Description

This application claims the benefit of PPA Ser. No. 61/789,573 filed 2013 Mar. 15 by the present inventors, which is incorporated by reference.

BACKGROUND Prior Art

The following is a tabulation of some prior art that presently appear relevant:

U.S. Patent Patent Number Kind Code Filing Date Patentee US20130275907 A1 2011 Oct. 14 Hannes Lau and Christian Sax US20070036603 A1 2004 Sep. 22 Marek Swoboda

Smart phones are being increasingly used for sending text messages either through text messaging, email, or alternative methods. However, in most cases the texting interface is either limited to a miniaturized keyboard or a soft keyboard. In either case users are limited to using two thumbs when entering text. This limitation decreases typing speed significantly.

There are many different forms of computer keyboards for computers and computer-driven appliances, including those with static hard keys, static soft keys, and dynamically mapped soft keys on a touch-sensitive surface.

When using either of the keyboards with mechanical keys or with static soft keys, our fingers have to conform to the position of the keys; keys are not customizable to the posture of our fingers. Different operators have different hand sizes and hand postures. Keyboards with static keys can't be customized to individuals' needs. These types of keyboards put stress on the wrists of the operator.

Computer keyboards with dynamically mapped soft keys provide operators the flexibility to keep their wrists straight. Patent US20130275907 A1 to Hannes Lau and Christian Sax, 2011 Oct. 14 references such keyboards. However, these keyboards with dynamically mapped keys use a flat keyboard, which force the hands of the operator to rest on the palm side of the wrists, as if using a conventional flat keyboard. This limitation squeezes the median nerve which may lead to developing Carpal Tunnel Syndrome.

Another form of computer keyboard in patent US20070036603 A1 to Marek Swoboda, 2004 Sep. 22, describes a keyboard with keys on the back surface. Additional mechanical keys are built on the left and right edges of the keyboard. Both soft keys and mechanical keys are statically mounted or assigned on the back surface and on left and right edges. Keys on the back of the keyboard are visible through the top transparent surface. Operator looks through the device to see and then manually activate the keys. This limitation prevents proper use of the top surface. For example, a display screen can't be efficiently used to show entered text or display a running program. Activating keys mounted on the left and right edges are not as comfortable as if they were mounted and activated on the front surface.

I have found that keyboards with keys on the back where the back and the front surfaces are parallel with each other are harder to use than if the two surfaces were in an angle. I will discuss this in more detail later.

On the other hand, keyboards with dynamically mapped invisible soft keys can't be used without an external monitor. Operators need to see what they type and be able to correct typos and grammatical errors. Further improvements are required.

Advantages

Accordingly, several advantages of one or more aspects are as follows:

Mobility and portability allows operators to stand, walk, or do other activities while, typing on the keyboard, and, a sound module or other notification methods alert operators when detecting typos or other errors, or, transcribing voice to text and computer commands. Faster speeds, greater efficiency, and healthier body and finger posture is achieved when keys are dynamically mapped onto the back of an embodiment, and a limited number of keys assign on the front of the embodiment, where thumbs activate the front keys and other 8 finger activate the back keys.

These and other advantages will become apparent from the ensuing description and accompanying drawings.

SUMMARY

In accordance with one embodiment, a portable keyboard for a computer or a mobile device provides increased speed, functionality, and mobility. Use of dynamically mapped keys on back, front, and edges of an exemplary embodiment provides healthier posture for the hands and fingers of the operator. Sound and other media are incorporated to notify the operator and to transcribe voice into text and computer commands for greater efficiency.

 DETAILED DESCRIPTION FIGS. 1 to 6—First Embodiment

FIG. 1 shows the front of the first exemplary embodiment. This embodiment provides a touch-sensitive screen or a touch-screen 105, a plurality of mechanical keys 109, 110, 111, 112, and 115, a plurality of soft programmable keys 122, 123, 124, 125, and 128, two speakers 103 and 120, two microphones 108 and 114, a plurality of status or indicator LED lights 117, and one visible light sensor 119 on the front surface 104. Touch pads 102, 106, 116 and 121 located on the right and left curved edges 101 and 118 of the embodiment are capable of detecting ranges of pressure levels from the thumbs and the hands of the operator. Adjustable legs 107 and 113 help keep the embodiment in a comfortable position for use.

The touch screen is capable of detecting at least the touch of two thumbs simultaneously and to display a plurality of icons, a plurality of running program windows, as well as text boxes and a plurality of programmable soft keys.

