As described in further detail herein, writing instrument  110  may be configured to communicatively interact with reusable notebook  120  while dispensing the material thereon. 
     Still referring to  FIG.  1   , writing instrument  110  may include imaging device  117  positioned along body  112 . In examples, imaging device  117  may be located proximate to distal end  116  and adjacent to grip features  115 . In examples, imaging device  117  may be arranged within the body  112 . Imaging device  117  may be an optical system e.g., a sensor, a camera, etc. facing distally toward tip  118 . In examples, the imaging device  117  may be configured to capture photographic images of a working surface  126  of the reusable notebook  120 , positioned adjacent to tip  118  during use of writing instrument  110 . In embodiments, writing instrument  110  may also include a light source (not shown) e.g. positioned along body  112  and located proximate to distal end  116 . The light source may also face distally toward tip  118  thereby being configured to illuminate the working surface  126  of the reusable notebook  120  that in use of the writing instrument  110  is adjacent to tip  118 . In this instance, the light source may be operable to facilitate capturing images with the imaging device  117  by illuminating the working surface  126  of the reusable notebook  120  to be imaged. In embodiments, writing instrument  110  may include a conventional writing apparatus e.g., an off-the-shelf pen or pencil that is provided with “smart” capabilities e.g., image capture capabilities, for example, by securely fastening a separate device e.g., imaging device  117 , a light source, a microphone, etc. via a suitable fastening mechanism e.g., an adhesive, a binding, a ring, a wire, etc. 
     Furthermore, writing instrument  110  may include one or more actuators  119  positioned on the body  112  and located adjacent to the proximal end  114 . The one or more actuators  119  e.g., buttons, switches, knobs, etc. may be configured to control the imaging device  117  of the writing instrument  110 . The actuators  119  may further be configured to control the light source of writing instrument  110  and/or a friction member if present e.g. within the barrel, the tip or a clip of the writing instrument. In examples, the writing instrument  110  may include other hardware components disposed within the body  112 , such as, for example, a microphone for recording audio, a memory configured to store data e.g., image data produced by the imaging device  117  or audible data recorded by a microphone, etc. and/or a communications module e.g., a wireless controller configured to communicate with the reusable notebook  120  and/or the computing device  130 . In examples, the communications module may be configured to utilize Bluetooth® technology, a Wi-Fi network, NFC and/or radio waves frequencies e.g., via an antenna. 
     Still referring to  FIG.  1   , reusable notebook  120  may include one or more sheets  122  coupled to one another by fastening mechanism  124 . Throughout the present description and claims a sheet should be understood as a synthetic plastic paper type able to perform as paper but that is tear-resistant and withstands weather conditions or water. Examples of typical sheet substrates may be made of a polyester such as a high-density polyethylene (HDPE) film, PVC, paper-film. In aspects, the sheet includes a porous working surface and a material of the writing instrument, e.g. ink, comprises solid particles having a particle size greater than a porosity of the porous surface. In the depicted embodiment, reusable notebook  120  includes four of sheets  122  and the fastening mechanism  124  includes a coil binding extending through each of the plurality of sheets  122 . In examples, other number of sheets may be foreseen. In examples, the reusable notebook  120  may include various other suitable fastening mechanisms e.g., an adhesive, a coil, a ring, a staple, a zip bind, a wire, a magnet etc. for securing sheets  122 . In embodiments, the fastening mechanism  124  may be omitted entirely from the reusable notebook  120  such that the sheets  122  may be selectively removable from the reusable notebook  120 . 
     Throughout the present description and claims, a porous surface, also known as porous substrate, is intended to mean writing substrate that contains pores. The porous surface has thus empty spaces or pores that allow external material such as writing ink, to penetrate into the surface or substrate. At the same time, ink compositions suitable or porous surfaces should have a mean diameter in intensity D50 above a specific size, sufficient to prevent those to enter into the spaces or pores of the surface and at the same time, not clogging a pen point. 
