2) FEEDBACK: Toshiba Washing Machine

Feedback send information or communicating the results of an action. (Norman, 2013)

Figure 2: Toshiba Washing Machine

This is the washing machine in my house.  As I always use washing machine at laundry outside before I move to my new house at Academia Lane, so I did not face any problems with it. By the way, the difference between this washing machine with the washing machine at laundry is it has more functions, like regular, speed and others. It uses red lights besides each option as the feedback. So, I can know which state or what options I chose by looking at the red light. Furthermore, red light is eye catching and obvious. The washing machine also use sound as the feedback such as “beep” sound once a button been pressed and a long and continuous “Di” sound for the washing process is completed. In a nutshell, this washing machine has a good interface and easy to use.
