Abstract

알파 로움 텍스트(Alpha Roam Text) 골라긋기(Swipe) 입력 자판의 문자 배열 및 입력 과정은 아래와 같다.눈의 피로를 줄이기 위해 자유 왕래 바탕 화면(Roam Display)을 검은 색으로하고, 21개 고 빈도 알파벳 키( 21- Most Frequent Alphabet key)는 흰색으로 배정하면서 타건(Tap)으로도 입력되고 긋기(Swipe)로도 입력되도록 고안했고, 자주 안 쓰는 5개 검은 색 알파벳(5-Least Frequent Alphabets)은 오직 전용 타건으로만 입력되지만, 손가락이나 스타일러스 펜이 5개 검은 색 알파벳을 스와이프 연결( Swipe Gesture )할때 자유 왕래해도 5 개 알파벳이 인식 안되게 고안 했다.
연이은 알파벳( Sequenced Multigraph)을 효율적으로 배열한 자판 위를 자유 왕래 하면서 원하는 알파벳만 연결하여 단어를 쉽게 조합 한다. 자유 왕래 화면을 활용하여 타건도 입력되고 골라긋기도 지원하는 복수 양동(陽動) 기능이 본원 제안 기술의 백미요 최대 압권이다. 간단하고 균형있는 문자 배열, 사용빈도, 연이은 자음고리를 원용하여, 골라긋기 입력을 극대화할 때 알파벳을 연결하는 동선(Gesture)의 학습 효과가 알파벳 자음, 모음의 위치를 쉽게 인지할 수 있게 한다. 그래서 알파 로움 텍스트의 입력 방법은 생체 리듬에
맞는 생명 공학적 최적화(Ergonomic Optimization) 자판 배열이다. 골라긋기 입력으로 연이은 자음고리( Multigraph)를 입력하면, 빠르고 간편하게 자음, 모음을 조합할 수 있다.
쪼개긋기를 지원하므로써 방대한 기존 프로그람의 단점을 보완 했다. 또한 골라긋기 입력은 쉽고, 빠르고, 정확하다.

Description

알파 로움 텍스트{Alpha Roam Text}

This proposal is an Alphabet layout for the mobile device

The proposed touch screen keypad consists of dark Roam Space, 21-white Tap or Slide keys and 5 dark Tap Only keys;

Keypads are widely used in various electronic devices, such as personal digital assistants (PDAs), multi-purpose cellular phones (3G phones) and Smartphones, to enter alphanumeric inputs and/or commands. In a typical keypad, the keys are usually arranged in a QWERTY configuration or a 12-key configuration, which is commonly found in cellular phones.

A concern with the QWERTY configuration is that the locations of the keys are not efficiently arranged. Thus, a user has to learn where the key are located in the QWERTY configuration in order to enter different words. Furthermore, since there are twenty-six different keys for the different letters, learning where the different letter keys are located can be challenging.

Similarly, a concern with the conventional 12-key configuration is that the keys are not arranged in an efficient manner for entering words. Although the keys for the different letters in the conventional 12-key configuration can be readily found, entering words using these letter keys can be difficult since three or four letters are entered using the same key. Furthermore, there is no correlation between the locations of the letter keys in the conventional 12-key configuration and words that are typically entered. Thus, entering words using such a keypad　can be difficult.

In general, a diagonally arranged 26 key-QWERTY layout is hard to Swipe in a narrow Touch space, and even worse, may typos. or pick the correct word among the unwanted predictive words lists. It is just time consuming.

With QWERTY swipe program, you cannot input Proper words such as Arirang, Danawa, Naver, Daum, er, ine not to enter the number (see Table 1)

When you Slide(Swipe) [from "A" to "L" ] unwanted (All, Ask, Skip, Alp, Slip) will show up.

Sliding [from "Q" to "P" ], (Quit, Equip, Quiz, Quito) will pop up.

When you Slide [Z to M], (Xml, Xmas, X-men) will be displayed..

General 26 Qwerty Swipe flicking, it did not support the flick split (again broke in the middle ear flicks) because they can not complete the English word you want is a flick input and being outside, flicking input instead of input velocity is alive and well as a trend.

The arrangement of keys of the Alpha Roam Text　keypads　100 are　 designed pedagogically and in accordance with principles of dynamic programming to achieve optimal ease of learning and ease of use within a line movement of the stylus pen /finger of an operator.

