## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. patent application Ser. No. 15/397,984 filed Jan. 4, 2017, entitled “Calendar Comparison System and Method,” which is related to and claims priority under 35 U.S.C. § 119(e) to U.S. Patent Application No. 62/276,105, filed Jan. 7, 2016, entitled “Calendar Comparison System and Method,” the entire contents of which are incorporated herein by reference.


BACKGROUND
Conventionally, it is quite difficult to schedule an in-person meeting, a telephone call, a video conference, or another type of meeting between at least two people. The degree of difficulty increases substantially when more than two people attempt to schedule the meeting. This difficulty is oftentimes based on the inability to compare a calendar of a first person with a calendar of a second person. In many instances it is very difficult to share availability with others due to company policies or security policies. The first person may not have any information about the calendar of the second person and cannot view information associated with the calendar of the second person. Current calendar comparison techniques often involve manual work and a significant amount of wasted communication. In one example, the first person may send an email to parties to be included in the meeting, suggest potential available times, and receive an email from each of the parties with different times that conflict with one another. The first person then has to suggest different available times and the process starts all over again. Often, the time to set up the meeting may exceed the duration of the actual meeting.
It is with these issues in mind, among others, that various aspects of the disclosure were conceived.
SUMMARY

DETAILED DESCRIPTION
For the purpose of promoting an understanding of the principles of the present disclosure, reference will now be made to the embodiments illustrated in the drawings, and specific language will be used to describe the same. It will, nevertheless, be understood that no limitation of the scope of the disclosure is thereby intended; any alterations and further modifications of the described or illustrated embodiments, and any further applications of the principles of the disclosure as illustrated therein are contemplated as would normally occur to one skilled in the art to which the disclosure relates.
The client computing devices and the server computing device communicate over a communications network using Hypertext Transfer Protocol (HTTP) and/or other communications protocols. HTTP provides a request-response protocol in the client-server computing model. A client application running on the client computing device may be a client and a server application running on the server computing device may be the server, e.g., a web server. The client submits, for example, an HTTP request to the server. The web server of the server computing device provides resources, such as Hypertext Markup Language (HTML) files and/or other content, and performs other functions on behalf of the client, and returns an HTTP response message to the client. Other types of communications using different protocols may be used in other examples.
The one or more computing devices may communicate based on representational state transfer (REST) and/or Simple Object Access Protocol (SOAP). As an example, a first computer (e.g., a client computer) may send a request message that is a REST and/or a SOAP request formatted using Javascript Object Notation (JSON) and/or Extensible Markup Language (XML). In response to the request message, a second computer (e.g., a server computer) may transmit a REST and/or SOAP response formatted using JSON and/or XML.
Aspects of a system and method for calendar comparison provide a trusted third party server system for communicating with a plurality of client computing devices. Each user of each client computing device may agree to use the trusted third party server system. After agreeing to use the trusted third party server system, the user may select at least one other user to share calendar information with and receive calendar invitations from other users, view calendar information from the at least one other user, automatically determine a list of open times for a particular appointment or meeting with the at least one other user, automatically schedule a best time for the particular appointment or meeting for the at least one user, and send meeting confirmations for the best time to the at least one user.
For example, the system and method provide efficient scheduling of appointments and meetings for a plurality of users. Each user may be associated with a different calendaring system and/or organization (e.g., Microsoft Outlook/Exchange associated with a Company A, Google Calendar associated with a personal account, iCal associated with a Company B, and IBM Notes associated with a government account, among others). Conventionally, a first user (in company A) may not be permitted by their organization to share their calendar information with a second user (in company B) because it would require allowing access to corporate network resources to a user outside the company. However, the trusted third party server system allows the first user to share their calendar information with the second user without requiring either company A or company B to provide access to their network resources.
A server may receive a plurality of registration requests from a plurality of user client computing devices. In response to the registration request, the server may send a response comprising a verification message that includes a one-time use uniform resource locator (URL) to the user client computing device. The user of the client computing device may verify the registration request by selecting the URL. Upon verification, the server may store user information for each user in a database such as calendar information.
