Description

提醒使用者未來約會之方法Remind users how to date in the future

本發明提供一種提醒使用者約會之方法，尤指一種依據旅程時間來提醒使用者約會之方法。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 the travel time.

全球定位系統(Global Positioning System,GPS)已是社會大眾所知內建於個人導航裝置的最基本功能，且廣泛應用於車內個人導航裝置。個人導航裝置常見的功能就是提供一地圖數據庫分析以產生適當的導航指令，並將該指令顯示於個人導航裝置的螢幕上。這類型的個人導航裝置通常以吸盤或其它種類的固定元件固定在交通運輸工具的前儀表板上。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.

個人導航裝置泛指一種能引導使用者前往預定目的地的裝置。這類裝置通常內建一組可接收定位數據的系統，例如全球定位系統接收器，也可能是僅和一有接收定位數據功能的接收器通訊連結。這類裝置分析數據的方法有數種，其一為可自行運算所經路線的數據、其二為連線至可提供路徑數據運算功能的遠端伺服器，由該伺服器運算並提供導航資料、或者是該裝置不但有自行運算功能，同時也能連線到遠端伺服器接收該伺服器的運算數據。手持式全球定位系統個人導航裝置不需完全固定在交通運輸工具內，而是讓使用者能輕易安裝或拆卸。這類個人導航裝置通常(但非必然)內建有全球定位系統天線、導航軟體與地圖，並可自行繪製、顯示地圖，幾可為一完全獨立運作的裝置。A personal navigation device generally refers to a device that can guide a user to a predetermined destination. Such devices typically have a built-in system that can receive positioning data, such as a global positioning system receiver, or may only be in communication with a receiver that has the capability to receive positioning data. 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 can be connected to a path data computing 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 global positioning system personal navigation device does not need to be completely fixed in the transportation vehicle, but can be easily installed or disassembled by the user. Such personal navigation devices usually (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.

傳統上，人們習慣運用紙張或電子日曆來管理未來約會。電子日曆能在約會開始一預定時間之前事先提醒使用者。Traditionally, people are accustomed to using paper or electronic calendars to manage future appointments. The electronic calendar can alert the user before the scheduled start of the appointment.

若約會地點和使用者目前所在地距離很遠，使用者希望能夠事先被提醒，才能及時出發以準時赴約，然而又不希望太早抵達約會地點。當使用者不熟悉約會地點的週遭環境時，要剛好準時赴約也變得更為困難。If the date of the appointment and the current location of the user are far away, the user hopes to be reminded in advance to make a timely departure to meet on time, but does not wish to arrive at the appointment site too early. 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.

電腦、個人數位助理(personal digital assistant，PDA)，或智慧型手機(smartphone)內建之自動電子行事曆往往僅會紀錄約會地點，卻不會自動或動態地考量前往約會地點所需之時間。Automated electronic calendars built into computers, personal digital assistants (PDAs), or smart phones often only record dating locations, but do not automatically or dynamically consider the time required to travel to a dating location.

在典型的約會系統中，由使用者自行決定在約會開始前多久時間被提醒。然而，約會系統無法準確得知或預知使用者所在位置，因此不會考量前往約會地點所需之時間。約會系統亦無足夠資訊來計算出使用者前往約會地點所需之時間，因此無法適時提醒使用者。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. Therefore, the user cannot be reminded at the appropriate time.

先前技術約會系統之使用者可依據其所在地自行估計前往約會地點所需之時間，然而前提是使用者需十分熟悉約會地點的週遭環境，而且路上不會遇上意外而改變預估旅程時間。Users of prior art dating systems can estimate the time required to travel to a dating location based on their location, provided that the user is familiar with the surrounding environment of the meeting location and that the estimated journey time is not changed on the road.

