| Movement & Position - Control | ||||||||||||||
| Move Seat IncrementallyContinuously | Move the identified seat in the specified direction. When a user commands a seat in a certain direction, it will incrementallymove in that direction until the value is changed. The change (e.g. stop) could come from the user or a hardware limit. |
|
| One request/trigger moves one increment. | N/A | Move Seat to Specified Position | Set the seat position for the identified seat. This is entire seat position forward, back, up down. |
