## Title
Method on a writing instrument having wireless communication capability

## Abstract

A writing instrument (e.g., a pen or stylus) is able to wirelessly receive a message, receive a responsive input from a user (either spoken or written using the writing instrument), convert the user input into text, and transmit the text in a first mode (if the responsive input is spoken) or in a second mode (if the responsive input is written). The first mode and the second modes may correspond, for example, to different recipient groups.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims priority to U.S. Provisional Patent Application No. 61/968,118, filed Mar. 20, 2014, the contents of which are incorporated herein by reference.


TECHNICAL FIELD
The present disclosure is related generally to wireless communication and, more particularly, to writing instruments having wireless communication capability.
BACKGROUND
With profit margins on traditional consumer electronic devices becoming slimmer due to increased competition, wireless device manufacturers are looking for alternative platforms on which to employ their technology. This, along with the increasing availability of WiFi networks and the decreasing cost of WiFi chips, has led to a proliferation of so-called smart devices—e.g., smartphones, smart watches, smart glasses, and smart appliances—which are able to engage in wireless communication with computers or other devices.
Many smart devices have voice recognition capability, allowing them to respond to voice commands. Many of these devices also have speech-to-text capability, allowing users to compose messages (e.g., text messages and emails) by voice and transmit the messages through traditional wireless communication media using such devices. However, because smart devices are often small and may lack a traditional keyboard or keypad input, a user may not be able to set traditional messaging options, such as being able to specify whether to compose a simple “reply” or a “reply to all” response to an incoming message.

