Make a list of pointing devices. Consider some new or futuristic alternatives.

What will be an ideal response?

See below (Box 10.1 below from DTUI6). The point here is that there are numerous pointing devices, some used every day and some with very specialized applications, e.g. accessibility devices for those with physical challenges, e.g. eye-tracking for user experience testing. Ask the class for any present or futuristic pointing devices that may not even be included on this list. This author has seen a device where a physically-challenged individual (paralyzed from the neck down) can use a device to drive a motorized wheelchair with tongue movements.
