Description of the Invention: [Technical Field] The present invention provides a method for reminding a user of an appointment, and more particularly to a method for reminding a user of an appointment based on a travel time. [Prior Art] Global The Global Positioning System (GPS) is the most basic function built into the personal navigation device known to the public, and is widely used in in-vehicle personal navigation devices. A common function of personal navigation devices is to provide a map database analysis to generate appropriate navigation commands and display the instructions on the screen of the personal navigation device. This type of personal navigation device is typically attached to the front dashboard of the vehicle with a suction cup or other type of fastening element. A personal navigation device generally refers to a device that directs a user to a predetermined destination. Such devices typically have a built-in system that can receive positioning data, such as a global clamp system receiver, or may only be in communication with a receiver that receives the positioning data function. There are several methods for analyzing data in such devices. One is a data that can be self-operated, and the other is a remote server that provides a path data calculation function. The server calculates and provides navigation data. Or the device not only has its own computing function, but also can be connected to the remote server to receive the computing data of the server. The handheld GPS global navigation device does not need to be completely fixed in the vehicle, but allows the user 4 201024679 to be easily installed or removed. Such personal navigation devices typically (but not necessarily) have built-in GPS antennas, navigation software and maps, and can draw and display maps themselves, which can be a completely independent device. Traditionally, people are accustomed to using paper or electronic calendars to manage future appointments. The electronic calendar can remind the user in advance before the scheduled start of the appointment. If the date of the appointment is far from the current location of the user, the user wishes to be reminded in advance to make a timely departure to meet on time, but does not wish to arrive too early. location. When the user is not familiar with the surrounding environment of the date of the appointment, it is more difficult to make appointments on time. Automated electronic calendars built into computers, personal digital assistants (PDAs) or smart phones often only record the location of the appointment, but do not automatically or dynamically consider the time required to travel to the appointment location. . In a typical dating system, it is up to the user to decide how long before the appointment begins to be alerted. However, the dating system cannot accurately know or predict the location of the user, so the time required to travel to the appointment location will not be considered. The Dating System also does not have enough information to calculate the time required for the user to travel to the appointment location, so the user cannot be reminded at the appropriate time. 5 201024679 Users of the prior art dating system can estimate the time required to travel to the date of the appointment based on their location, provided that the user is familiar with the surrounding environment of the appointment and that the estimated journey time will not change on the road. . SUMMARY OF THE INVENTION The present invention provides a method for reminding a user of an appointment, comprising receiving an input to an appointment time and an appointment location in a personal navigation device operated by a user; determining a current location of the personal navigation device; The user's preferred route to the appointment location; calculate one of the estimated travel times required to use the user's preferred route from the current location to the appointment location; determine a reminder based on the estimated travel time and the appointment time a moment; and reminding the user of the message related to the appointment at the reminder moment. The present invention further provides a method for reminding a user of an appointment, comprising receiving an input to an appointment time and an appointment location in a personal navigation device operated by a user; determining a current location of the personal navigation device; determining the appointment location a parking space situation nearby, wherein the parking space condition includes a parking lot location, the number of empty parking spaces in the parking lot, and the time required to travel from the parking lot to the dating place; determining the number according to the number and location of the empty parking space One of the estimated travel time required by the user to travel to the appointment location from the current location; a reminder 201024679 is determined based on the estimated travel time and the appointment time; and the appointment is communicated to the user at the reminder time. The present invention further provides a method for reminding a user of an appointment, comprising receiving an input to an appointment time and an appointment location in a personal navigation device operated by a user, wherein the appointment location is a changeable location; determining the individual The current location of the navigation device; determining an up-to-date appointment location; determining an estimated travel time required by the user to travel to the latest appointment location from the current location; determining a reminder time based on the estimated travel time and the appointment time; And inform the user of the appointment at the reminder time. [Embodiment] Please refer to Fig. 1, which is a block diagram of a person navigation device 10 