Touch with foreign hands: The effect of virtual hand appearance on visual-haptic integration

Hand tracking and haptics are gaining more importance as key technologies of virtual reality (VR) systems. For designing such systems, it is fundamental to understand how the appearance of the virtual hands influences user experience and how the …

Multisensory contributions to spatial perception

This chapter discusses the sensory systems that have been shown to contribute to spatial perception – vestibular, body-based, audition, and vision. We then present how spatial information is typically multisensory and estimates are integrated within …

Perceived compliance in a pinch

Handling a compliant object using a pinch grasp provides sensory information about deformation and resistive force from both index finger and thumb. In this paper, an object with rigid surfaces and composed of two compliant materials fixed on a …

Combination and integration in the perception of visual-haptic compliance information

The compliance of a material can be conveyed through mechanical interactions in a virtual environment and perceived through both visual and haptic cues. We investigated this basic aspect of perception. In two experiments, subjects performed …

New Method to Measure End-to-End Delay of Virtual Reality

A virtual reality (VR) system tracks one or more objects to generate the depiction of a virtual environment from the user's vantage point. No system achieves this instantaneously: changes in the depicted virtual environment are delayed from changes …

Computationally efficient techniques for data-driven haptic rendering

Data-driven haptic rendering requires processing of raw recorded signals, which leads to high computational effort for large datasets. To achieve real-time performance, one possibility is to reduce the parameter space of the employed interpolation …
