In addition to labor, technology can also help us with the information work involved in a task.

Of course, thermometers give a user some facts to work with in managing the heat of a space.

What’s the actual temperature here? Is it just me who’s feeling cold? What temperature is the thermostat set to? Is it currently putting out heat or not? Is it even on?

These metrical tools give us facts to help us make decisions while performing a task.

More sophisticated technologies can begin to understand the rules of how a task should be performed, and let the user know when good form is being violated or thresholds crossed. These corrective tools help them understand what’s going on and correct course if they’re off track. If a user sets a thermometer to a temperature higher than it could actually attain, for instance, it could immediately provide this feedback and suggest additional measures that could be taken. This would be corrective.