of the present invention. The personal navigation device 10 includes a processor 12, a GPS module 14, an input terminal 16, an output terminal 18, and a memory 20. The GPS module 14 can receive information on the current location of the personal navigation device 10. The input terminal ® 16 can be a control button or a touch panel, and the output terminal 18 can be a loudspeaker or a display screen. The memory 20 includes a firmware 22 that the processor 12 can execute to operate the personal navigation device 10. Memory 20 memory contains map data 24 of general map information, such as information related to roads, addresses, and travel routes. For each appointment entered into the personal navigation device 10, the corresponding storage data 26 is stored in the memory 20. Appointment information 26 includes appointment time, date of appointment, and time to prepare for buffering. The preparation buffer time is related to the time the user wishes to reserve in order to prepare for the appointment. Dating information 201024679 26 also includes, love route information 28, which shows that when the user goes from one place to another -: point, the route M is used to navigate the farmer's house. According to these U still = choose St: go to the destination The time required for the land, however, makes the line slightly unemployed. When the user selects the second hexagram 20, the corresponding selected route data 30 is stored. ^ Calculate the time required to travel each route, and also in memory 20: Enter historical data related to travel time32. The % parking data indicates whether there is a parking lot near the date of the appointment. Lu Ming refers to Fig. 2'. Fig. 2 illustrates the preferred travel route for different segments of the route. For example, a user who prefers a point to a point of interest prefers to drive on a speeding road, which is typically (7) minutes. : For the section from point B to point C, the user also prefers to drive on the highway, which is usually 8 minutes. For the segments from point c to point D, the user prefers to take the ferry' and the boat trip is usually 4G minutes. For the section from point D to point E, the user prefers to take the train, and the train ride is usually 17 minutes. The more the personal navigation device 10 can more effectively estimate the arrival time, the more the relevant information about the user's past and driving time can be provided, so the historical data 32 is updated to respond. The historical journey time will be more accurate if you add the time and date of the demander. Another: the use of the face 'right can not provide historical information, and the user has not yet lost their journey time' personal navigation device i may need to calculate their own scheduled time 201024679 estimated journey time. For example, the default estimated travel time can be determined by dividing the total distance of all travel segments by the current travel speed. Since the actual travel speeds on different break zones are not exactly the same, the default travel time is less accurate than the historical travel time. If the personal navigation device 1 is unable to provide the estimated travel time required to travel to the destination, the user can enter an estimated travel time for certain sections of the route. After several trips, the personal navigation device 10 can know the driving time of these routes and store the data related to the itinerary into the historical data 32 in the memory 20. The processor 12 of the U-NAVIG navigation device will determine when and how to wake up the upcoming appointment based on a number of factors. First, the appointment time, the date of the appointment, and the current location of the user are important information. Since the user may travel to other locations before the appointment, the personal navigation device 1 must periodically monitor the user's current location and then decide when to remind the user of the upcoming appointment. Also consider the preparation of the buffer time' to allow the user to have extra time to prepare for the contract. In order to accurately estimate the travel time required to travel to the dating site, the personal navigation device 10 also needs to consider the possible route to the dating site, = route (four) speed limit, ride (four) no (four) segment of the journey time calendar, the user's preferred travel Routes (such as highways, toll roads, etc., preferred by h users (such as cars, walking, bicycles, trains, buses, or (d) using several modes of transportation), parking spaces 9 201024679 status, and parking spaces and dating locations The distance between the user navigation device 10 and the personal navigation device 10 will continuously calculate the time required to travel to the appointment site until the time point when the user needs to leave, that is, the personal navigation device 10 needs to be reminded at this time. The user's upcoming appointment. When the user is notified of the upcoming appointment at this reminder moment, the personal navigation device 10 can provide a navigation instruction to the appointment location according to the user's request or automatically. On the way to the appointment location, personal navigation The device 10 can also provide a journey status to let the user know the current progress. When the progress is exceeded, the user can use extra time to handle other matters, such as fueling the car, visiting friends, or going to the store to shop. In the backward progress, the user can remind the other participants of the appointment in advance. The change caused by being late is reduced. When the user arrives at the appointment site, the personal navigation device 10 can display other information or prompts, such as an appointment of other participants' names or items or documents