Abstract:
A method for providing interactive self-supporting screen with scalable flexibility. Such a support combined with a flexible computer screen enables reliable touch, writing, mobile drawing, accurate selection, and virtual typing without requiring desk or table space. A flexible screen when rolled up will provide a reduced footprint device for storage or transport and the selective deployment to the required size as the operator desires. Consisting of Protective layer (Flexible-paper feel surface, can be touch enabled), Organic Light Emitting Display (OLED) layer, back light layer (if required), Backing (flexible, slat seam filling; blotter feel), Slats or slabs (Curtin or blinds like), and pullout, telescoping, or swing out cantilever supports.

       BACKGROUND  
       [0003]     1. Field of Invention  
         [0004]     345/169  
         [0005]     This invention relates to the field of computer, specifically to an improved computer input method.  
         [0006]     2. Description of Prior Art  
         [0007]     Initially computer design implementations were temperature and humidity sensitive and as such were constrained to environmentally controlled spaces. Inputs for computers began with crude and indirect devices such as switch panels, basic enunciators and paper tape. As input and support technologies have evolved terminals have moved into rooms, desks and with wireless networks; outdoors. Inputs have evolved with mice, voice, touch panels, and color. Further advances combining radio transmitters and receivers with digital signal encoding allow devices to communicate as if they are physically connected.  
         [0008]     Touch Panels (either glass, membrane, capacity, resistive, optical or radio frequency) over Liquid Crystal Displays are the most natural human-computer input; a replacement for the clipboard as it was. Touch Panel such as U.S. Pat. No. 5,062,198, authored by Sun, titled; “Method of making a transparent touch screen switch assembly” dtd, March 1991. In Sun&#39;s disclosure small diameter polymer particles provide a spacer for separating layers of a touch screen, reducing bulk in a touch screen and allowing rolling up of screens.  
         [0009]     Additional panels, for reference, are further discussed in Examples of switch assemblies having membrane touch panels are disclosed in the following U.S. Pat. Nos. 3,617,666; 3,668,337; 3,722,086, 3,798,370; 3,911,215; 4,017,697, 4,431,882; 4,471,177; 4,700,025 4,786,767; 4,818,827; 4,864,084  
         [0010]     Many alternative methods are discussed for the implementation of “viral paper”. The goal is to provide writing and drawing surface as much like paper as possible and capture these data with the ability to be saved and changed. Of particular importance is the ability to import information and add to or subtract from while mobile.  
         [0011]     Existing Liquid Crystal Displays, Plasma and similar technologies configured as computer displays (e.g. computer tablets and Personal Digital Assistants) perform their jobs well; a display surface for written word, drawings, pictures. These devices can be backlit, reflective and transflective technologies enable such displays to be operated in the dark or direct sun light. These technologies suffer from their bulky nature, high weight, and high power consumption and tend to be fragile.  
         [0012]     Many of the negative screen characteristics mentioned above are corrected through the technology developed by Tang and VanSlyke, Organic Electroluminescent Diodes, Eastman Kodak, July 1987. Screens designed with this technology using flexible sheets for display screens, instead of rigid types (glass) are considerably less bulky, much lower weight, power and less fragile.  
         [0013]     Methods of manufacturing for Organic Light Emitting Diodes (OLED) displays is discussed by Yamazaki in U.S. Pat. No. 6,528,951 discloses an OLED with temperature stable design for consistent light levels. Kim presents in U.S. Pat No. 6,524,884 additional fabrications approaches. Kim also discloses in U.S. Pat. No. 6,506,616 additional techniques for construction of OLED displays.  
         [0014]     The most amazing capability of this OLED technology allows a screen to be “rolled up” as a window shade and with a computer connection can be rolled out to act as full color display. This technology also has excellent viewing properties and consumes much less power then LCD, Plasma or Electro-luminescence panels. Designers of OLED technology systems envisioned a world where OLED screens would be rolled into housings that contained the computer systems, batteries and communications. Additionally, these OLED screens would be rolled out where needed to be read like a reusable newspaper. When intensive review and comments are required screens would be placed on available surfaces for discussions, comments, highlighting, and so forth.  