The server may receive a calendar invitation from a first user that invites a second user to share calendars. The server may send information associated with the calendar invitation to the second user. If the second user approves the calendar invitation, the first user and the second user may share their calendar information and send appointment/meeting requests to one another. In a further embodiment, based on personalized settings, users associated with the first user (e.g., users having a same email domain or users on a white list) may share calendar information and send appointment/meeting requests with the second user and users associated with the second user (e.g., users having a same email domain or users on a white list) may share calendar information and send appointment/meeting requests with the first user.
The server may receive an automated calendar comparison request from the first user that desires to schedule an appointment/meeting/event with the second user. The server may use the user information, determine a list of open times for the appointment, and transmit the list of open times to the client computing device of the first user and/or the client computing device of the second user. In an exemplary embodiment, the server automatically schedules the appointment by selecting a best open time and transmits calendar confirmations to the first user and the second user.
FIG. 1 shows a block diagram of a calendar comparison system 100 according to an example embodiment. The calendar comparison system 100 includes a calendar comparison server 102 and at least two client computing devices 104 and 106 that communicate via a communications network 108. In one embodiment, the client computing device 104 may be associated with a company A and the client computing device 106 may be associated with a company B. The calendar comparison system 100 further includes a calendar comparison database 110.
Although the calendar comparison server 102 is shown as a single server computing device, it is contemplated that the calendar comparison server 102 may include multiple servers, for example, in a cloud computing configuration. It is also contemplated that the client computing device 104 or the client computing device 106 may include multiple computing devices, for example, in a cloud computing configuration.
The communication network 108 can be the Internet, an intranet, or another wired or wireless communication network. For example, the communication network 108 may include a Mobile Communications (GSM) network, a code division multiple access (CDMA) network, 3rd Generation Partnership Project (GPP), an Internet Protocol (IP) network, a wireless application protocol (WAP) network, a WiFi network, or an IEEE 802.11 standards network, as well as various communications thereof. Other conventional and/or later developed wired and wireless networks may also be used.
The calendar comparison database 110 comprises an organized collection of data. The data may include one or more tables comprising user information including contact information, calendar information, permission information, and rule information. In an example, each user of the calendar comparison system 100 may have user information. A user may have contact information such as name information (e.g., first name, last name), address information (e.g., 123 Main Street, Anytown, MO, USA), phone number information (e.g., 555-123-4567), email information (bob@bigcompany.com), username information, password information, and social media information (e.g., @bobbigcompany). The user may have calendar information that provides information regarding dates and days for the user and appointment/meeting information regarding appointments for the user for each of the dates and days. The calendar information is used to indicate whether the user is available/free or not available/busy at a particular time on a particular date. The permission information indicates other associated users for each particular user. As an example, a first user may select to share their calendar and receive appointment requests with a second user but not with a third user, etc. The first user may block the third user. Each user may have rule information that indicates preferences for scheduling with other users, e.g., no meetings on Saturdays, no meetings before 9 a.m., and no meetings from 12 p.m.-1 p.m. each day, among others.
The calendar comparison server 102 includes at least one processor 112 to process data and memory 114 to store data.

FIG. 2 illustrates a block diagram of the calendar comparison server 102 according to an example embodiment. The calendar comparison server 102 includes computer readable media (CRM) 202 in memory on which the calendar comparison application 120 is stored. The computer readable media 202 may include volatile media, nonvolatile media, removable media, non-removable media, and/or another available medium that can be accessed by the processor 112. By way of example and not limitation, the computer readable media 202 comprises computer storage media and communication media. Computer storage media includes non-transitory storage memory, volatile media, nonvolatile media, removable media, and/or non-removable media implemented in a method or technology for storage of information, such as computer/machine-readable/executable instructions, data structures, program modules, or other data. Communication media may embody computer/machine-readable/executable instructions, data structures, program modules, or other data and include an information delivery media or system, both of which are hardware.
