Automatic sliding doors are smart Star Trek

Automatic sliding doors that we are aware of Star Trek is much more intelligent than the automatic sliding doors that we are aware of the reality of life. In Star Trek, the doors seem to know when you want to go through the figures to her, and she did not open by accident when someone is just walking. In addition, they have managed to never be in the way when a character is running at full speed towards them (you try it at the mall and see what happens). Is it really too much to ask for automatic to have this kind of intelligence doors? It's not like we're asking for the carrier. Researchers now have robots (finally) made ​​it happen.

There are two major improvements that take place here. First, the door is open only to persons who intend to use it. And secondly, is determined by the speed, width and time to open the door on the basis of observations of position, speed and the number of people walking. Estimates of the door when you arrive, and its opening hours so that you have just finished opening the same as you get there. If you are in a hurry, cranks up the speed of the opening of the door to make sure it is out of your way in a timely manner. It also opens wider to accommodate more people at a time when it should. The door may not be able to know whether to keep itself closed when you make a break just before to great effect, but otherwise, this is about as smart as Star Trek and the door.

The secret of this intelligence is not a secret: the door has a dedicated sensor fantasy (time of flight 3D laser scanner) as well as algorithms to detect people, and keep track of their movement, and to educated guesses about whether or not you aim the door. Unusually for a document of this type of research, there are some serious consideration in the process. The sensor is designed for use in areas where the ambient lighting from direct sunlight to total darkness (between 0 and 200 000 LX), and the software can compensate for snow and rain, and water on the sensor itself, and interference from other nearby sensors.

This amateur sensor at an additional cost of traditional sensor automatic door. The researchers say that the sensor can add custom they put about $ 1,000 for the cost of the door, which seems a lot. However, the cost of such devices is something that tends to significantly limit during the previous year, so we would like to think that we will be able to discover the doors smart like that without having to live long enough long to see the maiden voyage of the USS Enterprise.