         [0015]     This makes perfect sense but falls short in many mobile applications where no such surface is available.  
         [0016]     Moreover, when a touch screen (flexible) or radio located or infrared located technology is combined with an OLED the power of the touch (selection, drawing, writing and typing (virtual)) cannot be exploited without a flexible, configurable support system  
         [0000]     Objects and Advantages  
         [0017]     Accordingly, besides the objects and advantages of the Roll Out Touch Screen Support System (ROTS3) process described in my above patent, several objects and advantages of the present invention are:  
         [0018]     (a) Mobile operator interface without a need for auxiliary support;  
         [0019]     (b) Improved commenting and note taking for mobile operators;  
         [0020]     (c) Deployable and scalable display (telescoping) for specific tasks;  
         [0021]     (d) Compact footprint for transportation when not in use;  
         [0022]     (e) Advanced functions available within approximate size of a personal digital assistant or cell phone;  
         [0023]     (f) Facilitate a rotate-able display as in landscape or portrait display formats;  
         [0024]     (g) Efficient power usage and long battery life;  
         [0025]     (h) Supports peripherals such as camera, speakers, microphone and others;  
         [0026]     (i) Compliments other technologies such as PDAs, cell phones, and wearable computers for additional benefits of convenience and functionality.  
       SUMMARY  
       [0027]     In accordance with the present invention, Roll Out Touch Screen Support System (ROTS3), features a configurable support system for comfortable writing, drawing, typing, and selection for any application from paper to a computer display. Specifically, an OLED screen combined with a touch panel (either flexible membrane, radio frequency (RF), or optical technologies can be used) in a ROTS3 offer a satisfying and complete computer interaction for operators without the necessity of auxiliary support. A screen is considered rollable in the sense of the present invention when the screen can be wrapped around an armature or spring loaded mechanism and pulled out, away from the armature for viewing and interacting and subsequently stored by rewrapping screen around armature.  
         [0028]     Accordingly, several objects and advantages of this invention are the flexibility (size may be selected by operator as needed and stowed with a minimal foot print when not required), support and feel for user convenience and comfort for the operator. Types of support for flexible screens can be as simple as a plastic backing, swing or slide out support, to a seamless, reinforced support mechanism. Additional layers may be added for protection in hostile environments, backlighting for low light applications, tear-off screens for issuing receipts or tickets, any operation where an operator interacts and on multiple size input or outputs. Touch screen technologies weather capacitive, resistive, RF, or optical will when combined with flexible screen technologies and the present screen support system will facilitate dramatic improvements in mobile task performance. Still further objects and advantages will become from a study of the descriptions and drawings.  
         [0029]     A particular application yielding additional combining wearable computers such as U.S. Pat. No. 6,137,675, Perkins, dtd. November 2000 produces advances allowing wearers to perform without any support facilities or even desks, tables or physical supports. The subject matter of which is hereby incorporated by reference in it&#39;s entirety into this disclosure.

       DETAILED DESCRIPTION  
       [0050]      FIG. 1  is a perspective drawing of a Roll Out Touch Screen Support System housing in accordance with this invention, showing the front, side and base of the housing. Shown in this basic configuration a protective housing  101  contains the roll out screens and support electronics. Housing  101  has a slot  103  (shown under screen  107 ) that runs the length of housing  101  to facilitate the screen deployment and stowing. A support Arm  105  (right) and a support arm  106  (left) are shown folded in and when deployed will provide support when swung out for a roll out screen  107 . A pull handle  108  is provided to enable deployment of screen  107 .  
