I do a lot of DC work. I prefer ADC whenever possible. Take, for example, a fuel delivery person. I know which fueling station is being serviced because of the GPS coordinates when the truck pump is switched on. I have level sensors in each tank. I know the level at turn on and at turn off. It's a simple matter of comparison to know how much fuel was dispensed at each delivery. I know arrival and departure times from Geo-fencing. What is hard to determine is what fuel grade got pumped into which station tank. I still have a manual data entry screen on the truck OBC to help out the driver when her sensor net fouls up.

We have been working with RFID for a while in warehouse environments. I can tell where every forklift is in a warehouse. If I tag all the boxes and pallets I can then sense what is being picked up and put down. The backup to RFID is barcoding and the backup to that is keying. I want to play with VR in warehousing.

I used to do software for dentists. Periodontal charting is a great candidate for VR. There are only 33 teeth with 6 pockets each. The depth is on a limited scale. The readings are taken in a specific order.
