Abstract
Embodiments of a sensor array are disclosed.
Claims20
A registration system comprising:
- first means for displaying first information, input with an input device, and for including at least first and second tank circuits in a predefined configuration;
- and
- second means for determining a first arbitrary orientation of the first means relative to a sensor array using the first and the second tank circuits in response to the first means being placed on the sensor array.
A method comprising:
- sending a first plurality of signals from a sensor array with a plurality of sensors;
- and
- determining a first orientation of a display surface by identifying first and second ones of the plurality of sensors that receive first and second signals, respectively, in response to the first plurality of signals and by using first information that identifies a configuration of at least first and second tank circuits of the display surface.
A system comprising:
- a sensor array configured to detect first information input to a display surface including at least first and second tank circuits using an input device and configured to detect first and second positions of the first and the second tank circuits, respectively, relative to the sensor array in response to the display surface being placed on the sensor array.
