Title: Design of Future Things
Author: Donald Norman
Publisher: Basic Books, May 2009.
Summary:
Chapter 3 - Natural Interaction:
This chapter focuses on the importance of natural interaction. Most designs use beeps and flashing lights to provide the user with feedback. Don Norman argues that the designers should instead use natural signals. These include environmental sounds and lights, like sound of boiling water in a kettle, thus making them less annoying. Also these types of feedback are easily recognized.
Author also talks about implicit communication and how it can be used in intelligent designs since it provides a feedback without causing interruption. He talks about how softer sounds can be used in intelligent designs to provide feedback without causing annoyance. Furthermore, he talks about affordances and how they can be effectively used in good designs. Affordances provide cues to the user as to how to use the product.
Lastly, the author talks about predictability and natural safety. He mentions that machines should work as predicted by the user. This helps the user to anticipate the machine's behavior and plan actions. Thus the machine and the user can work in coherence. By the idea of natural safety author implies that designers should make dangerous things look dangerous however make them safe internally. This is because as things get safer, people tend to take more risks.
Chapter 4 - Servants of our Machines:
This chapter talks about the drawbacks of automating. Since modern machines perform most of the tasks themselves, we are becoming dumber. In fact, we are becoming servants of our machines, depending on them for almost all of our tasks. However, we are so used to using machines that this situation can not be reverted. Whenever we see a new technology, it always brings along new benefits, however, what it also brings along with it are some unanticipated problems.
To provide with some examples, author mentions cars that have automated features like cruise control. He states cars are the most advanced area of automation that impact our lives in the most direct way. Eventually cars will get even more automated and start communicating with each other, sharing information. He mentions that complete automation is reasonably safe, however, the present state of partial automation can be disastrous.
Chapter 5 - The Role of Automation:
The author states that "automation is needed to eliminate the dull, dangerous and the dirty." However, automation can have drawbacks. It changes the way tasks were performed before, sometimes creating additional work. Automation also adds to maintenance. Also, automation doesn't necessarily increase the intelligence of the machine.
Next, the author talks about automation and intelligent augmentation. Automation attempts to infer the intentions of the people while intelligent augmentation provides useful tools and lets the people decide when and where they want to use them. Automation is helpful when the jobs are dangerous, dirty, laborious or boring. However, for other cases, author suggests using intelligent augmentation.
Chapter 6 - Communicating with our Machines:
(Chemical Plant Control Room - Controls and Feedback indicators)
This chapter talks about how we communicate with machines and how machines communicate with us by giving the necessary feedback. Communication always occurs between two entities and it helps users to form mental models. These mental models help the users to anticipate the machine's behavior and provide clues to troubleshoot the machine when something goes wrong. However, in modern machines, the indicators that provide the necessary feedback are becoming more silent and hidden, making it harder for the user to guess what's going wrong. Feedback is very necessary to inform the user if the system is working properly. A good design should continuously provide the user with a feedback to indicate the state of the machine, without annoying the user.
The author mentions that the feedback use natural sounds and lights so that they don't get annoying. However, alarm sounds should be annoying since they are meant to catch attention. However, they should not create panic. Also, there should be a natural mapping between the controls and the actual tasks. Some of the characteristics of good design are - predictable, natural feedback signals, good conceptual model and natural mappings.
Discussion:
Chapter 3 - Natural Interaction:
I tried to relate everything that the author mentioned in this chapter with my personal experiences and I realized that everything that the author said made complete sense. I love to use products that aren't too flashy and noisy. Also, I really enjoy using products that are easy to learn and provide me with affordances which expedite the learning process. Speaking of natural safety, it's my personal experience that I used to drive carefully in my old car (from the 80s) and as soon as I got my new car, I started cruising at more than 80mph. So I guess it's indeed important to make dangerous things look dangerous.
Chapter 4 - Servants of our Machines:
I completely agree with the author when he says that the process of partial automation is dangerous. For example, the automatic transmission automated the transmission shifting process, the cruise control in the car automated the need to hold down the throttle. However, the steering wheel is not automated. This is partial automation and I have seen people sleeping while driving, which can be extremely dangerous and sometimes fatal.
Chapter 5 - The Role of Automation:
I do agree that automation can make us handicapped. We become so accustomed to automation that we can't work without it. So, its definitely a good idea to limit automation for performing dangerous, dirty, laborious and dull jobs. For other tasks, intelligent designs can still be implemented without automating the tasks.
Chapter 6 - Communicating with our Machines:
This chapter was a little repetitive. Most of the content was repeated from earlier chapter and the Design of Everyday Things book. Even though the content was repetitive, it was not worthless. The information presented made complete sense and the examples mentioned in the chapter were very convincing.
