Wearable heads-up display with integrated finger-tracking input sensor

A method of providing input to a wearable heads-up display having a wearable frame structure supporting two display elements, where each display element has at least one projection extending away from the display element, each projection configured to secure the heads-up display to a user body element in a manner that, when secured to the user body element, places each display element within a field of view of the user, the method comprising:

• providing, via a processor coupled to the wearable frame structure, display information to at least one display element of the two display elements;
• receiving at the processor, via one of at least two finger-operable substantially-transparent input devices secured to the wearable frame structure and configured to sense at least one of a position and movement of a finger along a planar direction relative to a surface of the input devices, corresponding input information representative of the at least one of the position and movement of the finger along the planar direction, wherein a first finger-operable substantially-transparent input device is secured to the wearable frame structure via a first projection and configured to provide fine-motor input information to the processor, and a second finger-operable substantially-transparent input device secured to the wearable frame structure via a second projection and configured to provide gross-motor input information to the processor;
• and
• providing, via the processor, new display information to the at least one display element responsive to receiving the input information.

An article of manufacture including a computer readable medium having instructions stored thereon that, in response to execution by a computing device of a wearable heads-up display having a wearable frame structure supporting two display elements, where each display element has at least one projection extending away from the display element, each projection configured to secure the heads-up display to a user body element in a manner that, when secured to the user body element, places each display element within a field of view of the user, cause the computing device to perform operations comprising:

• providing display information to at least one display element of the two display elements coupled to the wearable frame structure;
• receiving at the processor, via one of at least two finger-operable substantially-transparent input device secured to the wearable frame structure and configured to sense at least one of a position and movement of a finger along a planar direction relative to a surface of the input device, corresponding input information representative of the at least one of the position and movement of the finger along the planar direction, wherein a first finger-operable substantially-transparent input device is secured to the wearable frame structure via a first of the two projections and configured to provide fine-motor input information to the processor, and a second finger-operable substantially-transparent input device secured to the wearable frame structure via a second of the two projections and configured to provide gross-motor input information to the processor;
• and
• providing new display information to the at least one display element responsive to receiving the input information.
