Abstract

A system and method uses an electronic device with a camera and a viewing device to create an augmented reality environment by superimposing a virtual image onto a surface for a user to trace with a drawing apparatus. The system and method can be used to directly copy a virtual image onto a surface by hand and provides training, step by step drawing tools, and image verification. By looking through a user's device and following step by step lessons, the user is guided to complete an image.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS

(15) The apparatus, which includes a camera, processing unit, and display, virtually superimposes an image over a real surface for a surface for a user to reference or trace. According to one aspect of the invention, the apparatus is a cellular phone, tablet, or the like. The method of teaching to drawing uses any device such as a mobile phone, tablet, or the like that has a camera and a screen using augmented reality. By looking through the device and following step-by-step lessons a user is guided to completing an image.

(16) There are various modes of user experiences. All of the modes have settings that include: camera, strobe, grid and light features that can be modified by the user.

(17) The camera setting, allows the user to pause the camera so they can easily compare what is on the screen with the image they are attempting to draw. This setting is used in situations where an artist trying to learn to draw by attempting to draw a picture freehand without the aid of the app. The artist then uses the app to see what areas are not accurate. Other camera setting adjust the focus of the camera to fit the user's preferences.

(18) Using the strobe setting, the display of the device switches or strobes between the picture being drawn (the work) and the original picture that is being duplicated. Using the strobe setting, the user can compare the two pictures to determine is anything is missing from the duplicated drawing.

(19) Using the grid, a grid is overlaid on the image to be drawn. The image can then be drawn in an enlarged or reduced manner using the grid. The grid is drawn in by the application and laid over the image and the camera at the same time. This method allows a user to use the popular method of drawing with a grid without having to put lines down on the paper. Using the grid also allows the user to more easily scale images up or down. The drawing is reproduced in a step-by-step manner, as the drawing is reproduced and the paper is stepped.

(20) In a classic mode an image is uploaded from the device. The image can be stored on the device, retrieved from an online storage location, or the like. The application acts as a virtual tracing tool and has various levels of transparency that the user is able to modulate. By following along with the levels of gradient the user is able to create their picture.

(21) An image to be drawn is overlaid on a real piece of paper using a device's camera. While looking through the device, while it is above the canvas, it creates a virtual projection that can be traced. This enables a user to create realistic looking artwork with perfect proportions, shading, and colors. The application allows a user to zoom in on both the camera and the overlay image at the same to pick up micro details in a drawing or scale the drawing to any desired size.

(22) In the Step by Step Mode an image is broken down into layers by either color or value (levels of darkness) so the user can trace each layer individually in steps. The layers enable the user to draw or paint a picture in steps.

(23) FIGS. 2-6 are examples of the step-by-step mode. In the step by step mode an image is first uploaded to be displayed on the device. The original image is shown with different opacities in FIGS. 12A and 12B. The device renders the image into layers, which vary by shade or color. A slider or other selection tool is used to display each of the layers to be drawn. The different layers correspond to colors or grey scale values according to a generated chart. The grey scale cam be seen beneath the image being drawn

(24) FIGS. 7-10 are sample images in a step-by-step lesson. As shown in FIG. 7, a pen and piece of paper are visible behind an anime girl that will be drawn. The pen is visible to demonstrate the transparency of the image to be drawn. The image is not projected onto the paper. The image is shown on the display of the device overlaid on the image of the paper where the user will draw the image.

(25) Initially, an image to be drawn is selected. In this case, the image selected is an anime girl. Categories from which an image can be selected are shown in FIG. 11. Once the image is selected, the device is placed on a stand so that a user is able to view what will be drawn beneath the device, and the user decides on placement of the image on the page. The stand can be anything that lifts the device from the surface of the page. Once a location for the drawing is selected, the drawing begins. In this example, the first step is to begin drawing the anime girl's eye, as shown in FIG. 8. The lesson continues using a transparent line-by-line lesson as shown in FIG. 9. The finished outline of the anime girl is shown in FIG. 10.

(26) The lessons mode uses augmented reality in which the user is able to follow along with a tutorial by tracing an image such as the anime girl in a step-by-step manner. The lessons mode is used to teach the user to draw using proportions. During the lessons mode users learn the fundamentals of drawing so that the user will eventually be able to draw without the application. Lessons include lines, shapes, figures, shading, perspective, and the like. The application allows a user to trace pictures or as a tool to periodically check proportions as the user draws free hand. This insures that while drawing a portrait the elements are each in their proper place. Users can lay everything out in a drawing prior to beginning to draw and then check the drawing as is proceeds.

(27) In each of the modes of operation, an overlay of an image to be drawn is overlaid over a piece, of paper or other medium to be drawn on, using the device's camera. Looking at the display of the device, while it is above the canvas, creates a virtual projection that can be traced. This enables the user to create realistic looking artwork with perfect proportions, shading, and colors. Various effects can be applied to an image to change it as it is drawn. For example, the application can combine multiple images into one drawing, such as placing an animal's head on a person's body. The application can be used to write intricate lettering on anything or to create anamorphic drawings that look 3D.

(28) As disclosed, the method can be an application running on a device that has a processor and memory. The device also has a camera and a display. Any image analysis is performed by the processor under control of the application. The application allows a user to create realistic drawing or paintings of any size, take step-by-step lessons to learn to draw without the application. It should be noted that any picture stored on the device can be used for drawings or lessons. The application also provides filters to apply to the images to make drawing easier. Additionally, drawings can be shared using the Application. Finished drawings can be uploaded to a library and shared with other users allowing other users to download and use the drawings as templates.

(29) According to one aspect of the invention, there are video tutorials on how to use the application, which is available under the trade name Da Vinci Eye. The video tutorials are stored on a third party server and accessed by the device. In one embodiment, the drawing tutorials are downloaded to the device for viewing. Alternatively, the tutorials are links to media on a server. It should be noted that the tutorials can also be text documents.

(30) It is to be understood that the invention is not limited to the exact details of construction, operation, exact materials or embodiments shown and described, as obvious modifications and equivalents will be apparent to one skilled in the art; for example, the entire cantilever strap could be provided with a shock absorbing pad disposed upon its lower surface. Accordingly, the invention is therefore to be limited only by the scope of the appended claims. While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention.
