System and methods for providing orientation compensation in pointing devices
Axis orientation compensation is provided in a system in which movement of a controlling device is used to control navigational functions of a target appliance by determining which one of plural sides of the controlling device is an active side of the controlling device and by causing navigational functions of the target appliance made relative to at least one of an X, Y, and Z axis of the target appliance to be dynamically aligned with movements of the controlling device made relative to at least one of an A, B, and C axis of the controlling device as a function of the one of the plural sides of the controlling device that is determined to be the active side of the controlling device.
1. A method for providing axis orientation compensation in a system in which movement of a controlling device is used to control navigational functions of a target appliance, comprising:
receiving by the target appliance from the controlling device a navigational command wherein the navigational command comprises data indicative of a one of a plurality of sides of the controlling device that was determined by the controlling device to be an active side of the controlling device and data indicative of a movement of the controlling device along a one of an A, B, or C axis of the controlling device;
using the data in the received navigational command by the target appliance to determine whether the target appliance is to respond to the received navigational command by performing a navigational function in a one of an X, Y, or Z axis of the target appliance; and
performing by the target appliance the navigational function in the determined one of the X, Y, or Z axis of the target appliance.
2. The method as recited in claim 1 , wherein the controlling device comprises at least one orientation sensor and the method comprises using a signal generated by the at least one orientation sensor to determine which one of the plurality of sides of the controlling device is the active side of the controlling device.
3. The method as recited in claim 2 , wherein the at least one orientation sensor comprises an accelerometer.
4. The method as recited in claim 3 , comprising using the signal generated by the at least one orientation sensor to also track movements of the controlling device made relative to the A, B, or C axes of the controlling device.
5. A method for providing axis orientation compensation in a system in which movement of a controlling device is used to control navigational functions of a target appliance, comprising:
in response to a movement of the controlling device along a one of an A, B, or C axis of the controlling device, transmitting from the controlling device to the target appliance a navigational command to cause the target appliance to perform a navigational function in a one of an X, Y, or Z axis of the target appliance wherein the controlling device determines whether the target appliance is to perform the navigational function in the one of the X, Y, or Z axis of the target appliance as a function of which one of a plurality of sides of the controlling device was determined by the controlling device to be an active side of the controlling device and the one of the A, B, or C axis of the controlling device along which the controlling device was moved to cause the navigational signal to be sent to the target appliance.
6. The method as recited in claim 5 , wherein the controlling device comprises at least one orientation sensor and the method comprises using a signal generated by the at least one orientation sensor to determine which one of the plurality of sides of the controlling device is the active side of the controlling device.
7. The method as recited in claim 6 , wherein the at least one orientation sensor comprises an accelerometer.
8. The method as recited in claim 6 , comprising using the signal generated by the at least one orientation sensor to track movements of the controlling device made relative to the A, B, or C axes of the controlling device.
