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

            In this journal, I will talk about a problem that I find in the printers in LVC. The problem I will talk about is present in all the printers, but I will focus in this journal in the color printer that is located in the technology center in the Lynch building since it is the only color printer in the campus and many students use it. Since printing is free on our campus, anyone can print without using a username or password. This means that all the documents students’ print are found in the color printer and here is the problem. When students go to the color printer to pick up their printed documents, they may not find them since their paper is mix with other students’ papers. The paper is mixed because there is only one color printer and all of the students send their documents to that printer without using username or password. Thus, all the printed papers are show-up in the same place. Personally, I usually did not see the papers I printed and I need to print them again. This makes me to hate using the color printer. Therefore, to solve this problem, I suggest connecting the printer with a slide machine so the student slides his/her campus ID when they want to pick up their documents from the printer. Sliding the campus ID, let only the papers that a student wants to print appear in the system and then the student can click on ‘print” to print his/her papers only. This way we will prevent mixing up the papers and losing them. By sliding our campus ID when we use the printer, the problem can be solved and the usability of the printer will increase.

                                                                 Payment Machine

How many times we swipe our credit or debt cards wrongly when we pay by payment machine. Some payment machines do not have a signifier like a small picture that shows the buyers the correct way to swipe their cards. Additionally, payment machine does not have constraint to show the buyers that they swipe their cards in incorrect way. The buyers only know that they swipe their cards in the wrong way if the seller tells them to swipe their cards again in the other way. Therefore, I suggest to have a feedback on these payment machines like a sound that let us know if we insert the card correctly or not. Also, it is better to have a constraint where the card cannot be swiped if we swipe it in the wrong way. Adding the feedback and the constraint principles will make the payment machine more usable.

Power Adapter with the indicator light

AC plug that can be removed

Extensions to roll the power cord

                                                                  MacBook Pro Charger

In this journal, I will talk about how usable the design of MacBook Pro charger is. The design of the charger meets the feedback principle. The charger has an indicator light in the power adapter plug. If this light does not turn on, this means that the plug is not connected correctly in the port. However, if the indicator light turns on, this means that the plug is connected correctly in the port. The indicator not only helpful in knowing if the plug is connected well or not, but it tells if the battery is full charged or not. If the light is amber, this means that the power is going to the battery. But if the indicator has a green light, this means that the battery is full charge. Furthermore, the power adapter plug can be inserted into the port in any way. I mean it does not have the problem as in the USB where you have to insert it in a specific way. The plug has a magnet where it can be easily insert it into the port. Even if there is no light in the room where you work on, you just need to make the plug near to the port and it will suck on it. Another feature that makes the design of the charger is usable is that the length of the cord is appropriate. It is not too long or not too short. In addition the AirPort Express has an AC plug that can be removed if it is not suitable tto the AC outlet. This feature makes the charger to be used with different AC outlets. Another nice feature in the charger is that it has two extensions on the sides of the AirPort Express that can be used to roll the cord around it in a nicely and organized way. All these features makes the apple charger usable.

                                                                       Earphone Port

In this journal, I will talk about how the placement of the design can affect its usability. In the above picture, the port of the earphone is located in the bottom of the phone. This placement makes me less use the earphone with my phone because it hinder my mobility if I use it. For example, if I insert my earphone in its port which is located in the bottom of my phone and I put my phone in the pocket of my pant, it makes me uncomfortable since it hinder my mobility. This is because the wire of the earphone is in the bottom of the phone and not in the up of the phone. i.e.,  the wire of the earphone will be inside my pocket and it may shorten the length of the wire. Also, when I lay down and write messages or read tweets and at the sametimes I use my earphone, it also hinder my mobility since the wire of the earphone is down. I do not have room to move freely without sticking with the earphone wire. So, I suggest to place the port of the earphone in the up of the phone instead of the bottom so it can give enough room for the person to move freely. In conclusion, this example shows how the placement of the port affects the usability of using the earphone.

In this journal, I would like to talk about the electric plug that I found in my room in the dorm. As you can see in the picture, the electric plug is located in one side of the light, which makes it invisible for me. I did not notice before that there is a plug in this light because I did not expect to find a plug on the light. I usually see plug in the wall and not in the light. Also, as what we know the affordance of the light is to give light to see and not to give a connection for electricity. Another reason that makes this plug invisible is that the light that has the plug is located on the ceiling of the room. Since the light that has the plug is located in the ceiling, this makes the plug invisible. The invisibility of the electric plug makes it less usable. For example, if I want to charge my phone, I cannot use it because the plug is on the ceiling and the wire of the charger is not long enough to reach it. In conclusion, I think that visibility and usability supports each other. If the design is usable but it not visible, the design usability will decrease. Thus, I suggest to have visible signifier like label on the light so people can get a signal that there is an electric plug in the light.
