Early hominins first developed speech almost two million years ago. Since that time, speech has evolved dramatically in both complexity and speed. Today, the average person speaks about 150 WPM and comprehends about 275 spoken WPM. Of course, speech is not necessarily permanent. People may speak to each other, but not memorialize their speech.
In contrast, writing is always permanent. Early civilizations developed writing almost 6,000 years ago. Since that time, writing has also evolved dramatically in both complexity and speed. Today, the average person writes about 13 WPM and comprehends about 250 written WPM. Thus, writing speed lags far behind speaking, speech comprehension, and written comprehension speeds.
Typewriters partially resolve that issue. The first typewriter was developed in the late 16th century. Since that time, typewriters, and subsequently keyboards, have improved dramatically. Today, the average person types about 40 WPM, while the average professional typist types about 75 WPM. Thus, even professional typing still lags far behind speaking, speech comprehension, and written comprehension speeds.

Traditional typewriters and traditional keyboards perform character entry in which a user sequentially depresses keys to enter characters such as letters. Each key corresponds to only a single character. Thus, a user may type the word “cat” by sequentially depressing a “c” key, an “a” key, and a “t” key.
In contrast, chorded keyboards, including stenotypes, perform chorded entry in which a user simultaneously depresses keys to enter chords such as syllables, words, or phrases. No key corresponds to a single syllable, word, or phrase, much less a single character; rather, a combination of keys corresponds to a combination of characters forming a syllable, word, or phrase. Thus, a user may type the word “cat” by simultaneously depressing a first key corresponding to both “t” sounds and “k” sounds, a second key corresponding to “a,” and a third key corresponding to both “t” sounds and “s” sounds.
Stenotypes provide quicker data entry compared to traditional typewriters. While a professional typist types about 75 WPM, a professional stenographer types about 180-225 WPM. However, 180-225 WPM still lags the average comprehension of about 275 spoken WPM and about 250 written WPM.
There is therefore a desire to overcome the following shortcomings of keyboards and stenotypes in order to improve beyond 180-225 WPM. First, keyboards perform character entry, but not chorded entry. In contrast, stenotypes perform chorded entry, but not character entry. Thus, both keyboards and stenotypes perform traditional data entry, which is unable to alternate between character entry and chorded entry. Second, keyboards and stenotypes have key layouts that are not ergonomic and are thus less efficient. Third, keyboards and stenotypes have 1D keys that allow a user to depress the keys in one direction to make a single data entry, but do not allow the user to move the keys in other directions to make different data entries.
Disclosed herein are embodiments for fluid chord/character entry. First, a data entry device performs fluid chord/character entry, which is able to distinguish and alternate between chorded entry and character entry. Second, the data entry device may comprise dedicated keys for each finger and thumb so that a user can enter data with comfort and the ability to maintain digital contact. Third, the data entry device comprises multi-dimensional keys, which can move in two or more directions to provide two or more different data entries. With those features, the data entry device allows a user to type over 300 WPM, in other words, to Type at the Speed of Thought®. In addition, the data entry device provides ambidextrous throwover and mouse functionality. Thus, the data entry device benefits stenographers, digital artists, CAD modelers, gamers, disabled people, and the general population in their everyday lives.
The casing 210 may comprise plastic, metal, wood, a polymer, a composite material, or another suitable material. The casing 210 is a single piece formed from a mold or is multiple such pieces bonded together to form the single piece. The casing 210 provides support for the keys 220, the cords 230, and the communications bus 240.
The keys 220 may also be referred to as switches. Though there are 18 keys 220 in the layout shown, the data entry device 200 may comprise 10 keys, 12 keys, 14 keys, or any other suitable number of keys in any suitable layout. Each of the keys 220 may be associated with both characters and chords. The keys 220 are described further below.
The cords 230 communicate data to and from the communications bus 240. The communications bus 240 may be a USB 1.0, USB 2.0, USB 3.x, or USB4 bus. The communications bus 240 communicates data to and from an external device such as the external device 120.
