Almost there, second to last week!
So this week, I had a total of 30 excel files full of 1800 or so data points, I spent almost all of this week. Thinking about it, the motion sensors picked up data every 20 milliseconds in each 6 second trial, and some of the data was incomplete because the cameras could not pick up the motion sensor.
So this week, I had a total of 30 excel files full of 1800 or so data points, I spent almost all of this week. Thinking about it, the motion sensors picked up data every 20 milliseconds in each 6 second trial, and some of the data was incomplete because the cameras could not pick up the motion sensor.
So I had to export the data from each of the excel files and interpolate it with a MATLAB function. I had to fill in the blanks for the data, so that I can plot the data and look at the velocities. WIth the velocities, I can analyze the movement of each of the sensors, to look at the overall motor movement of my hand and the prosthetic.
I have to finish my presentation for the 13th, so most of my week was also spent compiling the info that I had gotten from the papers I read. It was really interesting to put all of that information in front of me and see some of the problems that I had noted. Possibly the most important knowledge I gathered was that the willingness to accept and adapt is the most important aspect for a prosthetic user. They need to accept that their life is different and they need to adapt and learn how to live their lives as close to how it was before. They need to also accept that having a prosthetic makes them nothing less than everyone else. And to make this transition easier, is what I hope to help with my research.
So that was my second to last week, it was fun, just compiling the info and data, which I will be analyzing soon. As usual, if you have any questions, feel free to ask them in the comments below. Thank you!
Hey Sri! Glad to hear you made some good progress this week :D It's almost over!!! Quick question: why couldn't the camera's pick up the sensors? Like what does that mean in layman's terms? Sorry about the silly question; thank you, and good luck :D
ReplyDeleteHi Saleena! Thank you! Yeah, so when I curled my fingers to grab some of the objects, the motion cameras did not pick up the sensors, and that led to some data issues. Sorry about that, I hope this helps. Thank you!
DeleteSri,
ReplyDeleteYour project seems like its progressing really well. Just a bit longer till you are done. Good luck preparing for your presentation and I cant wait to read more.
Thank you!
DeleteHi Sri! I'm glad that your project is coming together! I wish you luck in finishing your presentation. Also, would the data be more accurate if sensors picked up the motion more than every 20 milliseconds? How did you get the data to fill in the gaps?
ReplyDeleteHi Syndney! Thank you! Yeah, so the data was extremely accurate given for the function, it was really minute and to the lowest time increment we could do, so that aspect was fine. With the data, I used linear interpolation on the x,y,z coordinates, so the function would map a line of best fit, and then use the two most recent data points to calculate the data point that was missing.
DeleteHi, Sri! What were some of the problems you noted when looking through your compiled information? Good luck in pulling it all together, though I'm sure you won't need it.
ReplyDeleteHi Fajr! Yeah, so when compiling the info for my presentation, I realized that I got the results that I wanted but the nature of the grasping function limited me. Because when grabbing the objects, the fingers curled in, covering up and causing the motion sensors to briefly stop tracking. It was a small error but luckily, the interpolation fixed it. Thank you!
DeleteHi Sri! It is awesome you got so much data! I am excited to see your final presentation! Are your results looking as you had expected? Or is it something new? Thanks!
ReplyDeleteHi Julia! Yeah, they show the mechanical nature of the prosthetic and so that aspect was successful! Thank you!
DeleteHi Sri. I want to commend you for obtaining an enormous amount of data. Out of curiosity, why was your camera unable to pick up the motion sensor? Also, when you were filling out the blanks in your data, how were you able to determine which velocities to fill in? As always, I liked how you looked the social and mental effects of having a prosthetic. And sorry, if you've already mentioned this, but how will you correlate your data to these social and mental struggle of amputees? Can't wait to see the final results of your project. Best of luck!
ReplyDeleteHi Jason! Thank you! So the motion cameras are all around me(I will clarify it with some pictures in my week 10 post later today), and when I curled my fingers to grab some of the objects, the motion cameras did not pick up the data. I didn't fill in any velocities, it was using linear interpolation on the x,y,z coordinates, so the function would map a line of best fit, and then use the two most recent data points to calculate the data that was missing. I wont be correlating it with the struggle of amputees, that was something that peaked my interest to analyze the social attitudes towards prosthetics. So both are separate aspects of my project,one empirical and the other experimental. Thank you!
DeleteHi Sri! Do your findings indicate any issues with the current design of the prosthetic? Also, how will you relate your data to improving the design?
ReplyDeleteHi Anthony! Yeah, so when my project changed it became less focused on how I could change it, and more focused on how well it had replicated the action of grasping. That being said, it was really eye opening as to how successful the prosthetic was. I used my data and was able to see how well it's movement related to the movement of my hand. Thank you!
DeleteHi Sri! It's so great to see your project coming together! Are you correlating the psychological side of having a prosthetic with your results? I am excited to see your last post. Until then, I wish you the best of luck with putting your results together!
ReplyDeleteHi Michelle! Thank you! So the social attitudes of the prosthetic center around the emphasis of function, so I have psychological aspects that I will present on, but I wont be linking them to my data. Thank you!
DeleteSri,
ReplyDeleteDo you think you got what you wanted out of this project? I think all the research and everything you have been working on is so cool and I think these basic analysis skills will definitely help you in the future. Only two more weeks but I am really looking forward to your final report!
Audrey
Hi Audrey! Absolutely! I wanted to see how well the function of grasping was replicated and I got to learn about Prosthetics. It was a great experience. Thank you!
DeleteHey Sri! I can't believe we're already in our last week. Quick question: why couldn't the camera pick up the motion sensor? Also, what aspects are you going to study with making the prosthetic transformation easier? Can't wait to hear about your last week!!
ReplyDeleteHi Korina! Yeah, so when grabbing the objects, my fingers would curl in so the motion cameras could not pick up the motion sensor since my hand covered it up. I hope that helps! Thank you!