         [0051]      FIG. 2  is a perspective drawing of a Roll Out Touch Screen Support System housing in accordance with this invention, including a typical configuration and mounting. Housing  101  has added to it devices as might typically be included in a rolled up (screen not deployed) application. Specifically, an auxiliary view-port  109  allows viewing of a portion of screen  107  when stowed inside housing  101 . This allows display of a picture  111  (such as in teleconferencing), an area for virtual (soft control) navigation  113  (for web browsing and data navigation), an area for an enunciator list  115  (i.e. notes, to do list etc.), an area for a virtual keypad  117  (dialing, data entry, etc.). Additional functions include a camera  110 , a set of speakers  112  (one or more, left and right), and a microphone  114 . In this view a Roll Out Touch Screen Support System presents the operator with a functional collection of devices for mobile computing.  
         [0052]      FIG. 3  is a perspective drawing of a Roll Out Touch Screen Support System housing in accordance with this invention, with touch screen support arms open. Housing  101  is shown with support arms  105  and  106  telescoped out or deployed revealing a support hinge  123  (right) and support hinge  125  (left). In this configuration the roll out screen  107  will be supported by arms  105  and  106  when deployed. Position locking slot  127  (right) and position locking slot  129  (left) are provided to secure screen  107  by capturing handle  108  with a handle end  108 L (left) and handle end  108 R (right). Arms  105  and  106  can be rotated to desired opening and secure screen at selected viewing size. A simple cam follower arrangement can be used to synchronize deploying arms  105  and  106  with handle  108  enabling a single motion to deploy screen  107  and telescope arms  105  and  106 . A rotary potentiometer sensor  123 S such as P12426CT from www.digikey.com is mounted below hinge  123  to inform an OLED display driver  151  ( FIG. 6A ), how large to make screen viewing area As an example if arm  105  is folded in against housing  101  sensor  123 S reads 0 and driver  151  will only illuminate the area of viewport  109  ( FIG. 2 ) or minimum. Video drive flexibility will allow screen to be configured as PDA, cell phone (with soft keys) or as operator requires. Returning to  FIG. 3 , when arm  105  is partially extended sensor  123 S reads 50% value and display driver  151  illuminates ½ or medium display on screen  107 . When arm  105  is fully telescoped out sensor  123 S reads 100% of value and display driver  151  illuminates entire display on screen  107  (as in  FIG. 4 ) or maximum. As in  FIG. 2  driver  151  will allow operator to select and customize display functions as required by tasks or needs of operator.  
         [0053]      FIG. 4  is a perspective drawing of a Roll Out Touch Screen Support System housing in accordance with this invention, where arms  105  (shown below screen  107 ) and  106  are open and screen  107  is extended for use. Housing  101  is shown with screen  107  deployed out over arm  106  with handle  108  and end  108 L holding screen  107  in slot  129  (not visible is end  108 R is secured in slot  127 ). Handle  108  is shown held in position by slots  127  and  129 .  
         [0054]      FIG. 5  is a perspective drawing of a Roll Out Touch Screen Support System housing in accordance with this invention, with touch screen support arms open and OLED screen and touch panel extended and rotated for alternative orientation. Housing  101  is shown with arm  106  extended and displaying a greek&#39;ing (pseudo characters, not meant to be read, merely indicators) as in  FIG. 4  with 90-degree rotation of screen  107  characters. This feature, provided by most video driver chip sets (typically called landscape; while a portrait configuration is default), allows greater flexibility and adaptation to various tasks. A soft-key arrangement located within viewport  109  will enable operators to select and assign video driver to viewing orientation (landscape or portrait) and arrangement or function to best facilitate task support. In this illustration view port  109  and screen  107  greek&#39;ing in display are reassigned as for such as chart monitoring. Additionally, driver  151  ( FIG. 6A ) will allow deployed screen  107  to be viewed as a keyboard and data may be entered through touching virtual keys with a touch screen  167  ( FIGS. 8A and 8B ). Returning to  FIG. 5  screen  107  may be configured as a drawing review, correction, updating device allowing field personal to display and review complete drawings in the field for remote input and updating. Further, driver  151  will allow information displayed on screen  107  to be rotated for personal viewing or collaborating with others, such as in the field where differences in “as built” structures and drawing specifics discussions.  