The calendar comparison application 120 includes a user account module 204 for receiving, storing, verifying, and resetting information associated with accounts for using the calendar comparison system 100. The information associated with the accounts may include username and password information, contact information including personally identifiable information (PII), and calendar information, among other information. When a user first uses the calendar comparison application 120, the user is asked to create a user account. The user may input a username such as an email address and a password, and transmit this information to the calendar comparison application 120. The user account module 204 stores a representation of this information in the database 110. The user account module 204 may send an email to an email address associated with the user account including a one-time use URL that when selected, verifies the email address for use with the calendar comparison application 120.
After the user account is created, the client computing device 104 or the client computing device 106 may transmit a representation of the username and a representation of the password to the calendar comparison server 102. The calendar comparison server 102 verifies the username and password upon receipt and determines whether the user is an authorized user of the calendar comparison application 120. If the user is not an authorized user, then they may be denied further access to the calendar comparison application 120.
The user may provide the calendar comparison server 102 access to calendar information provided by a third party server. The calendar comparison server 102 may import and store a copy of the calendar information for the user in the database 110. As an example, the user may provide the calendar comparison server 102 with Calendaring Extensions to WebDAV or CalDAV access to the calendar information by providing username information and/or password information. As a result, the calendar comparison server 102 may be granted view, edit, and delete access to the calendar information stored by the third party server. The calendar comparison server 102 may synchronize the calendar information provided by the third party server with the calendar information stored in the database 110 and may push data to the third party server and pull data from the third party server.
As an example, the user may provide the calendar comparison server 102 access to the following third party calendaring systems such as Microsoft Outlook/Exchange, Google Calendar iCal, and IBM Notes, among others.
The user account module 204 may receive and store additional information in the database 110 for each user such as a telephone number, social network information (e.g., a TWITTER handle), video conference call information (e.g., a SKYPETM name), physical address information, fingerprint information, voice recognition information, facial information, other biometric information, and other information that may be used to identify the user.
The user account module 204 may provide an interface for resetting password information associated with a particular user account. If a user is unable to provide a correct password or other authentication information after a particular number of incorrect attempts or the password or other authentication information is unknown, the user account module 204 may transmit a “Forgot Password” user interface. The user may submit a request that the calendar comparison server 102 reset the password associated with the user account and send an email to an email address associated with the user account including a one-time use URL that when selected, displays a web-based user interface allowing the user to reset their password and create a new password for use with the user account. The user account module 204 may also reset the password in other ways.
The calendar comparison application 120 includes a contacts module 206 for creating and associating a list of approved contacts with each user account. Once a user has verified their email address for use with the calendar comparison application 120, the user may send an invitation to another user. A first user may use the client computing device 104 to send an invitation to a second user using the client computing device 106. The second user may accept the invitation. At this point, the first user and the second user are approved contacts and each user may send calendar invitations to one another and view calendar information. The first user may continue to send additional invitations to other users to develop the list of approved contacts. The list of approved contacts may be users having a same email domain or users on a white list. This white list may be associated with the user account. Alternatively, the contacts module 206 may receive a list of contacts imported from the third party server and invitations may be automatically sent to each of the contacts imported from the third party server. The invitation may be sent as an email, a text message, a message in an application, or another format. In addition, each user may create a list of banned contacts. The banned contacts are not allowed to send invitations, view calendar information, and/or send scheduling requests. The contacts module 206 may store this list of banned contacts in addition to the list of approved contacts in the database 110.
The calendar comparison application 120 further includes a scheduling module 208 for receiving a scheduling request from a client computing device such as the client computing device 104 or the client computing device 106. The scheduling request may be received in a variety of different formats and may include PII that may be used to determine a list of contacts for a meeting. The scheduling module 208 may receive an email from an authorized user of the calendar comparison application 120 that includes a list of email addresses, a time period, and a desired timeframe that may be provided in the body of the email and/or the subject of the email. In one example, the email may be sent to a particular email address associated with the calendar comparison application 120 such as scheduleme@approvedcontact.com. The email addresses in the “TO” line, “CC” line, and “BCC” line are determined and the list of contacts are determined based on the email addresses. As an example, the scheduling module 208 may query the database 110 to determine the associated unique identifier for each email address.
