Take-Over Requests after Waking in Autonomous Vehicles

Round 1

Reviewer 1 Report

This paper” Sleeping in an Autonomous Vehicle? An Exploratory Study of 2 Take-over Requests with the Most Preferred In-car Activity” proposes a novel method to add Take over requests through feedforward timings and presentation modality. Overall, the paper is an interesting one with reasonable solutions and promising experimental results. However, there are quite a few issues to be resolved before considered for publication.

 

• Revised the paper title, why ? in the paper title, title is too long
• In related work, add this recent paper from the applied science journal related to posing estimation of driver head

https://doi.org/10.3390/app112411600

• There is no need to add research questions in the section 3.3.2.
• Construct some framework diagram of your approach
• In evaluation, section write some formulas to measure driving performance.
• A comparison with the state of art in the form of table should be added in the discussion section.
• Future work is unclear and undefined. you can work through some deep learning model, for this yolo CNN model architecture real time would be good , see this paper from applied science journal

“Real-Time Hand Gesture Recognition Based on Deep Learning YOLOv3 Model.” ,doi:10.3390/app11094164.

Reviewer 2 Report

The paper is quite interestinga nd provide relevant results but some items must be improved before publication:

The main concern is related to paper structure. It is quite strange and perhaps too long. There are several references. Are all of them necesary for the purpose of the paper. Which is the novel approach of the paper? Can some comparisons with all those references be included in the paper?

The experimental method is explained too late. Too many things are included in the paper and this is not the usual way to present a scientific paper that must highlight novelties and focus on them.

On the other hand, final results are quite short in comparison with the other parts of the paper. 

Driving simulator has clear drawbacks and limitations. Please, discuss them and explain if they condition the results.

Reviewer 3 Report

Title: Sleeping in an Autonomous Vehicle? An Exploratory Study of Take-over Requests with the Most Preferred In-car Activity

Synopsis: In this paper, the authors used an AV simulator to measure driver’s cognitive and physical loads related to Take Over Requests (TOR) while performing non-driving related activities.

Technical Comments:

The paper is an important contribution to the understanding of safety critical conditions involving AVs. I have some minor comments-

1) Please expand the acronyms as much as possible for figure captions and especially the conclusions.

2) Figure 14-16: Please include the axis labels.

3) The conclusions and the discussions section will be benefitted from further discussion on the implications of this research. How would the existing L3 AVs incorporate your findings? How about L4/L5 AVs?

Thank you!

Reviewer 2 Report

The paper has been improved but there are some issues that must be considered before publication:

• The paper is too long and it is not completely focused on one aspect. Perhaps it is more convenient to focus on some of the results.
• Phase 1 and phase 2 are essential for the paper? Could be one of them removed or shortened?
• Revise the paragraph "Our study focused on..." in the conclusions section because it is not clear. Stating the last two paragraphs in this section with Our... is not elegant.
• Future works must be presented as some specific task that are being developed or will be developed or are necessary for some purposes.