     In the depicted example, each of the plurality of sheets  122  may define at least one working surface  126 . In embodiments, the sheets  122  may include a pair of working surfaces  126  on opposing sides of each sheet  122 . In examples, other number of working surfaces may also be foreseen. In examples, the reusable notebook  120  may further include one or more outer covers bound to the plurality of sheets  122  by the same fastening mechanism  124  or by any additional fastening mechanism. For example, the reusable notebook  120  may include a front cover (not shown) positioned relatively over a first sheet  122 A and/or a rear cover (not shown) positioned relatively below a last sheet  122 B. In this instance, the plurality of sheets  122  may be disposed between the outer covers of reusable notebook  120 . In embodiments, one or more aspects of reusable notebook  120  may be provided to other suitable writing surfaces, including, but not limited to, a tablet, a whiteboard, a chalkboard, a legal pad, a calendar, an index/note card, a sticky note, a digital slate, an E-writer, and the like. 
     Still referring to  FIG.  1   , each of the plurality of sheets  122  may include one or more indicia disposed on the working surface  126 , such as, for example, a line, a marking, a label, and/or the like. 
     The sheet  122  includes a porous surface located in the working surface  126 . In examples with multiple working surfaces, each of multiple working surfaces can include a porous surface. In examples, the porous surface is provided by a porous coating. The material, e.g. ink, of the writing instrument  110  comprises solid particles having a particle size greater than a porosity of the porous surface or the porous surface coating when present. For instance, one or more sheets  122  may include a porous surface coating configured to provide a (low porosity) protective layer over the working surface  126 . In examples, the sheet  122  can be porous and/or provide the porous surface e.g., be an uncoated sheet. The sheet can be a paper sheet, e.g., a calcium carbonate paper sheet. 
     Solid particles of the material such as ink can be colorant particles contained in the ink e.g., in an ink being a sol, a gel or a dispersion in some examples. The colorant particles can include one or more dyes and/or one or more pigments or other types of colorants. The ink can include colorant particles including two or more different types of colorants. The particle size can be an average particle size, i.e. arithmetic average, of the solid particles e.g., the colorant particles of the ink of the writing instrument  110 . The particle size of the solid particles e.g., the colorant particles of the ink of the writing instrument  110  can be determined as a diameter of the smallest sphere inscribing a solid particle. The average particle size i.e. arithmetic average, of the solid particles e.g., the colorant particles is the mean diameter in intensity D50. In examples, the average particle size of the solid particles, more specifically the mean diameter in intensity D50 can be higher than about 0.5 µm as determined using dynamic light scattering (DLS), e.g., by using Malvern Mastersizer 3000E. This means that if the average particle size, more specifically the mean diameter in intensity D50, is lower than 0.5 µm, there is a high probability that the particles will penetrate into the sheet. In examples, the mean diameter in intensity D50 may range from 0.50 µm to 20 µm, more specifically form 1 µm to 10 µm. In examples, the solid particles may be particles encapsulating a colorant. The ink may be a thermochromic ink. 
     The porosity of the porous surface or the porous surface coating can be an open cell porosity including a plurality of open pores, i.e., the pores forming the open cell porous surface open towards an ambient environment; closed pores not being open towards an ambient environment can be present but disregarded. The open cell porosity can be defined as a median pore size of the open pores of the porous surface. The pore size can be measured as a diameter of the largest sphere which can be fitted into the pore from a surface of the sheet  122  (e.g., a solid particles being applied to the sheet by the writing instrument). The pore size and average size of the pores may be measured by inverse size-exclusion chromatography. 
     In examples, a surface coating may include, but is not limited to, a specific coating for HP Indigo as the synthetic paper commercially available by Arjobex as Polyart®. Alternative coated synthetic paper sheet may be commercially available as Appvion Appleton Digital™, Parax™ stone paper, RockStock™ stone paper, Nekoosa™ XM, Nekoosa™ OM, HopSyn DL Grade®, Yupo® FPG 80, and other suitable coating materials. As a result of such coatings, written markings  121  produced on sheets  122  by writing instrument  110  may be removable by applying an ancillary device e.g., a wet apparatus such as a wet wipe or a dry eraser against the working surface  126 . 
     Reusable notebook  120  may be communicatively coupled to other components of writing system  100  by, for example, a wireless connection, a wired connection, and the like. In one example, reusable notebook  120  may include a communications module e.g., a wireless controller. The communications module may include electrical circuitry (not shown) for communicating with the writing instrument  110  and/or the computing device  130 . In examples, the communications module may utilize Bluetooth® technology, NFC technology, a Wi-Fi network, and/or radio waves frequencies e.g., via an antenna. Working surface  126  may be an interface of the communications module such as the wireless controller and may include a circuit area of one or more printed electronics or printed code to facilitate communication with writing instrument  110  and/or computing device  130 . 
