Consider wearable technology such as Fitbit or the Apple Watch; what is a design consideration for wearable technology? 

In class, we got to use the MIT Moral Machine. We also discussed AI and machine learning and ethics. Why is ethics so important when we design systems such as autonomous vehicles?

Consider a nuclear power plant operator working a morning shift (3am – 12pm) and an automated system that manages the plant. The automation integrates information from multiple places within the plant and provides alerts to the operator if there are values out of range. When the afternoon shift operator arrives at 12pm, they notice the temperature in reactor 1 is high and asks the morning operator how long the temperature has been rising. The morning operator replies that they have not received any alerts about the temperature in reactor 1 and was not aware that the temperature had been rising. The morning operator mentions that when they checked the temperature at 4am it was normal, and they were not aware it had changed. System diagnostics reveal that the temperature had been steadily rising since 5am but was not yet high enough to trigger an automated alert. Within hours, reactor 1 experiences a partial meltdown. What source of automation intervention failure is this describing?   

In terms of improving situation awareness, which of the following is an example of improving situation awareness in level 2 (comprehension)? 

We are going to test driver performance with and without cell phone use. However, we also want to evaluate if driving in the day or the night impacts performance while using a cell phone. What type of experimental design is best for this setting? 

You are working in a bakery. The first thing you and your coworker do each morning is make all the dough for the breads so it can rise. Your coworker measures out all the ingredients and hands them to you two feet away at the industrial mixer. You operate the mixer. When the mixer is running, you ask your coworker for the next ingredient, but they do not hear you. You raise your voice, but they still do not hear. You end up having to shut off the mixer for them to hear you. What can we say about the sound level in this workspace? 

Consider signal detection theory. A very high value of sensitivity (d’) indicates that the signal and noise curves are: 

Which of the following type of acoustic information is considered “wanted” information? 

Danielle works at a manufacturing facility. Their job is to inspect product components for defects. The facility has been having quality control issues and sending parts with defects to retail partners and the stores have been complaining. To reduce how many defects make it out of the facility, the supervisor tells Danielle that for every defect that makes it past their inspection they will receive a pay cut of $2.00/defect. How does this incentive impact Danielle’s response bias? 

In human information processing, what happens in the sensation stage?