The processor 330 is any combination of hardware, middleware, firmware, or software. The processor 330 comprises any combination of one or more CPU chips, cores, FPGAs, ASICs, or DSPs. The processor 330 communicates with the ingress ports 310, the RX 320, the TX 340, the egress ports 350, and the memory 360. The processor 330 comprises a fluid chord/character entry component 370, which implements the disclosed embodiments. The inclusion of the fluid chord/character entry component 370 therefore provides a substantial improvement to the functionality of the apparatus 300 and effects a transformation of the apparatus 300 to a different state. Alternatively, the memory 360 stores the fluid chord/character entry component 370 as instructions, and the processor 330 executes those instructions. The processor 330 further comprises a library 380. The library 380 maps data entries to characters and chords.
The processor 330 may comprise multiple processors or microcontrollers. For instance, the processor 330 comprises a first microcontroller that receives data entries from the keys 220 on the left side of the data entry device 200, a second microcontroller that receives data entries from the keys 220 on the right side of the data entry device 200, and a third microcontroller that combines the data entries from the first microcontroller and the second microcontroller and processes that data to create an output for the external device 120. The output may be in ASCII format.
The memory 360 comprises any combination of disks, tape drives, or solid-state drives. The apparatus 300 may use the memory 360 as an over-flow data storage device to store programs when the apparatus 300 selects those programs for execution and to store instructions and data that the apparatus 300 reads during execution of those programs, for instance as a computer program product. The memory 360 may be volatile or non-volatile and may be any combination of ROM, RAM, TCAM, or SRAM.
A computer program product may comprise computer-executable instructions stored on the memory 360 that, when executed by the processor 330, cause the apparatus 300 to perform any of the embodiments.
The components of the apparatus 300 may be in different devices. In a first example, the fluid chord/character entry component 370 is in a first device, and the library 380 is in a second device. In a second example, the processor 330 is in a first device, and the memory 360 is in a second device.
At step 405, a first data entry is received. For instance, a user activates one or more of the keys 220 by pushing the keys 220 up, right, down, or left or by depressing the keys 220. The processor 330 receives a first data entry in response to that activation. The first data entry represents all activations of the keys 220 at a first time. The activations may be required to occur within a threshold amount of time.
At step 410, a first determination whether the first data entry is a first character entry or a first chorded entry is made. For instance, the fluid chord/character entry component 370 determines that the first data entry is a first character entry when it receives the first data entry from only one of the keys 220. Alternatively, the fluid chord/character entry component 370 determines that the first data entry is a first chorded entry when it receives the first data entry from at least two of the keys 220.
At step 415, a first output is selected based on the first determination. For instance, the fluid chord/character entry component 370 queries the library 380 to determine a first character corresponding to the first character entry. Alternatively, the fluid chord/character entry component 370 queries the library 380 to determine a first chord corresponding to the first chorded entry. The fluid chord/character entry component 370 then selects either the first character or the first chord as the first output. The fluid chord/character entry component 370 may perform step 415 independent of user selection.
At step 420, the first output is transmitted. For instance, the fluid chord/character entry component 370 transmits the first output to the external device 120.
At step 425, the first output is displayed. For instance, the external device 120 displays the first output on a screen of the external device 120.
At step 430, a second data entry is received after the first output is transmitted. The second data entry may also be received while or after the first output is displayed. For instance, a user activates one or more of the keys 220 by pushing the keys 220 up, right, down, or left or by depressing the keys 220. The processor 330 receives a second data entry in response to that activation. The second data entry represents all activations of the keys 220 at a second time. The activations may be required to occur within a threshold amount of time.
At step 435, a second determination whether the second data entry is a second character entry or a second chorded entry is made. For instance, the fluid chord/character entry component 370 determines that the second data entry is a second character entry when it receives the second data entry from only one of the keys 220. Alternatively, the fluid chord/character entry component 370 determines that the second data entry is a second chorded entry when it receives the second data entry from at least two of the keys 220.
At step 440, a second output is selected based on the second determination. For instance, the fluid chord/character entry component 370 queries the library 380 to determine a second character corresponding to the second character entry. Alternatively, the fluid chord/character entry component 370 queries the library 380 to determine a second chord corresponding to the second chorded entry. The fluid chord/character entry component 370 then selects either the second character or the second chord as the first output. The fluid chord/character entry component 370 may perform step 440 independent of user selection.
At step 445, the second output is transmitted. For instance, the fluid chord/character entry component 370 transmits the second output to the external device 120.
