(1) regarding claim 30:
As shown in fig. 1, Sztuk disclosed a smart glasses apparatus (para. [0025], note that FIG. 1 illustrates an example head mounted device 100 for capturing gaze-guided images), comprising:
a physical frame (102, frame fig. 1, para. [0025]);
an outward-facing camera assembly configured to capture images (193A, outward facing camera, fig. 1, para. [0034], note that camera 193A is configured to image the external environment to the right of head mounted device 100 and camera 193D is configured to image the external environment to the left of head mounted device 100);

[0075], note that a tangible or non-transitory machine (e.g., computer) readable storage medium, that when executed by a machine will cause the machine to perform the operations describe), cause the smart glasses apparatus to:
capture an image via the outward-facing camera assembly (para. [0036], note that in FIG. 2A, first camera 293A includes a first image sensor configured to capture first images 295A of an external environment of a head mounted device);

Images captured by the sensor(s) 125 may be processed to detect and track gaze direction and movement, and to detect gaze fixation).
At the time of filing for the invention, it would have been obvious to a person of ordinary skilled in the art to teach determine a location in a 3D space based on the image and the gaze vector. The suggestion/motivation for doing so would have been in order to interact with content made available by wearable computing devices, capture and/or process and/or access information using wearable computing devices, and rely on wearable devices to interact with content made available by the wearable device (para. [0002]). Therefore, it would have been obvious to combine Sztuk with Spencer to obtain the invention as specified in claim 30.

Sztuk disclosed most of the subject matter as described as above except for specifically teaching where the instructions further cause the smart glasses apparatus to measure the distance to a golf stick.
However, Geisen disclosed where the instructions further cause the smart glasses apparatus to measure the distance to a golf stick (fig. 3, page 4, note that XR training from the perspective of HoloLens 2 glasses. The virtual golf club (model) provided the spatially and temporally optimized club motion when putting from a distance of 3 m).
At the time of filing for the invention, it would have been obvious to a person of ordinary skilled in the art to teach where the instructions further cause the smart glasses apparatus to measure the distance to a golf stick. The suggestion/motivation for doing so would have been in order to interact and provide feedback which could enhance motor learning in sports (abs.).

In other implementations, other techniques or angular representations for measuring head pose can be used, for example, quaternion angles, note that the head pose sensor comprises an inertial measurement unit (IMU), an accelerometer, a gyroscope, or a magnetometer, para.

However, Spencer disclosed the smart glasses apparatus to determine an other location in the fixed frame of reference based on the image and an other gaze vector, and estimate a distance or a size based on the location and the other location (para. [0039], note that known position of the eye of the user by the gaze tracking device(s) 120 and a transform from the field of view of the gaze tracking device 120 to the field of view of the camera 116 allows the angle and the distance from the camera 116 to the eye of the user to be computed, yielding one side and two angles of a triangle formed by the camera 116, the eye of the user, and the object of interest. Casting rays along these two angles to their intersection may provide an estimate of distance).
At the time of filing for the invention, it would have been obvious to a person of ordinary skilled in the art to teach the smart glasses apparatus to determine an other location in the fixed frame of reference based on the image and an other gaze vector, and estimate a distance or a size based on the location and the other location. The suggestion/motivation for doing so would have been in order to interact with content made available by wearable computing devices, capture and/or process and/or access information using wearable computing devices, and rely on wearable devices to interact with content made available by the wearable device (para.
