AI Thread 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?

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...

Thread 'Is AI hype?'

In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...
