Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    This invention relates generally to portable electronic and computing devices that interface with an outboard computer and display content and imagery on an attached display (screen) and, more specifically, to “intelligent” clothing and such devices that are worn by the user, as well as any device involved in the visual display of electronic content, including advertising.  
           [0003]    2. Description of the Related Art  
           [0004]    As portable and hand-held technological devices become more integral in people&#39;s lives, apparel and accessory designers are adding features to accommodate the new requirements. There are special pockets in shirts and bags for mobile phones, laptop carrying cases that look like purses and belt clips for CD players. This trend is evolving into a new industry, “smart clothes” or “wearable electronics.” These products involve the sophisticated practice of integrating technology and apparel, thereby increasing the utility of the clothing. Instead of having a pocket in a jacket for a phone, “smart clothes” have speakers built into the hood or a microphone integrated into the collar. “Wearable electronics” is a fledgling industry. Currently, smart clothing is focused on improving utility in the following areas: Health sector for clothes that can monitor vital statistics; information and communications sector for incorporating common electronic devices into clothing; and industrial sector for improving efficiency and communications on the job.  
           [0005]    It is desirable to project an individualized message, design, or moving animation on an article of clothing, while retaining the ability to change the displayed imagery to new designs at any time for enabling content to be controlled and changed remotely during use.  
         SUMMARY OF THE INVENTION  
         [0006]    The present invention relates to a method and apparatus for displaying digital images on an article worn by a user to allow for clothing of all types to display digital information. A screen that can display computer-generated animations can attach to clothing. The screen can be thin, lightweight, and flexible for integration with the article of clothing. The screen can display clear, sharp static and moving images. The visual content displayed on the clothing can be changed by a user by using a wired interface to a computer or by receiving the content via a short- or long-range wireless transmission.  
           [0007]    Components of the system include: a wearable article having a display attached to the article, means for generating an image and means for displaying the image. Particular components can include a microcomputer, power source, onboard battery, software for driving the display, wired and/or wireless computer hardware interface, personal computer-based software for loading images into an on-board computer, and Internet-based tools for selecting and creating images to download and play on the display.  
           [0008]    In typical operation, a user establishes a connection to a remote programming device through a connection method. Using software installed on the remote programming device, the user can select an image content file to be displayed on the article. The image content file can be loaded into read/write memory of the microcomputer. The computer can be disconnected from the wearable article and the article would be ready to display the selected image. The user would then put on the article and activate the system to display the selected image on the screen attached to the article.  
           [0009]    In addition, the present invention provides a method of creating or changing images, delivering program med image content to users and sharing images among users. Users can establish a connection between a remote programming device, such as a personal computer, and the microcomputer through which connection they can transfer image content to display on an article to be worn by a user. The user can then terminate the connection with the remote programming device and display the content on the display while wearing the display.  
           [0010]    Alternatively, the article can automatically receive broadcast image content sent to it via a short- or long-range wireless connection. In this mode, an image could be transmitted to the article from a remote programming device while the article is being worn and operated by the user. For example, this embodiment is useful for displaying advertising messages on garments worn by athletes or fans at a sporting event.  
           [0011]    The invention will be more fully described by reference to the following drawings.
