Abstract: An ear saddle point of a subject's ear is determined to produce specifications to fit a wearable apparatus to a subject's head. A boundary of the subject's ear in a profile image is determined using a first model. A map of the subject's ear is generated indicating probable locations of a two-dimensional ear saddle point. A most probable location of the two-dimensional ear saddle point is determined based on the probability map. The two-dimensional ear saddle point is projected onto a three-dimensional mesh surface representing the subject's head. A maximum depth of the three-dimensional mesh surface is determined in a defined region around the projected two-dimensional ear saddle point. The ear saddle point is computed based on the projected two-dimensional ear saddle point and the determined maximum depth. Specifications of a wearable apparatus are generated to fit the apparatus to the subject's head based on the computed ear saddle point.

Abstract: Techniques and systems associate augmented tag data with content data and provide for output of content associated with the content data. An augmented tag data is generated by associating anchor tag data with secondary tag data, the anchor tag data and the secondary tag data being associated with an image. Content data is associated with the augmented tag data and the augmented tag data is output in association with the content data. In another approach, a wearable heads up display (WHUD) or other system captures a live view (LV) image in a line of sight of a user of the WHUD, a match is detected between the augmented tag data and a combination of anchor tag data and secondary tag data associated with the LV image, and the content associated the content data is output via the WHUD.