FIG. 2 shows the back of the embodiment with two bottom surfaces 201 and 214, each with touch-sensitive surfaces or touch pads 202 and 213 that are capable of detecting up to 4 fingers or a total of 8 fingers simultaneously. Additionally there is a plurality of invisible environment, motion and position sensor (not shown).

Both touch pads are capable of detecting different ranges of pressure levels. Each pressure range describes a specific action, for example, tapping with a finger, touching or resting on the touchpad, sliding or moving a finger or a plurality of fingers on a touch pad, squeezing a touch pad with the palm of one hand, pressing harder on a touch pad with a finger, etc.

Most computer keyboards have standard alphanumeric keys including home keys A, S, D, F, J, K, L, ;, other alpha keys adjacent to the home keys, numeric keys, punctuation keys including mathematical operators, and a set of special keys including function keys. An example of special keys is Tab, Caps, Shift, Ctrl, Command, Alt, Scroll, Delete, etc. Recent computer keyboards, in addition to these keys include additional keys to activate and control programs running on the host computer. For example a computer keyboard may have keys to open a web browser, a menu, and start and stop keys for playing music, etc. The adjacent keys of a home key are activated by the same finger that activates the home key. For example as shown in FIG. 2, key 203 and key 205 are the adjacent keys of the home key 204 on a QWERTY layout. There are several keyboards with different layouts including QWERTY, Dvorak, Arabic, etc.

The first embodiment provides at least: a housing, a non-volatile storage media, a volatile storage media, a source of rechargeable power to provide electricity when operating wirelessly, a method to communicate with the local and/or remote hosts, a first program to customize and build new computer layouts, a second program for choosing and activating a keyboard layout, a third program for obtaining the initial contact position of fingers when rested on the pads and the contact position of fingers when extended and retracted, a fourth program for detecting normal operation and activities performed by the hand of the operator, for remapping the interface elements on the touch pads as fingers move or shift from the initial position, and a fifth program to activate a sound module and/or other methods of notifying operator when typos, grammatical or other errors are detected, to transcribe voice into text and computer commands, and an electronic module to run those programs, generate codes, display information on the touch screen, and transmit generated codes through a wired, wireless, or both mediums to a locally attached host, and/or to one or a plurality of remote hosts. Other methods of notification include future and currently available including notification methods through vibration and notification through tactile sensation as described at: http://www.ncbi.nlm.nih.gov/pmc/articies/PMC3100092/.

The non-volatile storage media holds the programs and information pertaining to all available keyboard layouts and customized keyboard layouts. These programs are responsible for providing at least BIOS support and to initialize and operate the embodiment.

The keys of keyboard layouts are divided into a plurality of interface groups. The elements of each interface group are comprised of one home key and none, one, or a plurality of adjacent keys. The elements of each interface group are assigned to and activated by one of the fingers of the operator. For example, in FIG. 2 interface 208 representing interface group D is comprised of elements 207, 209, and 210, representing E, D, and C keys, where element 209 is the home key D. Similarly, interface 212 representing interface group F is comprised of home key 211 and several adjacent keys. Element 206 is an adjacent key or another interface group that represents the Enter key. Enter key is one of the special keys.

TABLE 1 Interface Home Home and Adjacent Assigned Group Key Member Keys Hand finger A A Q A Z Tab Caps Shift Left Pinky finger S S W S X Ring finger D D E D C Middle finger F F R F V T G B Index finger J J Y H N U J M Right Index finger K K I K , Middle finger L L O L . Ring finger Semicolon ; P ; / ' Backspace Pinky finger Enter Shift Left Left Space Left Left thumb Space Space Right Right Space Right Right thumb Space Space

Also as shown in FIG. 3, to provide additional comfort for fingers, the back surfaces 201 and 214, and front surface 104 are not parallel with each other. Angle 301 between two back surfaces, and angles 303 and 304 between the front surface 104 and two back surfaces are less than 120 degrees, making the top surface 302 look triangular.

FIG. 4 shows touch pad 213 on back surface 214, where the fingers of the left hand are resting. Contact points 401, 403, 405, and 407 are the areas touched by the Index finger, Middle finger, Ring finger, and the Pinky finger of the left hand respectively. Areas 402, 404, 406, and 408 are the area assigned or mapped to home keys F, D, S, and A (invisible) to be activated by each respective finger.

FIG. 5 shows a set of numeric keys and arithmetic operation keys. Interface group 501 contains elements 502, 503, and 504. Element 503 is digit 5 home key and elements 502 and 504 are adjacent digits 8 and 2 keys.

