[0022] Although the flowchart 300 of FIG. 3 shows a specific order of execution, it is understood that the order of execution may differ from that which is depicted. For example, the order of execution of two or more blocks may be scrambled relative to the order shown. Also, two or more blocks shown in succession in FIG. 3 may be executed concurrently or with partial concurrence. It is understood that all such variations are within the scope of the present disclosure.

[0023] At block 310, the makeup application device 102 obtains a makeup consultation request from a user of a client device. At block 320, the makeup application device 102 obtains at least one digital image of a facial region of the user from the client device. For some embodiments, this involves causing the client device 122 to prompt the user to face a front facing camera of the client device 122 at a plurality of angles and capturing a digital image at each angle.

[0024] At block 330, the makeup application device 102 generates a 3D facial model based on the at least one digital image. For some embodiments, this involves retrieving a default 3D model and modifying a size and location for predetermined facial features on the default 3D model based on a size and location of corresponding facial features on the at least one digital image of the facial region of the user.

[0025] At block 340, the makeup application device 102 obtains user input from the makeup professional for applying virtual cosmetic effects to the 3D facial model. For some embodiments, obtaining user input from the makeup professional for applying virtual cosmetic effects to the 3D facial model includes obtaining an adjustment to an orientation of the 3D facial model along one or more axes from the makeup professional and displaying the 3D facial model according to the adjusted orientation. For example, the makeup professional may utilize a user interface displayed on the makeup application device 102 to perform rotating and panning operations on the 3D facial model to facilitate application of virtual cosmetic effects. The makeup application device 102 also obtains a location on the 3D facial model and applies a cosmetic effect to the location on the 3D facial model.

[0026] For some embodiments, obtaining user input from the makeup professional for applying virtual cosmetic effects to the 3D facial model includes obtaining a zoom level from the makeup professional and displaying the 3D facial model according to the zoom level. For some embodiments, the makeup application device 102 obtains an enable input from the makeup professional, where the enable input specifies whether to allow the client device to display application of the virtual cosmetic effect at the zoom level. That is, the makeup professional controls whether the user of the client device 122 views application of cosmetic effects according to the zoom level specified by the makeup professional. The makeup application device 102 obtains a location on the 3D facial model and applies a cosmetic effect to the location on the 3D facial model.

[0027] At block 350, the makeup application device 102 generates a command based on the user input from the makeup professional for applying a virtual cosmetic effect. At block 360, the makeup application device 102 transmits the command to the client device, the command causing a virtual cosmetic effect to be applied to the at least one digital image of the facial region of the user and display the at least one digital image. For some embodiments, displaying the at least one digital image comprises displaying a live video feed of the facial region of the user.

[0028] For some embodiments, the makeup application device 102 transmits the command to the client device whenever user input is obtained from the makeup professional, where the command comprises locations of feature points where the virtual cosmetic effects are applied to the 3D facial model. The client device 122 (FIG. 1) maps the feature points where the virtual cosmetic effects are applied to the 3D facial model to feature points on the facial region of the user. The client device 122 then applies the same virtual cosmetic effects to the facial region of the user based on the mapped feature points. For some embodiments, the makeup application device 102 stores a sequence in which the user input is obtained from the makeup professional for applying virtual cosmetic effects to the 3D facial model.

[0029] For some embodiments, the command causes the client device to display application of the virtual cosmetic effect to the at least one digital image of the facial region of the user according to the adjusted orientation obtained from the makeup professional. The command may also cause the client device to display application of the virtual cosmetic effect to the at least one digital image of the facial region of the user at the zoom level obtained from the makeup professional according to the enable input. Thereafter, the process in FIG. 3 ends.

[0030] Having described the basic framework of a system for providing makeup consultation, reference is made to the following figures, which further illustrate various features disclosed above. FIG. 4 illustrates a makeup consultation session utilizing the makeup application device 102 and the client device 122 in FIG. 1 according to various embodiments of the present disclosure. As discussed above, the makeup application device 102 may be embodied as a computing device such as, but not limited to, a smartphone, a tablet computing device, a laptop computer, and so on. As shown, a makeup professional may utilize a pen/stylus in conjunction with a trackpad or tablet coupled to the makeup application device 102 to precisely perform virtual application of cosmetic effects onto a 3D model 402 of the user of the client device 122. The makeup professional may also utilize a touchscreen interface of the makeup application device 102 for performing virtual application of cosmetic effects.

