hi everyone . i have a simple question . i need a sensor or an idea for detect how far a human is moved . let me explain it :
i want to know how far i am walked
so why i'm not using google maps ???
Because it is not accurate, especially at indoor places
I need an accuracy of about 4 to 20 inches (10 to 50 cm)
I do not know exactly what to do. I know I can not use UltraSonic. So what should I do?
Use a mouse sensor? Problem with taking steps
Use wheels on shoes? I think it is stupid
Do you have an idea / know a specific sensor?
