sensorVector

Displays vectors from phone sensors.

Phones and tablets have many onboard sensors like accelerometer, gyroscope, magnetic field etc. These are what those games with tilt-to-steer controls use. But, you can use these sensors to perform physics experiments too. There are many apps out there that log sensor data as .csv files, to be analysed using a computer later. But this is often very cumbersome, and is not usable in classroom demonstrations.

sensorVector shows a 2d vector of sensors such as accelerometer, gyroscope, magnetic field etc. You can record data and replay it like a video. This enables you to do a wide variety of physics experiments, without needing a computer to analyze.

Students still learning vectors can get a hands on flavour of playing around with vectors in real life..... Measure accelerations of your car. Make your phone weightless. Check how a magnetic field dies down. Make your phone a pendulum. Measure centripetal accelration when spinning around.

The app is fully free. On receiving considerable support, it will be released as open source
