Thank you for considering the Safe XO use page. See the Talk:Safe XO use page for more of my thoughts and intentions. You may see that the task of communicating health, safety, or security information requires a subtle balance to integrate with more attractive content in order to avoid rejection. Often, we only intend to plant a seed idea that will begin to grow at a later time, but hopefully before an incident, so those involved will have some reference or guidance points.
I like your idea for reminder software in some activities. I like the format of the Desk-Trainer software, http://www.desk-trainer.com/. It is an example of how computer graphics can be used to assist in physical and health education. --FGrose 04:02, 5 February 2008 (EST)- It's really unfortunate that the XO has such bad ergonomics. Perhaps with proper input the Write activity could be given a RSI forced break for X seconds every Y minutes. Maybe a window with a suggested exercise for one's hands? I've seen similar programs. And teaching children basic stretches and ergonomics could go a long way.

Ergonomics/safety
We should plan to familiarize the ergonomics community with the OLPC project through professional societies and other associational contacts. The Western New York Human Factors and Ergonomics Society local section is planning a walk-in workshop at the Rochester Institute of Technology this spring. Posts in the Ergoweb Forum, OLPC, an education project, and a fledgling scientific distribution site, SciVee, direct interested parties to the OLPC wiki and the Health section. There are already several public health and human factors students involved in the project and many more interested.
Analysis of musculoskeletal disorders and their causes generally involves understanding the postures, forces, repetitions (frequencies, durations, and patterns) of movements and of recovery times or the complementary movements during rest periods that provide physiological relief to the tissues involved.
Repetitive strain and other overuse health problems are also very much affected by the age and physiological conditions of the tissues involved, and may also be affected by environmental stressors. On top of that, individual, interpersonal, group, and organizational behaviors are known to play important roles in the progression and recovery from musculoskeletal disorders. All this makes it a complex and easily convoluted problem.
We have learned a great deal from experience with adults, but published knowledge about children's susceptibilities and capacities is more limited. A recently published textbook, Ergonomics for Children, Designing products and places for toddlers to teens, Edited by Rani Lueder and Valerie Berg Rice [ Taylor & Francis 2008 ISBN 978-0-415-30474-0] is a reference I would recommend.
Those interested may also want to read articles such as this one just published, Children's Posture and Muscle Activity at Different Computer Display Heights and During Paper Information Technology Use, by Leon Straker, Robin Burgess-Limerick, Clare Pollock, Jemma Coleman, Rachel Skoss, and Barbara Maslen, Human Factors: The Journal of the Human Factors and Ergonomics Society, Volume 50, Number 1, February 2008 , pp. 49-61(13). (It should be available in a medical or engineering library near you.)
I found it interesting to see that some of the Mongolian children had their new XOs set up on the shipping box, which seems to help their back posture. The project's photos and video could be mined for other postures and behaviors as revealed in these photos by Carla Gomez Monroy, Learning Consultant, OLPC, 17 Jan 2008:
The idea of studying postures could prove valuable in building an observation set of the variables I noted above for further technical study. One should start by reading some research papers and identifying some professors or students currently working in biomechanics, work physiology, occupational or physical therapy, orthopedics, or any of the related fields.
From a software support point-of-view, one might be able to identify or coordinate some activity tracking software that could be used to collect quantitative information on the time patterns of various activities by individual users. There are some studies of this for adults, but there are no generally accepted exposure dosimetry standards in ergonomics. However, all the energy conservation work that is going into the XO hardware and software may lead to some really useful tools to begin to collect the raw data to support new discoveries for children's ergonomics.
We can continue to collect ideas and references on wiki pages as we work toward a critical mass of participation.
Thank you for your interest in the ergonomics of the XO.
- Looking forward, --FGrose 00:12, 14 February 2008 (EST)
- noticed you're one person behind the ergonomics project - would you mind filling me in on how that's going sometime? ergonomics is a special interest of mine (well, one of my many interests; my family has a history of carpal tunnel, I've gotten mild RSI before, and I'm hoping to run a project during the Health Jam or otherwise - or earlier, if possible (main limitation: my time and my access to components) - to test muscle strain and postural differences between various keyboards, "normal" laptops, and the XO for both kids and adults with different hand/finger/shoulder/etc. dimensions (and hopefully mobility, if we can find one-handed etc. typists). I know how to build test equipment, but almost nothing about how ergonomics tests are usually run, or ergonomics as a medial study proper.
- also, the students at Olin have equipment and know-how and the desire to run other safety tests on the XO (they'll be using impact testers, etc. in their materials science lab to check various physical qualities this coming weekend, including when dropping/smashing things might become a hazard) - I'll be there for the tests if you want to chime in on that as well. Contact info on my user page.

There is a wiki at Biomechanics Knowledge Repository that has a page on measuring techniques. The site has not been very active lately, but it has some good links. I'll poke around some more for open, online sources. --FGrose 02:31, 14 February 2008 (EST)
Here is a link to the International Ergonomics Association's Ergonomics for Children in Educational Environments Technical Committee's home page. They have a Research page with links to many accessible papers. --FGrose 20:16, 14 February 2008 (EST)- Thanks. All the resources you linked were to articles and books you need to purchase, though - do you have any pointers for good free resources or papers on ergonomics testing and testing equipment/software? (Beyond the usual "search google and wikipedia for whatever terms you know," of course - I'll do that, but you probably know how to hone in on the good stuff faster.)
