ComMotion Shield for omni and mecanum wheel robots

After building my first omni wheel robot I realized how difficult it can be to monitor 4 encoders and drive 4 motors so I designed the ComMotion shield. As the name suggest the shield is designed for motion control but as I ended up with 2 spare serial ports I decided to add communications abilities to the shield hence the name ComMotion.

Detecting someone is using a Desk. [Sensor Advice]

I want to do a system or robot that detects someone is using a desk. My question is which sensor or type of detection you would recommend me to use to allow to know someone is using a desk.

 

My choice are:

-Using an LED and LDR under the table if a person sits, it will detect. (If they wear a black cloth maybe it will not reflect back).

-Use an RFID tag, the person that uses the desk's touch with a tag.

-Distance sensor, in ebay this sensor is very cheap.

 

Not Automatic choice