         [0055]      FIG. 6A  is a perspective drawing of case with internal modules for a Roll Out Touch Screen Support System. Housing  101  is opened for internal viewing and screen mechanism is removed and shown to the left. The base of slot  103  is shown for descriptive purposes above electronics. Looking through view port  109  and opening on top a rectangular tension-retaring slot  135  in right end can be viewed. A left end support hole  134  for idler is shown dotted for discussion and visualization. Roll up mechanism  133  has corresponding spring retainer  138  (in the shape of a rectangular slot matched to fit into slot  135 ) on right end and a support pin  139  on left end (for mounting in hole  134 ). Handle retaining ends  108 L and  108 R are shown for visualization. A tensioning spring  137  (is shown without screen retainer tube  133 R;  FIG. 6B ) when installed is meant to be preloaded to close screen  107  when not locked as in  FIG. 4 . Returning to  FIG. 6A , modules to operate this embodiment are a battery  140 , a power supply  141 , a serial interface  143  (i.e. 1394 and/or USB module), an Input/Output panel  145  (for connectors), a radio interface  147  (i.e. 802.11a/b, Bluetooth, 1394 RF), a processor module  149 , a digitizer  149 D for determining pen position on screen, a memory module  149 M for storing system information, and an OLED display driver  151  card (i.e. Kodak OLED driver kit). Typically, interface  147  would be bidirectional and include security encryption and similar precautions to prohibit incursions by undesirable parties.  
         [0056]      FIG. 6B  is a perspective drawing of the internal roll up mechanism  133 . Roll up mechanism is disassembled to reveal a screen retainer tube  133 R with a screen-mounting slot  133 S. Tube  133 R slides over spring  137  and pin  139  has a cap back that will engage tube  133 R when assembled. Tension retainer  138  with tube  133 R installed and support pin  139  will secure spring assembly and when installed in housing provide roll up tension when screen is deployed.  
         [0057]      FIG. 7  is a perspective drawing of screen support. A screen support mechanism  153  consists of a series of slats  155  arranged parallel to the housing. A portion of the slats  155  is shown removed in the upper right corner to reveal slats backing. Slats  155  are fashioned of plastic, wood or any material that provides lateral screen support with minimal size and weight are positioned closely together secured to a scrimshaw backing-webbing  157  with glue or similar adhesion method. Handle  108  is configured to guide mechanism  153  over arms and secure screens and slats when deployed and stowed. Slats  155  are shown to provide support and enable rolling up into housing.  
         [0058]      FIG. 8A  is a perspective drawing of screen  107  layers. Enhancements are shown for improved operator experience. An under-liner  161  is fashioned from such as silicone with mesh reinforcement to provide more complete isolation from slats  155 . An optional liner sheet-backlight  163 , fashioned from electro-luminescence material from MetroMark Minetonka, Minn. will provide backlighting for special requirements. An OLED screen  165  is available from Kodak, Philips Electronics, Samsung, or Universal Display Technologies. A touch screen  167  is shown examples are available from Touch Technologies or Universal Display Technologies. Alternatively, infrared or radio positioning touch systems will not require a physical screen, just x and y positioning sensors, available from TouchSystem in Hutto, Tex. or Cross technologies. Additionally, an optical pen touch system available from Toshiba/Matsushita can feature an optical sensor in a protective shield, these will minimize light loss from the OLED screen and minimize glare. A protective shield  169  is included for use in hazardous environments; a clear acetate, polymer sheet, or any non-opaque material will perform this function. Webbing  157  under slats  155  binds slats  155  into a structure. A set of straps  159  fashioned from elastic are shown, these are compensators for equalizing tension to top layer screen  167  and slats  155  as they will have different distances to travel when being deployed and stowed. The strap  159  is shown secured to screen  169  on right side and ready to secure to screen  169  on left side. Attachment of strap  159  underneath is shown in  FIG. 8B . Depending on screen configuration whichever screen is on top can be used to attach straps  159 .  
