touch sensor
"The Touch Sensor is like the skin of of your robot! It lets your robot react when touched. There are three settings for the Touch Sensors to react to. Bumped, Pressed, and Released."
"Your finger is like the thundercloud and the ITO layer in the touch sensor is like the ground in a storm. Your finger becomes a component in the circuit. In a sense, you have become a part of the phone."
"The touch sensor is like a bumper; it enables the robot to detect press-and-release events."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