Finally, at step 450, the second output is displayed. For instance, the external device 120 displays the second output on the screen of the external device 120.
In the method 400, in a first example, the first data entry is the first character entry and the second data entry is the second chorded entry. In a second example, the first data entry is the first chorded entry and the second data entry is the second character entry. Thus, the data entry devices 110, 200 may perform fluid chord/character entry. The data entry devices 110, 200 may perform the method 400 continuously and thus continue to alternate between character entry and chorded entry.
In a third example, the first data entry is the first character entry and the second data entry is the second character entry. In a fourth example, the first data entry is the first chorded entry and the second data entry is the second chorded entry. Thus, the data entry devices 110, 200 may also perform traditional character entry or chorded entry, though the data entry devices 110, 200 do so by first making a determination to perform character entry or chorded entry.
In a fifth example, the first character entry and the second character entry are any letters of an alphabet, for instance the Latin alphabet, while the first chorded entry and the second chorded entry are any syllables, words, or phrases containing letters of the alphabet. In a sixth example, the first data entry or the second data entry is a command that may not be displayed. In a seventh example, the first data entry or the second data entry is a cursor movement that may be displayed.
In
At decision 505, it is determined whether spurring is active. For instance, the fluid chord/character entry component 370 determines whether spurring is active. The user may select whether to make spurring active. Spurring modifies recognition of chords during fluid chord/character entry. Specifically, to output a chord without spurring active, the user activates two or more keys 220 within a first threshold time and then deactivates those same keys 220 within a second threshold time. Fluid chord/character entry without spurring may result in false chords if the user types too fast. In contrast, to output a chord with spurring active, the user activates two or more keys 220 within a third threshold time and then may deactivate only one of those keys 220. The first threshold time, the second threshold time, and the third threshold time may be the same or different. If the answer to decision 505 is no, then the method 500 proceeds to decision 507. If the answer to decision 505 is yes, then the method 500 proceeds to decision 540 in
At decision 507, it is determined whether a number of current keys activated is greater than a number of last keys activated. For instance, if a user activates a first key 220 and maintains that activation while activating a second key 220, then the answer to decision 507 is yes. If a user activates the first key 220, then deactivates the first key 220, and then activates the second key 220, then the answer to decision 507 is no. If the answer to decision 507 is yes, then the method 500 proceeds to step 510. If the answer to decision 507 is no, then the method 500 proceeds to decision 520.
At step 510, a character is outputted. For instance, the fluid chord/character entry component 370 transmits the character to the external device 120, and the external device 120 displays the character on the screen of the external device 120.
At decision 513, it is determined whether a time from a last key activation is less than a threshold. For instance, the fluid chord/character entry component 370 determines whether a time from a last key 220 activation to the state change at decision 503 is less than a threshold. The threshold may be about 18 ms.
If the answer to decision 513 is no, then the method 500 proceeds to step 515. If the answer to decision 513 is yes, then the method proceeds to step 517.
At step 515, null is outputted and the method 500 returns to decision 503.
At step 517, a temporary chord output is selected and activated, and the method 500 returns to decision 503. For instance, the fluid chord/character entry component 370 transmits the chord to the external device 120, and the external device 120 displays the chord on the screen of the external device 120.
At decision 520, it is determined whether a chord is activated. For instance, the fluid chord/character entry component 370 determines whether two or more keys 220 are activated. If the answer to decision 520 is no, then the method 500 proceeds to step 523. If the answer to decision 520 is yes, then the method 500 proceeds to decision 525.
At step 523, null is outputted and the method 500 returns to decision 503.
At decision 525, it is determined whether a release speed is less than a threshold. For instance, the fluid chord/character entry component 370 determines whether a release speed of the current key 220 being activated is less than a threshold. The threshold may be about 18 ms. If the answer to decision 525 is no, then the method 500 proceeds to step 527. If the answer to decision 525 is yes, then the method 500 proceeds to step 530.
At step 527, null is outputted and the method 500 returns to decision 503.
At step 530, a context is applied. For instance, the fluid chord/character entry component 370 may select one chord in one context or a different chord in a different context. The context may include surrounding text. As a simple example, while the word “knowledge” can be chorded in a single data entry, or stroke, it can also be chorded in two strokes by following the chord “know’” with the chord “ledge.” Rather than selecting “know ledge,” the fluid chord/character entry component 370 automatically selects “knowledge” because the fluid chord/character entry component 370 knows that the chords “know” and “ledge” should form “knowledge.” Suffixes, prefixes, and other chord modifiers are also applied at this stage.