Alternatively, the scheduling module 208 may receive a message such as a text message from an authorized user of the calendar comparison application 120 that includes a list of telephone numbers and/or a list of names and/or a list of email addresses, a time period, and a desired timeframe. In one example, the message may be sent to a particular telephone number such as 888-867-8309. The scheduling module 208 may query the database 110 to determine the associated unique identifier for each telephone number.
Alternatively, a user may use a web interface provided by the scheduling module 208 to select one or more contacts for a meeting. The one or more contacts may be based on the list of approved contacts for the user and other available contacts. In addition, the user may select a desired timeframe for the meeting, e.g., the next day, the next week, the next month.
In an additional embodiment, the scheduling module 208 may provide a telephone interface such as an integrated voice response (IVR) system that receives an incoming call from a user and determines the identity of the user based on the incoming call information, e.g., caller ID information and direct inward dialing (DID) information. The caller may select contacts for the meeting using the telephone interface, a time period, and a desired timeframe.
In a further embodiment, the scheduling module 208 may provide a web application programming interface (API) that comprises an interface including one or more uniform resource identifiers (URIs) that receive a request from a client computing device. The request may be formatted in a particular format such as JSON, XML, or another format and may include the PII that may be used to identify the list of contacts, a time period, and a desired timeframe. The request may be received by the web API and may be sent from a number of applications including FACEBOOKTM, LINKEDINTM, TWITTERTM, YAMMERTM, JIVETM, SLACKTM, SNAPCHATTM, HIPCHATTM, INSTAGRAMTM, PINTERESTTM, YOUTUBETM, OPENTABLETM, UBERTM, SKYPETM, NEXVORTEXTM, Voice Over IP telephone/video, WEBEXTM, GOTOMEETINGTM, IMEETTM, and others. As an example, a user having a TWITTER handle @Bob may transmit the following tweet: “Hey @Jim and @Susan, lets have dinner next week #ScheduleMe.” By including the hashtag “#ScheduleMe,” the scheduling module 208 receives a request, forwarded from TWITTER using the web API, determines the list of users based on the included TWITTER handles including Bob, Jim, and Susan, a time period of 6-7 pm based on Jim's personal preference information, and a timeframe of the next week. The scheduling module 208 then determines whether Bob, Jim, and Susan have an open time between 6-7 pm for the next week. As another example, a user, Bob, may send a FACEBOOK message, “Hey Jim and Susan, lets have dinner next week #ScheduleMe.” By including the hashtag “#ScheduleMe,” the scheduling module 208 receives a request, forwarded from FACEBOOK using the web API, determines the list of users based on the included FACEBOOK names including Bob, Jim, and Susan, a time period of 6-7 pm, and a timeframe of the next week. The scheduling module 208 then determines whether Bob, Jim, and Susan have an open time between 6-7 pm for the next week. In another example, a user, Bob, may send a LINKEDIN message, “Hey Jim and Susan, lets have dinner next week #ScheduleMe.” By including the hashtag “#ScheduleMe,” the scheduling module 208 receives a request, forwarded from LINKEDIN using the web API, determines the list of users based on the included LINKEDIN names including Bob, Jim, and Susan, a time period of 6-7 pm, and a timeframe of the next week. The scheduling module 208 then determines whether Bob, Jim, and Susan have an open time between 6-7 pm for the next week.
Each user may set calendar comparison rules that the scheduling module 208 may utilize when receiving a calendar comparison request from a client computing device. As an example, the user may only allow calendar invitations from an approved contact, a user having a similar email address associated with an approved contact, any user having a user account associated with the calendar comparison application 120, or any user including a user not having a user account associated with the calendar comparison application 120. In one example, a user having a similar email address may be a user associated with a same organization or domain. As an example, a@abc.com may be an approved contact of b@abc.com, but not an approved contact of c@abc.com. a@abc.com may allow calendar invitations only from b@abc.com or may also allow calendar invitations from c@abc.com.
