Control of fingertip forces in object lifting and weight perception
When picking up an object, the forces applied by the fingertips have to be scaled to the weight of the object. Object information, such as size or material, can be used to make a motor plan. If the initially planned forces are incorrect, online sensory feedback loops can be used to correct the movement. This project investigates how visual and haptic information is used to plan and control fingertip forces in object lifting and how this interacts with how you perceive the weight of this object. To do this, I use differently weighted cubes, force sensors and a virtual reality environment.
