Infrared sensor for calling an elevator

 Use infrared door opening sensors to call an elevator automatically as you approach it's doors

(The most useful only for the first and the highest floors of private apartments or in low-traffic areas to avoid high rate of false positives if people are just passing nearby the elevator without intending to use it.)

       (-) I'd rather deliberately push a button than deal with the false positives and negatives of an infrared sensor.

       [-] There is just something that is intrinsically authentic about pushing that button to call the elevator.

       Can you imagine the resultant vandalism after an elevator car full of stressed out executives tries to go to the ground floor from the top floor of a busy office building? With false-positive elevator stops on every second floor from people wandering past the elevators?   

       Also, and possibly most problematic, how does the elevator know you want to go up or down???

       // how does the elevator know you want to go up or down?// I guess you figure that out once you get on.

       Are you going to be allowed to eviscerate the people that stop you on floors 20, 19, 18, 16, 14, 12, 10, 8, 6, 4, and 2 that want to go up, when you're trying to go from 21 to ground?

       Have a standardized dance for 'UP' and one for 'DOWN,' with the sensor able to detect whether your hand is pointing to the air or the ground. Something out of Saturday Night Fever should do nicely. Not certain which way John Travolta would end up, nor am I certain how bad already horrid disco would become once translated into Muzak. But it could keep criminals away. Usually criminals have better slightly music taste.   

       I'd certainly brighten my day to see hurried executives and women with babies trying to dance in front of an elevator. Come to think of it, this would be an excellent Candid Camera prank.
