"Have you ever had to put back a game because you knew there was no way you could control the character?
" asks Steve Spohn, Editor-in-Chief of the AbleGamers website and Community Outreach Chair the AbleGamers foundation. As someone afflicted by spinal muscular dystrophy, a disease that slowly takes the ability to use muscles, he has. For Steve and the rest of his staff, accessibility matters. Matters so much that they evaluate games based on the degree to which they can be altered and adapted for a wide-variety of disabilities. An Able Gamer's Accessibility Review As someone who can only move a mouse about, "one inch in any direction," Steve has to dig deep to find games he can play: MMO RPGs and casual games are the most accessible, simply because they have the most ability to adapt to their customers and the lowest demand on quick movements with multiple keys.
Still, Steve finds plenty to play thanks to companies that go the extra mile. A Seat In History. Object Design. Best Sitting Posture. , seating position, or seat posture can make all the difference in comfort. For as long as I can remember, sitting straight up was considered the optimal position. Parents would preach it, doctors would suggest it. This just never made sense, because very few people really feel comfortable sitting straight up. Recent studies show that the optimal sitting posture is not straight up (90 degrees) but actually leaning back at roughly a 120-135 degree angle.
It shouldn’t come as a surprise, as this is arguably one of the most comfortable positions to sit. When strain is put on the spine, the spinal disks between each vertebrae will move or misalign in a minute way. Here are a few examples of chairs that can provide the proper amount of tilt for optimal sitting posture: So, the next time someone corrects your and asks you to “sit up straight” you can correct them and say “no, lay back at 135 degrees.” Tagged as: Ergonomics Related Posts Popular Sofa Buying Tips Chaise – A Chair for your Legs?
Posture Research. Is chronic back pain caused by the manner in which we sit?
For many people, this could be the case, according to a growing number of experts in the field of ergonomics. Add to this the fact that we are fast becoming an information processing society, in which increasing numbers of workers transact business while sitting for long periods of time, and we begin to see the crucial role that sitting may play. For modern researchers, many of the ideas proposed two decades ago by Danish surgeon, A.C. Mandal, M.D., regarding the spine began a major paradigm shift in the way we evaluate the seated worker. Many of these ideas have been validated in more recent studies. When standing erect, the spine assumes a posture of natural lordosis, while kyphosis is difficult to avoid in traditional seated postures. Some of the known negative effects of traditional, 90° sitting include: Mandal emphasized a way of sitting where posture approached the spine’s natural resting position.
