What do you get if you cross the 'summer of love' with a 2012 Symbian utility? You get Sensor Tools, whose screens (below) have to be seen to be believed in terms of fonts and psychedelic colours. What does it do? It gives feedback on the numbers coming from your smartphone's sensors, as the name implies - gyros, GPS and magnetometer.
The last time I saw graphics like these was browsing through a Cream gatefold LP sleeve from the 1960's! Here's a rundown of what Sensor Tools actually does:
The basics of position and compass heading are here, but also subtleties like data latency (I'm guessing this effectively represents how accurate and up to date your GPS fix is?) and compass accuracy. There's also some flexibility in terms of the units used.
Good to see all the satellites shown graphically - this view disappeared from Symbian when Symbian^3 arrived - the blue marked satellites show which are currently locked on and providing information to your position fix. Note the time check - never mind going online to an Atomic clock, you can check your phone's time from satellites (FX: puts on Dr Who voice) in SPACE. Still seems cool to me...
The gyro data is new to me too, this is the first time I've seen it all broken out in terms of raw numbers. The theory is that you can use Sensor Tools to 'check' the sensors in your phone, but in practice it's a bit of geeky plaything - and what's wrong with that?
