Seeing as how Androids have Orientation Sensors, I couldn't resist having a go at an app to 'guess' the height of an object, using the measured distance to its base and the angles to its top and base, as measured by sighting along the centre of the android screen. Obviously not very accurate, but the only way to find out if it's of any use, and maybe better than a straight guess, was to write an app and test it.
So, here: Android Apps (http://www.blocklayer.com/android-apps.aspx) , at the bottom of the page are links and QR code to download it.
Just enter your own height, and the measured distance from your toe to the base of the object and hit 'Set My Height + Base'.
Then (only) if the base (ground) is not level, sight through the screen at to the base of the object and hit 'Set Base Angle' to set how far high or low the base is (compared to your toe). It will speak the result.
Now hit 'Guess Height' and sight along the screen to the top of the object directly vertical from the base, and the app will repeatedly speak the approximate height.
Obviously you couldn't rely on the accuracy of the results, but it's interesting to see how close it can get, ad what may be possible as the technology (and devices) evolve.
So what do you reckon? -- Waste of time?
