I read one paper relative to my project.
The title is “Robot programming through augmented trajectories in augmented reality“.
This paper uses a mixed reality head-mounted display which is Microsoft Hololens and a 7-DOF robot arm. They designed an augmented reality robotic interface with four interactive functions to ease the robot programming task: 1) Trajectory specification. 2) Virtual previews of robot motion. 3) Visualization of robot parameters. 4) Online reprogramming during simulation and execution.
