I'm thinking of developing an app that finds the distance of user walked. Firstly i tried to implement it via GPS location but is there any different idea with using sensors?
Basicly my app is; The user clicks the start button and the walking starts The user clicks the stop button and the walking ends And app says you have walked bla meters.
I want to implement it without location (latitude or longtitude)
Is there any other way?
Maybe that can help you
This application count steps, calculate approx. distance and speed based on user's step length .
Your only other choice is to hook into the accelerometers and figure out what a "step" looks like. Then you'll need to prompt the user for how long their stride is, how "bouncy" they are, etc...
It won't be easy - a step will look different depending on how the phone's held: strapped to the user's waist in a belt holder, held in their hand, bouncing around in a purse, etc... A person with a light footstep won't produce as pronounced a "bump" on the sensors as someone who really slams their feet down, etc...
As far as I know the only way would be with locations (GPS or network-based).
There's one (silly) idea I could think off:
If the device has a gyroscope, you could roll the phone over the ground, and together with the diameter of the device, you could calculate the distance ;)
But your best bet will still be usage of locations.
