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.
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.
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.
