Cutting the Cord: Soft Haptic Devices without a Pressure Source

International Conference on Soft Robotics (RoboSoft)

We present a class of pneumatic haptic devices that use the input motion from a user to pump fluid in a closed pneumatic circuit, meaning that the pneumatic devices require no external pressure supply.

Evaluation of real-time sound propagation engines in a virtual reality framework

AES International Conference on Immersive and Interactive Audio

Sound propagation in an enclosed space is a combination of several wave phenomena, such as direct sound, specular reflections, scattering, diffraction, or air absorption, among others. Achieving realistic and immersive audio in games and virtual reality (VR) requires real-time modeling of these phenomena.

The Effect of Hand Size and Interaction Modality on the Virtual Hand Illusion

IEEE Conference on Virtual Reality

In this paper, we consider how concepts related to the virtual hand illusion, user experience, and task efficiency are influenced by variations between the size of a user’s actual hand and their avatar’s hand.

DeepFocus: Learned Image Synthesis for Computational Displays

ACM SIGGRAPH Asia 2018

In this paper, we introduce DeepFocus, a generic, end-to-end convolutional neural network designed to efficiently solve the full range of computational tasks for accommodation-supporting HMDs. This network is demonstrated to accurately synthesize defocus blur, focal stacks, multilayer decompositions, and multiview imagery using only commonly available RGB-D images, enabling real-time, near-correct depictions of retinal blur with a broad set of accommodation-supporting HMDs.
