Gravitation: Accelerometer based hourglass clock simulator

Posted by Boffill Sunday, September 7, 2008


Gravitation (HourGlass)Gravitation is actually hourglass clock simulator that uses the built-in accelerometer to detect the phone movement and simulate the sand moving through the bulbs according to phone position and moving direction.

So every time you change device's position, an observer updates the acceleration values in each axis, it's range is from -360 to 360.

Just like the real hourglass, it consists of two glass bulbs placed one above the other which are connected by a narrow tube.

One of the bulbs is filled with fine sand which flows through the narrow tube into the bottom bulb.

Once all the sand has run to the bottom bulb application trigs the vibrator to warn user that time is over and that it is necessary to invert device in order to measure another time. It is also possible to change the period from 15 sec up to two minutes in steps of 15 seconds.

Application has a pretty good physics but high-quality graphics is as important to realism as physic and unfortunately graphic sucks a little bit and therefore clock isn’t as realistic as it should be.