     Still referring to  FIG.  1   , at least one of the printed electronics or printed code may include an operative control  129  positioned on at least one or each of the plurality of sheets  122 . Operative control  129  may be positioned on the working surface  126  at various suitable locations relative to sheet  122 . In the illustrated example, sheet  122  includes at least one operative control  129  at a top-right corner of working surface  126 . In examples, the working surface  126  may include additional and/or fewer operative controls  129  at various other suitable locations than those shown and described herein without departing from a scope of this disclosure. For example, operative control  129  may be located at a bottom-right corner of working surface  126  such that a user of the writing system  100  may arrive at the operative control  129  upon reaching an end of the sheet  122 . In examples, the sheet  122  may include a plurality of operative controls  129  positioned along a right-side of working surface  126 , such as at a conclusion of one or more lines included on the sheet  122 . In examples, an operative control may be present at the conclusion of each line included on the sheet. 
     Operative control  129  may be selectively actuatable by a user of writing system  100  via one or more methods of interacting with operative control  129 . For example, operative control  129  may be actuated in response to detecting contact of tip  118  and/or a finger of a user against operative control  129 , detecting a marking on operative control  129  by imaging device  117 , and the like. In embodiments, the operative control  129  may include a magnet and writing instrument  110  may include a magnetic sensor e.g., at proximal end  114 , configured to detect the magnet upon alignment of the writing instrument  110  with the reusable notebook  120 , e.g. when the magnetic sensor is arranged at the proximal end of the writing instrument  110 , the magnet would be detected when the proximal end  114  is aligned with the operative control  129  or at least one of the operative controls in circumstances. In embodiments, operative control  129  may include a code and/or tag e.g., RFID identifier and writing instrument  110  may include a receiver e.g., RFID reader configured to read the code upon alignment of writing instrument  110  with operative control  129 . 
     Operative control  129  may be configured to perform one or more functions upon alignment, such as, for example, transmitting a signal from reusable notebook  120  to writing instrument  110 . In examples, the signal transmitted from reusable notebook  120  may be indicative of a command to deliver image data recorded by the imaging device  117  to the computing device  130 . As described in further detail herein, the writing instrument  110  may be configured to record informational data stored along the working surface  126  of one or more of the plurality of sheets  122  via the imaging device  117 . 
     Still referring to  FIG.  1   , reusable notebook  120  may include a power source e.g., a battery configured for wireless charging, solar charging, inductive charging, and/or the like. In embodiments, the power source may be positioned adjacent to a circuit area of the working surface  126 . In embodiments, the reusable notebook  120  may include a port e.g., USB or mini USB plug, Lightning, or any other suitable plug/connection port for coupling the reusable notebook  120  to one or more devices, such as, for example, the computing device  130 , a power supply, and/or the like. 
     Computing device  130  may include a computer system incorporating a one or more hardware components that allow the computing device  130  to receive data e.g., image data, process information e.g., coded data, and/or store data. Illustrative hardware components of computing device  130  may include display  132  and user interface  134 . Display  132  may be configured to generate a visual representation of the data received from writing instrument  110  and/or digital notebook  120 . In examples, computing device  130  may be configured to provide a real-time video display of a written marking  121  produced on the reusable notebook  120  by the writing instrument  110  via display  132 . In examples, the computing device  130  may be configured to permit manipulations e.g., additions to, deletions from, or other edits of the written markings  121  depicted on the display  132 . User interface  134  may be configured to receive one or more user inputs at computing device  130 . In embodiments, computing device  130  may include one or more of a remote station, a server, a cloud storage, an E-writer, etc. In the illustrated embodiment, computing device  130  includes a separate component from the other components of writing system  100 . In embodiments, one or more aspects of computing device  130  may be included within writing instrument  110  and/or reusable notebook  120 . 
