## Title
Utilizing mood sensors in an electronic messaging environment

## Abstract

A method, system and computer-usable medium are disclosed for determining the behavioral mood of an electronic messaging system user. User input is provided through one or more input receptors of an electronic device. The user input is collected by the mood identification system. The collected input is processed to generate behavioral biometrics, which are in turn correlated to predetermined behavioral moods, each of which has a corresponding behavioral mood indicator. The behavioral mood of the recipient user is indicated by applying text attributes to the user's identifier (ID) or by displaying an icon proximate to the user's ID.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
Embodiments of the disclosure relate in general to the field of computers and similar technologies, and in particular to software utilized in this field. Still more particularly, it relates to determining the behavioral mood of an electronic messaging system user.
2. Description of the Related Art
An instant messaging system (IMS) provides a simple way to exchange real-time, text-based messages between users who are connected to on-line or electronic networking environments such as the Internet, intranets, and extranets. These systems, which have gained popularity due to their simplicity and ease of use, require both sender and recipient to be simultaneously logged-on to exchange messages. To send an IMS message, a user generally logs on with an IMS client, selects one or more recipients from an address book of other IMS users that are indicated to be on-line, and then composes and sends their message.
One issue with IMS systems is the inability to determine a user's mood. Current approaches to this issue include the user applying emoticons or icons within the text of the message to indicate their mood or disposition. However, this can be problematic, as the emoticon or icon may not accurately portray the user's actual mood. This misdirection may be intentional or unintentional. Regardless, the indication of the user's actual mood is inaccurate which can lead to misunderstandings and other communication issues between messaging system users. In addition, it is generally not possible to determine the mood of a user prior to establishing a message session. For example, if it were possible to indicate that the intended recipient of a message is currently angry or in a bad mood, the message originator could decide to postpone the messaging session. Currently, this is not possible.
Various approaches exist for the autodetermination of a user's changing mood through the collection, analysis and correlation of behavioral biometrics. As an example, a user's mood can be ascertained by analyzing the pressure applied to the keys of a touch-sensitive keyboard, their typing speed and patterns, and the pauses between words. These behavioral biometrics can also be combined with other biometrics, such as skin temperature, heart rate, and other biophysical factors, thus deriving their mood. In view of the foregoing, it would be advantageous if these approaches to mood determination could be used by messaging clients to improve the interaction between messaging system users.
BRIEF SUMMARY OF THE INVENTION
The present invention includes, but is not limited to, a method, system and computer-usable medium for determining the behavioral mood of an electronic messaging system user. In various embodiments of the invention, instant messaging system (IMS) operations are initiated with the selection of an IMS message recipient within the user interface (UI) of an IMS client. The behavioral mood of the recipient user is indicated by the application of visual attributes, such as bolding or coloring the text of the user's identifier (ID) or by displaying an icon proximate to the user's ID. As an example, a smiling face icon may indicate that the IMS user is in a good mood, while a frowning face icon might indicate that the IMS user is in a bad mood.
In different embodiments, the IMS user provides user input to an electronic device through one or more input receptors. As the user input is provided to the various input receptors, it is collected by the mood identification system. The collected input is then processed to generate behavioral biometrics, which are in turn correlated to predetermined behavioral moods. Each of these predetermined behavioral moods has a corresponding behavioral mood indicator which is applied to the user ID during the course of the IMS message session. In one embodiment, the behavioral mood indicator changes as the behavioral mood of the user changes, and is indicated through the application of visual attributes, such as changes in the color of the user's text ID, or by displaying different icons. For example, smiling, neutral, stern, or sad face icons are displayed to indicate the user's behavioral mood has changed respectively from happy, to receptive, to concerned, to angry.
In another embodiment, behavioral biometrics are collected during the generation of the IMS message and are then processed to generate a set of generalized behavioral biometrics. The set of generalized behavioral biometrics is then correlated to predetermined behavioral moods to indicate the user's generalized behavioral mood when the IMS message was generated. The visual attribute or icon associated with the generalized behavioral mood is then applied to the IMS message. In one embodiment, IMS messages can be sorted by their respective behavioral moods, much like a list can be sorted in ascending or descending alphabetical order. The above, as well as additional purposes, features, and advantages of the present invention will become apparent in the following detailed written description.

FIG. 1 is a block diagram of an exemplary client computer 102 in which the present invention may be utilized. Client computer 102 includes a processor unit 104 that is coupled to a system bus 106. A video adapter 108, which controls a display 110, is also coupled to system bus 106. System bus 106 is coupled via a bus bridge 112 to an Input/Output (I/O) bus 114. An I/O interface 116 is coupled to I/O bus 114. The I/O interface 116 affords communication with various I/O devices, including a keyboard 118, a mouse 120, a Compact Disk-Read Only Memory (CD-ROM) drive 122, a floppy disk drive 124, and a flash drive memory 126. The format of the ports connected to I/O interface 116 may be any known to those skilled in the art of computer architecture, including but not limited to Universal Serial Bus (USB) ports.
