The Immersive VR Self: Performance, Embodiment and Presence in Immersive Virtual Reality Environments

Book chapter from A Networked Self and Human Augmentics, AI, Sentience

Virtual avatars are a common way to present oneself in online social interactions. From cartoonish emoticons to hyper-realistic humanoids, these online representations help us portray a certain image to our respective audiences.

Speech Communication through the Skin: Design of Learning Protocols and Initial Findings

Computer Human Interaction (CHI)

This study reports the design and testing of learning protocols with a system that translates English phonemes to haptic stimulation patterns (haptic symbols).

Feeling Speech on the Arm

Computer Human Interaction (CHI)

In this paper, we introduce a transcutaneous language communication (TLC) system that transmits a tactile representation of spoken or written language to the arm.

Towards Pleasant Touch: Vibrotactile Grids for Social Touch Interactions

Computer Human Interaction (CHI)

In this paper, we realize a wearable tactile device that delivers smooth pleasant strokes, those resemble of caressing and calming sensations, on the forearm.

Communication Behavior in Embodied Virtual Reality

Human Computer Interaction Conference (CHI)

To investigate communication behavior with embodied virtual reality onto an avatar in a virtual 3D environment, we had 30 dyads complete two tasks using a shared visual workspace: negotiating an apartment layout and placing model furniture on an apartment floor plan.

Sparse Head-Related Transfer Function Representation with Spatial Aliasing Cancellation

International Conference on Acoustics, Speech and Signal Processing

In this paper, a new technique to reconstruct high resolution individual HRTFs from sparse measurements is presented. This is achieved by minimizing the spatial aliasing error in the spherical harmonics (SH) representation of the HRTFs, and by incorporating statistics calculated from a set of reference HRTFs, leading to an optimal minimum mean-square error solution.

Design and Analysis of a High-Performance Impedance-Based Hybrid Haptic Interface

Haptics Symposium

This paper describes the design of a novel, high-performance one degree-of-freedom hybrid haptic interface. The interface integrates a particle brake, a Series Elastic Actuator (SEA), and a small DC motor into a single actuator. Unlike existing hybrid designs, the one presented here does not suffer from a significant mismatch between passive and active torque capability.

A Social Haptic Device to Create Continuous Lateral Motion Using Sequential Normal Indentation

IEEE Haptics Symposium (HAPTICS)

This paper presents a device for creating a continuous lateral motion on the arm to mimic a subset of the gestures used in social touch.

Toward Improved Surgical Training: Delivering Smoothness Feedback using Haptic Cues

IEEE Haptics Symposium (HAPTICS)

In this paper, we explore the effectiveness of providing real-time feedback of movement smoothness, a characteristic associated with skilled and coordinated movement, via a vibrotactile cue. Subjects performed a mirror-tracing task that requires coordination and dexterity similar in nature to that required in endovascular surgery.

Fast Gaze-Contingent Optimal Decompositions for Multifocal Displays

SIGGRAPH ASIA

Our goal is to enable interactive optimal decomposition algorithms capable of driving a vergence- and accommodation-tracked multifocal testbed. Ultimately, such a testbed is necessary to establish the requirements for the practical use of multifocal displays, in terms of computational demand and hardware accuracy. To this end, we present an efficient algorithm for optimal decompositions, incorporating insights from vision science.