Operation First Embodiment

Holding two mechanical keys labeled Space for 3 seconds or longer prompts operator to choose one of the programs. Operator may call the first program to customize a layout. As part of the customization, operator may customize each key of a selected keyboard, the functions of touch pads 102, 106, 116 and 121 (FIG. 1) located on the edges of the embodiment, the functions of each mechanical key, and the functions of the soft programmable keys 122, 123, 124, 125, and 126. Operator may choose to assign certain keys to the left or right thumb. Operator may choose to set the number of active fingers, on either touch pad to less than 4 fingers, excluding thumbs. In such a case operator will customize and alter the assignment of keys to each active finger. Each customized layout may be saved at one of a plurality of non-volatile storage locations.

An operator, at the first use of the keyboard calls up the second program and chooses and activates one of the available keyboard layouts or one of the customized layouts. Operator should also call the third program at least once to customize the keyboard to the hands and fingers.

When the third program is called, operator is prompted to follow a series if instruction to detect and register the contact points of each finger at resting position on the touch pads, as well as the contact points of each finger when extending or retracting to tap on other areas on the touch pads, as if typing on the adjacent keys of a keyboard.

For example, when the operator is prompted to rest at 8 fingers on the two touch pads, the third program detects and registers the contact point of the left index finger at resting position and maps the F key to that position. Then through a sequence of prompts, the operator taps on different areas of the left touch pad by extending or retracting the left index finger as if typing on the adjacent keys R, V, T, G, and B on a QWERTY keyboard. The center of all contact points or the coordinates of contact points between the left Middle finger and the touch pad are grouped together as elements of the F interface group. FIG. 2 shows interface groups 212 representing F interface group.

As shown in FIG. 4, for example, the small area 402 is assigned on the touch pad 213 to the F key (invisible) an the index finger of the operator activates it. Area 402 is the center of contact point 401 which is the contact point between the left index finger an the touch pad 213. Since the contact points are larger than mapped areas, operator can easily tap on mapped areas and activate respective keys. Mapped keys are invisible soft keys. Each special key, for example, Ctrl, Shift, Delete, etc may be mapped to a mechanical key, static soft key, dynamically mapped soft key, or mapped to a plurality of keys simultaneously.

Once all contact points or coordinates of all fingers are registered, the third program maps each of the contact points to a key. The third program also calculates the distance between each adjacent key and the home key, and the distance between same adjacent key and the next home key. For example, as shown in FIG. 6, the distance between adjacent key 601, representing key and home key 602, representing key F, as well as the distance between key 601 and home key 603, representing key F are calculated and saved together with their coordinates in the non-volatile storage media. The information stored in the storage media is available to the fourth program.

The fourth program is the main program that runs automatically ail the time to detect activities performed by the hands of the operator and to generate codes relative to each activity on a touch pad or a touch screen. For example, when the operator taps on the mapped location of key D with the left Middle finger, a character code representing letter d is generated. If the operator was pressing and holding the Shift key with right Pinky finger while performing the same action, a character code representing letter D is generated.

As the operator's hands move, the position of the home keys also shift and move. Fourth program recurrently detects the new location of the home keys by reading the contact points of the active fingers whenever they are at resting position. The new position of the home keys are dynamically remapped on the touch pads, With the information pertaining to adjacent keys and their distances from two home keys available, the coordinates of the adjacent keys are adjusted based on the coordinates of the new home keys. Therefore there is no need to detect the position of the adjacent keys.

For example, in FIG. 6, the existing position of two home keys 602 and 603 representing D and F home keys are shown. F key is the neighbor home key relative to D home key. Key 601 is the adjacent key of the D key and is an element of the D interface Group, Let's say, when we ran the third program, the distance between the E and the D keys was 12 mm and the distance between the E and F keys was 16 mm.

Let's say that the left hand of the operator moved and shifted forward. In this example in Fi the contact point of the left Middle finger 602 moved forward slightly more than the left index finger 603. The fourth program detects the new contact points of the left Middle finger 605 and left Index finger 604 and remaps D and F keys on the left touch pad accordingly. It also calculates and updates the coordinate of the E key 601 and maps it at the location 606 which is 12 mm from the new position of the D home key and 16 mm from the F neighbor home key.

Operator's left and right thumbs activate the mechanical keys located under the front touch screen, and any soft programmable key mapped on the touch screen.

The fifth program, at operators request, reads every letter or word, and notifies the operator with distinct sounds when typos, grammatical errors, or other errors, are detected. The program may use other forms of notification, for example vibration or displaying a message on the touch screen. The program may at operators request record and transcribe voice into text and computer commands, letting the operator only correct errors made during the transcribing process.