     Referring now to  FIGS.  2 - 3   , sheet  122  is depicted with a plurality of cells  128  included on working surface  126 . In examples, one or more of the plurality of cells  128  may include a segment code printed therein defining a printed code. In examples, each cell may contain a segment code printed therein. The segment code may include coded data indicative of one or more characteristics and/or properties of the sheet  122 . In examples, the segment code may include a unique identifier of the particular sheet  122 , i.e., identifying, for example, that the cell  128  including the segment code is located on the particular sheet relative to the plurality of sheets  122  in reusable notebook  120 . In examples, the segment code may include unique directional information of the particular cell  128  relative to the plurality of cells  128  on sheet  122 . Thus, the segment code stored in each of the plurality of cells  128  may correspond to positional information indicative of a particular location of cell  128  along working surface  126  and a particular sheet  122  within reusable notebook  120 . In embodiments, the segment code may be preprinted on sheets  122 , such as, for example, during a manufacturing of reusable notebook  120 . In embodiments, a user of writing system  100  may print the segment code on one or more sheets  122  via a personal-home printer, thereby forming sheets  122  according to the aspects disclosed herein. Combinations thereof may also be foreseen, i.e. that a user may print additional segment codes on a sheet having already preprinted segment codes. 
     It should be understood that a size, shape, and/or quantity of cells  128  shown and described herein is merely an illustrative example such that working surface  126  may include various other sizes, shapes, configurations, quantities, and/or positions of cells  128  on sheet  122 . It should be further understood that the plurality of cells  128  is depicted for illustrative and/or reference purposes only such that cells  128  may not be visible along sheet  122  to a user of writing system  100 . In embodiments, the segment code printed in a cell  128  may be in the form of reading dot codes that correspond to coded data. The reading dot codes printed in a cell  128  may be detected by the imaging device  117  and analyzed to determine a location of writing instrument  110  relative to the reusable notebook, particularly to the working surface  126 , upon decoding the positional information from the reading dot codes. In embodiments, the segment code printed in a cell  128  may include various other suitable forms than the reading dot codes shown and described herein. 
     As described in further detail below, the writing instrument  110  may be configured to detect the segment code positioned within a field of view  10  of the imaging device  117  as the distal end  116  of the writing instrument  110  is positioned over the working surface  126  of the notebook  120 . It should be understood that the segment code printed in the cell  128  may not be visible along the sheet  122  to a user of writing system  100 . In examples, the segment code may be printed with invisible ink e.g., infrared, near-infrared, etc. such that the coded data on the working surface  126  is invisible to the human-eye of a user of writing system  100 . In examples, the printed segment code may be disposed beneath an outer protective layer of a coating disposed over the working surface  126 . 
       FIG.  4    shows additional illustrative hardware components of the computing device  130 , such as, for example, at least one processor  136 , at least one memory  138 , and/or at least one communications module  144 . In examples, the computing device  130  may include a server, a computer, a mobile user device, a tablet, smartwatch, a cloud storage, and/or the like. Although computing device  130  is shown and described herein as a separate device from the writing instrument  110  and/or the reusable notebook  120 , it should be understood that, in embodiments, some or all aspects of the computing device  130  may be integrated within the writing instrument  110  and/or the reusable notebook  120 . Stated differently, the illustrative hardware components of computing device  130  shown and described herein may be integral with one or more of writing instrument  110  and/or reusable notebook  120 . 
     Processor  136  may include any computing device capable of executing machine-readable instructions, which may be stored on a non-transitory computer-readable medium, such as, for example, memory  138 . In examples, processor  136  may include a controller, an integrated circuit, a microchip, a computer, and/or any other computer processing unit operable to perform calculations and logic operations required to execute a program. As described in detail herein, processor  136  is configured to perform one or more operations in accordance with the instructions stored on memory  138 , such as, for example, conversion logic  140 . 
     Still referring to  FIG.  4   , memory  138  may include a non-transitory computer readable medium that stores machine-readable instructions thereon, such as, for example, conversion logic  140 . In examples, conversion logic  140  may include executable instructions that allow the writing system  100  to convert raw image data  142  received from writing instrument  110  e.g., via communications module  144  into converted written data  144  having one or more informational formats. In examples, converted written data  144  may include a handwritten graphical format, a digitized character format, and more. As described in greater detail herein, conversion logic  140  may further facilitate storing converted written data  144  for review by a user of writing system  100  via display  132 . 
     It should be understood that various programming algorithms and data that support an operation of writing system  100  may reside in whole or in part in memory  138 . Memory  138  may include any type of computer readable medium suitable for storing data and algorithms, such as, for example, random access memory (RAM), read only memory (ROM), a flash memory, a hard drive, and/or any device capable of storing machine-readable instructions. Memory  138  may include one or more data sets, including, but not limited to, raw image data  142  captured from imaging device  117 , converted written data  144  generated by processor  136 , and the like. 
