IEEE Transactions on Haptics
|June 30, 2026
Summary
In virtual reality (VR), tactile stimuli felt longer than visual stimuli of the same duration. This finding, related to temporal judgments, offers insights for VR application design.
Area of Science:
- Cognitive Psychology
- Human-Computer Interaction
- Neuroscience
Background:
- Temporal judgments differ across sensory modalities.
- Auditory stimuli are often perceived as longer than visual stimuli.
- Research comparing tactile and visual duration perception, especially in virtual reality (VR), is limited.
Purpose of the Study:
- To compare visual and tactile duration judgments within a virtual reality (VR) environment.
- To investigate how the unique characteristics of VR influence cross-modal temporal perception.
- To assess the applicability of the Scalar Expectancy Theory (SET) to VR-based timing tasks.
Main Methods:
- Participants engaged in a cross-modal comparison task in VR.
- Tactile stimuli were delivered to the participant's hands.
- Visual stimuli were presented on virtual hand representations in VR.
- Judgments were made on whether tactile stimuli were longer than visual stimuli.
Main Results:
- Tactile stimuli were consistently perceived as longer than visual stimuli of identical duration.
- Behavioral data aligned with the Scalar Expectancy Theory (SET) of timing.
- Visual duration judgments exhibited greater variability compared to tactile judgments.
Conclusions:
- Duration judgments in VR are influenced by factors like saliency contrast and VR-specific conditions.
- Tactile perception may be more stable than visual perception for temporal judgments in VR.
- Findings can inform the design and optimization of virtual reality applications for enhanced user experience.

Vibrating Concrete
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...
Perception of Sound Waves
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 frequency...

Virtual Work
The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

IR Spectrum Peak Splitting: Symmetric vs Asymmetric Vibrations
Identical bonds within a polyatomic group can stretch symmetrically (in-phase) or asymmetrically (out-of-phase). Similar to hydrogen bonding, these vibrations also influence the shape of the IR peak. Generally, asymmetric stretching frequencies are higher than symmetric stretching frequencies. For example, primary amines exhibit two distinct IR peaks between 3300–3500 cm−1 corresponding to the symmetric and asymmetric N-H stretching, while secondary amines exhibit a single stretching vibration...
Depth Perception and Spatial Vision
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.
Virtual Work for a System of Connected Rigid Bodies
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.