本發明另提供一種提醒使用者約會之方法，包含接收輸入至由一使用者所操作之一個人導航裝置內之一約會時間和一約會地點，其中該約會地點為一可變動之地點；決定該個人導航裝置之目前位置；決定一最新約會地點；判斷當該使用者從該目前位置前往該最新約會地點時所需之一預計旅程時間；依據該預計旅程時間和該約會時間來決定一提醒時刻；以及於該提醒時刻將該約會告知該使用者。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.

請參考第1圖，第1圖為本發明中一個人導航裝置10之方塊圖。個人導航裝置10包含一處理器12、一GPS模組14、一輸入端16、一輸出端18，以及一記憶體20。GPS模組14可接收個人導航裝置10目前所在位置之資訊。輸入端16可為控制按鍵或觸控面板，而輸出端18可為一擴音器或一顯示螢幕。記憶體20包含一韌體(firmware)22，處理器12可執行韌體22以運作個人導航裝置10。記憶體20內存包含概略地圖資訊之地圖資料24，例如相關於道路、地址和行進路線之資料。針對每一筆輸入至個人導航裝置10之約會，記憶體20內存有相對應之約會資料26。約會資料26包含約會時間、約會地點，以及準備緩衝時間。準備緩衝時間相關於使用者為了準備約會而希望預留之時間。約會資料26亦包含偏愛路線資料28，說明了使用者由某一地點前往另一地點時通常使用的路線。個人導航裝置10可依據這些使用者之偏愛路線來計算出前往目的地所需之時間，然而使用者仍可選擇其它路線而不使用其偏愛路線。當使用者選定一路線後，記憶體20內會存入相對應之選定路線資料30。為了更精確地算出行走各路線所需之時間，記憶體20內亦可存入相關於旅程時間之歷史資料32。停車資料34表明了約會地點附近是否有停車場所。Please refer to FIG. 1. FIG. 1 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. The memory 20 stores map data 24 containing summary map information, such as information relating 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 preparation buffer time. The preparation buffer time is related to the time the user wishes to reserve in order to prepare for the appointment. Appointment information 26 also includes preference route information 28, which describes the route that is typically used when a user travels from one location to another. The personal navigation device 10 can calculate the time required to travel to the destination based on the preferred route of the users, but the user can still select other routes without using the preferred route. When the user selects a route, the corresponding selected route data 30 is stored in the memory 20. In order to more accurately calculate the time required to travel each route, the historical data 32 relating to the travel time may also be stored in the memory 20. Parking information 34 indicates whether there is a parking lot near the date of the appointment.

請參考第2圖，第2圖說明了針對一路線之不同區段一使用者之偏愛行進路線。舉例來說，針對A點至B點的區段，使用者偏好在高速公路上開車，而車程通常為10分鐘。針對B點至C點的區段，使用者同樣偏好在高速公路上開車，而車程通常為8分鐘。針對C點至D點的區段，使用者偏好搭乘渡輪，而船程通常為40分鐘。針對D點至E點的區段，使用者偏好搭乘火車，而火車車程通常為17分鐘。Please refer to FIG. 2, which illustrates a preferred travel route for a user of different segments of a route. For example, for segments from point A to point B, the user prefers to drive on the highway, which is typically 10 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 section from point C to point D, the user prefers to take the ferry, which is usually 40 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.

若能提供越多相關於使用者過去行程和開車時間之歷史資料，個人導航裝置10更能有效地估計抵達目的地所需之時間，因此會更新歷史資料32以因應。若另加考慮使用者旅行的時間和日期，歷史旅程時間將會更準確。另一方面，若無法提供歷史資料，而使用者尚未輸入其自行預估之旅程時間，個人導航裝置10可能需要自行計算出其內定之預計旅程時間。舉例來說，內定之預計旅程時間可藉由將所有行進區段之總距離除以目前行進速度來求得。由於在不同行進區段上之實際行進速度不會完全相同，內定之預計旅程時間和歷史旅程時間相比較為不準確。If more historical data relating to the user's past trip and driving time can be provided, the personal navigation device 10 can more effectively estimate the time required to arrive at the destination, and thus the historical data 32 is updated to respond. If you consider the time and date of the user's travel, the historical journey time will be more accurate. On the other hand, if the historical data cannot be provided and the user has not entered his own estimated travel time, the personal navigation device 10 may need to calculate its own estimated travel 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 travel segments will not be exactly the same, the estimated travel time is less accurate than the historical travel time.

