Some of the most common devices people think of when it comes to input devices are the mouse and keyboard so I’m not going to use those as examples. One of the input devices I use regularly is a Multi-function Printer. I use the scanning feature of this device to upload documents on to the network. One of the nice things about it is that it offers different file formats to scan the documents as, my favorite one is .pdf and depending on the use searchable .pdf. It also allows me to either scan to a network drive or directly to my e-mail. Some other input devices I use are a Jabra USB headset for meetings which is really a combination of input through the mic and output via the earphones. I also use a Logitech webcam for meetings which is another input device.

As for output devices the most common I use are my monitors which I have 3 on my primary work system in spanned mode. My home system only has 2 monitors which I need to rectify. I also use my speakers and headset to output sound. Lastly my printers, at home I have a multifunction HP inkjet printer and a HP 4250 LaserJet printer. At work I print to a large Lexmark multifunction printer.

I read some interesting things about preventing injuries due to using computers. I think the best was just to make sure you take regular breaks and avoid using the same positions all day. One I had not heard about was to avoiding using the scroll wheel on a mouse if possible. I think one of my biggest challenges is my desk does not have sufficient room to support the end of my arm and wrists. I need to work on my arm position while typing and using a mouse. I do however think I stress my wrists more using my phone and tablet than I do using my desktop computers.

Input hardware I use is the standard, mouse and keyboard. Every so often I’ll use a microphone. The output devices I use are standard as well. I do have a dual-monitor setup, and use headphones usually for sound. One of the best ways to avoid eye stress is software called f.lux. It’s great because it dims the blue in the monitor to ease the stress on your eyes. Many different studies have shown that the effects of blue light from monitors have adverse effects on your wellbeing. The Harvard medicine journal entry I’ve attached goes over how it can make it harder to get to sleep and night and harder to have solid REM sleep, the blue essentially suppresses melatonin (Harvard Health Publications). F.lux softens blue light automatically for you depending on the time of the day and the projected sunset time for you area (F.lux). I also have a really nice bucket “race car” chair that has great lumbar support, it’s nice and tall as well which is great because I’m 6’3″ so I need a chair that is as tall as me or else I tend to slouch into the chair. I also like to rest my entire forearms on the table instead of just my wrists, helps with the wrist and ligament strain. At work I tend to get up about every 40 minutes or so and go get some water or just walk around and say hello to people around the office just to get away from sitting and starring at the monitor.
