As it sounds, it is HALF of a normal keyboard. When the space bar is depressed, the missing characters are mapped onto the remaining keys in a mirror image, such that the typing hand makes movements. This is a very good option for adults, who are already knew a touch typing system before their disability. For more information, or to purchase this software, or the new Half Keyboard, click here. Voice recognition and wearable computers.
Voice recognition is available right now in almost all new computers.
Wearable computers are just around the corner for mainstream use. In another 20-30 years, my guess is we will all be working with some form of voice recognition wearable computer, very possible attached to our cell phones. However, someone will still be programming computers then, and being paid a great deal to do it. To fill the next 30 years with productivity, I suggest you learn to use the standard keyboard before you learn the alternatives. Just as we must learn to read, before we allow ourselves to enjoy 'books on tapes,' we must learn the standard keyboard before we use voice recognition.
