A common cause in the phenomenological and sensorimotor correlates of body ownership

International Multisensory Research Forum

The feeling that our limbs belong to our body is at the core of bodily self-consciousness. Over the years, limb ownership has been assessed through several types of measurements, including questionnaires and sensorimotor tasks assessing the perceived location of the hand with a visual-proprioceptive conflict.

A Comparative Study of Phoneme- and Word-Based Learning of English Words Presented to the Skin

Eurohaptics

Past research has demonstrated that speech communication on the skin is entirely achievable. However, there is still no definitive conclusion on the best training method that minimizes the time it takes for users to reach a prescribed performance level with a speech communication device. The present study reports the design and testing of two learning approaches with a system that translates English phonemes to haptic stimulation patterns (haptic symbols).

Improving Perception Accuracy with Multi-sensory Haptic Cue Delivery

Eurohaptics

This paper presents a novel, wearable, and multi-sensory haptic feedback system intended to support the transmission of large sets of haptic cues that are accurately perceived by the human user. Previous devices have focused on the optimization of haptic cue transmission using a single modality and have typically employed arrays of haptic tactile actuators to maximize information throughput to a user.

Efficient Evaluation of Coding Strategies for Transcutaneous Language Communication

Eurohaptics 2018

Communication of natural language via the skin has seen renewed interest with the advent of mobile devices and wearable technology. Efficient evaluation of candidate haptic encoding algorithms remains a significant challenge. We present 4 algorithms along with our methods for evaluation, which are based on discriminability, learnability, and generalizability. Advantageously, mastery of an extensive vocabulary is not required.

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.

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.
