TBH I think you are underestimating the practicality of it. If we are co-working or co-inhabiting with non-static entities, this becomes a much bigger concern. There is a reason industrial robots are generally in safety cages, with rapid shutdown any time the safety boundary is crossed by a human. Option 1
- my home robot makes a sudden movement, catching me off guard, and smacking me across the shins (or worse). Option 2
- my robot loudly announces "warning, moving to the left in 5, 4, 3, 2, 1", which drives me insane after a few days. Option 3
- my robot taps into a million years of non-verbal communication that humans have evolved, and indicates what it is about to do both with more subtle audible and physical cues. PS: regarding "display attention" - trivial example, "hey assistant, remind me to do X on Sunday" - option 1: no attention display, I have no idea whether my request has been recorded - option 2: verbal or auditory or physical cue that assistant is listening, and a cue to confirm that the request was processed successfully. |
