Finally, the system may pair the input device with the selected display device and a communication mode may be selected whereby the input device can communicate with the vehicle infotainment system.
1. A method for utilizing an input device in conjunction with a vehicle infotainment system, comprising:
detecting, by the vehicle infotainment system, presence of the input device;
in response to detecting the presence of the input device, selecting, based on an identity of a user associated with the input device or a detected location associated with the input device, a display device from a plurality of display devices of the vehicle infotainment system;
pairing the input device with the selected display device of the vehicle infotainment system;
determining whether an identifier of a plurality of identifiers is associated with the input device:
selecting, based on a rule, at least one mode of a plurality of modes associated with the identifier;
setting the selected mode as the communication mode whereby the input device communicates with the vehicle infotainment system; and
directing input events received from the input device via the communication mode to one or more processes executing in the infotainment system corresponding to the selected display device.
2. The method of claim 1 , wherein each mode of the at least one mode is associated with a weighing factor; and
the selecting the mode of the at least one mode associated with the identifier is based on the weighing factor of each mode of the at least one mode.
3. The method of claim 2 wherein the weighing factor for each mode of the at least one mode is determined based on a number of times or an amount of time that each mode of the at least one mode has been used to communicate with the input device.
4. The method of claim 1 , wherein the selecting of the display device is based on the identity of the user associated with the input device, and the selecting comprises:
recognizing the user associated with the input device as a registered user of the vehicle infotainment system;
determining a seat location of the registered user of the vehicle infotainment system; and
selecting the display device based on the determined seat location of the registered user.
5. The method of claim 4 , wherein the seat location of the registered user is determined based on a last known location from where the registered user performed a login to the vehicle infotainment system.
6. The method of claim 4 , wherein the seat location of the registered user is determined based on a location where the registered user is detected based on biometric information.
7. The method of claim 1 , wherein the selecting of the display device is based on the detected location associated with the input device, and the selecting comprises:
determining a location of a port of the vehicle infotainment system making a wired connection with the input device; and selecting the display device based on physical proximity of the display device to the determined location of the port.
8. The method of claim 1 , wherein the selecting of the display device is based on the detected location associated with the input device, and the selecting comprises:
estimating the location of the input device based on wireless ranging signals;
selecting the display device based on the estimated location of the input device.
9. The method of claim 1 , wherein the detecting of the presence of the input device comprises detecting a wired or wireless connection made between the input device and a port of the vehicle infotainment system.
10. The method of claim 9 , wherein the wired or wireless connection is a USB connection.
11. The method of claim 9 , wherein the wired or wireless connection is a Bluetooth connection.
12. The method of claim 1 , wherein the detecting of the presence of the input device comprises detecting a device ID associated with the input device.
13. The method of claim 1 , wherein the input device is a smart phone.
14. A vehicle infotainment system comprising:
a plurality of display devices;
a transceiver unit configured to communicate with the plurality of display devices and a first input device via any one of a plurality of modes;
a processing unit communicatively coupled to the transceiver unit and configured to:
detect the presence of the first input device;
detect whether the first input device communicates with the transceiver unit via a first mode of the plurality of modes;
determine whether a second mode of the plurality of modes is supported by the first input device, including determining whether the first input device has previously been communicated with the vehicle infotainment system via the second mode;
determine, based on a determination by the vehicle infotainment system that the second mode is preferred over the first mode, whether to select the second mode for communication with the first input device; and
send a message, via the transceiver unit, to the first input device identifying the second mode;
selecting, based on an identity of a user associated with the first input device, a display device from the plurality of display devices of the vehicle infotainment system;
pairing the first input device with the selected display device, wherein as a result of the pairing, input events received from the first input device are directed, via the second mode, to one or more processes corresponding to the selected display device.
15. The vehicle infotainment system of claim 14 , wherein the selecting of the display device is based on the identity of a user associated with the first input device, and the selecting comprises:
recognizing the user associated with the first input device as a registered user of the vehicle infotainment system;
determining a seat location of the registered user of the vehicle infotainment system; and
selecting the display device based on the determined seat location of the registered user.
16. The vehicle infotainment system of claim 15 wherein the first input device is a smart phone.
17. A system for utilizing an input device in conjunction with a vehicle infotainment system, comprising:
means for detecting, by the vehicle infotainment system, presence of the input device;
means for, in response to detecting the presence of the input device, selecting, based on an identity of a user associated with the input device or a detected location associated with the input device, a display device from a plurality of display devices of the vehicle infotainment system;
means for determining whether an identifier of a plurality of identifiers is associated with the input device;
means for selecting, based on a rule, at least one mode of a plurality of modes associated with the identifier;
means for setting the selected mode as the communication mode whereby the input device communicates with the vehicle infotainment system; and
means for pairing the input device with the selected display device of the vehicle infotainment system, wherein as result of the pairing, input events received from the input device are directed by the vehicle infotainment system to one or more processes executing in the infotainment system corresponding to the selected display device.
