Augmenting Perceived Softness of Haptic Proxy Objects Through Transient Vibration and Visuo-Haptic Illusion in
IEEE Transactions on Visualization and Computer Graphics
|August 4, 2020
Summary
This study explores how active transient vibrations and visuo-haptic illusions enhance the perceived softness of virtual objects. Combining these methods effectively allows users to experience varied softness levels in haptic interactions.
Area of Science:
- Human-Computer Interaction
- Haptics
- Virtual Reality
Background:
- Perceived softness is crucial for realistic haptic interactions.
- Existing methods for simulating softness in virtual reality have limitations.
Purpose of the Study:
- To investigate the individual and combined effects of active transient vibration and visuo-haptic illusion on perceived object softness.
- To develop a system that augments the perceived softness of haptic proxy objects.
Main Methods:
- A handheld device was developed using a voice coil actuator for fingertip vibrations and a force sensor for visuo-haptic feedback.
- Three user studies were conducted to evaluate vibrotactile effects, visuo-haptic illusions, and their combination.
Main Results:
- Active transient vibrations were found to intuitively alter perceived softness and vary based on object material.
- Both active transient vibration and visuo-haptic illusions significantly influenced perceived softness, with the latter being dominant.
- The combined approach effectively enabled users to perceive various levels of softness.
Conclusions:
- Combining active transient vibrations with visuo-haptic illusions offers a powerful method for enhancing perceived softness in haptic interactions.
- This research contributes to more immersive and realistic virtual reality experiences through advanced haptic feedback.

01:19Vibrating Concrete
290
Mechanical vibrators are instrumental in compacting newly poured concrete within formwork and around reinforcements. This process is essential to eliminate trapped air pockets and establish a dense concrete mass. One widely used method is vibrating by internal vibrators, often referred to as a poker vibrator or immersion vibrator. It is rapidly inserted through the full depth of the freshly laid concrete and slightly extends into the layer below it (which remains in a plastic state). Consistent...

01:01Perception of Sound Waves
5.3K
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...

01:06Virtual Work for a System of Connected Rigid Bodies
631
Virtual work is a powerful method used to solve problems involving several connected rigid bodies. When the system is in equilibrium, virtual work is zero. This allows the calculation of the resulting forces when a system undergoes a virtual displacement. When attempting to analyze such a system, first, use a free-body diagram, where an independent coordinate represents the configuration of the links, and mark its deflected position resulting from the positive virtual displacement.

01:27Tactile and Chemical Senses
563
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.

01:24Facial Feedback Hypothesis
447
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...