The scheduling module 208 may receive a desired timeframe for the meeting such as a next week or a next month. The scheduling module 208 may determine one or more best times for the meeting based on the desired timeframe, the calendar information for each of the list of contacts, and based on user preferences. The scheduling module 208 may query the database to obtain the copy of the calendar information for each of the list of contacts for the meeting to determine possible times and the one or more best times for the meeting. The calendar information may include information regarding whether the user is busy/available for each moment in time for the desired timeframe. The scheduling module 208 may determine the one or more best times based on the times when each of the list of contacts are available for the desired timeframe and based on the user preferences for each of the list of contacts. The user preferences may include specific hours each day that the user may be available for meetings and specific days of the week that the user may be available for meetings.
After the scheduling module 208 determines the one or more best times for the meeting, the scheduling module 208 may automatically schedule the meeting on each of the user's calendars, and transmit a response to the client computing device 104 or the client computing device 106. The response may be a meeting confirmation that may be sent to each of the associated users that includes a time of the meeting and a list of the meeting participants, among other information. The appropriate response may be based on the received request. As an example, if the request is an email, then the response may be an email. If the request is a text message, then the response may be a text message.
The calendar comparison application includes a sharing module 210 for sharing calendar information with other users of the calendar comparison system 100 and guests not having a user account with the calendar comparison system 100. The user may set the viewing level at a variety of different privacy levels. As an example, each of the approved contacts may be allowed to view the calendar information for the user. As another example, approved contacts of approved contacts also may be allowed to view the calendar information for the user. As an additional example, viewers having a same email domain as approved contacts may be allowed to view the calendar information for the user. Even further, anyone may be allowed to view the calendar information for the user.
As an example, a user using the client computing device 104 may generate a unique URL using the sharing module 210 that represents the calendar information of the user and share the unique URL. As an example, the calendar information may be shared by sending the URL https://approvedcontact.com/Guest.aspx?pv=123456, where “123456” represents a unique identifier for the user. This URL may be shared with users associated with the calendar comparison application 120 and guests of the calendar comparison application that do not have a user account. Other users and guests may retrieve the URL to view a display of calendar information of the user. This display of calendar information allows the viewer to view free and busy times for a particular timeframe, e.g., thirty days, and the viewer may view the calendar information based on any time zone including the viewer's current time zone or another time zone.
The calendar comparison application 120 includes a user interface module 212. The user interface module 212 receives requests or other communications from the client computing device 104 or the client computing device 106 and transmits a representation of requested information, user interface elements, and other data and communications to the client computing device for display on the display 126 or 136. As an example, the user interface module 212 generates a native and/or web-based graphical user interface (GUI) that accepts input and provides output by generating content that is transmitted via the communications network 108 and viewed by a user of the client computing device 104 or 106. The user interface module 212 may provide realtime automatically and dynamically refreshed information to the user of the client computing device 104 or 106 using Java, Javascript, AJAX (Asynchronous Javascript and XML), ASP.NET, Microsoft .NET, and/or node.js, among others. The user interface module 212 may send data to other modules of the calendar comparison application 120 of the calendar comparison server 102, and retrieve data from other modules of the calendar comparison application 120 of the calendar comparison server 102 asynchronously without interfering with the display and behavior of the client computing device 104 or 106. As an example, data may be retrieved using XMLHttpRequest objects or using WebSockets.
FIG. 3 illustrates an example table of the database 110 of the calendar comparison system 100 according to an example embodiment. As shown in FIG. 3, each row of the table may store information regarding a user of the calendar comparison system 100. FIG. 3 shows that the database 110 may store a unique identifier (ID) that represents each user, an email address for each user, name information for each user, a telephone number for each user, a list of approved contacts for each user, and a list of banned contacts for each user. In addition, the database 110 may store additional information for each user such as social network information, video conferencing application contact information, fingerprint information, voice recognition information, and other information.
FIG. 4 illustrates a flowchart of a process 200 for providing a calendar comparison according to an example embodiment. In a first step 402, the client computing device 104 transmits a registration request to the calendar comparison server 102 and the calendar comparison server 102 receives the registration request. The registration request may include user information associated with a first user.
