sorry to the moderators in case Iam in the wrong path. I am taking my last class INSY498 and I am working in a project in which I need to pick up a subject and suggest modification in the actual operating system of it. I have a navigation system in my car ECLIPSE Fugitsu Ten
http://carsound.com/articles/publish/printer_282.shtml

when you touch the screen, it gives the exact location, number and street, so my suggestion is when you touch the screen is that it provides the exact location number, street and PLUS TELEPHONE NUMBER, ASSOCIATED WITH THAT NUMBER LOCATION THEN IF YOU TOUCH THE TELEPHONE NUMBER IN THE SCREEN IT SHOULD CONNECT IN CALL WITH THAT NUMBER THROUTH A CEEL PHONE.

For example some times I am in the car if I go to a shopping area and I see the address on the screen but I would like to call them to confirm if they have the product, so I could call them directly from the navigation and cell phone, but if I do not have the phone number that is impossible.


My questions are how can be possible done in a simple diagram? I know that the number can be added to the database in the address number but how could add a cell phone to a navigation system? How I can explain that the phone will do the call with a simple touch in the screen?

NOTICE IT IS ONLY THEORETICAL, IT WILL NOT BE DONE, I JUST WANT TO DRAW A PICTURE AND EXPLAIN THAT IT IS POSSIBLE BE DONE. IF YOU HAVE ANY IDEAS OR LINK AND TIME TO ASNWER IT. I REALLY WILL APRECCIATE IT.

Hmmm....

Are you asking about a future product enhancement by the manufacturer.....

Or about modifying a Nav unit that is in a car already?

Either can be done, but the first is not likely to have the market demand needed to justify the R & D expense, unless it became an incidental benefit to some other product improvement.

Modifying a unit already in a car would be pretty expensive.

In a former career I was involved with the manufacture of first generation touchscreens. Making them work was easy. Making them translucent so you could see the images behind the silkscreened layer of gold was more of a challenge.

In your scenario, I think the biggest issue would be accuracy of the telephone database - that is a much more dynamic set of information than the fairly static set of addresses and roads.

The above doesn't help you with your paper, but I will sleep on it and try to add some constructive comments.

Good Luck,

 

thanks icedancr I apprecciate you help. well the idea is to prove that the actual system can be modify and add some more features and data to the actual sytem. I know that it will not be done in my navigation system car because it implies a lot of money but it is only a part a homework. As a final result it will not be done anything in the hardware, it is only a proposal. That I really want to propose is to add to the database the phone number according to the number address and modify the gps navigation hardware to connect to a cell phone (universal connector). It does not matter the cost, becasue it is just a proposal. I break down the actual system link provide by image

and here is where I need probably more help.where do i add the database phone, the touch screen modification in the diagram? I will aprecciate your help, thanks for you interest in my subject.

 

Got 3 minutes, packing for a Honolulu flight, would be very bad Mojo to miss it...

Consider this a TTT so that perhaps a younger C6-driving engineer will give you some input....

1) Make phone number a field in your location database.

2) IF the phone number field has a value when a location is selected, then display a CALL tag on the touchscreen.

3) Selecting the CALL option enables your phone (OnStar perhaps?) and outputs the number, then dials the number.

4) If no phone number is associated with the selected location, the CALL option is not displayed on the screen.

5) For your diagram, add a button for CALL linked to the address button enabled only if the field has a 10 digit number in it.

As to your latter question(s), the displayed options on the touchscreen are no different than the buttons on a radio or keyboard - they are switches - the switches are options, they are not the navigation system itself. You want a "switch" that enables your phone.

The only difference from a keyboard and a touchscreen is that a given location ( a displayed "switch") on the touchscreen can be different on every page (screen).

I am sure that some of the young Turks on this forum can clean that up.

Good Luck, gonna go work on my tan.

 

In a Corvette with NAV and OnStar you're already 90% there. The phone interfaces through the NAV/radio for hands' free operation. So it already has audio links to and from the phone. All you need to complete your project is to program the Nav to enable OnStar (requires a momentary contact closure) and send Touchtones[tm] up to the OnStar unit via the existing audio links to do the dialing. Shouldn't be hard to program the Nav to generate TTs, it already has the D/A circuits in it, it just needs a software lookup table to produce the tones. Just a little software.

Adding an external contact closure controlled by the Nav may require a little hardware hacking, but nothing complicated, just an address decoder and an optoisolator off the existing address bus. In other words, just program the unit to write a 1 to an unused address in the unit, and away you go.

Another way to do this with any Nav and any Bluetooth enabled phone is to hack in a Bluetooth interface to the Nav and let it command the phone that way. Again, both a hardware hack and a software change would be required, but this one would be more complicated than the first suggestion because, although the Bluetooth hardware is available in a chipset, the protocol stack to drive it has to reside in the operating software, and it isn't a trivial bit of programming.

 

wow, I am so happy with very quick help and nice people. I am only can say thanks and thanks again. I never expect so fast answers. You have been a great help. sincerely. orlando
