also see Apple's iBeacon.
i have never been able to get these devices to work well enough for gps type apps. so glad to see someone is trying a new approach.
- dmritard96 11y agoWe are also, https://flair.co https://flair.co, but more room occupancy than navigation. Navigation and trilateration with any accuracy is incredibly difficult.
- simmons 11y agoI'd be curious to hear what the challenges are. Is it simply that signal strength is too noisy to be used reliably? (I.e., interference, multipath, attenuation when the subject walks behind furniture, etc.) I was attending a theatre show a few days ago, and thought that the sound system could deliver a better experience if the positions of mics on stage could be tracked as cast moves around, and the mixing adjusted accordingly. Naturally, BLE was the first thing that came to mind.
- dmritard96 11y agoThere are a lot of things. The device's antenna pattern and orientation are a big part. Metal in/around any of the devices. Signal/Noise. etc. You can try to improve with a lot of calibration but it will also be subject to noise from every audience members bluetooth radio too.