         [0059]      FIG. 8B  is a side view of roll up system and compensation. A basic version showing screen  167 , screen  165 , and slats  155  is shown extended from idler  139 . Strap  159  is shown secured to screen  167  and underneath to slats  155  at attachment points  158  (X 2, top and bottom, both sides) to provide tension compensation. Attachments can be with appropriate glue or pressed on with heat during assembly.  
         [0060]      FIG. 9  is a perspective view of housing  101  with screen  107  extended while being held by an operator&#39;s hand  154 . When the present invention is utilized in this manner operators are aided in performing tasks and can interact with a screen with the approximate dimensions of a laptop or tablet computer while transporting and carrying only a device the size of a PDA. The ability to view, type, or write on screen  107  while holding housing  107  affords the convenience of a rollout screen with the added capability of supported input without the need for an auxiliary table or stand.  
         [0061]      FIG. 10A  is a perspective view of a flexible arm attached to a Roll Out Touch Screen Support System. In this view housing  101  has an adapter mounting cup  170 . Cup  170  is configured to allow an arm adapter  172  such as a male hose to female pipe adapter part # 8550-182 from www.cedarburg.com to rotate within cup  170  so arm will feature a variety of positions in relation to housing  101 . Adapter  172  is pined with a pin  171  to cup  170 . A flexible arm  174  is connected to adapter  172 . Arm  174  can be comprised of an appropriate number of hose segments from www.cedarburg.com part # 8450-11 for the desired length. An arm termination adapter  176  is shown connected to arm  174  for connection to support base. Adapter  176  is another male hose to female pipe adapter part # 8550-182 from www.cedarburg.com.  
         [0062]      FIG. 10B  is a perspective view of a flexible support arm attached to a support to be belt mounted. The arm  174  is shown connected to adapter  176 . Adapter  176  is shown mounted in an opening in belt base  178 . Adapter  176  is pinned inside base  178  (not shown) and allowed to rotate ˜110° from closed position. A location for a battery mount  179  is available for power to electronics in housing  101  or to power belt devices. When power is routed to housing  101  from base  178  the elements of arm  174  are hollow and small gauge power cables (typically containing capacity sufficient to power a PDA or cell phone) can be run inside arm  174 .  
         [0063]      FIG. 10C  is a perspective view of a Roll Out Touch Screen Support System, flexible arm, and belt. A belt such as U.S. Pat. No. 6,137,675 is shown as belt  180 . Base  178  is shown mounted on belt  180 . Typically base  178  would slide over or clip to belt  180 . Belt  180  has vertical structure that base  180  can attach to for stability and support of devices. A cantilevered arm such as arm  174  attached to base  178  will support housing  101 , with and without screen deployed, and facilitate stable operator interaction.  
         [0064]      FIG. 11  is a view of a Roll Out Touch Screen Support System mounted on articulated arm of a wearable computer. An operator  182  is shown wearing a belt  180  with arm  174  and housing  101  with screen  107  deployed. Operator  182  is positioned to share information displayed on screen  107 . Operator  182  has a choice of positions and can work with the display close in to allow privacy from prying eyes. The choice of operating positions and the ability to enjoy a screen the size of a laptop or tablet while working hands free is unique to the present invention. The touch capability of the system will facilitate operator (or others if operator desires) to enter or correct information while still being mobile. This capability is very important to operators who must go where the task is. For example a architect-operator that has to go on site to review a site problem can bring the drawings and correct or comment for “as built” realities. Additionally, the radio-internet communication capability of the present invention will assist operators to obtain, modify, or correct drawings from anywhere to anywhere. The camera function of the present invention can also assist in documenting “as built” situations. A conference call with video and drawings will not be difficult even from the site of the situation. Presently construction sites still suffer with red line drawings and slow corrections, costing millions of dollars annually. One practiced in the arts of site engineering should immediately see the potential benefit of this embodiment.  
