Augmented reality for enhancing sporting events

A method in a plurality of client mobile computing devices for providing augmentations to a live sporting event being performed on a stadium field, the augmentations for each of the respective plurality of client mobile computing devices generated and calibrated based upon the respective client device, comprising:

• for each respective client mobile computing device, executing an augmented reality application configured for:
• receiving an indication of a seat location from which the client mobile computing device is viewing the stadium field;
• calibrating the application in real time to a three dimensional position of the respective computing device based upon the received seat location and to an orientation of the respective computing device and aligning a camera of the computing device to render augmentations in a correct aspect onto a virtual event field corresponding to the stadium field;
• and
• presenting augmentations in real time onto the virtual event field on a display of the respective client mobile computing device as a user is viewing the event live on the stadium field, the augmentations being configured specific to the respective computing device based upon one or more chroma keys uniquely associated with the respective computing device, the one or more chroma keys based upon the determined device position and orientation and configured to be dynamically modified during event play.

A computer-readable memory medium comprising instructions the comprise an augmented reality application configured to control a computer processor in a mobile client comprising device to perform a method comprising:

• receiving an indication of a seat location from which the client mobile computing device is viewing the stadium field;
• calibrating the application in real time to a three dimensional position of the mobile client computing device based upon the received seat location and to an orientation of the computing device and based upon a computed alignment of a camera of the computing device to render augmentations in a correct aspect onto a virtual event field corresponding to the stadium field;
• sensing an actual position of the mobile client computing device;
• comparing the sensed position to the calibrated application to adjust for error in expected orientation and position;
• and
• presenting augmentations in real time onto the virtual event field on a display of the client mobile computing device as a user is viewing the event live on the stadium field adjusting for the error in expected orientation and position, the augmentations being configured unique to the computing device based upon one or more chroma keys associated with the computing device, the one or more chroma keys based upon the determined device position and orientation and configured to be dynamically modified during event play.
