The Effect of Computer-Generated Descriptions on Photo-Sharing Experiences of People with Visual Impairments

Conference on Computer-Supported Cooperative Work and Social Computing (CSCW)

Like sighted people, visually impaired people want to share photographs on social networking services, but find it difficult to identify and select photos from their albums. We aimed to address this problem by incorporating state-of-the-art computer-generated descriptions into Facebook’s photo-sharing feature.

Online Optical Marker-based Hand Tracking with Deep Labels

Special Interest Group on Computer Graphics and Interactive Techniques (SIGGRAPH)

We propose a technique that frames the labeling problem as a keypoint regression problem conducive to a solution using convolutional neural networks.

“I’m Never Happy with What I Write”: Challenges and Strategies of People with Dyslexia on Social Media

International Conference on Web and Social Media

This work studies the experiences, challenges, and strategies of people with dyslexia when using social media. We interviewed 11 people with dyslexia to understand their general experiences with reading and writing content on Facebook. The interview study findings highlight the challenges they face when writing content on Social Networking Sites (SNSs), and their strategies for mitigating these challenges.

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.

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.

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.

Examining the Demand for Spam: Who Clicks?

Conference on Human Factors in Computing Systems (CHI)

Some spam content manages to evade detection and engage users which is why, in this paper, we focus on the demand side of the spam equation examining what drives users to click on spam via a largescale analysis of de-identified, aggregated Facebook log data (n=600,000).
