Modifiable motion graphics for capturing sensations

Area of Science:

• Neuroscience
• Psychophysics
• Human-Computer Interaction

Background:

• Embodied sensory experiences, like pain, are complex and challenging to quantify.
• Visualizing subjective sensations is crucial for research, clinical diagnosis, and therapeutic interventions.

Purpose of the Study:

• To investigate the relationship between embodied sensory perception (tingling) and its visual translation using modifiable motion graphics.
• To assess if individuals can visually represent tactile sensations through interactive digital tools.

Main Methods:

• Developed custom software for real-time modification of motion graphics depicting pain descriptors.
• Utilized electrical stimulation to evoke tingling sensations in 34 participants.
• Participants visually mapped evoked sensations and adjusted motion graphic parameters (speed, density) to match their perception.

Main Results:

• Increased electrical stimulation intensity led to larger perceived areas, higher motion graphic density, and greater perceived intensity.
• Motion graphic density, not speed, significantly correlated with perceived intensity and stimulation levels.
• The descriptor 'tingling' was predominantly chosen at moderate stimulation levels, with 'stabbing' appearing at higher intensities.

Conclusions:

• Motion graphics can effectively visualize embodied sensations like tingling, with density being a key parameter.
• Findings suggest a potential for consistent visual representation of sensory experiences across individuals.
• This research opens avenues for using psychophysics to explore and quantify sensory experiences in various applications.
