A Tactile Computer Mouse for the Display of Surface Material Properties

Area of Science:

• Human-Computer Interaction
• Haptics
• Material Science

Background:

• Traditional computer mice lack tactile feedback capabilities.
• Accurate tactile perception is crucial for material identification and interaction.
• Existing methods for rendering tactile properties are limited.

Purpose of the Study:

• To develop a novel input/output device, the Tactile Computer Mouse (TCM), for displaying tactile properties of surface materials.
• To enable users to perceive and differentiate virtual surface materials through tactile cues.
• To validate the TCM's effectiveness in rendering key tactile dimensions.

Main Methods:

• Designed a Tactile Computer Mouse (TCM) with actuators to generate tactile cues.
• Developed data acquisition and parametric representation methods for surface materials.
• Conducted subjective experiments to assess tactile property perception and material matching.
• Evaluated TCM performance in rendering hardness, friction, warmth, and roughness (microscopic and macroscopic).

Main Results:

• The TCM successfully displays five fundamental tactile dimensions: hardness, friction, warmth, microscopic roughness, and macroscopic roughness.
• Participants achieved an 89.6% recognition rate for ten different virtual materials presented via the TCM.
• The TCM preserves standard computer mouse interaction functionalities.

Conclusions:

• The developed Tactile Computer Mouse (TCM) effectively renders a wide range of tactile surface material properties.
• The TCM shows significant potential for enhancing virtual reality experiences and remote material interaction.
• This technology advances the field of haptic feedback for digital content creation and consumption.
