This paper proposes a multimodal controller that interactively leverages pose and velocity control for teleoperation, designed to address workspace limitations by dynamic workspace reindexing while taking into account operator ergonomics. Dynamic workspace reindexing offers a solution to the limitations of existing approaches, such as scaling and clutching. To ensure operator ergonomics, The Rapid Upper Limb Assessment (RULA) method is used to define an Ergonomic Workspace (EW) within which the operator must remain to maintain an ergonomic posture. Within the boundaries of the EW, non-scaled pose control is used to control the follower, offering intuitive interaction with the remote environment while maintaining good operator ergonomics. Outside the EW boundaries, velocity control is applied, where the velocity of the follower is based on the force exerted by the operator on the leader haptic device, allowing the operator to dynamically reindex the follower workspace. This control mode facilitates coarse positioning of the follower between targets. A proof-of-concept demonstration shows that the proposed controller succesfully addresses workspace limitations by dynamically reindexing the follower's workspace towards target objects. Furthermore, it is shown that the controller consistently maintains good operator ergonomics during interaction with the remote environment, thereby making it a suitable option for prolonged teleoperation tasks.