Client computer 102 is able to communicate with a service provider server 152 via a network 128 using a network interface 130, which is coupled to system bus 106. Network 128 may be an external network such as the Internet, or an internal network such as an Ethernet Network or a Virtual Private Network (VPN). Using network 128, client computer 102 is able to use the present invention to access service provider server 152.
A hard drive interface 132 is also coupled to system bus 106. Hard drive interface 132 interfaces with a hard drive 134. In a preferred embodiment, hard drive 134 populates a system memory 136, which is also coupled to system bus 106. Data that populates system memory 136 includes the client computer's 102 operating system (OS) 138 and software programs 144.
OS 138 includes a shell 140 for providing transparent user access to resources such as software programs 144. Generally, shell 140 is a program that provides an interpreter and an interface between the user and the operating system. More specifically, shell 140 executes commands that are entered into a command line user interface or from a file. Thus, shell 140 (as it is called in UNIX®), also called a command processor in Windows®, is generally the highest level of the operating system software hierarchy and serves as a command interpreter. The shell provides a system prompt, interprets commands entered by keyboard, mouse, or other user input media, and sends the interpreted command(s) to the appropriate lower levels of the operating system (e.g., a kernel 142) for processing. While shell 140 generally is a text-based, line-oriented user interface, the present invention can also support other user interface modes, such as graphical, voice, gestural, etc.
As depicted, OS 138 also includes kernel 142, which includes lower levels of functionality for OS 138, including essential services required by other parts of OS 138 and software programs 144, including memory management, process and task management, disk management, and mouse and keyboard management.
Software programs 144 may include a browser 146, email client 148, and instant messaging system (IMS) client 154. Browser 146 includes program modules and instructions enabling a World Wide Web (WWW) client (i.e., client computer 102) to send and receive network messages to the Internet using HyperText Transfer Protocol (HTTP) messaging, thus enabling communication with service provider server 152. The IMS client 154 further comprises a mood indication system 150. The mood indication system 150 includes code for implementing the processes described in FIGS. 2 through 5 described hereinbelow. In one embodiment, client computer 102 is able to download the mood indication system 150 from a service provider server 152.
The hardware elements depicted in client computer 102 are not intended to be exhaustive, but rather are representative to highlight components used by the present invention. For instance, client computer 102 may include alternate memory storage devices such as magnetic cassettes, Digital Versatile Disks (DVDs), Bernoulli cartridges, and the like. These and other variations are intended to be within the spirit and scope of the present invention.
FIG. 2 shows a mood indication system as implemented in an embodiment of the invention to determine the behavioral mood of an instant messaging system (IMS) user. In various embodiments, instant messaging system (IMS) operations are begun with IMS message user ‘A’ 202 accessing IMS system 210 through network 208 to initiate an IMS session with IMS message user ‘B’ 202. Once the IMS session is initiated, then the collection of behavioral biometrics and their correlation to corresponding behavioral moods is activated by the IMS mood indication system 206, 216 implemented on the respective computer systems 204, 214 of IMS users ‘A’ 202 and ‘B’ 212.
Skilled practitioners of the art will be aware that a variety of approaches exist for determining the behavioral mood of a user through the collection, analysis and correlation of behavioral biometrics. In various embodiments, IMS users ‘A’ 202 and ‘B’ 212 provide user input to their respective computer systems 204, 214 through one or more input receptors. The input receptor may be keyboard comprising either electro-mechanical or touch-sensor keys, a touch-sensitive screen, a touchpad, a pointing device such as a mouse or graphics pad, a biometric sensor, or any combination of these.
As the user input is provided to the various input receptors, it is collected by the mood identification system 206, 216 respectively implemented on their computer systems 204, 214. The collected input is then processed to generate behavioral biometrics, which are in turn correlated to predetermined behavioral moods. For example, each user has a distinct keystroke pattern when using a keyboard. This pattern changes with the behavioral mood of the user. Keystroke latencies and durations can be captured from a keyboard comprising electro-mechanical keys. Similarly, different pressures exerted on individual keys can be captured from a keyboard comprising touch-sensor or pressure sensitive keys. As described in greater detail herein, these patterns, latencies, durations and pressures, when analyzed and correlated, can be indicators of the behavioral mood of the user.
