Abstract

A system and method combine mobile information device, server computer, and a task manager to provide the mobile information device user to retrieve the information corresponding to the user'"'"'s current location from a server computer over Internet. The task manager schedules search events and chooses geographic search area to retrieves user'"'"'s nearby information along the travel path. The task manager is accessible to an automatic positioning system to track user'"'"'s mobile position and to predict the future travel path. The task manager use the query turn-around time to plans and schedule before reach the next desired area and further uses historical search criteria to reduce the search results of current search criteria before transmitting the final results through the wireless communication bottleneck.

Claims

34. A method for continuously searching local information comprise steps of

receiving one or more inputs from user;

parsing said one or more inputs and constructing search task, wherein said search task describing a criteria of search topic and a geographic search area related to a search schedule and a moving object;

scheduling one or more search activities according to said search task in a search task database;

executing said one or more search activities by querying server computer according to said search schedule;

searching a geo-coded topical database for queried said one or more search activities; and

transmitting search results of said searching step to client computer over wireless telecommunication channel, and rescheduling or terminating said one of said one or more search activities after being executed, wherein said rescheduling do said scheduling step at different time, place, and environment.

53-1. A computer system comprising one or more computers connected to a computer network, and computer instructions executed by the computer system for performing the acts in claim 1.

54-2. A computer-readable storage medium encoded with computer instructions for performing the acts in claim 1.

55. A continuous local information searching system, comprising:

a server computer having a server transmitter,

an informational database containing topical data and geographic data, said informational database accessed by said server computer,

a searching task manager configured to receive a search request from user, schedule one or more search queries according to said search request, and query said server computer with said one or more search queries, said search request describing a search topic and one or more geographic areas within which said desired search topic is to be located, said one or more geographic areas relate to a moving object and said schedule, and

a mobile computer having a mobile receiver configured to receive the result of said query from said server transmitter.

56. The system as claimed in claim 55, wherein said search query is response to said search request, including a criteria for said search topic and a subset of said one or more geographic areas where said search topic is to be located.

57. The system as claimed in claim 56, wherein said searching task manager further comprises a searching area planning subsystem to plan for said subset of one or more geographic areas of said query.

58. The system as claimed in claim 57, wherein said searching area planning subsystem determines said one or more geographic areas based on information provided from one or more supporting subsystems.

59. The system as claimed in claim 58, wherein said supporting subsystem is a query turn-around time prediction subsystem.

60. The system as claimed in claim 58, wherein said supporting subsystem is a planned travel route subsystem that provides one or more planned travel routes and determines the planned travel route where the moving object is on.

61. The system as claimed in claim 58, wherein said supporting subsystem is a moving condition subsystem that provides the movement of the moving object.

62. The system as claimed in claim 61, wherein said movement of the moving object is selected from the following group:

a current position, a direction of motion, a speed of motion, and a moving signal.

63. The system as claimed in claim 62, wherein said moving signal is selected from the following group:

a direction change signal, an acceleration signal, and a deceleration signal.

64. The system as claimed in claim 63, wherein said supporting subsystem is a dynamic constraint subsystem that provides dynamic constraint information.

65. The system as claimed in claim 64, wherein said dynamic constraint information is selected from the following group:

an indication of remaining energy, a rate of energy consumption, and a resistance of movement.

66. The system as claimed in claim 65, wherein said resistance is selected from the following group:

a road condition, a weather condition, and a weight loading.

67. The system as claimed in claim 62, wherein said current position determined by an automatic positioning system (APS).

68. The system as claimed in claim 67, wherein said automatic positioning system is a Global Positioning System.

69. The system as claimed in claim 67, wherein said automatic positioning system is a network based positioning system, wherein the location is determined via triangulation.

70. The system as claimed in claim 56, further comprising a query synthesis subsystem for synthesizing one or more instructions of said one or more queries.

71. The system as claimed in claim 70, wherein said query synthesis subsystem further reduce said subset of one or more geographic areas of the query to be scheduled by removing the overlapping with the subset of one or more geographic areas of scheduled query.

72. The system as claimed in claim 55, wherein said searching task manager further comprises a search scheduling subsystem that provides a trigger condition for said one or more queries.

73. The system as claimed in claim 72, wherein said trigger condition is selected form one or more of the following group:

arriving at a time, elapsing a period of time, approaching to a distance, arriving a geographic location, and entering a geographic area.

74. The system as claimed in claim 73, wherein said trigger condition is a function of one or more factors selected from the following:

.

a moving condition of the moving object,

a predefined travel route of die moving object,

a dynamic constraint,

a user preference, and

a predicted query turn-around time.

75. The system as claimed in claim 55, wherein the transmit order of said one or more search results is determined by the distance between the position of said moving object to one of said one or more search result.

76. The system as claimed in claim 55, wherein the transmit order of said one or more search results is determined by whether said moving object is approaching or leaving one of said one or more search results.

77. The system as claimed in claim 55, wherein said remote computer presents said one or more search results audibly or visually.

78. The system as claimed in claim 77, wherein said remote computer presents said one or more search results in an order related to the distance between the position of said moving object and one of said one or more search result.

79. The system as claimed in claim 77, wherein said remote computer presents said one or more search results in an order related to whether said moving object is approaching or leaving one of said one or more search results.
