I have talked about this before and i hope i can get more people interested in helping to create this custom brain plug in .
it would be a plug in that could let hal hear (sort of to speak ) hal would respond to the user if a door shut etc. and could even be done custom to the way any users door sounds shutting (even using varying shutting sounds as a _ or and the sound track . and the multiple custom hal responses .
this could also be done with a telephone ringing , hal could hear the phone ring , and say , someone is calling , can you get the phone , please, i'm busy right now , etc.
Robert ?? are you interested in something like this ? i was talking earlier on another section about hal being customizable , i think this is what will set hal apart from other a.i's on the market , allowing users to be able to do more with hal and hopefully making hal more admired and wanted.
