Visibility, The macbook pro’s system is very easy to use; it’s similar to that of any laptop but almost simplified. Everything is mapped on the keypad, including each buttons’ action, and use. Also, the whole system runs mainly on the straightforward click and drag concept. At the bottom of the desktop, all my programs are stored, and as I roll my mouse over each program it enlarges therefore making it very visible to the user. Also, the system preferences icon allows you to go in and change your lighting, sizing, and overall preferences of the system. This is very useful because this way you can modify the visibility and options of your screen to best suit your needs. Affordance, The affordance of the macbook clearly fits with its function, its compact and light making it easy to transfer from place to place. It’s still fairly small, making it easy to hold and travel with. The buttons are all clearly labeled, and the keypad resembles any basic keypad making it easy to use for anyone. Mapping, the mapping of the keypad is similar to that of any keyboard, therefore the consistency makes it incredibly easy to use. The on/off button is a larger circular button just next to all the letters and numbers. It’s quite clear that it’s on/off because of its size and placement on the pad. Constraint, there may be various cultural and age constraints because you have to be able to read and write the English language to use the keypad, or to generally do anything on this system.

Visibility, I don’t like this alarm clock, because from far away the time tends to blur together, and its unreadable. Also, the buttons are all over the place and have no visible pattern. The most difficult issue is after I set my alarm, I have no idea if it’s actually set right or if it will even go off. There is no icon saying the alarm is set. So I just have to hope it goes off so I don’t miss class in the morning. Affordance, the actual design of the clock is quite basic, nothing special. However, the size of the buttons are tiny and the on/off button is a switch on the side, but if you push it the wrong way it will alarm so it’s quite difficult to turn off, especially when still sleepy early in the morning. Mapping, the mapping of this alarm clock is very poor because one may misinterpret what each button does, and since there are no labels it’s difficult to figure out. Constraint, the constraints of this alarm are basically just if you don’t know which button does what then it is very difficult to set the alarm, or turn it off. If the mapping were clearer, then there would be very few constraints.
