I noticed that my wrists have been hurting these last few days. My neck hurt as well.
I asked a long time ago what can be done for avoiding writing too much. This got me looking into and thinking about posture, writing, ergonomics, keyboards, typing, iOS.
I came upon the conclusion that I should try to bring about good in the world by drawing people's attention to note things they would otherwise not notice.
Note: there were several puns in the last sentence. Just drawing your attention to that.
So one thing that is stupidly unchanging, is chair design. Our chairs will always be built with the ideas of yesterday in mind. But I want to describe the general principles of a design so that an automated decision making processes can update our model in light of new data so that whatever is known at the time about the nature of human ergonomics and information representation tasks can easily be incorporated into the design. I want to design a chair for today.
Yes I know it's cheesy. Whatever it's catchy too! :p
I can't, no one can(yet) but I want to get as close as is possible. I would argue that since I have massive limitations in information processing en masse, if a computer can compute some of the relevant parameter updates, it will be more up to date than I could ever do on my own. This is simply a property of the fact that I can't read all the papers, and analyze & synthesize them as fast as others can produce them. Furthermore, even if I could keep up with it, I'm much more likely to be able to live a happy life if I don't have to do as much to keep it state of the art.
In any case I don't know what back angles would be good because I don't know what the dynamical and structural stresses that the relevant tissues face.
If apple really is going to make an hBook(i.e., the healthBook app), wouldn't it be awesome if it could automatically adjust your chair in response to whatever it is able to sense either from the chair or the lumoback(or lumolift) or smart wrist guards. Whatever it needs to it can automatically adjust to counteract any unhealthy behavior — if it really is the ideal chair with machine learning capabilities, it will be able to do that.
More on this later (esp. As relates to typewriters and keyboards).
Here are some desiderata for such a chair, which will act as potential learning/error signals if the chair for today were made real.
There are videos of me attempting the left handed curl, but I'm not very good at videotaping my writing. The ideal chair would fix that.
In any case avoid, painful hands. They are good for no one. If siracusa has taught me anything, it is that.
