Before reading this, I had no idea there were so many inventions for the disabled and I did not think about the work that went into designing them. Because everyone’s situation is different, the devices that help aid them are difficult to standardize. Additionally, if that person has to use the technology for the rest of their lives, it has to be one that they enjoy and are comfortable with and because of that, for those creating the devices, design has to be up to par.
I personally like the point about simplicity because it really focuses in on what’s important and in this case, it’s to give the user a functionality they need. It should be simple enough that it’s intuitive and useful at the same time, yet there’s still a like of devices out there that are too confusing to use.