At step 533, characters are replaced with a final chord. For instance, if the fluid chord/character entry component 370 previously outputted characters and then selects a final chord, then the fluid chord/character entry component 370 replaces those characters with the final chord.
At step 535, the final chord is baked and the method 500 returns to decision 503. Baking is the process of freezing and recording a result of a computing process.
In
At step 543, a current chord is erased. For instance, the fluid chord/character entry component 370 instructs the display of the external device 120 to remove a current chord.
At step 547, a context is applied. Step 547 is similar to step 530.
At step 550, a current chord is replaced with a final chord and the method 500 returns to decision 503. For instance, if the fluid chord/character entry component 370 previously outputted a temporary chord and then selects a final chord, then the fluid chord/character entry component 370 replaces that temporary chord with the final chord.
At step 545, a final chord is baked and the method 500 returns to decision 503. Before baking, the fluid chord/character entry component 370 stores a value so that the user can backspace entire words or sentences with future chords.
However, unlike the casing 210, which is a single piece, the casings 620, 650 are two pieces. The casing 620 is part of a left-hand device 610, and the casing 650 is part of a right-hand device 640. Having both the left-hand device 610 and the right-hand device 640 provides improved comfort and portability. The casing 620 may contour to the shape of a left hand, and the casing 650 may contour to the shape of a right hand.
Each of the left-hand device 610 and the right-hand device 640 receives data entries and transmits outputs based on those data entries as described above. In addition, the left-hand device 610 and the right-hand device 640 work together to receive data entries and transmit outputs based on those data entries as described above. The data entries may be any combination of character entries and chorded entries. The character entries may be any character entries such as letters, including both vowels and consonants. The chorded entries may be any chorded entries such as syllables, words, phrases, macros, or sequences. In a first example, simultaneous activation of a first key 630 in the left-hand device 610 and a second key 660 in the right-hand device 640 results in a chorded entry. In a second example, simultaneous activation of a first key 630 and a second key 630 in the left-hand device 610 results in a chorded entry. In a third example, sequential activation of a first key 630 in the left-hand device 610 and a second key 660 in the right-hand device 640 results in a first character entry and a second character entry.
In addition, there is a dedicated key 630, 660 for each finger and thumb of the user. Specifically, a first key 630 provides dedicated data entry for a left-hand thumb, a second key 630 provides dedicated data entry for a first left-hand finger, a third key 630 provides dedicated data entry for a second left-hand finger, a fourth key 630 provides dedicated data entry for a third left-hand finger, a fifth key 630 provides dedicated data entry for a fourth left-hand finger, a sixth key 660 provides dedicated data entry for a right-hand thumb, a seventh key 660 provides dedicated data entry for a first right-hand finger, an eighth key 660 provides dedicated data entry for a second right-hand finger, a ninth key 660 provides dedicated data entry for a third right-hand finger, and a tenth key 660 provides dedicated data entry for a fourth right-hand finger. Thus, the user need not break contact with the keys 630, 660 in order to continue entering data. Thumbs have significant dexterity, particularly when compared to fingers, yet are used only for the spacebar in traditional keyboards. However, the keys 630, 660 dedicated to the thumbs are the same as the keys 630, 660 dedicated to the fingers. Thus, the thumbs are not limited to a single data entry like the spacebar, but may instead enter as much data as the fingers.
The remaining keys 630, 660 that are not dedicated to fingers or thumbs may output alternative data entries. Those data entries may be lesser-used data entries. In one example, the keys 630, 660 dedicated to the fingers and thumbs output data entries such as letters and other operations found on a traditional keyboard, while the remaining keys 630, 660 output other data entries or mouse control.
Furthermore, unlike the data entry device 200, the data entry device 600 may not comprise the cords 230 and the communications bus 240. Instead, the data entry device 600 wirelessly communicates with an external device using Bluetooth or another technique.
