Thanks for taking the time to write, and also for pointing out a place where my writing could be improved in order to better reflect my intent. I will certainly update the passage to reduce the chance of what I was saying being misinterpreted.
The key word in the first sentence that the reader seems to have not paid enough attention to is the word "generally". In the second sentence I gave an example. But, of course, it is not the only example, nor a general one. Using gestures on a touch screen to operate an MP3 player increases the risk of an accident, compared to other options (one of which is speech), even if one is using gestures. Furthermore, the person making the statement makes an incorrect assumption that my statement indicates that I had not thought about, or did not take into consideration, the use of gestures on a touch screen or touch pad, much less the distinction between the use of gestures on a touch screen/pad, compared to touch key-presses.
I just did not go into that example at this location. That is not the same thing as teaching/advocating any lack of knowledge. My work with touch devices for music performance in the late 1970s and in the 1980s very much made use of gestures. Furthermore, I was shipping a product, Alias|Wavefront's Portfolio Wall, in 2000 (i.e., 9 years before Flicktunes) which may have been the first commercial product to use lateral finger-swipes (i.e., gestures) to transition forward and backward through a sequence of images or a slide-show, as well as using directional gestures to control video playback. The flicking through images with the original iPhone is direct reimplementation of what we were shipping 7 years earlier. There are 3 different videos, I believe, demonstrating the Portfolio Wall on my YouTube Channel (wasbuxton).
The challenge in writing about all of this is how to get the key points across in a short space, that is, without writing a book.
Anyhow, it is easy to address the issue at play here, and, if I look at it objectively, I can easily see how the person got the wrong impression, given how and what I wrote. This is easy to fix.
So, thanks a million for your help and note. I really appreciate it. And, the only reason to write something like that page is to try and capture, and share, some of what I have learned over the years with such systems. No point in all of us reinventing the wheel
Thanks again.
