Keyboard
Everyone who has computer or use computer have to use keyboard. it convert human pressure to the keys that had been programed to any alphabets to digital signal.
People use it in so many way. For Desktop computer, Mostly they have to buy separate keyboard. They came in to style, with cable and bluetooth. the way that they use is pull it close to body and make it more comfortable.
For someone who need portable computer always use keyboard that already attached in laptop.
From what i watched people use it without them knowing they’re being observed. I found that it make them be in not good position. Some people looks like uncomfortable be cause it can not pull down or move it close to themselves. Position of joint and wrist had been pressed.
I have seen some people who had laptop and bought separate cable keyboard to make it more comfortable and conveniently to use. even that laptop came with keyboard already. But mostly for people who don’t move that much.
my case is different, my friend spilled water on my keyboard and it broke so i have to buy a new bluetooth one and bring it everywhere. for some reason i found out that it pretty useful like this picture.
i can move it close to me everywhere even lay down and type. only bad thing is i can’t see the monitor because my eyes problem.
another keyboard that i just got so far is mobile projection keyboard with bluetooth.
I rarely use it because i don’t like the feeling of didn’t press something but just touch it. it is cool yes but for some how it didn’t easy or conveniently. i have to find the right angle to project it and some time it hard to connect with bluetooth. maybe it might helpful for iPad or iPhone.