Steep Learning Curve and Muscle Memory Struggle

If you are touch typing on a QWERTY keyboard, you are making use of muscle memory, which increases your speed. Switching over to a Dvorak keyboard, for instance, will feel awkward and you will have to search for the keys at first. However, some users claim that the Dvorak has a shorter learning curve than the QWERTY if you are learning to type from scratch. The Colemark was designed to be more efficient than the QWERTY, but with a short learning curve if you are switching over from QWERTY to Colemark, as the locations of only 17 keys were changed. If you decide to switch over to another layout, you might struggle to type QWERTY again, and will end up frustrated when trying to work at other people's computers.

Property of Qwerty Swipe

Speed and Accuracy

There are other layouts that claim to be more efficient than the QWERTY, allowing for higher typing speeds. QWERTY places letters that are rarely used in the most optimal positions, while your fingers need to stretch for the keys you use all the time. Words with long sequences need to be typed with the same hand, and it often jumps from the home row, slowing down your typing. Dvorak and Colemark keyboards were designed to correct this problem, and to have letters alternate better. For instance, it is a common mistake to type "teh" or "hte" on a QWERTY keyboard instead of "the," because the keys alternate badly and you have to type outward rather than inward. Making mistakes slows down your typing, as you have to go back and correct your work all the time.

Non-ergonomics

The QWERTY keyboard was not designed to be ergonomic. It has a high same-finger ratio, which increases strain. If you type constantly on the QWERTY keyboard, your chances of developing carpal tunnel syndrome are higher than with a more ergonomic layout. The distance you have to cover to stretch for certain keys is also higher than on the Dvorak, causing more strain to your hand.

Slower typing speeds

Predictive Word Program is a massive waste of memory under Qwerty Swipe input

Qwerty Swipe can not input the most commonly used proper nouns or multi-graph letters.

When you break the gesture motion, it stops.

Inputting proper nouns or even a good random characters make program stop.

To optimize the alphabet Swipe Input.

Build matrix layout with more rows and fewer columns

Support the continuous Swipe Input,

More specifically the proposed Alpha Roam Text accommodates;

1. 5x5 matrix with 21 Frequent Alphabet keys.

2. High frequency alphabets are arranged around 5 vowels

3. Utilizing the continuous swipe program, connect correct characters

To summarize again, this proposal is to achieve the optimization of swipe motion, so we can choose the alphabet key 21. The proposed Alpha Roam Text Swipe is designed to continuously pick and choose the correct characters. In case, swipe motion breaks down, Roam Text Swipe completes the mission.

흰 알파벳 키를 설명하기 위한 배치도이다. 핵심 21개 다 빈도 알파벳 키는 타건으로 에디터화면(Editor)에 입력 한다. 원하는 글자를 골라서 입력할 수 있는 기능이 본 로움 자판의 핵심이다

In the Alpha1text keypad 100, the most frequent single letter “E” among the twenty-six letters of the English alphabet is positioned near the bottom of the center of the core 5x5 key matrix 102, and thus near the focal point of the core 5x5 key matrix . The other four vowels, “I”, “O”, “U” and “A” are positioned near the letter “E”. Specifically, the “I” key is positioned on the center column, two steps above the “E” key. The “O” key and “U” key are positioned next to the “I” key on the right in a row. The “A” key is positioned right below from the “I” key. The sixteen most-frequent consonants, “D”, “H”, “L”, “N”, “R”, “S”, “T”, “W”, “K”, “C”, “M”, “P”, “F”, “B“ “Y” and “G” are arranged around the vowels in relation to letter frequency and Roaming space tendency. The five less-frequent Tap only input consonants, “J”, “Q”, “V”, “X” and “Z”, are displaced to the dark Roaming Space. All the vowels and consonants are arranged in line with letter-frequency of use and digraph tendency and operated by a minimum movement radius of the operator. Thus, the Alpha Roam Text keypad 100 has a unique cluster arrangement of keys that is both schematic and ergonomic to improved learning ability and ease of use

The principle of the learning curve for a keypad requires an optimized letter-frequency along with digraph layout that facilitates text entry. The Alpha Roam Text keypad 100 is configured such that the most commonly used 21 characters including all 5 vowels are in line with a digraph tendency that accounts for 97% frequency in any input-text. This schematic layout makes the key area more interrelated and compact. This has a number of advantages:

?

o 1. An overall reduction in the finger/stylus distance.

o 2. Friendly interface of keystrokes

o 3. Optimum use of digraphs, trigraphs, and strings of letters (characters), etc.

o 4. Since users are already familiar with the configuration of 12-key keypad, the layout of the Alpha Roam Text keypad100 improves usability/flexibility, which means that the layout of the keys can be learned very quickly, i.e., fast learning curve.

o 5. Character arrangement in a cluster according to letter frequency of use creates a user-friendly interface.
