These kind of keyboards are particularly useful for people who type by randomly smashing their hand / head, foot etc against the keyboard, of course: you really need to catch *all* the keys you hit for the proper effect.

For example, Wikipedia cited Braille2000 http://www.braille2000.com/brl2000/KeyboardReq.htm quote: To use any computer braille-entry program, including Braille2000, you will need a keyboard that responds to six-key input. Be alerted that many famous-brand computer systems are supplied with keyboards that are NOT suitable. Be especially careful when shopping for a laptop computer�not being able to use its built-in keyboard will be a real hassle. didn't actually read this page before, but i will now. Quite interesting. ----------------------- but also, in gaming, the need to press more than 5 keys simultaneously is common. Usually, the arrows keys or wasd keys are control your character movement, while Shift down with left/right arrow makes your avatar move left/right instead of turning left/right. Sometimes 2 arrows such as up/right arrow makes your avatar walk diagnoallly. Add in jump or squatting key, usually needed to be combined with avatar movement keys. Add the fact of run mode, usually can be a modifier. Then, there's also things like firing, shield, quickly you have 5 or 6 keys pressed simultaneously. modern keyboards already have shifted their electronic grid so that multip key combo with the modifier is no problem. But when the game or game playing gets advanced, like doing some strife shooting while prim jump etc as in Second Life, you need a keyboard that does well. For this reason, as cited by Microsoft and elsewhere, gaming keyboards often take the extra mile to make this correct. but as another example, i recall about 10 year ago, i can play Street Fighter on PC or other similar game on the Mac, in a 2 player versus mode. For single player you need 6 or so keys. For 2 person playing on the same keyboard you really need keyboard that can detect some 20 simultaneous keys correctly. Imagine all the super combo keystroke to get special attacks. LOL Xah â http://xahlee.org/ â

I think the Braille example is good as it's (I assume) a small proportion of users who might therefore not be well-served by the market. But the gaming example I think must be spurious: quite a lot of people play video games, I think. So I'd expect that keyboard makers who make keyboards which are not suitable for playing games on would suffer quite badly.

Some limitations are by design, that is: when a feature is not likely to be used, it's cutted off, making production cheaper. In this case, it happens to a key combo. |
