The association of color and sound helps human cognition through a synergetic effect like intersensory facilitation. Although soft human-machine interfaces (HMIs) providing unisensory expression have been widely developed, achieving synchronized optic and acoustic expression in one device system has been relatively less explored. It is because their operating principles are different in terms of materials, and implementation has mainly been attempted through structural approaches.

Article Synopsis
- Typical VR handheld controllers don’t change shape or size based on the objects they represent, leading to a mismatch in user experience.
- The paper explores a length perception model that incorporates the moment of inertia (MOI) and diameter of an object, aiming to create a shape-changing interface for better interaction.
- Two experiments were conducted: one to measure the perceived lengths of objects and another to validate the perception model by matching visual and haptic rods, ultimately contributing to design algorithms that enhance sensory cues in VR.
