Abstract: A system and method of detecting scale from image data obtained by a computing device together with position and orientation of the computing device is provided. The scale may be used for the virtual selection and/or fitting of a wearable device such as a head mounted wearable device and other such wearable devices. The system and method may include capturing a series of frames of image data, and detecting one or more fixed features in the series of frames of image data. Position and orientation data associated with the capture of the image data is combined with the position data related to the one or more fixed features to set a scale that is applicable to the image data. Scale may be determined without the use of a reference object having known scale, specialized equipment, and the like.

Abstract: Systems and methods for validation of modeling and simulation systems that provide for the virtual fitting of wearable devices, such as glasses, by a user. Three-dimensional modeling and simulation of test subject both with and without fitting frames corresponding to a wearable device may be captured to validate the modeling and simulation modules and associated algorithms and machine learning modules used to simulate the fit of the wearable device on a user. Validation in this manner may provide for increased accuracy/realism of the modeling and simulation systems.

Abstract: A system and method of detecting display fit measurements and/or ophthalmic measurements for a head mounted wearable computing device including a display device is provided. An image of a fitting frame worn by a user of the computing device is captured by the user, through an application running on the computing device. One or more keypoints and/or features and/or landmarks are detected in the image including the fitting frame. A three-dimensional pose of the fitting frame is determined based on the detected keypoints and/or features and/or landmarks, and configuration information associated with the fitting frame. The display device of the head mounted wearable computing device can then be configured based on the three-dimensional pose of the fitting frame as captured in the image.

Abstract: A system and method are provided for sizing and fitting a head mounted wearable computing device for a user based on image data of the head of the user, including a known reference device having a known scale. The system and method may include capturing image data including a face of the user to be fitted for the head mounted wearable computing device. The known reference device having the known scale is compared to features detected in the image data to determine a scaling factor. The scaling factor is used to size, or assign measures to facial features detected in the image data. A three-dimensional model of the head of the user may be generated from the captured image data.

Abstract: According to an aspect, a method for designing an eye tracker on a wearable device includes selecting a first three-dimensional (3D) model of at least a head of a person, selecting a second 3D model of a wearable device, positioning a synthetic eye within the first 3D model, positioning an eye tracker component at a first location on the second 3D model, the eye tracker component including at least one of an eye tracker sensor or a light source, moving at least one of the first 3D model or the second 3D model such that at least a portion of the first 3D model contacts at least a portion of the second 3D model, and generating performance data with the eye tracker component positioned at the first location on the second 3D model.

Abstract: A system and method of detecting display fit measurements and/or ophthalmic measurements for a head mounted wearable computing device including a display device is provided. An image of a fitting frame worn by a user of the computing device is captured by the user, through an application running on the computing device. One or more visual markers each including a distinct pattern are detected in the image including the fitting frame. A model of the fitting frame, and configuration information associated with the fitting frame, are determined based on the detection of the pattern. A three-dimensional pose of the fitting frame is determined based on the detected visual marker(s) and patterns, and the configuration information associated with the fitting frame. The display device of the head mounted wearable computing device can then be configured based on the three-dimensional pose of the fitting frame as captured in the image.
