Inertial Elements are doing the same based on accelerometer, gyroscopes, compass and pressure sensors and WiFi/BLE, But instead of hand held devices they are using shoe mounted devices.
Hi Elie, Attempting to correlate signal strengths (RSSI values) with the distance from blue-tooth devices isn't going to get you a 10cm precision especially indoors where radio signals are reflected and scattered. Using the Raspberry Pi devices listening to the RSSI values from various blue-tooth phones I found I could only reliably detect when the device was within 5 metres of the Raspberry Pi. I therefore came to the conclusion that the solution was good for finding which room a person is in within a building, but not the exact whereabouts in the room they are. In the video I did show a scatter graph of distance / RSSI values and although you can see a clear reduction in RSSI value for increasing distances, the scatter of results was quite wild! I explain this starting at around 10:25 in the video. There are techniques for smoothing these results discussed in this paper if you are interested: s2is.org/Issues/v1/n2/papers/paper14.pdf, although I've not tried this. I hope this helps Mark
@@markbaird-mbcoder Hi! I am pursuing my masters and i need some guidance to finish my project work. Do you have an idea regarding ibeacon(BLE). If you know the interfacing of ibeacon with raspberry pi using python, please do help me. Even if you have any information about ibeacon please do share the papers.
I am doing this kind of project but with ESP8266 to detect the client devices mac address and rssi. I am gonna create a web app where user can sign in and locate themselves in an indoor environment. May i know is it possible for me to get the mac address of the user that signed in into the web app ? Any javascript code available ?
Hey Muhamad I'm doing indoor localization project with esp8266 as yours can I ask some questions? İf it's possible could you give me any contact adress?
@@ahmetislam5899 hello guys, I am also doing a project related to indoor positioning. If you know something about it/ interested in, please contact me at hei89708@gmail.com for further discussion!
Do anyone have an idea regarding ibeacon(BLE). I need help to complete my project. If anyone know the interfacing of ibeacon with raspberry pi using python, please do help me.
fantastic, could you please provide us with document lesson about how you have done it
do you know how to get rssi value so that I can manipulate/use it in a python program in raspberry pi?

Thanks for the video! Do you think with this technique it would be possible to achieve

did you use python for that ?

use the library called pygatt
