Determining natural arm configuration along a reaching trajectory
Experimental Brain Research, 2004Owing to the flexibility and redundancy of neuromuscular and skeletal systems, humans can trace the same hand trajectory in space with various arm configurations. However, the joint trajectories of typical unrestrained movements tend to be consistent both within and across subjects.

Interactive Tabletop Arm Reaching Exercise
Proceedings of the Thirteenth International Conference on Tangible, Embedded, and Embodied Interaction, 2019In order to regain motor control, stroke patients should do various exercises that target at specific body functions. During daily exercising, they need assistance from either therapists or caregivers in setting tasks, providing feedback and other activities.

ARM and Rovsim: extending our reach
Industrial Robot: An International Journal, 1999This paper describes the development of the ARM System, an advanced subsea manipulator for weld inspection. ARM uses an advanced man‐machine interface and provides robotic control of the manipulator using techniques developed in factory robots. A more advanced robotic control system, Polecat, is currently being developed using experience gained from ...

Virtual arm׳s reach influences perceived distances but only after experience reaching
Neuropsychologia, 2015Considerable empirical evidence has shown influences of the action capabilities of the body on the perception of sizes and distances. Generally, as one's action capabilities increase, the perception of the relevant distance (over which the action is to be performed) decreases and vice versa. As a consequence, it has been proposed that the body's action

Arm Trajectory Modifications During Reaching Towards Visual Targets
Journal of Cognitive Neuroscience, 1991Abstract In this paper we study the question of how an aimed arm movement is modified in response to a sudden change in target location occurring during the reaction or movement time. Earlier monkey and human studies demonstrated that aimed arm movements can be elicited in quick succession, without appreciable delays in responding to the

Head, arm and trunk coordination during reaching in children
Experimental Brain Research, 2008During postural and locomotor tasks, the orientation of the head with respect to space is maintained in order to serve as an egocentric reference value for maintaining balance. In young children during locomotor tasks, task difficulty determines the coordination of movements between head-trunk segments: the more difficult the task, the more the child ...

Do Arm Postures Vary With the Speed of Reaching?
Journal of Neurophysiology, 1999Do arm postures vary with the speed of reaching? For reaching movements in one plane, the hand has been observed to follow a similar path regardless of speed. Recent work on the control of more complex reaching movements raises the question of whether a similar “speed invariance” also holds for the additional degrees of freedom.

Optimal trajectory formation of constrained human arm reaching movements
Biological Cybernetics, 2004Opening a door, turning a steering wheel, and rotating a coffee mill are typical examples of human movements that are constrained by the physical environment. The constraints decrease the mobility of the human arm and lead to redundancy in the distribution of actuator forces (either joint torques or muscle forces).
