Anushka’s Status Report for 4/30
This week, I mainly focused on different hologram designs. We have three options right now:
- The angles in the pyramid are 53-53-127-127, and the dimensions are for a hologram that fits an iPad.
- The angles in the pyramid are 53-53-127-127, and the dimensions are for a hologram that fits a monitor.
- The angles in the pyramid are 60-60-120-120, and the dimensions are for a hologram that fits an iPad.
So far, we have tried all three, and the last one works the best but only in total darkness. Next week, we’re going to try to test new angles before the demo day, then probably pick the one with the greatest visual effect. I’ve also been working on the final sewing of the device onto the wrist band. We adjusted the height of the sensors since our hand was interfering with the input. I have also been working on the poster for our final demo.
This is the final official status report of the semester. We have all the parts completed sufficiently, but we know there are always areas of improvements. We’re going to try to make minor changes throughout the week before demo day, but otherwise, we have a completed product! I am most concerned about how it will go overall. We have tested our product amongst ourselves, but we are aiming to test it on several participants before demo day and final paper. We are excited to show everyone our progress and what we’ve learned!
Joanne’s Status Report for 4/30/2022
This week was final presentation week so we as a group worked a lot on polishing the slides and doing testing on our prototype. We conducted a lot of testing on latency, performance, accuracy and that was our focus for the latter half of the week. The early parts of the week, Edward and I took time to debug our unity/gesture code to provide better model translations. Before there was a bug of irregular spikes in the model’s movement when given gestures. However we were able to go through our whole code, and figure out what caused the issue. We were not resetting the appropriate values after the completion of one gesture, thus causing issues with data calculation. Our integrated model works fairly well in response to gestures now! After that we have been focusing on testing + hologram portion. I added new features to the web app which include changing models (now there are three models that the user can switch between), and incorporating the previous sensor data visualization we had with our current web app. I will continue this week to finish up the UI for the web app and help with finalizing other portions of the project such as display/hologram creation as well as the final report/ poster.
Team Status Report for 4/30/2022
This week, we finally finished a working demo of the wearable and Webapp! Joanne and Edward spent several hours debugging and bug squashing in order to properly filter out the incoming finger location data from the wearable. Eventually, they converged on a working system. See video here.
The current issues remaining are that WiFi is fairly slow and negatively affect latency. It isn’t too bad, but it makes our system less real-time than what we wanted. If we were to do this again, we would use BLE or perhaps some other wireless protocol.
Anushka worked on refining the hologram design. She design several version of the hologram and cut them out to see which one gave the best effect. So far, the pyramid with angles that are above 60 degrees and on a big screen work the best. She has also started working on the encasing for the hologram. At this point, we’re not really sure how to improve the visualization without changing it altogether, so we might try bigger angles on smaller screens throughout the week to see what gives the best effect.
We are on schedule to have something for the demo. This week we will work on polishing everything up and making sure things are in order to not blow up at demo day.
Edward’s Status Report for April 30
After I submitted last week’s status update, me and Joanne worked on fixing the bugs in the Webapp. We spent several hours cleaning up the code and trying to see what was causing the issues. We have been seeing that the model freezes up or moves in the opposite direction when the wearable sends is finger locations. After debugging, we finally found the issue and fixed it up. This video was made right after we fixed all the bugs!
This week, I prepared for and worked on the final presentation. Anushka was feeling better, so I gave her the wearable for her to properly sew on. So, without any hardware, I spent most of this week working on the final presentation.
I am on schedule and pretty much done with the individual tasks I needed to get done this semester! Next week, I will help on polishing everything for the final demo. We still need to build the hologram pyramid, so I will be helping Anushka on that. Super excited to demo our system in the final demo!