[0031] As discussed above, the makeup application device 102 generates a command based on the actions of the makeup professional for applying a virtual cosmetic effect. In the example shown in FIG. 4, the makeup professional applies a lipstick effect to the 3D model 402. A corresponding command is generated and transmitted via the network 120 to the client device 122. The command causes the client device 122 to display virtual application of a lipstick effect onto a digital image of the user of the client device 122. For some embodiments, the makeup professional can apply a series of cosmetic effects (e.g., lipstick effect, eyeliner effect, blush effect, eyelash effect, eyebrow effect, eyeshadow effect, face foundation effect, hair color effect) and control when a command is generated and transmitted to the client device 122. This may comprise, for example, manipulating a control on a user interface displayed on the on the makeup application device 102.

[0032] FIG. 5 illustrates an example user interface 502 provided on a display of a client device 122 in FIG. 1 according to various embodiments of the present disclosure. Referring back to the example above, a lipstick effect is applied by the makeup professional. This causes a corresponding lipstick effect to be applied to a digital image 504 of the user. In some implementations, a live video feed of the user is displayed on the client device 122 while makeup effects are applied by the makeup professional, thereby providing a virtual mirror effect. For some embodiments, the user of the client device 122 can view the makeup professional applying the makeup effect while simultaneously viewing the makeup effect being applied on the facial region of the user using a picture-in-picture (PIP) layout, a side-by-side layout, and so on. In the example shown in FIG. 5, a PIP window 506 is included in the user interface 502, where the PIP window 506 depicts an image of the makeup professional.

[0033] FIG. 6 illustrates a zooming operation performed on the makeup application device in FIG. 1 according to various embodiments of the present disclosure. In the example shown, the user interface shown on the makeup application device 102 includes a control for allowing the makeup professional to zoom in and facilitate the virtual application of cosmetic effects. For some embodiments, the makeup professional can control whether the user of the client device 122 views the digital image at the zoom level specified by the makeup professional. In the example shown, another control on the user interface viewed by the makeup professional allows the makeup professional to specify whether the display of the client device 122 similarly zooms in to the digital image of the user when the makeup professional zooms in to view the 3D model. In some embodiments, the user of the client device 122 can zoom in and out (independent of the zoom level utilized by the makeup professional on the makeup application device 102) while viewing application of the virtual cosmetic effects by the makeup professional.

[0034] FIG. 7 illustrates adjustment to an orientation of the 3D facial model along one or more axes performed on the makeup application device in FIG. 1 according to various embodiments of the present disclosure. In the example shown, the makeup professional adjusts the orientation of the 3D facial model along one or more axes to facilitate the virtual application of cosmetic effects. For example, the makeup professional may utilize a user interface displayed on the makeup application device 102 to perform rotating and panning operations on the 3D facial model for purposes of applying virtual cosmetic effects. Virtual application of a cosmetic effect on the 3D model causes a corresponding command to be generated and transmitted via the network 120 to the client device 122. The command causes the client device 122 to display virtual application of the same cosmetic effect onto a digital image of the user of the client device 122. The makeup professional may also allow the user to view the current adjusted orientation utilized by the makeup professional while applying the makeup effect.

[0035] FIG. 8 illustrates another example user interface 802 provided on a display of a client device 122 in FIG. 1 according to various embodiments of the present disclosure. In the example shown, a lipstick effect is applied by the makeup professional to a 3D model 806 of the user. The user of the client device 122 views application of the lipstick effect onto the 3D model 306 by the makeup professional in a first viewing window 804. This causes a corresponding lipstick effect to be applied to a digital image of the user. In some implementations, a live video feed of the user is displayed in a second viewing window 808 on the client device 122 while makeup effects are applied by the makeup professional, thereby providing a virtual mirror effect.

[0036] The user interface 802 may also include a third viewing window 810 that shows a live video feed of the makeup professional. Notably, the user is able to simultaneously view images of the makeup professional, the 3D model 806, and the user where application of virtual cosmetic effects is shown in real time to both the 3D model and to the digital image of the user. A similar user interface may be provided to the makeup professional on the makeup application device 102. In other implementations, a picture-in-picture (PIP) configuration may be utilized where the first viewing window 804 encompasses the full display area while the second viewing window 808 and the third viewing window 810 are shown as inset windows on top of the first viewing window 804.

[0037] It should be emphasized that the above-described embodiments of the present disclosure are merely possible examples of implementations set forth for a clear understanding of the principles of the disclosure. Many variations and modifications may be made to the above-described embodiment(s) without departing substantially from the spirit and principles of the disclosure. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims.
