Finger Control Patent For Google Glass
Google is apparently considering a control mechanism to be either embedded into wearable units or attached to a fingernail and to interact with a head-mounted display. The United States Patent 8,179,604 (filed in September) states: “In accordance with example embodiments, a wearable marker may be used for passive interaction with a wearable computing device. A wearable marker may take the form of a ring, a bracelet, an artificial fingernail configured to be affixed to a fingernail, a decal configured to be affixed to a fingernail, or a glove, among other possible wearable items. A wearable marker may further include an infrared (IR) reflective surface in the form of a surface pattern that is substantially optically invisible. A wearable computing device may include a head-mounted display (HMD) equipped with an IR camera device capable of detecting IR radiation reflected from the surface pattern on a wearable marker. The HMD and the IR camera device can function together to track position and motion of the wearable marker via reflection, and by doing so can recognize known patterns of motion that correspond to known hand gestures.” Sounds like the Project Glass will have their AR glasses controlled with fingers.