As behavioral biometrics are collected and correlated to corresponding behavioral moods, the behavioral mood of IMS user ‘A’ 202 and IMS user ‘B’ 212 is indicated by the application of an icon 220 proximate to the user's ID 222 within the IMS message 218. As an example, a smiling face icon may indicate that the IMS ‘A’ 202 user is in a good mood, while a frowning face icon might indicate that the IMS user ‘B’ 212 is either upset or in a bad mood. In one embodiment, the behavioral mood indicators change as the behavioral mood of the user changes. In this embodiment, different icons are displayed, such as smiling, neutral, stern, or sad face icons to indicate the user's behavioral mood has changed respectively from happy, to receptive, to concerned, to angry.
FIG. 3 shows a flowchart of a mood indication system as implemented in an embodiment of the invention to indicate the behavioral mood of a user when performing instant messaging system (IMS) operations. In this embodiment, IMS operations are begun in step 302, followed by the selection of an IMS message recipient within the user interface (UI) of an IMS client in step 304. Once the recipient is selected, a determination is made in step 306 whether the selected recipient's behavioral mood is indicated. In one embodiment, the behavioral mood of an IMS user is indicated by the application of visual attributes, such as bolding or coloring the text of the user's IMS identifier (ID). For example, the application of bolding and the color red to the IMS user's ID may indicate that the IMS user is in a bad mood or upset. In another embodiment, the IMS user's behavioral mood is indicated by the application of an icon proximate to the user's ID. As an example, a smiling face icon may indicate that the IMS user is in a good mood, while a frowning face icon might indicate that the IMS user is either upset or in a bad mood. Similarly, a stern face icon might indicate the IMS user is in a hurry or is concentrating, while a surprised face icon might indicate that the IMS user has been interrupted.
If it is determined in step 306 that the IMS recipient's mood is not indicated, then a determination is made in step 308 whether to proceed with initiating an IMS session with the selected recipient. If it is determined in step 308 to not proceed with initiating an IMS session with the recipient, then a determination is made in step 332 whether another IMS recipient is to be selected. If it is decided in step 332 to select another IMS recipient, then the process is repeated, beginning with the selection of an IMS recipient in step 304. Otherwise, IMS operations are ended in step 334.
However, if it is determined in step 308 to proceed with initiating an IMS session with the selected recipient, then contact is initiated in step 310. Upon contact, the recipient's last-known behavioral mood is determined and displayed in step 312. As an example, the selected IMS recipient may be indicated to be currently on-line, but their behavioral mood is not displayed because the amount of elapsed time since the recipient's last IMS activity has exceeded the mood indication system's time-out parameters. As a result, the recipient's last known behavioral mood, along with the elapsed time since it was last updated, will be displayed when the recipient responds to the initiated contact.
Once the recipient's last-known behavioral mood is displayed in step 312, or if it is determined in step 306 that the recipient's current behavioral mood is displayed, then a determination is made in 314 whether the recipient's behavioral mood is suitable to initiate an IMS session. If it is determined in step 314 that the recipient's behavioral mood is not suitable to initiate an IMS session, then the process is repeated, beginning with step 332, where a determination is made whether to select another IMS recipient.
However, if it is determined in step 314 that the recipient's behavioral mood is suitable to initiate an IMS session, then the collection of behavioral biometrics and their correlation to corresponding behavioral moods is activated in step 316. Those of skill in the art will be knowledgeable of a variety of approaches for determining the behavioral mood of a user through the collection, analysis and correlation of behavioral biometrics. In various embodiments, the IMS user provides user input to an electronic device through one or more input receptors. The electronic device may be a personal computer (PC), a laptop or tablet PC, a personal digital assistant (PDA), a wireless device such as a cell phone, or any device capable of receiving input and communicating with other electronic devices. The input receptor may be keyboard comprising either electro-mechanical or touch-sensor keys, a touch-sensitive screen, a touchpad, a pointing device such as a mouse or graphics pad, a biometric sensor, or any combination of these.
As the user input is provided to the various input receptors, it is collected by the mood identification system. The collected input is then processed to generate behavioral biometrics, which are in turn correlated to predetermined behavioral moods. For example, each user has a distinct keystroke pattern when using a keyboard. This pattern changes with the behavioral mood of the user. Keystroke latencies and durations can be captured from a keyboard comprising electro-mechanical keys. Similarly, different pressures exerted on individual keys can be captured from a keyboard comprising touch-sensor or pressure sensitive keys. These patterns, latencies, durations and pressures, when analyzed and correlated, can be indicators of the behavioral mood of the user. To continue the example, a user who forcibly depresses keys with a deliberate cadence is likely angry or upset. A user who types rapidly may be intensely focused on what they are doing, whereas a series of lackadaisical or relatively slow and soft keystrokes may indicate that the user is calm and relaxed. Similar analysis and correlation can be applied to behavioral biometrics collected from other input receptors. As another example, the velocity, acceleration and deceleration of pointing device can likewise provide indications of the user's behavioral mood, whether it is a mouse, a stylus on a PDA or graphics pad, or a human finger on a touch-pad or touch-sensitive screen.
