Typing with just one finger – Dasher

Dasher is a one finger user interface that allows text entry without a keyboard.

Keyboards are inefficient for two reasons: they do not exploit the redundancy in normal … all » language; and they waste the fine analogue capabilities of the user’s motor system (fingers and eyes, for example). I describe a system intended to rectify both these inefficiencies. Dasher is a text-entry system in which a language model plays an integral role, and it’s driven by continuous gestures. Users can achieve single-finger writing speeds of 35 words per minute and hands-free writing speeds of 25 words per minute. Dasher is free software, and it works in all languages, and on many platforms. Dasher is part of Debian, and there’s even a little java version for your web-browser.

Dasher Demonstration

Honestly, I pretty much disagree with this method being more efficient than keyboards. The reason you type fast is because your fingers are used to the words you are typing, that is to say you typed the word before. However I see a possibility how this new method could benefit physically impaired users.

Chinese joke on computer peripherals

I found this random bit in one of my text files in the computer:


荧幕说:我好惨啊… 每天给人看。
Mother Board说:不要以为我被很多东西插会很爽,它们插进来后就都不动了,那才是难受啊。

Bought the same old keyboard

Not sure if you noticed how little I blogged last week. My previous keyboard was all to blame. The alphabet ‘e’ cannot work and no matter how hard I depress it, the cursor just blinks nonchalantly.

Since ‘e’ is the most common alphabet in daily English, I was type-impaired. Assigned the alphabet ‘e’ to Control+C works for 5 minutes but I given up typing soon after.

As a bonus, I never did as much studying for a week. Perhaps when examination nears I can consider wreaking my keyboard.

Anyhow, I bought a new keyboard. It’s the very same one from Microsoft. It’s the wired curve keyboard 2000 or something. I got so used to it I couldn’t feel right typing on something else.

Your keyboard may be dirtier than a toilet seat

This makes me feel like cleaning my keyboard on a Saturday afternoon:

Your computer keyboard is FIVE TIMES dirtier than your toilet seat

Computer keyboards can harbour more harmful bacteria than a lavatory seat, it has been claimed.
Many users are at risk of becoming ill with stomach bugs, according to the consumer group Which?

One keyboard was so dirty that a microbiologist ordered it to be removed, quarantined and cleaned. It had 150 times the acceptable limit for bacteria and was five times as filthy as a typical lavatory seat.

Anyone who eats a sandwich or piece of fruit having been tapping on such a keyboard can pick up bacteria that could lead to a stomach upset.

The scientist swabbed 33 keyboards for food poisoning bugs e.coli, coliforms, staphylococcus aureus and enterobacteria and compared the results to those found on a lavatory seat and lavatory door handle. (Source: DailyMail)

But I supposed this may be true. Even toilet seats are cleaned regularly in my house. My keyboard is cleaned like once in a blue moon. Argh… Okay, I’ll clean it today.


Above is my keyboard. Quite dusty it turns out.
