Calling All Dentists
A number of firms produce video headsets aka head-mounted displays--goggles that create a virtual screen in front of the wearer. If my dentist provided me with one, connected to a computer, possibly my own laptop, with a mouse or equivalent where I could reach it, perhaps even a keyboard in my lap… .
I could browse the internet, play a video game, watch a DVD. The headset would be well above the dentist's working area, the controls well below. No longer would I tax the patience of dentist and technician trying to hold a magazine or PDA--I read books on PDA--where it could be seen but would not be in the way. No longer would they tax my patience with long procedures.
And if it did hurt a little, I might not notice--depending on just how absorbing the video game, or Usenet argument, happened to be.
