I will examine this unfortunate side effect, Repetitive Strain Injury (RSI), of the Digital Age in this essay. It has probably affected someone you know. I hope this information will cause you to pause, look at your computer setup and initiate changes that make your computing safer and more comfortable. And if you've already experienced some of RSI's disabling and career-threatening effects, I hope that this article eases some of your anxieties by describing methods, approaches and treatments that have helped others.
Writers and editors in particular put in an awful lot of miles at the keyboard every day. One serious problem is the risk of so-called 'repetitive-stress injury' (RSI)--simplistically, any injury that results from overuse of a body part without giving it time to recover. In fact, 'overuse injury' is probably a more immediately obvious term, and given how much time many of us spend using computers, overuse is indeed a risk.
Writers and editors in particular put in an awful lot of miles at the keyboard every day. For example, I commonly spend a solid 8 hours typing. Writers and editors in particular put in an awful lot of miles at the keyboard every day. For example, I commonly spend a solid 8 hours typing. Then there's that darned mouse. W. Wayt Gibbs, writing in the June 2002 Scientific American, used the Mouse Odometer software (www.modometer.com) to monitor his habits and found that in a single 5-day period, he'd recorded 2440 feet of mouse movement and nearly 22 000 mouse clicks. It's no wonder computer users sometimes experience serious physical problems.It's no wonder computer users sometimes experience serious physical problems.
There is tremendous potential for developing mobile-based occupational productivity tools for semi-literate and illiterate users in India. One-handed thumb use on the touchscreen of smart phone or touch phone is considered as an effective alternative than the use of stylus or index finger, to free the other hand for supporting occupational activity. In this context, usability research and experimental tests are conducted to understand the role of fine motor control, usability of thumb as the tool for interaction and the ergonomic needs of users. The paper touches upon cultural, racial and anthropometric needs related with the topic, which also need due consideration while designing the mobile interface. Design recommendations are evolved to improve overall effectiveness of one-handed thumb use on smart phone, especially for the benefit of semi-literate and illiterate users.
