    CarPC auto-login

    I know it is possible to set up Windows XP to auto-login as the default user. My question (and current project till I have enough money saved up for the carpc itself) is how to make the carpc auto-login with a different user based upon who is driving the car?

    From what I have found so far in Windows auto-login feature, it uses registry keys to determine who is the default user. If a service was running, it could detect login info from some device (say a USB thumbdrive) and place that information in the registry keys required.

    The final product should get the info off of a keychain with one of those swipe card style things inside. The senor to read the keychain could be mounted in the steering column.

    This isn't the same, but seems related. It seems that you woudl want something like this, but with multiple transmitters that were assigned to different users.

    Yeah dude... those biometric fingerprint readers come with software that allows different users to login simply by swiping their thumb across the reader. They are fairly cheap too (not any more expensive the a card-strip reader anyway)

    Two meters is a little to big of a distance for what im looking for. I was thinking more like 2 or 3 inches. What if the 2 users of the car (say a husband and wife) are both riding in the car. The computer wouldn't know which one to log in. But if the sensor was in the steering column, the transmitter was on the keychain with the car key, and the distance was only a couple inches then it would only log in the driver. The passenger would still have the option of clicking the switch user option in the start menu to change to thier profile if need be.

    As for the fingerprint readers, those could work but I hope to get it to a point where the user only has to have a keychain on his keys to log in and does not have to do anything special other then start the car.

    As for the card swiping technology I was refering to, I didn't mean the card strips like on a credit card. I was refering to the little magnetic (I think it is) deal in the solid plastic cards they use to open doors and the likes. Another example for those that have seen them are those Mobil Gas Station speed pass things. You wave the little keychain wand over a sensor in the pump and it charges your credit card automatically.

    I think what you're talking about is RFID. I don't know of any products like you described, though.

    Why would you want different desktops for different drivers in a car anyway? You might want a music player to load different playlists or something, but the Windows desktop and the core CarPC apps should always be the same.

    I am also planning on using a different shell then the standard explorer.exe. With the hack I have on my desktop, I can allow different users to use different shells. So each user can have thier own skin for the shell with shortcuts to the apps they use more often. Say the husband is a car guy and want to see the OBD-II stuff alot but the wife isn't and doesn't care about it at all. The husband's skin would have a button for the OBD-II but the wife's doesn't. Of course these apps would still be accessable, just not have a shortcut to them.
    Plus different drivers also listen to music at different volume levels. The service that auto-logins can also set the volume level to the desired one.

    All sorts of user have all sorts of different preferences. I have seen this over the several, several years I have been dealing with computers. The easiest way of dealing with these different preferences is different user profiles. Also a lack of this login info would cause it to default to a guest account and maybe (as per the other thread) run security software.
