1. A computer-implemented method, comprising:
- acquiring images of an input device with a camera, the input device being on a finger of a user and having a plurality of markers;
identifying segments in the individual acquired images, the identified segments corresponding to the markers;
forming a temporal trajectory of the input device based on the identified segments in the individual acquired images;
correlating the formed temporal trajectory with a computing command; and
executing the computing command by a processor.

Abstract
Embodiments of electronic systems, devices, and associated methods of operation are described herein. In one embodiment, a computing system includes an input module configured to acquire images of an input device from a camera, the input device having a plurality of markers. The computing system also includes a sensing module configured to identify segments in the individual acquired images corresponding to the markers. The computing system further includes a calculation module configured to form a temporal trajectory of the input device based on the identified segments and an analysis module configured to correlate the formed temporal trajectory with a computing command.

12. An electronic system, comprising:
-
a detector configured to detect an input device having a plurality of markers individually configured to emit a signal to form a signal pattern; and a controller operatively coupled to the detector, the controller having a computer-readable storage medium containing instructions for performing a method comprising; receiving input data from the detector, the input data indicating the detected signal pattern from the markers; analyzing the signal pattern to identify at least one of an orientation and position of the input device relative to the detector based on a dimension of the input device and an arrangement of the markers; identifying a computing command based at least in part on at least one of the identified orientation and position of the input device relative to the detector; and executing the computing command with the processor. - View Dependent Claims (13, 14, 15, 16, 17, 18)
