Short answer

In designing interactive systems involving avatars or robots, consider how visual actions can be used to evoke corresponding tactile sensations in the user, thereby increasing engagement and perceived presence.

Method: Experimental study with illusion induction
Sample: Not explicitly stated, but implied to be multiple participants across two studies.
Evidence: Moderate effect

Observing a robot avatar interact with an object can lead users to perceive tactile sensations in their own hands, even without direct physical contact. This human factors research insight is drawn from a 2017 study published in Journal of Computer-Mediated Communication. Using Experimental study with illusion induction with Not explicitly stated, but implied to be multiple participants across two studies., researchers explored how this design variable affects real-world outcomes. The key design takeaway: In designing interactive systems involving avatars or robots, consider how visual actions can be used to evoke corresponding tactile sensations in the user, thereby increasing engagement and perceived presence.

Key Findings

01Approximately 60% of participants reported experiencing haptic sensations in their real hand when observing the robot avatar's hand touch an object.
02This haptic illusion can occur with non-anthropomorphic limbs and relies solely on visual feedback.

Application

Design takeaway

How to apply

When designing a virtual reality experience where a user's avatar interacts with virtual objects, ensure the visual representation of the interaction is clear and direct, as this can lead to the user feeling the touch themselves.

Project actions

01When designing a user interface or a robotic system, think about how visual feedback can be used to create a sense of touch for the user.
02Consider how to make the visual representation of touch as realistic as possible to enhance the user's experience.

Method & Evidence

AimTo investigate whether users experience haptic sensations in their real hand when observing a humanoid robot avatar perform a tactile action, and to quantify this effect.

MethodExperimental study with illusion induction

ProcedureParticipants observed a humanoid robot avatar through a screen. In specific conditions, the robot avatar's hand was shown touching an object (e.g., a curtain). Participants were then asked to report any tactile sensations they experienced in their own hands.

SampleNot explicitly stated, but implied to be multiple participants across two studies.

ContextHuman-robot interaction, virtual reality, mediated embodiment

Variables

IVVisual feedback of robot avatar touching an object.

DVReported haptic sensation in the user's real hand.

CVType of avatar limb, type of object touched, visual display quality.

Strengths & Limitations

Strengths

+Demonstrates a novel haptic illusion.
+Highlights the role of visual feedback in sensory perception.

Limitations

The effect might vary depending on the individual's susceptibility to illusions, the quality of the visual feedback, and the specific context of the interaction.

Reliability & validity

Reliability could be assessed by repeating the experiment with the same participants. Validity could be enhanced by using objective measures if possible, though subjective reporting is inherent to this phenomenon.

Think critically

To what extent can this visual-tactile illusion be intentionally manipulated to enhance or even mislead user perception in different design contexts?

Design Principles

"Visual-tactile congruence in mediated environments can induce illusory haptic feedback."

This phenomenon highlights the powerful connection between visual perception and our sense of touch, particularly in mediated environments. Understanding this illusion is crucial for designing more immersive and intuitive human-robot interactions and virtual experiences.

What This Means for Your Design

If you see a robot hand touch something on a screen, you might feel like your own hand is being touched, even if it's not.

How to use in your project

1.This research can be used to justify design choices related to visual feedback in interactive systems, explaining how it can contribute to a more immersive user experience.

Paragraph starter

The research by Aymerich-Franch et al. (2017) demonstrates that visual interaction with a robot avatar can induce phantom haptic sensations in users. This suggests that carefully designed visual feedback in interactive systems can leverage the brain's tendency to link sight and touch, thereby enhancing user immersion and the perceived realism of mediated experiences.
