Smartphone App Designed to Help Early Detection of
I am using two Bluetooth Modules (STM32 board) and 3rd will be mobile device having bluetooth on the device. I want to detect this mobile device using tringulation in the range of 10 meters.... CaMeasure lets you use your camera to measure size or distance. It does this in one of two ways. For smaller objects such as furniture, the app asks you to put an object of known size, such as a sheet of paper or a credit card, by the object. The app then uses that to calculate size. Or for large objects, such as a building, a virtual object is superimposed on the building, and you scale this

To determine the distance you would also need to use triangulation techniques to determine the position of a mobile. You can also set up a number transmitters in your environment and measure against each one. Knowing the positions of these transmitters you can then work out the position of the phone....

How to Boost Your Smartphone/Tablet Wi-Fi Reception
We look at the problem of using accelerometer in smartphones to detect whether the user is at a metro train station or in a metro train. Currently, we have solutions to detect simple activities, such as sitting or walking.... where d is the distance of the human body from the smartphone and v s is the speed of sound in air. When the subject’s chest moves because of breathing, the distance (d) to the smartphone and the corresponding time delay of its echo (?t) at the microphone change.
Measure anything with your smartphone or tablet camera
Your Timeline is private, so only you can see it. Timeline will include where you travelled and the way you travelled from place to place, like walking, biking, driving, or public transportation, during the times when you have Location History turned on. On your Android phone or tablet, open the Google Maps app . Tap Menu Timeline . To see another day or month, tap Show calendar swipe left... Motions like swinging, tilting, rotating, shaking is detected using accelerometer. The value of XYZ is used to calculate and detect the motions. Besides mobile, the accelerometer is used to measure vibration on cars, machines, buildings, process control systems and safety installations.

How To Detect Distance Traveled Using Smartphone
An Algorithmic Approach for Detecting Car Accidents using Smartphone Mitali Bhokare 1, Sumit Kaulkar 2, Anand Khinvasara 3 , is the distance traveled since the last time the variable ‘z’ switched from value 1 to 0. Mx: is the minimum acceleration required for an acceleration event alone to trigger accident detection. My: is the minimum decibel required for an acoustic event to trigger
- Information about distance traveled, facial expressions from photos and emotional content from text messages also may be used in the final assessment. Because of the sensitive data the app needs to access, user privacy is a priority. The app uses encrypted data and replaces the user’s name with a coded ID. This way, users don’t need to make changes when using their smart devices. Using the
- Note: calculating the distance using RSSI depends on many factors such as the type of phone and how the user is taking the smartphone (in the pocket, in the hand, in a bagpack, etc). What about privacy?
- Since they are a known distance apart you can infer the true distance traveled without having to do a lot of math regarding the camera scene reconstruction. Note I am not making a new answer for this since @hauptmech is saying exactly this (but in a more professional lab setup).
- To determine the distance you would also need to use triangulation techniques to determine the position of a mobile. You can also set up a number transmitters in your environment and measure against each one. Knowing the positions of these transmitters you can then work out the position of the phone.
