“Your solution already exists.” This critique matches the challenges I faced when designing my solution. Other people may find my design solution to be ineffective. I did not search for existing solutions since I was designing for myself. It is true however that the solution is already present and confirms that it is a machine error people deal with. The critique also indicates that not all people have issues with this machine error. In conclusion I feel that it is a good idea to understand the opinion of the people before choosing to design.