         [0065]      FIG. 12  is a view of a Roll Out Touch Screen Support System on a belt with arm folded for stowage. Belt  180  is shown without a wearer (operator) for visualization.

         [0068]     Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.  
         [0000]     Advantages  
         [0069]     From the above description a number of advantages or my Roll Out Touch Screen Support System (ROTS3) become evident: 
        (a) Interfaces for mobile operator without auxiliary support;     (b) Commenting and note taking for mobile operators is improved;     (c) Specific tasks can be scaled to specific screen size;     (d) Improved transportation when not in use;     (e) Personal digital assistant or cell phone basic functions available when screen is stowed;     (f) Long battery life with efficient power usage;     (g) Peripherals such as camera, speakers, microphone and others are supported;     (h) Flexible incorporation of advanced devices increases functionality and operator utility.        
 
         [0078]     In addition ROTS3 compliments other technologies such as wearable computers for additional benefits  
         [0000]     Operation  
         [0079]     In operation one uses the ROTS3 as when pulling a paper towel from a roll or as a window shade. An Operator will partially view OLED screen and touch panel in the preferred embodiment when the screen is fully rolled up into the housing. This embodiment allows the operator to typical phone, calendar, and alert notification without deploying the screen. This minimal foot print configuration is for multi use devices such as a Personal Digital Assistant plus (PDA)/ cell phone (voice over IP or cell), camera when “rolled up”. Touching the upper left area in  FIG. 2  of port  109  will turn device on The plus part of this embodiment is the functionality made available when the flexible screen and touch panel are “rolled out”. Any flexible screen, membrane or similar sheets can be used over the ROTS3 to provide support anywhere without additional support or braces. Even rigid panels (for example; folding screens) may enjoy the configurable functionality of ROTS3 as applications are discovered. When as operator rolls out a screen with ROTS3 incorporated as in the preferred embodiment any function can be displayed and interacted without additional support.  
         [0080]     When an operator completes the current task he/she may continue to the next task or roll up the ROTS3 and stow or monitor the closed configuration and enjoy the portable-functionality with out the inconvenience of such as a laptop computer. When an operator desires to change display orientation; two taps on the upper left area in  FIG. 2  of port  109  will cause display to offer operator choice of landscape or portrait formats. Smaller foot prints for the ROTS3 housing are envisioned with any of the following made remote from the housing; PDA available when rolled up, processor/computer, battery, wireless and camera. Such an implementation can be connected to a host by Low Voltage Differential Signal, (LVDS), as a thin client or with IEEE 1394 type connection. In design for operation the ROTS3 system is intended to provide support for screens, touch devices, and any medium requiring a supportive backing.  
         [0081]     Additional functionality for mobile individuals can be achieved by mounting ROTS3 housing on arm supported by U.S. Pat. No. 6,137,675. Such an arm on a structural belt will enhance ROTS3 support with hands free operation and transport.  
         [0000]     Conclusions, Ramifications, and Scope  
         [0082]     Accordingly, the reader will see that ROTS3 support of this invention can be used to improve the experience of operators engaged in performance of tasks. In addition, operators using ROTS3 have more freedom of movement as no auxiliary support is required. Furthermore, the simplified interface will make this technology used more often by operators. Additionally, scalability of the screen size will enhance the operator&#39;s experience as the operator deploys only the required size device. Further enhancing the operator&#39;s experience is the simplified transportation with the small footprint when screen is stowed. Additionally, basic functions are available to the operator in the stowed configuration. Efficient power usage will remove concern from operators or allow more functions for the same power. Embodiments also allow early leading development technology adapter devices such as PDAs and cell phone to be incorporated into the present invention. This embodiment will allow operators to have the greatest capabilities with the minimum time lag, at the lowest costs. As a bonus peripherals are supported and can be designed into the packaging. To further enhance the operator&#39;s experience ROTS3 can be combined with wearable computers and task performance can be further improved and transportation is almost invisible. The advantages and flexibility afforded by my ROTS3 can save operators time energy and improve productivity.
