Click For Summary
Smartphones are equipped with accelerometers that can potentially provide x, y, and z coordinate positions over time. However, the accuracy of these values is limited, primarily due to the inherent noise and drift in accelerometer data. The frequency of receiving signals from accelerometers varies by device but typically ranges from 50 to 100 Hz. The minimum displacement that can be reliably detected is also constrained by these inaccuracies, making precise position tracking challenging. While double integration of accelerometer data can yield position estimates, it is generally considered imprecise due to cumulative errors. Despite these limitations, it is feasible to obtain position data with a tolerance for error.

Today's smartphones, almost every model have accelerometers. Is it possible that one can obtain the x,y,z co-ordinate positions from these accelerometers time to time?

And how accurate are these values? Means what's the frequency of receiving signals? What is the approx. minimum displacement that once can obtain from these accelerometers?

Thnx a lot.
 
Thread 'ChatGPT Examples, Good and Bad'
I've been experimenting with ChatGPT. Some results are good, some very very bad. I think examples can help expose the properties of this AI. Maybe you can post some of your favorite examples and tell us what they reveal about the properties of this AI. (I had problems with copy/paste of text and formatting, so I'm posting my examples as screen shots. That is a promising start. :smile: But then I provided values V=1, R1=1, R2=2, R3=3 and asked for the value of I. At first, it said...
