Gesture controllable machine-readable symbol reader systems and methods, with head worn interface

A system that reads machine-readable symbols, comprising:

• at least one wearable image sensor having a field of view, the field of view moveable to selectively encompass respective portions of an environment with movement of the at least image sensor, the at least one image sensor which in operation captures images of the respective portions of the environment within the field of view of the at least one image sensor;
• a control system that is communicatively coupled to the at least one image sensor to receive signals representative of the images, the control system configured to:
• detect an occurrence of a first gesture in the images, the first gesture represented by a trace of a number of movements of a first finger mounted indicia;
• and
• in response to detection of the occurrence of the first gesture, trigger an at least attempt at decoding one or more machine-readable symbols represented in the images,
• wherein the first finger mounted indicia is a first finger mounted non-perceptible digital watermark that is not perceptible by a human, and the at least one of processor-executable instructions or data, when executed by the at least one processor, cause the at least one processor to:
• detect the first finger mounted non-perceptible digital watermark in the images.

• wherein the first finger mounted indicia is at least a first finger mounted light source or at least a first finger mounted retro-reflector, and the at least one of processor-executable instructions or data, when executed by the at least one processor, cause the at least one processor to:
• detect the first finger mounted light source or the first finger mounted retro-reflector in the images.