Together, the stem 720 and the key 730 move in multiple directions, including to the left of the page, to the back of the page, to the right of the page, to the front of the page, and to the bottom of the page. Movement to the left of the page corresponds to a left movement, movement to the back of the page corresponds to a top movement, movement to the right of the page corresponds to a right movement, movement to the front of the page corresponds to a down movement, and movement to the bottom of the page corresponds to a depression. Movement to the left of the page and the right of the page is in a first dimension, movement to the back of the page and the front of the page is in a second dimension, and movement to the bottom of the page is in a third dimension. Thus, the key 730 is 3D and provides 1D, 2D, and 3D data entry. Though five directions are described, the key 730 may move in more directions, for instance 8 directions, to provide additional alternative data entries.
The library 380 may comprise default key mappings. In addition, a user may modify the library 380 to comprise custom key mappings. Furthermore, the user may modify the library 380 to comprise custom macros, hotkeys, or hot words, which may function while only specific software is running. The number of possible data entries is essentially limitless.
The keys 805-830 are oriented about 0° with respect to the top of the page, so the keys 805-830 output data entries located above the keys 805-890 in response to up movements; data entries below the keys 805-890 in response to down movements; data entries to the left of the keys 805-890 in response to left movements; data entries to the right of the keys 805-890 in response to right movements; and, if present, data entries on the keys 805-890 in response to depressions. The key 805 outputs an “alt” data entry in response to an up movement, a “mirror shift” data entry in response to a down movement, a “# shift” data entry in response to a left movement, and a “shift” data entry in response to a right movement. The “# shift” data entry shifts the keys 220, 630, 660 to a “# shift” key mapping in ” data entry in response to a left movement, an “r” data entry in response to a right movement, and a “click” data entry in response to a depression. The “←” data entry corresponds to a backspace operation. The “
” data entry corresponds to a spacebar operation.
The keys 835-845 are oriented about 45° counterclockwise with respect to the top of the page, so the keys 835-845 output data entries located at about 315° in response to up movements; data entries located at about 135° in response to down movements; data entries located at about 225° in response to left movements; data entries located at about 45° in response to right movements; and, if present, data entries on the keys 835-845 in response to depressions. The key 835 outputs a “win” data entry in response to an up movement, an “RC” data entry in response to a down movement, an “esc” data entry in response to a left movement, and a “-” data entry in response to a right movement. The “win” data entry opens a start menu in a computer operating a Windows operating system.

At step 1010, a movement of a key is detected. For instance, the fluid chord/character entry component 370 detects that the stem 720 has physically touched at least one of the bottom contacts 740 or the side contacts 750.
At step 1020, a determination whether the movement is a left movement, an up movement, a right movement, a down movement, or a depression is made. For instance, the fluid chord/character entry component 370 determines whether the stem 720 has physically touched a side contact 750 on the left side of the page in
Finally, at step 1030, a data entry is selected based on the first determination. The data entry may be the first data entry in step 405 or the second data entry in step 430, and the data entry may be a text entry. As an example, the movement is an up movement of the key 880 in the default key mapping 800, so the fluid chord/character entry component 370 selects “h” as the data entry.
A user may activate a key 220, 630, 660 or a set of keys 220, 630, 660 in order to enable ambidextrous throwover. Ambidextrous throwover allows the user to enter all data from either the left side of the data entry device 200 or the right side of the data entry device 200 or to enter all data from either the left-hand device 610 or the right-hand device 640. Ambidextrous throwover therefore permits the user to multitask by entering data with one hand and performing another task, such as drinking coffee, with another hand. When the user desires to disable ambidextrous throwover and therefore use both hands for data entry, the user may activate the same key 220, 630, 660 or set of keys 220, 630, 660.
Movement of the keys 220, 630, 660, for instance the keys 815, 865, 915, 980, may control a cursor on the external device 120. For instance, a left movement of the keys 220, 630, 660 moves the cursor to the left; an up movement of the keys 220, 630, 660 moves the cursor up; a right movement of the keys 220, 630, 660 moves the cursor to the right; and a down movement of the keys 220, 630, 660 moves the cursor down. Thus, in addition to functioning as a keyboard or a stenotype, the data entry devices 110, 200, 600 may also function as a mouse. Providing both functionalities in the single data entry device 110, 200, 600 improves portability so that a user can plug in and play the data entry device 110, 200, 600 anywhere.
