Free HCI for you

One example of HCI is the automatic sliding door.  I will speak of its traits in general terms, but as with any technology a standard can have customizations for enhancement.  The automatic sliding door can be found in different environments (personal, medical, business, security).  Because of its motion detection trait, it becomes a universal type of device-opening for those with their hands full, for those with visual impairments and physical disabilities.  For example, it is large enough for a wheelchair to go through with ease and enough space.  It is definitely usable and useful to everyone, as it requires nothing from the user, but provides the user with a service.  Also, good automatic doors will have numerous security and safety features.  A drawback to this technology could be that it malfunctions or does not open.  This could make the user lose a few minutes of his/her time, but the door would eventually be opened the old fashioned way, due to manual features.  However, in an emergency situation, those few minutes could be crucial.  Overall, it's a device that makes our lives a little easier.  Just think of all you could do with that extra second!