required in the appointment, etc. The personal navigation device 10 The visual or sound effect reminder can be provided through the output 18. Since the condition of the parking space changes at any time, the personal navigation device 10 can let the user know which parking lot is available near the date of the appointment, the number of empty parking spaces, and the parking lot. The time required for the appointment location. The personal navigation device 10 can receive instant messages related to parking spaces, weather or traffic conditions via the Internet, broadcast channels or other sources. Instant parking 201024679 The message shows the number of parking spaces in the parking lot. Instant traffic messages show accidents in traffic accidents, road blockades, or plugs Traffic conditions such as road sections. Instant weather messages indicate heavy rain, flooding, or blizzards. Weather and traffic conditions affect the time required to travel to the destination, so the invention can correct the estimated journey time accordingly. 3, Figure 3 is a schematic diagram of the parking data 34 _ in the memory 20 memory. This information can help the user to determine the parking location and estimated total journey time. For example, if you go to the zoo, there are 142 parking lots in the zoo. There is an empty parking space, and the parking lot and the zoo are about 3 minutes walking distance. If you go to the shopping center, there are 40 empty parking spaces in the parking lot of the shopping center, and the parking lot and the shopping center are about 5 minutes walking distance. There is only one minute walk between the beach parking lot A and the beach, but there is no parking space at this time; however, there are 40 empty parking spaces in the parking lot B of the beach, but the parking lot B and the beach are about to go. 10 minutes. In addition to the current status of parking spaces, other factors such as traffic and weather conditions will also affect the journey time, so these conditions need to be considered when calculating the estimated journey time. Due to the considerable variation in the estimated travel time from the current location of the user to the date of the appointment, the estimated journey time must be recalculated periodically. The invention also encompasses other embodiments, such as a user or conference participant. 11 201024679 The appointment location or time can be changed for any reason. In this case, the updated appointment location may be provided by the user or personal navigation device 10, and the personal navigation device 10 may then recalculate and update the estimated travel time. At the same time, the appointment time can be updated in real time. The reminder message related to the update of the appointment location or the update of the appointment time can be received in the form of a short message, and the appointment information stored in the calendar is updated according to the received newsletter. When the user knows that the appointment has changed, they can also update the appointment location or appointment time. In another embodiment of the present invention, two or more users may be moving toward the other party, and the personal navigation device 10 may track the location of each user and perform a local search for the surrounding area where the user expects the meeting location. In order to allow one of the users to reserve a date near the expected meeting location at the last minute. Referring to FIG. 4, a flow chart of FIG. 4 illustrates a method for reminding a user of an appointment, including the following steps: ® Step 100: The user inputs an appointment time, an appointment location, and a preparation buffer time, and deposits the information into the present invention. The date of the memory 20 is 26. Step 102: The personal navigation device 10 determines the current location of the user and the current dating location based on the map data 24 and the GPS module 14 stored in the memory 20. Step 104: The personal navigation device 10 utilizes the user's preferred route information 28 and the GPS module 14 to generate a suggested route. 12 201024679 Step 106: The personal navigation device 10 asks the user whether to change the suggested route; if the user wants to change the suggested route, step 108 is performed; if the user does not change the suggested route, step 110 is performed. Step 108: The user selects a different route. Step 110: The personal navigation device 10 asks the user whether to stop near the appointment location; if the user needs to park near the appointment location, step 112 is performed; if the user does not need to park near the appointment location, step 114 is performed. Step 112: The user selects a parking lot based on the parking data 34 and the current parking status. Step 114: The processor 12 of the personal navigation device 10 calculates the current location of the personal navigation device 10 based on the required driving time, parking time, and other variables such as traffic and weather. Step 116: Estimation required to travel to the current dating location Journey time. The processor 12 generates a reminder moment based on the estimated travel time, the preparation buffer time, and the appointment time to inform the user of the upcoming appointment at this point in time. Step 118: Determine whether the reminder moment has been reached; if the reminder moment has been reached, perform step 122; if the reminder moment has not yet arrived, perform step 120. Step 120: Determine whether the appointment location has changed; if the appointment location has changed, go to step 114; if the appointment location has not changed, go to step 118. Step 122: Remind the user of the scheduled appointment and provide instructions on how to proceed to the appointment location.
