Personal communication and positioning system
View Patent ↗A location tagged data provision and display system. A personal communication device (PCD) with electromagnetic communication capability has a GPS receiver and a display. The PCD requests maps and location tagged data from data providers and other for display on the PCD. The data providers respond to requests by using searching and sorting schemes to interrogate data bases and then automatically transmitting data responsive to the requests to the requesting PCD.
1. A personal digital communicator comprising:
a display;
a receiver for receiving GPS signals;
a transceiver;
input means for inputting a request for map related information;
a digital processor providing, a means for determining a location of the communicator based on the GPS signals, for commanding transmission of the request for map information, for commanding display on the display related map information responsive to the request, and for commanding display on the display the communicator location with reference to the map related information; and
wherein the processor is configured to determine a selected route;
wherein the processor is configured to command transmission of a request for roadway information for roadways on the selected route;
wherein the processor is configured to process received data responsive to the request for roadway information, the received data including information from condition reporting devices along the route;
wherein the processor is configured to command display of information indicative of the received data responsive to the request for roadway information; and
wherein the processor is configured to maintain a sequential list of condition reporting devices located along the route.
2. The personal digital communicator of claim 1 further comprising a memory, the processor being further configured to store information indicating the selected route.
3. The personal digital communicator of claim 2 wherein the processor is further configured to determine condition reporting devices along the selected route.
4. The personal digital communicator of claim 3 wherein the transmission of a request for roadway information for roadways on the selected route is a transmission of a request for information from condition reporting devices along the selected route.
5. The personal digital communicator of claim 4 wherein the data responsive to the request for roadway information is traffic information.
6. The personal digital communicator of claim 5 wherein the traffic information is current speed information.
7. The personal digital communicator of claim 6 wherein the processor is further configured to use the current speed information to determine travel times.
8. The personal digital communicator of claim 7 wherein the processor is configured to use the current speed information to determine travel times along the selected route.
9. The personal digital communicator of claim 8 wherein the processor is configured to use the current speed information to determine travel times along alternative routes.
10. The personal digital communicator of claim 9 wherein the alternative routes are provided by a user.
11. The personal digital communicator of claim 1 wherein the sequential list is ordered such that a first condition reporting device expected to be encountered along the route is placed first in the list and the last condition reporting device expected to be encountered along the route is placed last on the list.
12. The personal digital communicator of claim 1 wherein the sequential list of condition reporting devices forms a travel list.
