Month: October 2021

This week we worked together on finalizing our presentation and ordering the parts we needed. We continued to research parts and tools such as the beam forming and comparing various types of microphones.

This week I focused on editing the slides for our design review presentation and preparing to present. I also began working with my team on our design review report. In addition, I worked on setting up the Node MCU for wifi communication. 

This week I plan to continue working on the Design Review writeup and do some meaningful research in my focus areas to flush out our design review and implementation details. 

This week I spend time researching methods that take into account uncertainty and methods that combine sensor data to localize a person.  From our collective research, we concluded that we wanted to focus more on IR sensors for tracking movement around the room and use the microphone to enhance and verify a person’s position especially in cases of little to no movement. We decided to switch from sound to PIR motion detection for our primary input data for locating, because our TA brought up latency issues when using analog sound data from microphones and we found a lot of papers that used PIR sensors for tracking positions around a room.

We received a few parts at the end of the week, so Ryan and I were able to set up the raspberry pi and test out one PIR sensor’s range capabilities. We also collectively worked on our Design Presentation Slides.
