Abstract
Systems and methods for capturing machine-readable symbols using a finger mounted indicia. The system includes an image sensor that captures a plurality of images from the field of view of the image sensor. An occurrence of a gesture is detected in the plurality of images, in which the gesture is represented by a trace of a number of movements of a finger mounted indicia. In response to detecting the occurrence of the gesture, an at least attempt is triggered to decode one or more machine-readable symbols represented in the images. The gesture may be used to indicate a region of interest that includes the machine-readable symbol. Such indication may improve the efficiency and processing time needed to detect and decode a machine-readable symbol.