若個人導航裝置10無法提供前往目的地所需之預計旅程時間，使用者可針對路線中某些區段輸入預計旅程時間。在數次旅程後，個人導航裝置10即可得知這些路線的開車時間，並將相關於此行程之資料存入記憶體20內之歷史資料32。If the personal navigation device 10 is unable to provide the estimated journey time required to travel to the destination, the user may enter an estimated journey 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.

個人導航裝置10之處理器12會依據一些因素來決定何時提醒使用者即將來臨的約會。首先，約會時間、約會地點和使用者目前位置是重要資訊。由於使用者在約會之前可能會前往其它場所，個人導航裝置10必須定期地監測使用者目前最新位置，再依此決定何時提醒使用者即將來臨的約會。另外亦需考慮準備緩衝時間，以讓使用者有額外時間為約為作準備。為了能準確估計前往約會地點所需的旅程時間，個人導航裝置10也需考量前往約會地點之可能路線、這些路線的時速限制、針對路線中不同區段之旅程時間的歷史統計、使用者之偏愛行進路線(例如高速公路、收費道路或景觀道路等)、使用者之偏愛交通方式(例如汽車、步行、腳踏車、火車、公車，或同時使用數種交通方式)、停車位狀況，以及停車位和約會地點之間的距離。The processor 12 of the personal navigation device 10 will determine when to alert the user to an 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 10 must periodically monitor the user's current location and then decide when to remind the user of the upcoming appointment. It is also necessary to consider the preparation of the buffer time so that the user has extra time to prepare for the appointment. In order to accurately estimate the travel time required to travel to a dating location, the personal navigation device 10 also needs to consider possible routes to the dating location, speed limits for these routes, historical statistics for travel times for different segments of the route, and user preferences. Routes (such as highways, toll roads, or landscape roads), user preferences (such as cars, walking, bicycles, trains, buses, or several modes of transportation), parking conditions, and parking spaces and The distance between the dating locations.

在使用者移動過程中，個人導航裝置10會不斷重複計算前往約會地點所需之時間，直到接近使用者需要動身之時間點，也就是個人導航裝置10需要在此時間點提醒使用者即將來臨的約會。當在此提醒時刻告知使用者即將來臨的約會時，個人導航裝置10可依據使用者的要求或自動提供前往約會地點之導航指示。在前往約會地點的途中，個人導航裝置10亦可提供旅程狀況以讓使用者得知目前的進度。在超過進度時，使用者可利用多餘的時間來處理其它事務，例如替車子加油、拜訪朋友，或是前往商店購物。在落後進度時，使用者可事先提醒約會之其它參與者，以減少因遲到所造成的不變。當使用者抵達約會地點後，個人導航裝置10可顯示其它資訊或提示，例如約會其它參與者的名字或約會中所需要的物品或文件等。個人導航裝置10可透過輸出端18來提供視覺或音效提醒。During the user's movement, the personal navigation device 10 will repeatedly 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 remind the user of the upcoming time at this time. appointment. When the user is notified of an upcoming appointment at this reminder moment, the personal navigation device 10 can provide a navigation indication to the appointment location based on the user's request or automatically. On the way to the date of the appointment, the personal navigation device 10 can also provide the status of the trip 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. When the progress is behind, the user can remind the other participants of the appointment in advance to reduce the change caused by the late arrival. When the user arrives at the appointment location, the personal navigation device 10 can display other information or prompts, such as an appointment for the names of other participants or items or documents needed in the appointment. The personal navigation device 10 can provide a visual or sound effect reminder via the output 18.