     Referring now to  FIG.  5   , an example method  200  of using writing system  100  to record handwritten material e.g., text, drawings, etc. on reusable notebook  120  with writing instrument  110  and converting the handwritten material to one or more electronic formats with computing device  130  is depicted. It should be understood that the steps shown and described herein, and the sequence in which they are presented, are merely illustrative such that additional and/or fewer steps may be included without departing from a scope of this disclosure. 
     At step  202 , imaging device  117  may be initiated via actuator  119 . In this instance, imaging device  117  may capture one or more images during use of writing instrument  110  with reusable notebook  120 . With distal end  116  positioned adjacent to sheet  122 , the field of view  10  of imaging device  117  may project toward working surface  126  and may include one or more cells  128 . The sheet includes a porous surface and a material of the writing instrument, e.g. ink, comprises solid particles having a particle size greater than a porosity of the porous surface. Imaging device  117  may capture images of the coded data printed within those cells  128  that the field of view  10  may be aligned with as writing instrument  110  is moved relative to working surface  126 . 
     Additionally, with tip  118  at least partially disposed within the field of view  10  of imaging device  117 , imaging device  117  may be further operable to capture images of a material e.g., ink, dispensed from tip  118  and onto working surface  126 . It should be appreciated that imaging device  117  may continuously capture images of working surface  126  during use of writing instrument  110  with reusable notebook  120  until deactivating imaging device  117  via actuator  119  and/or until writing system  100  receives an input from a user. 
     For example, referring back to  FIG.  1   , a user of writing system  100  may actuate operative control  129  to initiate transmission of the image data recorded by writing instrument  110  to computing device  130 . In one example, in response to actuating operative control  129 , reusable notebook  120  may transmit a wireless signal via the communications module of reusable notebook  120  to a corresponding communications module of writing instrument  110 . The wireless signal may include one or more instructional commands directing writing instrument  110  to deliver the image data to computing device  130  for processing. 
     Depending on a configuration of operative control  129 , the wireless signal transmitted from reusable notebook  120  to writing instrument  110  may vary with respect to the instructions on which portion of the image data to transmit to computing device  130 . For example, in embodiments where each sheet  122  includes one operative control  129 , reusable notebook  120  may be configured to transmit instructions for delivering all the image data corresponding to a particular sheet  122  upon actuation of operative control  129 . In embodiments where each sheet  122  includes one operative control  129  for each line on sheet  122 , reusable notebook  120  may be configured to transmit instructions for delivering only the image data corresponding to a portion of sheet  122  along the particular line. In embodiments, reusable notebook  120  may include a single operative control  129  for the plurality of sheets  122  such that actuation of operative control  129  may initiate delivery of all the image data for the plurality of sheets  122 . 
     In examples, reusable notebook  120  may be configured such that actuation of operative control  129  initiates a live stream recording by imaging device  117  such that the written markings  121  produced by writing instrument  110  onto sheet  122  are automatically transmitted to computing device  130  as image data. In this instance, operative control  129  is actuated prior to producing written content on reusable notebook  120  such that computing device  130  receives the image data in real-time as writing instrument  110  produces the written markings  121  on sheets  122 . The live communication feed between writing instrument  110  and computing device  130  may be terminated upon subsequent actuation of operative control  129 . It is contemplated that aspects of the present disclosure may be used in an education setting, where, e.g., an instructor, may readily display (e.g., via display  132 ) to students the markings made on sheets  122  in real time. 
     At step  204 , the signal indicative of the transmission command may be received at a communications module of writing instrument  110 . In embodiments, writing instrument  110  may be configured to cease operation of imaging device  117  in response to receiving the transmission command from reusable notebook  120 . In embodiments, imaging device  117  may continue to capture images of reusable notebook  120  as writing instrument  110  processes the signal and delivers the image data to computing device  130 . In this instance, the computing device  130  may receive and store raw image data  142  captured by imaging device  117  onto memory  138 . 
     At step  206 , processor  136  may execute conversion logic  140  to convert the segment code stored in raw image data  142  or printed code or coded data to the corresponding positional information printed in each cell  128 . Further, at step  208 , processor  136  may be configured to associate a relative position of the markings written on working surface  126  by writing instrument  110  with a location of the particular cell  128  that the marking was written adjacent to and/or on. Processor  136  may generate converted written data  144  from the positional information and markings derived from raw image data  142 . Converted written data  144  may be stored in memory  138  and include a plurality of written markings defined by a spatial relationship relative to one another. 
