Numpad-QWERTY, One Hand Typing Using Standard Keyboard

Free Software for Your Productivity and Convenience

Ever getting tired of switching your hand to and from the mouse? Ever wondering how to type fast and leisurely with a single hand, while use another hand to hold a cup of coffee? 

  • You may have already known there are some expensive hardwares for one hand typing, such as half-qwerty keyboard and Frogpad.
  • There are also free software ones, such as the sing-hand AHK script available from the AutoHotkey forum. But you may not like to freqently press “Space bar” as this largely slows down the speed. Moreover if you type fast without switch off “Spacebar mode”, there are some interferences.
  • There are also some single hand keyboard layouts exist, such as “one hand Dvorak“, “Left hand Ngaih” and “ENTI“. However switching the keyboard layout in a daily usage is really troublesome. No to say learning a new keyboard layout can often be a disaster for most people.
  • Another approach is to use f, g, h and j as home positions, but it needs long range hand movements and hence a long time to master. You may also feel tired soon since the exercise is too intensive.

Let’s see what people talk about learning a different keyboard layout, e.g. Dvorak 1 2 . So most of us are not satisfied with existing methods.  Moreover, most of them can not be easily customerized and the typing speed is limited.  Indeed some people only use single-hand typing for 30~40% of their time, and it is preferable that single hand typing and two hand typing can co-exist without switching. A novel free tool based on the principle of “Chorded Keyboard” is then presented here.  Let’s find more …

Introduction

Free Software for Your Productivity and Convenience

Welcome! Here I will showcase several tools developed by myself!

  1. Numpad-QWERTY - a “One-handed Typing App” which can co-exists with ordinary two-handed typing seamlessly and can be easily switched on/off. Better than most existing Half-QWERTY methods.
  2. Taggie-and-Tagging  -  a “File Tagging App” for editing keywords tags of pdf/word/mht files within individual file browsers (e.g. Acrobat/PdfXCV) and  a “Tag searching App” for searching tags added by Taggie,  do search during typing like the ‘Everything Searcher’
  3. ASDF-QWERTY – another  ”One-handed Typing App” which can co-exists with ordinary two-handed typing seamlessly and can be easily switched on/off. More natural than Numpad-QWERTY, under development.
  4. Many other tools for improving productivity. Information available via personal contact.

ASDF-QWERTY, more natural for one hand typing

In principle, we can remap the character keys to other functional keys, for example w <->Numpad7, e<->Numpad8, etc when the keyboard has a numpad, or q <->F1, w <-> F2 when the keyboard doesn’s have a numpad.

So we can put our hand on the default home position, that is ASDF.

With a suitable keyboard remapping and a suitable key-hooking application (e.g. ASDF-QWERTY), we can combine the benefits of corded keyboard and standard keyboard. Moreover this approach can be used for Laptop Notebooks. Of course, it is also much easier to be configured for right hand users.

The key-hooking can be also done by means of a windows driver, so you simply press a key (e.g. ScrollLock, which is not often used) to toggle the keyboard layout. This can be done by adding a new keyboard layout with modified kbdus.dll and registry info. You may install a IME for that layout.

If  anyone wants the program, please leave a comment.

Introduction to One Hand Typing

A General View

The idea of one hand typing is to only use one hand (e.g. the left one) and type typical the other hand (e.g. right-hand) letters. Its history and application are closely related to keyboard research on QWERTY and Dvorak Simplified Keyboard.

Type with one hand can be done in a number of ways, and novel approaches are still emerging. People handle this situation in different ways and the solution depends on whether it’s a temporary condition, as well as the pupil’s physical abilities, muscle strength, cognition and memory, etc. Therefore existing approaches may fit different expectations.  We will focus on approaches using standard 101/102 PC keyboards here.

One hand typing while another hand holding a cup of coffee” is sometimes desirable by many typist. However, often one-handed keyboard typing for a long time is rather slow and as only one hand is being used it can also be quite tiring. With the latest Numpad-QWERTY, you may find the best compromise. Continue reading

Taggie-and-Tagging

Free Software for Your Productivity and Convenience

Taggie-and-Tagging is most suitable if you have a lot of pdf/mht/doc files to tag. You may want to add tags seamlessly and search the tags efficiently. However you can customize the tool for more usages.

  • You may have tried Tag2Find, TagTools, Tagged Frog.  But …, Only Tagged Frog is still progressing slowly.
  • Some may have tried Mendeley, Zotero, or WizFolio. But they are often too large for tagging purpose. They are normally so slow, and it is not so fun to have them run in the background.

Taggie-and-Tagging is quite like the fastest and light-weight “Everything filename searcher” and is therefore much better for professionals and academical researchers ……
