Designing Safe Spaces for Virtual Reality
Ethics in Design and Communication
Virtual Reality (VR) designers accept the ethical responsibilities of removing a user’s entire world and superseding it with a fabricated reality. These unique immersive design challenges are intensified when virtual experiences become public and socially-driven. As female VR designers in 2018, we see an opportunity to fold the language of consent into the design practice of virtual reality—as a means to design safe, accessible, virtual spaces.
Publication will be made available in 2020.

“I just want to feel safe”: A Diary Study of Safety Perceptions on Social Media
International AAAI Conference on Web and Social Media (ICWSM)
While prior work has individually explored specific threats to safety—privacy, security, harassment—in this work we more broadly capture and characterize the full breadth of day-to-day experiences that influence users’ overall perceptions of safety on social media.

Psychophysical Evaluation of Persistence- and Frequency-Limited Displays for Virtual and Augmented Reality
SID Display Week
Little is known about user sensitivity to flicker and eye movement-induced ghosting at refresh rates and persistence levels relevant for head-mounted displays (HMDs). In this report, we describe a pair of psychophysical experiments that we performed to comprehensively quantify these artifacts and make general recommendations for HMD design.

Pseudo-Haptic Weight: Changing the Perceived Weight of Virtual Objects By Manipulating Control-Display Ratio
ACM CHI Conference on Human Factors in Computing Systems
In virtual reality, the lack of kinesthetic feedback often prevents users from experiencing the weight of virtual objects. Control-to-display (C/D) ratio manipulation has been proposed as a method to induce weight perception without kinesthetic feedback. Based on the fact that lighter (heavier) objects are easier (harder) to move, this method induces an illusory perception of weight by manipulating the rendered position of users’ hands—increasing or decreasing their displayed movements.

Understanding Perceptions of Problematic Facebook Use
ACM Conference on Human Factors in Computing Systems (CHI)
While many people use social network sites to connect with friends and family, some feel that their use is problematic, seriously affecting their sleep, work, or life. Pairing a survey of 20,000 Facebook users measuring perceptions of problematic use with behavioral and demographic data, we examined Facebook activities associated with problematic use as well as the kinds of people most likely to experience it.

Design and Evaluation of a Social Media Writing Support Tool for People with Dyslexia
ACM CHI Conference on Human Factors in Computing Systems
We evaluated the performance and the design of AWH through a week-long field study with 19 people with dyslexia and received highly positive feedback. Our field study demonstrated the value of providing better and more extensive writing support on SNSs, and the potential of AI for building a more inclusive Internet.

Lost in Style: Gaze-driven Adaptive Aid for VR Navigation
ACM CHI Conference on Human Factors in Computing Systems
We introduce a novel adaptive aid that maintains the effectiveness of traditional aids, while equipping designers and users with the controls of how often help is displayed.

An Explanation of Fitts’ Law-like Performance in Gaze-Based Selection Tasks Using a Psychophysics Approach
ACM CHI Conference on Human Factors in Computing Systems
Using a vision science-inspired model, we here show that a Fitts’-like distribution of movement times can arise due to the execution of secondary saccades, especially when targets are small.

The Impact of Avatar Tracking Errors on User Experience in VR
IEEE Conference on Virtual Reality
This paper presents a series of experiments employing a sizable subject pool (n=96) that study the impact of motion tracking errors on user experience for activities including social interaction and virtual object manipulation.

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.