由於停車位的狀況隨時會改變，個人導航裝置10可讓使用者得知在約會地點附近哪個停車場有空位、空停車位的數目，以及從停車場前往約會地點所需之時間。Since the condition of the parking space changes at any time, the personal navigation device 10 allows the user to know which parking lot is available near the date of the appointment, the number of empty parking spaces, and the time required to travel from the parking lot to the date of the appointment.

個人導航裝置10可透過網路、廣播頻道或其它來源來接收相關於停車位、天候或交通路況的即時訊息。即時停車位訊息顯示了停車場內可停車位的數目。即時交通訊息顯示了車禍意外、道路封鎖，或塞車路段等交通路況。即時天候訊息顯示了大雨、淹水，或暴風雪等情形。天候和交通路況皆會影響前往目的地所需之時間，因此本發明可依此修正預計旅程時間。The personal navigation device 10 can receive instant messages related to parking spaces, weather or traffic conditions via a network, broadcast channel or other source. The instant parking space message shows the number of parking spaces available in the parking lot. Instant traffic messages show traffic accidents such as accidents, road closures, or traffic jams. Instant weather messages show heavy rain, flooding, or blizzards. The weather and traffic conditions all affect the time required to travel to the destination, so the present invention can correct the estimated journey time accordingly.

請參考第3圖，第3圖為記憶體20內存之停車資料34的示意圖。這些資料可幫助使用者決定停車地點和估計總旅程時間。舉例來說，若前往動物園，動物園之停車場內尚餘142個空停車位，而且停車場和動物園之間約3分鐘步行距離。若前往購物中心，購物中心之停車場內尚餘40個空停車位，而且停車場和購物中心之間約5分鐘步行距離。若前往海灘，海灘之停車場A和海灘之間僅隔1分鐘步行距離，但此時並無空停車位；然而，海灘之停車場B內尚餘40個空停車位，但停車場B和海灘之間大約要走10分鐘。Please refer to FIG. 3, which is a schematic diagram of the parking data 34 in the memory 20 memory. This information helps the user decide where to park and estimate the total journey time. For example, if you go to the zoo, there are 142 empty parking spaces in the parking lot of the zoo, 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 about 5 minutes walking distance between the parking lot and the shopping center. If you go to the beach, the beach parking lot A and the beach are only 1 minute walk away, 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 between the parking lot B and the beach It takes about 10 minutes.

除了停車位的現況外，交通和天候狀況等其它變動因素亦會影響旅程時間，因此在計算預計旅程時間時皆需考量這些情況。由於影響從使用者目前所在地前往約會地點之預計旅程時間的變動因素相當多，因此必須定期地重新計算預計旅程時間。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 journey time from the current location of the user to the date of the appointment, the estimated journey time must be recalculated periodically.

本發明亦包含其它實施例，例如使用者或會議參與者可能會因故更改約會地點或時間。在此種情形下，可由使用者或個人導航裝置10提供更新之約會地點，個人導航裝置10再依此重新計算並更新預計旅程時間。同時，約會時間亦可即時更新，相關於更新約會地點或更新約會時間之提醒訊息可用簡訊的形式來接收，並依據接收到之簡訊來更新行事曆中儲存之約會資料。當使用者得知約會有所變動時，也可以自行更新約會地點或約會時間。在本發明另一實施例中，兩位或多位使用者可能正朝向對方移動，個人導航裝置10可追蹤每一使用者的位置，並針對使用者預期碰面地點的週邊區域進行局部搜索，以讓其中一位使用者能在最後關頭於預期碰面地點附近預定一約會地點。The invention also encompasses other embodiments, such as a user or conference participant may change the appointment location or time 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 of the user's expected meeting location. Have one of the users be able to book an appointment location near the expected meeting location at the last minute.

請參考第4圖，第4圖之流程圖說明了本發明提醒使用者約會之方法，包含下列步驟：步驟100：使用者輸入約會時間、約會地點及準備緩衝時間，並將這些訊息存入記憶體20之約會資料26。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 stores the message in the memory. Dating information for Body 20 26.
