Automated Vehicles - PowerPoint
10 important questions on Automated Vehicles - PowerPoint
What happens when we have unrealistic standards?
- Outsized reaction in the face of inevitable accidents
- Drivers of Tesla's should have their eyes on the road at all times
- This is very hard if nothing happens for a long time
What is Human Machine Interface?
- Vehicle + human = joint cognitive system
- The HMI provides continuous interaction between human and vehicle
What are the main HMI challanges?
- Can the automated system:
- Handle longitdudinal and lateral control?
- Manoeuvre in the current environment and situation (roundabout)?
- Perform strategic aspects of driving (can it autonomously switch lanes or switch lanes)?
- Very dangerous if the driver can't answer the questions
Stimulate appropriate level of attention and intervention
- Lvl 2: Attention to the roads needs to be as high as during manual driving
- The higher the reliability of the system, the lower the attention, the higher the impact of a failure
- Two types:
- Absence of expected action
- Presence of unexpected action
- Solution: healthbar or heartbeat of the car (HMI)
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Study Smart. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Study Smart, which helped me to finish all of them within 3 months.
Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Study Smart. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Study Smart.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Study Smart to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Study Smart to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Study Smart get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Study Smart, I have passed all my courses on the first try. For me, StudySmart takes away the stress of wondering if I will pass or not.
Thanks to StudySmart, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
What are external HMI challenges?
- Intention!
Scalability
- Busy crossroad
- For who is the message meant?
Colour
- Compliance with road regulations
- Red, green, yellow, blue can generate confusion so can't be used
- Cyan!
How do you investigate on the road?
What is trust in automation?
- Uncertainty and vulnerability
- Not a unidimensional construct
- Situation specific
What factors do strongly influence dispositional trust?
- Culture
- Age
- Gender
- Personality
What is situational trust?
External variability
- Weather conditions
- Road conditions
- Self confidence
- Mood
What is dynamic learned trust?
More slow, develops based on all the different situations that happen on the road.
What is trust calibration? What are the guidelines?
- Avoiding overtrust and undertrust
- Design for appropriate trust, not greater trust
- Show the purpose of the automation in a comprehensible way to the operators
- Train operaters regarding its expected reliability
- Carefully evaluate any anthropomorphizing of the automation (adding avatars, voices, human elements)
- Be careful because can increase trust but this does not correspond to appropriate trust
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