Once collection of behavioral biometrics and their correlation to corresponding behavioral moods is activated in step 316, a determination is made in step 318 whether to display behavioral mood indicators in real-time. In one embodiment, the behavioral mood indicator changes as the behavioral mood of the user changes, and is indicated through the application of visual attributes, such as changes in the color of the user's text ID. In another embodiment, different icons are displayed, such as smiling, neutral, stern, or sad face icons to indicate the user's behavioral mood has changed respectively from happy, to receptive, to concerned, to angry. If it is determined in step 318 that these visual attributes or icons are to be displayed in real-time, then they are activated for display during the generation of the IMS message in step 320.
Regardless of whether it is decided in step 318 to not display the behavioral mood indicators, the IMS message session is conducted in step 322, with an ongoing determination made in step 324 to continue the IMS session. If it is determined in step 324 to continue the IMS session, then it is continued, beginning with step 322. If it is decided in step 324 to no longer continue the IMS session, then a determination is made in step 326 whether to apply behavioral mood indicators to the IMS message once it is generated. In one embodiment, behavioral biometrics are collected during the generation of the IMS message and are then processed to generate a set of generalized behavioral biometrics. The set of generalized behavioral biometrics is then correlated to predetermined behavioral moods to indicate the user's generalized behavioral mood when the IMS message was generated. The visual attribute or icon associated with the generalized behavioral mood is then applied to the IMS message. In another embodiment, IMS messages can be sorted by their respective behavioral moods, much like a list can be sorted in ascending or descending alphabetical order.
If it is decided in step 326 to apply behavioral mood indicators to the IMS message once it is generated, then they are applied in step 328. If it is decided in step 326 to not apply the behavioral mood indicators once it is generated, or if they are applied in step 328, a determination is made in step 330 whether to continue IMS operations. If it is determined in step 330 to continue IMS operations, then the process is repeated, beginning with the selection of another IMS recipient in step 332. Otherwise, IMS operations are ended in step 334.
FIG. 4 shows a simplified IMS user interface (UI) 402 as implemented with a mood indication system to indicate the behavioral mood of a user during the generation of an IMS message. In this embodiment, the IMS UI 402 is comprised of an IMS message window 404, an IMS user directory window 406, and cursor 416. The IMS directory window 406 is further comprised of a listing of IMS user IDs 408, their current IMS status 410, and an indicator of their current behavioral mood 412. When IMS operations are begun, the IMS message originator (“John”) selects an IMS message recipient (“Bob”) with a user gesture such as a double mouse-click once the cursor 416 is placed over the selected recipient's user ID. As illustrated in FIG. 4, an icon indicating a calm, neutral, or receptive, behavioral mood is displayed for “Bob”. The IMS message session is then begun in IMS message window 404. During the message session, the respective user ID 418 of each user (“John” and “Bob”) is displayed with the user's corresponding message segments 420.
As described in greater detail herein, user input is received by one or more input receptors implemented on each user's computer and is collected by the mood identification system as the IMS message session progresses. The collected user input is then processed to generate behavioral biometrics, which are in turn correlated to predetermined behavioral moods. Each of these predetermined behavioral moods has a corresponding behavioral mood indicator which is applied to the user ID 418 during the course of the IMS message session. In one embodiment, the behavioral mood indicator changes as the behavioral mood of the user changes, and is indicated through the application of visual attributes, such as changes in the color of the user's text ID 418. In another embodiment, different icons 422, 424, 426, 428, such as smiling, neutral, or sad face icons, are displayed proximate to the user ID 418 to indicate the user's behavioral mood has changed respectively from happy, to receptive, to angry.
FIG. 5 shows a simplified IMS user interface (UI) 402 as implemented with a mood indication system to indicate the generalized behavioral mood of a user when an IMS conversation generated. In this embodiment, IMS UI 402 comprises stored IMS conversations (i.e. transcripts) 504, further comprising IMS folders 506 and individual IMS transcripts 508. As described in greater detail herein, user input is received by one or more input receptors implemented on each user's computer and is collected by the mood identification system as the IMS session progresses. The collected user input is then processed to generate a set of generalized behavioral biometrics. The set of generalized behavioral biometrics is then correlated to predetermined behavioral moods to indicate the user's generalized behavioral mood when the IMS transcripts were generated. The visual attribute or icon associated 510 with the generalized behavioral mood is then applied to the IMS transcript 508. In one embodiment, IMS transcript 508 can be sorted by their respective behavioral moods 512, 514, 516, much like a list can be sorted in ascending or descending alphabetical order.
