Dual Body Sensation: Effects of Visio-Tactile Presentation Methods in Parallel Agent Control
IEEE Transactions on Visualization and Computer Graphics
|March 30, 2026
Summary
Dual Body Sensation (DBS) allows operators to control two robots simultaneously. Unified tactile feedback significantly enhanced this distributed embodiment, improving user experience in multi-agent systems.
Area of Science:
- Human-Robot Interaction
- Embodied Cognition
- Virtual Reality
Background:
- Controlling multiple agents in parallel is crucial for applications like remote collaboration and telepresence.
- Limited empirical research exists on distributed embodiment, especially with avatars in distinct environments.
Purpose of the Study:
- To introduce and investigate the cognitive feasibility of Dual Body Sensation (DBS).
- DBS describes an operator's simultaneous embodiment of two independent robots in separate environments.
Main Methods:
- A within-subject experiment was conducted with a 2x3 factorial design.
- Independent variables included visual presentation (independent vs. superimposed view) and tactile presentation (none, bilateral, unified).
Main Results:
- Dual Body Sensation (DBS) was achieved across all experimental conditions.
- Unified tactile feedback significantly enhanced DBS.
- Superimposed view and unified tactile conditions boosted body ownership and agency.
- Superimposed view reduced cybersickness and cognitive load.
Conclusions:
- Empirical support for the cognitive feasibility of Dual Body Sensation (DBS) was established.
- Findings inform the design of advanced multi-agent interaction systems.
- Future systems can better support distributed control and awareness across multiple agents.

Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...
