Wearable marker for passive interaction
First Claim
1. A computer-implemented method comprising:
- at a wearable head-mounted display (HMD), detecting infrared (IR) radiation reflected from an IR reflective surface on a hand-wearable item, the IR reflective surface being in the form of a particular surface pattern and being substantially optically invisible;
decoding the particular surface pattern from the detected IR radiation to obtain an item identifier;
determining that the item identifier matches a predetermined identifier associated with the wearable HMD; and
responsive to determining that the item identifier matches the predetermined identifier, tracking position and motion of the hand-wearable item relative to the wearable HMD by measuring position and motion of the particular surface pattern relative to the wearable HMD via the detected IR radiation.

Abstract
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.
