Journal 6
The problem I will talk about in this journal is lacking of feedback on bathroom doors. I personally face this problem manytimes. When I enter the restroom, I see a list of doors that are closed. I think these doors are closed because there are people occupied them. However, after waiting for a while, no one exits from these doors, so I try to open one of them and the surprise is no body was there. I think that I face this problem because doors do not have feedback to tell people if the closed door is occupied by someone or not. Thus, one solution to solve this problem is adding feedback. There are some lock that gives an indicator with red if the restroom is occupied and green if the restroom is not occupied. Adding feedback will help people to know if these closed restrooms are occupied or not without knocking the doors or try to open them. Thus, feedback is needed to solve the problem
