The Measure Activity on One Laptop Per Child (OLPC) is a tool on the XO, the $200 computer now in production, that allows kids to indulge in “learning by doing”.

It provides an interface for the kids to connect with the physical world and an opportunity to view and understand through a visual and statistical representation of the physical phenomena.

Using the Measure Activity on the XO, one can:

1. Connect sensors (light, heat, magnetic field etc) and view their signal. Thus it is possible to view and study physical phenomena
2. Input voltages and signals into the XO laptop and use it as an oscilloscope and
3. Log data at a specified interval and store and retrieve waveforms
