A mobile computing device comprises an AR display, an image capture device that generates image data of a face of a viewer of the AR display, and a processing device. The processing device receives the image data; processes the image data to identify a position of a dental arch in the image data; determines a treatment outcome for the dental arch; generates a post-treatment image of the dental arch that shows the treatment outcome; generates updated image data comprising a superimposition of the post-treatment image of the dental arch over the received image data depicting the face of the viewer; and outputs the updated image data to the AR display, wherein the post-treatment image of the dental arch is superimposed over the dental arch in the received image data such that the post-treatment image is visible in the AR display rather than a true depiction of the dental arch.

There is provided an imaging lens and an imaging device with a wide angle of view capable of forming an image of an object near an optical axis with a high resolution while having a small size as a whole. The imaging lens is an imaging lens including a first lens G1 having a convex surface on an object side and having a negative refractive power, a second lens G2 having a concave surface on an object side, a third lens G3, a fourth lens G4, a fifth lens G5, and a sixth lens G6, which are sequentially arranged from the object side, and satisfies a predetermined condition. Further, an imaging device according to the present invention includes the imaging lens.

A computing system is provided. The computing system includes a head mounted display (HMD) device including a display, a processor configured to execute one or more programs, and associated memory. The processor is configured to display a virtual object at least partially within a field of view of a user on the display, identify a plurality of control points associated with the virtual object, and determine that one or more of the control points associated with the virtual object are further than a predetermined threshold distance from the user. The processor is configured to, based on the determination, invoke a far interaction mode for the virtual object and receive a trigger input from the user. In response to the trigger input in the far interaction mode, the processor is configured to invoke a near interaction mode and display a virtual interaction object within the predetermined threshold distance from the user.

A wearable computing system that includes a head-mounted display implements a gaze timer feature for enabling the user to temporarily extend the functionality of a handheld controller or other user input device. In one embodiment, when the user gazes at, or in the vicinity of, a handheld controller for a predetermined period of time, the functionality of one or more input elements (e.g., buttons) of the handheld controller is temporarily modified. For example, the function associated with a particular controller button may be modified to enable the user to open a particular menu using the button. The gaze timer feature may, for example, be used to augment the functionality of a handheld controller or other user input device during mixed reality and/or augmented reality sessions.

Methods and apparatuses related to fiducial designs for fiducial markers on glass substrates, or other transparent or translucent substrates, are disclosed. Example fiducial designs can facilitate visual recognition by enhancing edge detection in visual perception. In example fiducial designs, optical features on glass substrates can re-direct light so as to present a bright image region. Such optical features can include surface relief patterns formed in a coating on the surface of glass substrates. An exemplary method for manufacturing the fiducial markers can involve transfers of a fiducial design across a master mold or plate, a submaster mold or plate, and a target glass substrate. A fiducial marker can facilitate the use of the substrate in a variety of applications, including machine vision systems that facilitate automated performance of manufacturing processes on input working material.
