[00:00:03.190]Hello everyone. My name is Mohammed Sbai.
[00:00:06.760]I'm a mechanical sophomore mechanical engineering major here at the university
[00:00:10.660]of Nebraska Lincoln. This summer,
[00:00:12.490]I conducted research at the Nimbus lab under Alisha Bevins and Dr. Duncan
[00:00:17.080]During this video,
[00:00:18.190]I will talk about my projects where I will be given an introduction to talk
[00:00:21.820]about why is what we did is important. Our goals, the methods that we used,
[00:00:27.430]the results we get and what we learned from them and the future
[00:00:32.080]work. ,
[00:00:34.720]my project is exploring proxemics for human small unmanned
[00:00:39.730]aerial vehicles,
[00:00:41.140]interactions within specific scenarios,
[00:00:45.490]small area vehicles
[00:00:51.220]are becoming increasingly useful and offer a variety of novel opportunities and
[00:00:55.690]services that we can benefit from
[00:01:01.750]such as fire firefighting and delivery,
[00:01:06.010]emergency response, a drone being a tour guide in the museum.
[00:01:11.020]infrastructure inspection, taking
[00:01:15.610]samples from rivers and lakes for studies,
[00:01:18.940]but innovation and developing those
[00:01:24.250]UAVs is important. And in order to benefit from their services,
[00:01:28.840]we need to learn and understand how to interact and communicate
[00:01:33.340]properly and in an efficient way
[00:01:41.980]in my projects
[00:01:43.600]I focused on the proxemics part of the human UAV interactions.
[00:01:48.250]And you probably wondering what is proxemics and the study of proxemics,
[00:01:52.660]which classifies as a non-verbal human behavior has been around for
[00:01:57.460]a while to study the distance human preferred
[00:01:59.310]to stay from other in different environments,
[00:02:02.500]but it was mainly focused on human-human interactions
[00:02:08.140]and with the creation of UAVs,
[00:02:09.820]it became a necessity to study the proxemics for
[00:02:14.680]human-UAV interactions and how it differs from human-human
[00:02:19.120]interactions and Proxemics zones break into
[00:02:24.040]four different zones, intimate space, personal space, social space,
[00:02:28.480]and public space
[00:02:33.940]For the goals,
[00:02:39.190]we set three goals,
[00:02:42.580]Understanding how the humans’ comfort distance to stay from the UAV
[00:02:46.750]differs based on the environment and the scenario and finding what is the
[00:02:50.500]factors that may make the participant more or less comfortable being approached
[00:02:55.270]by a drone so we as engineers and scientists
[00:03:00.100]can do to improve these human-UAV interactions.
[00:03:05.560]And for the methods We conducted all our experiments in the flying
[00:03:10.060]cage at the Nimbus lab here at the university of Nebraska Lincoln,
[00:03:14.050]that is equipped with 12 cameras that are connected, that are connected to
[00:03:19.600]A Vicon motion capture system that we used to collect UAV pose data
[00:03:24.280]during the flight path trials collect UAV data during
[00:03:28.120]the flight path trials. And here are some pictures of the cameras and on the left,
[00:03:32.650]you can see the cameras, and there are 12 cameras there.
[00:03:38.710]And the orange thing here in the middle is the position of the drone at that
[00:03:43.630]time, but who is flying these drones, right?
[00:03:48.930]For the mode of the flights
[00:03:51.300]the flight paths were sent autonomously to the Flame Wheel,
[00:03:56.310]which is the drone we used for our experiments.
[00:03:59.160]And you can see a picture of it here on the right, we had a copilot
[00:04:03.870]that is ready to take control manually in case
[00:04:08.640]anything wrong happens.
[00:04:10.710]And we invited five participants to interact with the UAV and were questioned
[00:04:15.330]about their experience interaction with the UAV before and after the
[00:04:19.530]interaction such as their background,
[00:04:22.680]if they have flown a drone before, what they think about drones,
[00:04:26.670]if there were any feelings during the experiment that impacted them in a
[00:04:30.300]positive or a negative way,
[00:04:31.920]Did they get nervous at any point of the interaction and why?
[00:04:35.310]we also asked them about Suggestions to improve theses interactions
[00:04:42.480]And the participants were presented with three different scenarios.
[00:04:46.650]the first one is delivering a package, where it will live the source location.
[00:04:50.940]For example, Amazon warehouse fly to your address,
[00:04:54.570]deliver the package and fly back to the source location.
[00:04:57.450]And the second the drone giving the interactant a tour in the museum
[00:05:01.260]Third one, a person is answering or approaching a barricaded area,
[00:05:06.240]and the drone will fly to that person and let them know that
[00:05:11.100]they need to leave.
[00:05:15.410]And for the results were obtained
[00:05:19.760]we found that all of the participants
[00:05:24.830]chose for the drone to not come any closer than 0.5 meters.
[00:05:30.110]Also, none of the participants been concerned about the height the drone
[00:05:34.430]flies. while
[00:05:35.810]it is like going to them or leaving
[00:05:40.000]the place where they are interacting,
[00:05:45.080]but when, for example,
[00:05:47.240]flying from the source locations to their house,
[00:05:50.060]so they haven't been concerned about what height the drone would fly.
[00:05:55.430]And for all of the
[00:05:57.260]5 participants, two of the five
[00:06:01.640]participants chose,
[00:06:03.440]the comfort distance from the UAV to be same in all three scenarios
[00:06:08.480](0.6 meters and 0.5 meters), which is falls in the personal space.
[00:06:12.920]And the other three participants did choose
[00:06:16.220]the same distance in two scenarios and
[00:06:20.940]different distance in the third one. And that can be explained
[00:06:25.400]with, for like the third participant, he chose a smaller,
[00:06:29.270]distance because probably
[00:06:32.270]he felt that the drone should be closer to the person,
[00:06:35.010]so it can show the seriousness of the situation.
[00:06:43.460]And
[00:06:47.750]if we took all those distances we collected,
[00:06:50.360]we find that seven falls in the personal space,
[00:06:54.230]six in the social space and two in the public space.
[00:06:57.860]While no
[00:07:00.080]person chose the drone to come to the intimate space and the
[00:07:05.030]overall, in all three scenarios,
[00:07:08.180]the mean distance for every scenario, they were pretty much close to each other,
[00:07:12.740]where we had 2.02 meters, 2.02 meters,
[00:07:16.340]and two point 2.22 meters. And for
[00:07:21.280]for future work,
[00:07:23.530]we found from previous work that the shape of the drone had an impact on
[00:07:27.880]the comfort distance,
[00:07:31.690]the participant preferred to stay from the UAV. So we can study that again,
[00:07:37.030]and we can get some results from that.
[00:07:41.170]And also adding a screen to the area drone where the interaction can watch a brief
[00:07:45.490]introduction about the UAV. That just explains.
[00:07:49.540]What do UAV will be doing?
[00:07:53.440]Also having a voice speaker on the drone,
[00:07:57.400]with the option to talk to a live person,
[00:07:59.440]if needed or creating an app that allows the participants to send
[00:08:03.910]commands to the UAV such as in the package delivery scenario,
[00:08:08.890]to tell the drone to back up,
[00:08:11.440]or this is a good spot to drop the package.
[00:08:17.380]And I want to thank all advisors, and mentors for their help,
[00:08:22.330]and especially Mel Krusniak, Ashraful Islam, Daniel Rico,
[00:08:26.350]Mohammed Ali and Chandima Fernando And also,
[00:08:28.540]I also want to thank very much the national l science foundation
[00:08:33.400]for this grant that made this project possible. Thank you very much.
