Point and draw Devices. A pointing device is an input interface that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer. Movements of the pointing device are echoed on the screen by movements of the pointer (or cursor) and other visual changes. A pointing device is an input interface that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer.

they probably would use a sonar which is a device that bounces sound waves off under water objects and then records the echoes of these sound waves. =]
Input. You draw on it, the movements are converted into digital data which goes INTO the computer. The answers are normally the logical ones.

it is creep meter
A laser-rang device works by using a laser beam to find horizontal fault movements. It can also use the laser beam to travel to a reflector and then back. Thus, the device can detect any change in distance to the reflector.
four instruments that are used to detect faults are: creep meters, laser-ranging devices, tiltmeters, and satellites. how they work: a creep meter uses a wire stretched across a fault to measure sideways movement the ground. a laser-ranging device uses a laser beam bounced off a reflector to detect any fault movements
