Abstract
An imaging reader is worn by a user. The reader has an imaging assembly that has a solid-state imager with an array of image sensors and a lens assembly. In a reading mode, the imaging assembly captures and projects light as an image onto the array. A controller detects a user's finger pointing at a symbol proximal to a tip of the finger in the image, and generates a control signal when the finger obstructs the symbol in the image. Upon receipt of the control signal, the controller automatically controls a drive to move the imager and/or a lens of the lens assembly to an adjusted position in which the symbol in the image is unobstructed by the finger. The unobstructed image of the symbol is processed into identifying data, and the data is transmitted away from the housing to a remote host device.
