OBJECTIVE To develop a model for human performance in combined translational and rotational movements based on Fitts' law. BACKGROUND Fitts' law has been successfully applied to translational movements in the past, providing generalization beyond a specific task as well as performance predictions. For movements involving both translations and rotations,(More)
— An approach for adaptive shared control of an assistive manipulator is presented. A set of distributed collision and proximity sensors is used to aid in limiting collisions during direct control by the disabled user. Artificial neural networks adapt the use of the proximity sensors online, which limits movements in the direction of an obstacle before a(More)
—The work described here explores an approach for learning online the sensorimotor interaction that a robot has with the world, and the higher-level concepts grounded in this interaction. A type of spatiotemporal connectionist neural network was implemented. In consists of a set of time-delayed input layers which receive both low-level sensor inputs and(More)
Assistive robotics HRI has a number of important characteristics that distinguishes it from other forms of HRI. This includes the need for both high flexibility, safety and reliability in controlling the robotic system. Approaching the system as a human-robot binomial, with the user and the robot acting in a closed-loop, may be beneficial to understanding(More)
