This is true, but I'm not sure it's relevant in this case. AFAIK old people generally have more trouble controlling how far they push things, but the only distinction we're interested in here is whether they're pushing or merely resting their hand. This still wouldn't be enough for people with diseases that cause major tremors, but I'd imagine it's enough for people who have lost fine motor control, because we're only trying to distinguish pushing from not-pushing.

Nope. The older you get the less mechanoreceptors are left in your skin. This has 2 effects then: You actually do feel less pressure or vibration from touching something and You can't control your fingers as well because the feedback system has less input for fine motor control into the cerebellum. You cannot feel nor control as well. Additionally, human touch sensation is incredibly good in the fingers, hypothesized to be related to our use of tools. That we can at all use such a touch screen is a miracle in the animal kingdom. Replacing this is not possible at this point in time as we age. However, larger and more clear buttons will help, along with a training period and good motivation for the person. As we age, we need to have the motivation to access the world and the opportunity to do so. The future requires all participants of every age. A good place to start on the sources is here: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2563781/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2563781/ . Let me know if you want a .pdf and cannot access the site past the abstract.

    Excuse the pun, but HOLY BANANAS! That is amazing! Thank you for that vid and the info. That is so cool! I had no idea the chimp could be trained like that. Amazing! Thank you!

      Bonobos, a similar ape species equally related to humans, can actually play video games, drive golf carts, and all kinds of cool stuff. http://www.ted.com/talks/susan_savage_rumbaugh_on_apes_that_write http://www.ted.com/talks/susan_savage_rumbaugh_on_apes_that_...

    It would seem they also have far better short-term visual memory than typical humans. Or maybe that's the result of practice. Time to find out...

    Oh wow, this is amazing! Looks like it only need a split second to remember the positions of the number in sequence - Unbelievable!
