This week I reviewed the questions that were raised when I presented the project. I researched solutions to the problems of non-radial Wi-Fi signals, potentially easier solutions to localization involving IMUs, as well as what it would take to make the idea work with CMU’s existing wireless access points, rather than us having to design our own. After meeting as a team, and looking at certain logistical and price challenges associated with us using special WIFI access points, I raised the suggestion of using optical tracking, where a video stream coming in from a camera could be used to estimate both the position and orientation of the user. As we were not yet sure of the feasibility of this as a technical solution, I have since researched a few longstanding approaches in the field of optical localization.

My progress is currently on schedule as I am still helping design the project and finalize what parts to order.
Next week I plan to make a small demo of optical localization to practically explore its feasibility with regards to the use case and target customer.