     At step  210 , processor  136  of the computing device  130  may be configured to generate one or more digitized representations of converted written data  144 . For example, processor  136  may produce a graphical representation of converted written data  144  such that the plurality of written markings are superimposed on a backdrop corresponding to sheet  122 . This means that the graphical representation may simulate the markings produced by writing instrument  110  on the reusable notebook  120  in accordance with a movement of tip  118  on sheet  122 . 
     In embodiments, processor  136  may produce a textual representation of converted written data  144  such that the plurality of written markings are analyzed and converted into a character format. In this instance, the textual representation may transform the markings produced by writing instrument  110  on reusable notebook  120  to printed text that may be text-searchable. It should be appreciated that converted written data  144  may be digitized by computing device  130  into various other suitable format representations than those shown and described herein without departing from a scope of this disclosure. 
     Computing device  130  may display the representations of converted written data  144  onto display  132  and allow a user of the writing system  100  to edit the representations via user interface  134 . Computing device  130  may further be operable to transmit the representations to one or more other devices e.g., a computer, a printer, a mobile device, etc., allow for user modification of converted written data  144 , and the like. In embodiments, processor  136  may be configured to conduct one or more analysis of converted written data  144 , such as, for example, an orthography review. It should be appreciated that computing device  130  may be operable to perform the one or more analysis with converted written data  144  formatted in either the graphical or textual representation. Additionally, memory  138  may be operable to store a plurality of representations for each of the plurality of sheets  122  in one or both of the digitized representation formats described herein. 
     In embodiments, computing device  130  may further be configured to generate an audio representation of the written markings in the form of an audio file. In this instance, the converted written data  144  may include an audible transcription of the content written on reusable notebook  120  by writing instrument  110 . Computing device  130  may be operable to play the audio file and/or transmit the audible representation to one or more other devices e.g., a mobile phone, a portable media player, a portable flash drive, a computer, etc.. Additionally and/or alternatively, writing instrument  110  may include a microphone on body  112  such that audible recordings captured by the microphone may be transmitted to computing device  130  e.g., in conjunction with and/or in lieu of raw image data  142  upon actuation of operative control  129 . 
     At step  212 , the written markings on working surface  126  may be removed by a user of writing system  100 . In examples, the material e.g., ink forming the written markings may be removed by applying heat to sheet  122 . In this instance, the material dispensed from working instrument  110  may be configured to dissipate in response to an exposure of a predetermined temperature. In embodiments, the material may be removed by engaging an ancillary device against sheet  122 . In this instance, the material dispensed from the writing instrument  110  may be configured to dissolve, dissipate, and be otherwise removed in response to the ancillary device. In examples, the material may include a thermochromic ink and the ancillary device may include a dry and/or wet apparatus e.g., a fabric, a textile, a cloth, a polymer, etc. for wiping the ink off of working surface  126 . 
     It should be appreciated that thermochromic ink may be erasable in response to encountering heat and/or a wet apparatus. In embodiments, the heat may be applied by placing sheets  122  and/or reusable notebook  120  into a microwave. In embodiments, the wet apparatus may include a cloth or paper having water and/or an alcohol-based substance absorbed therein. In some cases, the water or paper of wet eraser apparatus may be coated with any suitable coating, e.g., Calcium carbonate. In examples of materials suitable for making markings on reusable notebook  120  may include, but is not limited to, non-permanent dry erase ink e.g., silicone polymer, ink comprising solid particles e.g., particles having a size greater than a porosity of sheets  122 , dye-based inks, and more. More specifically materials suitable for making markings on reusable notebook  120  may include non-permanent dry erase ink e.g., silicone polymer, ink comprising solid particles e.g., particles having a size greater than a porosity of sheets  122 . In examples where writing instrument  110  includes a dye-based ink, it should be appreciated that the written markings produced on sheets  122  by writing instrument  110  may be removed with isopropanol and/or other chemical compounds. 
     Accordingly, sheet  122  may be reutilized by a user of writing system  100  for producing further written materials on working surface  126  without generating waste from a disposal of sheet  122 . Further, the written material removed from reusable notebook  120  is stored and accessible to a user of writing system  100  via computing device  130  despite an erasure of the written markings from sheet  122 .