DESCRIPTION
According to an embodiment of the disclosure, a writing instrument (e.g., a pen or stylus) is able to wirelessly receive a message, receive a responsive input from a user (either spoken or written using the writing instrument), convert the user input into text, and transmit the text in a first mode (if the responsive input is spoken) or in a second mode (if the responsive input is written). The first mode and the second modes may correspond, for example, to different recipient groups.
In another embodiment, the writing instrument has multiple color sources (e.g., colored ink cartridges, colored pencil tips, electronic ink) from which a user can select. The user writes the message in the selected color. The writing instrument transmits the message in a mode that corresponds to the selected ink color. Each color can, for example, correspond to a different recipient or group of recipients, including different publishing media.
Referring to FIG. 1A, an embodiment of a writing instrument 100 includes a processor 102 and a memory 104. The processor 102 executes instructions and uses data stored in the memory 104 in order to carry out the methods described herein. The writing instrument 100 further includes a directional microphone 106 and an audio codec 108. The microphone 106 detects sound, converts the sound into electrical signals, and transmits those electrical signals to the audio codec 108. The audio codec 108 (which may be a microchip) decodes the electrical signals, converts them into digital signals that the processor 102 is able to interpret, and provides the digital signals to the processor 102. The processor 102 executes a speech-to-text engine 105 to convert the digital signals into text (i.e., a digital representation of the text). The writing instrument 100 further includes a motion sensor 112 (e.g., an accelerometer), which senses the motion of the writing instrument 100, generates electrical signals representing the motion, and provides those signals to the processor 102. The processor 102 executes a motion-to-text engine 107 to convert the signals from the motion sensor 112 into text (digital text).
The elements of FIG. 1A are communicatively linked to one another via one or more data pathways 170. Possible implementations of the data pathways 170 include wires and conductive pathways on a microchip. Possible implementations of the processor 102 include a microprocessor and a controller. In some embodiments, the communication module 110 is a wireless chip or chipset, such as Bluetooth® chip (including Low Energy Bluetooth®), WiFi chip, or a cellular baseband chipset. Possible implementations of the writing instrument 100 include a pen (as shown in FIG. 1A) and a stylus (which is shown in FIG. 1B).
Continuing with FIG. 1A, the writing instrument 100 further includes a color source 114. Possible implementations of the color source 114 include physical colors sources, such as an ink cartridge and a colored pencil lead. In some embodiments, the color source 114 is one of multiple color sources of the writing instrument 100. Each of the color sources has a different color. In the drawing of FIG. 1A, the first color source 114 has material (ink or pencil lead) that is of a first color, the second color source 116 has ink that is of second color, while the third color source 118 has ink that is of a third color. A user may select a color source by pressing down on button 120. When the button 120 is pressed, a mechanical arrangement in the writing instrument 100 extends the correct color source through a lower opening 122 of the writing instrument 100. Through the use of sensors or other feedback mechanisms, the processor 102 is informed of which color the user has selected and can transmit a response to a received wireless message in a mode that is based on which color the user selects.
In some embodiments, the writing instrument 100 has multiple tips (selectable using the button), each of which is of a different size or shape, though not necessarily of a different color.
In an alternative embodiment, shown in FIG. 1B, the writing instrument 100 is a stylus. In this embodiment, the “color source” is not a physical source, but a virtual one. In other words the writing instrument transmits, along with text, signals indicating the color in which the text is to be rendered (e.g., on a display screen of a nearby computing device). Except for the absence of a physical color source, however, the writing instrument embodiment of FIG. 1B has all of the same components and functionality as the writing instrument embodiment of FIG. 1A.
In an embodiment, the writing instrument 100 sends and receives messages to and from one or more publishing media. As used herein “publishing media” refers to an entity that is capable of publishing (e.g., to other users of a medium) text messages. Examples of publishing media include a website, email, and social media such as Facebook®, Twitter®, LinkedIn®, and Tumbler®. In some embodiments, the writing instrument 100 sends and receives messages directly to or from a public network (e.g., the Internet). In other embodiments, the writing instrument 100 operates in conjunction with a computing device, such as the computing device 200 depicted in FIG. 2.
Turning to FIG. 2, a computing device 200 according to an embodiment includes a processor 210, a memory 220 (which can be implemented as volatile memory or non-volatile memory), a network communication module 240 (e.g., WiFI chip or a baseband chipset), a short range wireless controller 242 (e.g., a Bluetooth® controller, such as a BLE controller, an NFC controller, or a wireless infrared controller), a display 260, a speaker 212, and a user interface 250. Each of these elements is communicatively linked to one another via one or more data pathways 270. Possible implementations of the data pathways 270 include wires and conductive pathways on a microchip. Possible implementations of the processor 210 include a microprocessor and a controller. Possible implementations of the computing device 200 include a smartphone and a tablet computer.
The processor 210 retrieves instructions and data from the memory 220 and, using the instructions and data, provides outgoing data to, or receives incoming data from the network communication module 240 and the short-range wireless controller 242.
According to an embodiment, when the writing instrument 100 transmits a message in response to a message previously received (directly from a public network or via the computing device 200, which is connected to the public network) it does so in a mode that is based on how the response message was input into the writing instrument 100. For example, if a user speaks the response into the writing instrument 100 (via the microphone 106), the writing instrument 100 may transmit the text response in a first mode—e.g., transmitting as a “reply all,” transmitting to a first publishing medium (such as Facebook®), and transmitting to a first group of recipients (such as “work colleagues”). If the user writes the response with the writing instrument, the writing instrument may transmit the text response in a second mode—e.g., transmitting the reply only to the sender, transmitting to a second publishing medium (such as Twitter®), and transmitting to a different, second group of recipients (such as “family”). Naturally, the examples given above may be reversed in some embodiments, so that the first mode responses are performed with a speech input and the second mode responses are performed with a written input.
A method that may be carried out in an embodiment will now be described with reference to the flowchart of FIG. 3. At block 302, the writing instrument 100 wirelessly receives a message, either directly from a public network, via WiFi from a local network, or via short-range communication from the computing device 200. At block 304, the writing instrument 100 receives an input of a response to the message. If, at block 306, the response is a speech input (via the microphone 106 and the audio codec 108), the processor 102 executes the speech-to-text engine 105 to convert the speech to text at block 308. The processor 102 then wirelessly transmits the text in a first mode at block 310. Possible implementation of wirelessly transmitting text in the first mode include: transmitting the text to a predetermined group of recipients, transmitting the text as a “reply all,” and transmitting the text to a first publishing medium.
In an alternative embodiment, the processor 102 transmits the text of the response to the computing device 200 via short-range wireless communication (via the communication module 110) indicating to the computing device 200 the nature of the first mode, and the computing device 200 transmits the text of the response in the first mode.
If, at block 306, the response is a written character input (using the color source 114 and detected by the motion sensor 112), the processor 102 executes the motion-to-text engine 107 to convert the motion to text at block 312. The processor 102 then wirelessly transmits the text in a second mode at block 314. Possible implementation of wirelessly transmitting text in the second mode include: transmitting the text to a group of recipients that is different from the predetermined group of the first mode, transmitting the text solely to the sender, and transmitting the text to a second publishing medium.
FIG. 4 shows an example scenario for the procedure carried out according to FIG. 3. In this example, the user, Mary, receives a message from Jane via a social media outlet 402, a public network 404, and the computing device 200. The message may show up on the computing device 200, or may be evident on the writing instrument 100 (e.g., a synthetic voice speaking the message out of a speaker of the writing instrument 100 or on a small display on the writing instrument 100). The message is from Jane, and says “Wanna go out tonite?” Mary gives a voice response of “Sure! What time?” The processor 102 of the writing instrument 100 executes the speech-to-text engine 105 and converts Mary's speech into the digital text “Sure! What time?” Because the response is given in spoken form, the processor 102 sends the message as a “reply all.”
FIG. 5 shows another example scenario for the procedure carried out according to FIG. 3. In this example, Mary does not speak the response, but writes it: “Only if Abbey doesn't come.” The processor 102 of the writing instrument 100 detects motion signals from the motion sensor 112 and executes the motion-to-text engine 107 to convert the written characters into text. Because the response is given in the form of written characters, the processor 102 sends the message only to Jane.
A method that may be carried out in an embodiment will now be described with reference to the flowchart of FIG. 6. At block 602, the processor 102 detects a user selection of an ink color (e.g., the first color of color source 114, the second color of color source 116, or the third color of color source 118). At block 604, the processor 102 of the writing instrument 100 detects, via the motion sensor 112, one or more characters being written by the writing instrument 100 in the selected color. At block 606, the processor 102 executes the motion-to-text engine 107 to convert the written characters into text. At block 608, the writing instrument 100 wirelessly transmits the text in a mode corresponding to the selected color. For example, if red has been selected, and red corresponds to Twitter®, then the writing instrument 100 transmits the text to Twitter®. If black has been selected, and black corresponds to Facebook®, then the writing instrument 100 transmits the text to Facebook®.
As previously mentioned, the writing instrument 100 may have multiple tips, each with its own size or shape, but not necessarily with its own color. In such case, each size or shape could be associated with a different text mode in the manner described in conjunction with FIG. 6.
It should be understood that the exemplary embodiments described herein should be considered in a descriptive sense only and not for purposes of limitation. Descriptions of features or aspects within each embodiment should typically be considered as available for other similar features or aspects in other embodiments.