In a next step 404, the calendar comparison server 102 may send a response to the registration request to the client computing device 104 including a verification message including a one-time use URL that is used to confirm that the first user is registered with the calendar comparison server 102. When the one-time use URL is selected by the first user, the calendar comparison server 102 is able to confirm the identity of the first user. In a next step 206, the client computing device 106 transmits a registration request to the calendar comparison server 102 and the calendar comparison server 102 receives the registration request. The registration request may include user information associated with a second user.
In a next step 408, the calendar comparison server 102 may send a response to the registration request to the client computing device 106 including another verification message with a one-time use URL that is used to confirm that the second user is registered with the calendar comparison server 102. When the one-time use URL is selected by the second user, the calendar comparison server 102 is able to confirm the identity of the second user.
In a next step 410, the client computing device 104 may send a calendar invitation to share calendars to the calendar comparison server 102 and the calendar comparison server 102 receives the calendar invitation and forwards information associated with the calendar information to the client computing device 106. In one embodiment, the calendar invitation from the first user may include a list of contacts or users such as the second user. Each of the contacts and users is invited to accept or deny the calendar invitation. As an example, the second user may use the client computing device 106 to accept or deny the calendar invitation and send a response to the calendar comparison server 102. These users become “approved contacts.” If the client computing device 106 accepts the calendar invitation, then the first user and the second user may share calendar information and schedule meetings and appointments with one another.
In a next step 412, the client computing device 104 or the client computing device 106 or another device may send an automated calendar comparison request to the calendar comparison server 102 that includes a period of time, e.g., one hour. The automated calendar comparison request may identify at least two users. In an exemplary embodiment, the automated calendar comparison request may be one of a telephone call, a video conference, a voice over IP communication, interactive voice response (IVR), an email, a text message, a web interface, and an application programming interface (API) communication. For each user identified in the automated calendar comparison request, the calendar comparison server 102 confirms that the user is an approved contact and/or has permitted calendar sharing with the user making the request. If the user has permitted calendar sharing with the user making the request, then the user is included in the automated calendar comparison request. Based on the calendar information for the included users, the calendar comparison server 102 determines a list of open times (e.g., three different times) for the period of time in a particular time frame, e.g., thirty days, a week. This list of open times may be based on the rule information described herein.
In one embodiment, the calendar comparison server 102 transmits the list of open times to the sender of the automated calendar comparison request, among other users. Thus, the calendar comparison server 102 may transmit the list of open times to the client computing device 104 and/or the client computing device 106. In another embodiment, the calendar comparison server 102 selects a best time of the open times, schedules the meeting at the best time, and transmits a confirmation to each of the users. The best time may be a first time when each of the users is available during business hours, e.g., 1 p.m. next Tuesday.
This may provide significant benefits to each of the users. Rather than the conventional calendar comparison techniques that involve manual work and a significant amount of wasted communication, the calendar comparison server 102 is able to automatically determine a best time or a list of best times that are suited for the users.

FIG. 9 shows another screenshot of a user interface 900 provided by the calendar comparison application 120 and displayed on the display 126 or 136 of the client computing device 104 or 106. The screenshot shown in FIG. 9 shows a list of contacts associated with a user and their contact information. The user interface allows the user to view approved contacts, banned contacts, and other types of contacts.
FIG. 10 shows another screenshot of a user interface 1000 provided by the calendar comparison application 120. The screenshot shown in FIG. 10 shows a display of calendar information for a particular user that may be shared via a unique URL. As an example, the calendar information may be shared by sending the URL https://approvedcontact.com/Guest.aspx?pv=123456, where “123456” represents a unique identifier for the user. This URL may be shared with users associated with the calendar comparison application 120 and guests of the calendar comparison application that do not have a user account. This display of calendar information allows the viewer to view open and busy times for a particular timeframe and the viewer may view the calendar information based on any time zone including the viewer's current time zone or another time zone.