There are different modes of operation include Extended Mode, Arrows Mode, Multi-Mice Mode, etc, Other modes of operation may be achieved by creating new customized layouts. The operator may activate any of these modes one at a time by either pressing the mode key 111 in FIG. 1, or by touching one of the programmable soft keys located on the touch screen, one that is programmed to perform the same function. Each mode associates different keys with the fingers of the operator.

In Texting Mode, as shown in FIG. 1, mechanical keys 109, 110, 112, and 115 represent Ctrl, left Space, right Space, and Alt keys. Also in Texting Mode as shown in FIG. 2, the elements of each interface represent alpha keys or a combination of alpha and a set of special keys.

However in Numeric Mode as shown in FIG. 5 the elements of each interface represent numeric keys and arithmetic operation keys. For example, interface group 501, contains keys 8, 5, and 2 where element 503 is digit 5 home key and elements 502 and 504 are adjacent digits 8 and 2 keys.

Table 2 shows interface groups and associated elements in Numeric Mode. In this mode of operation one or both of the touch pads on back surfaces may be mapped with the same interface groups. For example, interface group 5 with elements 8, 5, and 2 may be associated with the left Middle finger, right Middle finger, or both.

Right Right thumb

Extended Mode provides access to different symbols, functions keys, numbers, and special keys. Table 3 shows interface groups and associated elements in Extended Mode. For example, the interface group D in Texting Mode becomes interface group 3 in Extended Mode. Function keys F3, F13, and digit 3 key become the elements of interface group 3.

Each thumb is assigned to activate at least two mechanical keys located on the front surface under the touch screen. For example, right thumb can activate the two far most right mechanical keys which are map d to digit 0 key and F10 Function key.

In Multi-Mice Mode, both touch pads located on the back of the embodiment become mouse pads. In this mode, one or a plurality of fingers of each hand may control the movements of an independent mouse or perform other activities. For example, by sliding the Index finger of left hand on the left touch pad, operator can move the pointer of the 1st mouse and perform another action by tapping with same finger on the touch pad. Similarly, the Index finger of the right hand may perform the same action as the left Index finger, but to control a 2nd mouse. Additionally, when using 2 fingers, 3 fingers, or even 4 fingers simultaneously, operator may perform one of the common actions of a typical mouse, or simplify and facilitate a process which otherwise may require several steps to accomplish. For example, in a drawing program, by using two index fingers, the operator may grab the two ends of a line, move and stretch it to fit in a new location, which otherwise, the same function would require moving each end of the line one step at a time. In another example, operator may rotate, zoom, and perform other actions on an object simultaneously by using more fingers of one or both hands.

Table 4 shows an example of the functions to be assigned to each finger. As stated earlier, by combining functions of a plurality of fingers, a new function may be achieved. These new functions may extend the functions of currently available computer programs and the programs to become available in the future due to the capabilities of this or other embodiments.

In Arrows Mode, tapping with the right index finger at its resting position will move the cursor or the selected object to the left, tapping with the right Ring finger at its resting position will move the cursor or the selected object to the right, an tapping with the right Middle finger above or below its resting position will move the cursor or the selected object up or down accordingly. Same functions may be achieved by the fingers of the left hand.

Functions of the touch pads located on the left and the right edges of the embodiment may vary when selecting different layouts or different modes of operation. In FIG. 1, touch pads 102 and 121 may be programmed to provide status updates on certain programs when pushed by the thumbs, while touch pads 106 and 116 may be programmed to change the thickness of a pen in a drawing application.

An operator may hold the first embodiment in the air, lay it on a desk, or dock it on a docking station during the operation. As shown in FIG. 1, adjustable legs 107 and 113 help keep the keyboard at a comfortable angle when set on a desk or docked.

CONCLUSION, RAMIFICATION, AND SCOPE

One or more embodiments provide the following benefits individually or collectively:

Mobility and portability provides operators the choice to stand, walk, lie in the bed, or do other activities while typing on the keyboard. With invisible keys on the back of a portable device, which dynamically conform to the fingers of the operators, all the fingers of the operator become active. Hence, increased typing speed, greater efficiency, and healthier posture of fingers, wrists, hands and the body of the operator is achieved.

Versatile and customizable layouts meet the needs of different operators, including operators with less than 10 active fingers. Sound module adds another attribute by detecting and notifying errors and transcribing voice to text and computer commands. Each embodiment, in addition to the functions of an advanced computer keyboard, can activate a plurality of instances of a computer mouse, controlling the actions of several mice in one application program. This enhanced capability provides support for future programs requiring such capability.
