Talk to it nicely and it begins to purr. Yell at it and it starts getting angry at you. The clean version doesn't use swear words.
A visually controlled version reacts with sounds to your movement, waving a fist at it, can get it going real bad. Just smiling and waving could make it very friendly.
Of course the advanced version allows you to set the accent.-- pashute, Dec 13 2012 Wiki: Sony AIBO http://en.wikipedia.org/wiki/AIBOI'm not sure whether the thing you're imagining in your idea just lives in a PC, or is a manifest "thing", but the Sony AIBO was touted as having a certain amount of "mood-recognition" i.e. behavioural changes based on recognition of noises and gestures made by its owner. [zen_tom, Dec 13 2012] I think the Sony Aibo did this - which reminds me, I forestalled purchasing one of those back in 2005 in anticipation of the very exciting-looking Qrio - which dissapeared off the face of the earth - I wonder what happened to that project?-- zen_tom, Dec 13 2012 No this is under computer:game. I meant it for the PC or smartphone, so that everybody instantly has it available. It will be the next scream.-- pashute, Dec 13 2012 random, halfbakery
