Well you can only interact with most tools in one single orientation, like with the blowdryer always pointing left so you have to turn the card 180 degrees to point it to the right. You can't point the blowdyer forwards or backwards, for instance. So it's possible they'd allow you to have more freedom and more range of movement with some tools, if they're designed to take advantage of it. You'd also have a trigger, for grabbing and releasing things, like tossing a ball. They could have him chase a laser pointer- the possibilities are only limited by their imaginations, and they can always look at how people interact with real pets for inspiration. They could have a leash where you walk your pet through the city, and he gets distracted, pees on fire hydrants, poops in the neighbors' lawns, and you have to tug in a certain direction to get him back on track, squeeze the trigger to let out more slack, etc.
I'm sure they'll think of plenty more uses for it, since they're paid to sit in a room and brainstorm whereas I just sat here for 5 minutes with my mind also on other things.
