I see things differently. It is a topic which I am very interested in.
I have been interested in language and writing for many years. I used to read cyrillic, chinese and even ancient egyptian hieroglyphs.
Worldwide and since the beginning of history, written language is nothing more than transcribed speech - each character is a sound (not a picture - contrary to popular belief).
Many people think that we now use the alphabet to write and assume that it is something etched in stone, which will certainly not be the case. What will follow?. Many university researchers are working on this and we have no clue. Certainly not audio or video ! If you polled researchers today, most would bet on something which vaguely and distantly looks like a tibetan mandala which you would read like a text (nothing to do with religion).
Look for example at how the language of mathematics is changing, and looks like drawings of insects.
excerpt from the recent article below:
Something strange is happening in mathematics seminar rooms around the world. Words and phrases such as spider, birdtrack, amoeba, sandpile, and octopus decomposition are being heard. Drawings that resemble prehistoric petroglyphs or ancient Chinese calligraphy are being seen, and are being manipulated like the traditional numerals and symbols of algebra. It is a language that would have been alien to mathematicians of past centuries
Why am I saying this? Because we should also expect dramatic changes in the way we input information into computers. I used to laugh at the idea of using a mouse, and immediately caught on to the idea of a trackpad. In the same vein, typing at a keyboard makes absolutely no sense. I can just imagine a keyboard displayed in a museum in the future. For the moment, the only 'progress' is the trackpad, and I want to take full advantage of it, and that was the idea behind using the power of KBM to trigger BTT gestures.
What boggles the mind, is that you basically have only one decent trackpad app (BTT) which is just a hobby for anotherwise busy Siemens software developer whose work has nothing to do with trackpads.
Historically, we know that new inventions existed and were often ridiculed long long before they became mainstream. Quantum mechanics was developed in (I think) the 1930's, and Einstein himself said it was ridiculous ('God does not play dice'). I am convinced that the next computer input method exists today (probably discussed all over the Internet), and is being ignored or ridiculed. It's only a question of time before keyboards are a joke. That's why I think that @peternlewis should seize the opportunity and find a way implement gestures ASAP.
