Virtual Hand with Ambiguous Movement between the Self and Other Origin: Sense of Ownership and 'Other-Produced' Agency

While previous research on bodily self-consciousness assumed that self- and other-origin movements were perceptually distinguishable, this protocol allows them to be ambiguous on a virtual hand with unintentional slight movements. This enables us to observe one’s experience formed by SoO and other-produced SoA, rather than the absence of SoA.

Estimation of Contact Regions Between Hands and Objects During Human Multi-Digit Grasping

When we grasp an object, multiple regions of the fingers and hand typically make contact with the object's surface. Reconstructing such contact regions is challenging. Here, we present a method for approximately estimating the contact regions by combining marker-based motion capture with existing deep learning-based hand mesh reconstruction.

The Rubber Hand Illusion

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Reaching for objects, walking without hitting obstacles, landing on a chair as you sit (instead of falling to the floor), these and all our physical actions depend on an ability to perceive our own bodies in space, to know where our limbs are relative to one another and relative to the rest of the world. One way that the human brain encodes this information is called proprioception, the brain relies on its own control and feedback...
FAQs
Control begins with a planned action in the brain, followed by signals sent through motor neurons to muscles that move the joints. Sensory feedback then informs the nervous system about the hand’s current state, allowing force, position, and timing to be adjusted while the action continues. This feedback-based organization supports accurate, coordinated behavior rather than a single fixed command.
Sensory signals from the skin, muscles, and tendons provide ongoing information during an action. The nervous system uses this information to regulate how much force the muscles produce, where the hand and joints are positioned, and when adjustments should occur. Because feedback operates throughout the movement, it helps coordinate behavior as conditions change rather than relying only on the initial motor plan.
Force, position, and timing describe complementary aspects of how a movement is organized. Force concerns muscular output, position concerns the arrangement of the hand and joints, and timing concerns when actions and adjustments occur. Examining these features together helps researchers investigate coordination and motor control, including how the nervous system links planned actions with sensory feedback.
Analysis of hand movements can provide insight into motor control, coordination, learning, and nonverbal communication. These actions connect physical movement with how people interact with their environment and communicate without words. In behavioral research, examining the organization and adjustment of movements therefore helps relate nervous-system control to observable patterns of action and interaction.
Hand movements can support clinical assessment when nerve injury, stroke, or another neurological disorder affects movement. Observing how actions are planned, coordinated, or adjusted may help characterize movement-related difficulties. Their behavioral relevance makes these movements useful for connecting changes in motor performance with conditions that influence the nervous system.
Research on hand movements supports rehabilitation by clarifying the motor control and coordination processes that may be affected after nerve injury, stroke, or other neurological disorders. Information about force, position, and timing provides relevant movement features for clinical consideration. This connection between behavioral observation and motor function helps place hand movement within recovery-focused research and practice.
