DETAILED DESCRIPTION
This disclosure outlines a system consisting of a mobile, tablet, or other computer system with a touch or mouse input, where a user rotationally navigates through a set of cascaded radial menus to narrow down upon a final selection for modifying a digital image rendered on the computer system.
The system consists of a mobile, tablet, or other computer system with a touch or mouse input, where the described user interface is going to be implemented on.
The input from the user is delivered to the system based on the finger-touch hardware. The system will then process the user's input in order to proceed with the rest of the procedure and make further decisions as will be described.
The user starts by choosing a photo to modify. This photo could come from any available source, including (but not limited to) the local photo library on the mobile device, the camera available on the device, a remote server, etc.
After selecting the digital image to modify, the image will be processed and analyzed by the system and then a variety of image modification effects will be provided to the user to select from, where each of these effects is associated with a certain type of product in the real-world.
In one embodiment, the image is an image of a face, where all facial features, for example, eyes, lips, nose, eyebrows, etc. are visible, and the image also contains a large enough region around the persons face (so a fair amount of the person's hair is also seen in the image). The products are also beauty products that could be applied to the face, such as eye products (eyeliner, eye shadow, etc.), lip products(lipstick, lip gloss, etc.) and skin products (foundation, etc.).
In one embodiment, the user interface for the virtual makeover mobile application has many unique elements. This application was specially designed to make the user interaction as seamless as possible making the most ideal makeover experience.
Thumb Wheel
This thumb wheel may be the main category selection menu. It may be positioned in the bottom corner of the screen. A mobile device is held in someone's hand which enforces their thumbs to be the drivers of the screen. Strategically placing the menu thumb wheel—which is the portion of the application most interacted with ̃close to the bottom corner makes the use of the app significantly easier than having it placed anywhere else on the screen. This wheel is switched from the right side to the left side based on user information if they are right-handed or left-handed,
In one embodiment, the categories available on the thumb wheel are the main beauty and makeup categories, such as eyes, lips, face, etc. Once the user selects any of these main categories, the system will proceed to subcategories using the cascading category rings, where the user can narrow down the choice of the beauty products.
Cascading Category Rings
The category thumb wheel has successive rings that open to display sub-category menus for users to further interact with the application. These rings have a cascading effect so the recent-most opened menu is displayed at the outer layer of the rings with the largest radius, and the previous menus are absorbed in the inner ring layers with smaller radius. Thus, the user will always have the option to go backwards and change previously made selections.
FIG. 1 shows in one embodiment, a category menu ring having cosmetics makeup category menu options for applying the image modification.
Each ring is representative of all possible options available for a certain category of image modification effects. So the user can scroll through a certain category of image modification effects at once by simply swiping the corresponding ring.
Once the user selects a category, he will be directed to the next sub-category, and the same scrolling and choosing process will keep going, until the required image modification effect has exactly been selected among all different types and categories of effects.
FIG. 2 shows in one embodiment, successive sub-category menu ring having options corresponding to different lip-related beauty products where previously presented categories are merged into a back button.
Product Element Arch
FIG. 3 shows in one embodiment, presenting the possible color options for a certain image modification effect where previously presented categories are merged into a back button.
FIG. 4 shows use of the product effect options arch to present all possible element options for a selected image modification effect to the user, where the arch can be scrolled in order to search the options.
The product arch can easily be scrolled through using your thumb to search for the desired color to be applied. The product selection is also an additional category wheel in the cascading menu, for certain devices. This allows for optimum use for the user. In a sweep of their thumb a user can select a category (i.e. Lips) then select a sub category (i.e. lip gloss) then scroll through a variety of shade, select their preferred color and have it automatically applied to their image. This is the most seamless interface that makes the makeover experience quick and painless.
An example of the rotational cascaded menu workflow is shown in FIGS. 5-6. In this embodiment, the image modification effects are related to the simulation of beauty and makeup products on a digital photo of a person's face. The main categories in this example include modification of different facial features, including (but not limited to) face, lips, and eyes.
FIG. 5 shows in one embodiment, the rotational cascaded menu used to select the face modification category, then selecting the foundation sub-category, and finally choosing the desired foundation color using the product effect options arch, to apply the image modification effect. In FIG. 5, the user has selected the subcategory “Foundation” from the main category “face”. Then, the element arch is presented to the user so he/she can scroll through a variety of different color elements, and choose the desired color for foundation. The final image on the right of FIG. 5 displays the modified image based on the user's selection of the modification categories and their details, which is the digital image of the person's face where the foundation color has been modified here.
FIG. 6 shows in one embodiment, use of the rotational cascading menu to select the lips modification category, then select the lip gloss sub-category using the thumb wheel, and finally chose the desired gloss color using the product effect options arch, to apply the image modification. In FIG. 6, the user has selected the subcategory “lip gloss” from the main category “lips”. Then, the element arch is presented to the user so he/she can scroll through a variety of different color elements, and choose the desired color for the lip gloss. The final image on the right of FIG. 5 displays the modified image based on the user's selection of the modification categories and their details, which is the digital image of the person's lips where the gloss color has been modified here.
FIG. 7 shows in one embodiment, use of the product options arch to present the options for eye coloring, and applying the desired eye coloring effect based on the user's selection of options presented via the arch. In the embodiment presented in FIG. 7, the image modification effect is changing the color and texture of a person's eye in a digital image, to a desired eye color and texture, selected by the user. The image on the left in FIG. 7 displays the digital image with the element arch presenting a variety of different eye color and texture effects to the user. The user can scroll through the elements and chose the desired one The image on the right in FIG. 7 displays the modified digital image based on the user's selection of the modification details and elements, i.e. the digital image in which the color and texture of the person's eyes has been transformed to the target eye color and texture selected by the user.
FIG. 8 shows in one embodiment, application of the product options arch to present the options for nail salon coloring, and application of the desired nail salon color effect based on selection of product effect options. In the embodiment presented in FIG. 8, the image modification effect is modifying a digital image of a person's hand, in order to simulate the effect of a nail salon, selected by the user. The image on the left in FIG. 8 displays the digital image with the element arch presenting a variety of different nail salon effects to the user. The user can scroll through the elements and chose the desired one. The image on the right in FIG. 8 displays the modified digital image based on the user's selection of the modification details and elements, i.e. the digital image in which the effect of applying the nail salon chosen by the user has been simulated.
FIG. 9 shows a flowchart of a process, in one embodiment, for modifying a digital image based on rotational cascaded menus. A digitally rendered initial semicircular menu may be centered at one of the corners of the display which consists of an initial set of options displayed in the menu. Provided is the ability to rotate the menu to reveal additional options, the ability to select one of the options in the menu by touching, clicking, or other means, and one or more additional digitally rendered semicircular menus with increasing radial ring sizes that are only displayed once a selection is made in the initial menu, or once a selection is made in any subsequent menus prior to a current menu. Once a selection is made in the final semicircular menu, to activate a specific photo effect which is applied to the original image. The initial menu ring may consists of a primary cosmetics category, the secondary menu consists of a cosmetics subcategory, and the third and final menu ring consists of color swatches associated with the chosen subcategory. IN an embodiment, only the current menu is shown as a semicircular ring and all previous menus are hidden. Yet further, the hidden previous menus may be accessed by a single back button centered in the semicircular menu touching or clicking which sequentially goes back to the previous menu level.
Although the invention has been described with reference to specific exemplary embodiments in the field of cosmetics products and visually simulated usage thereof, it pertains to other kinds of products amendable to simulated usage based on a digital image.
