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.

Bellowband: A Pneumatic Wristband for Delivering Local Pressure and Vibration

IEEE World Haptics Conference

In this paper we present the design and control of Bellowband, a pneumatic wristband for localized pressure and vibration haptic feedback. The wristband has eight equally spaced pneumatic bellows that extend into the wrist, constructed from layers of polyester thermoplastic polyurethane (TPU), resulting in a flexible, lightweight (11 g) band capable of rendering complex pressure and vibration cues to the user.

Z-Qualities and Renderable Mass-Damping-Stiffness Spaces: Describing the Set of Renderable Dynamics of Kinesthetic Haptic Displays

IEEE World Haptics Conference

In this paper we define language and definitions to define the renderable set of dynamics that a general kinesthetic haptic display can render to a human operator.

A Balanced Hybrid Active-Passive Actuation Approach for HighPerformance Haptics

IEEE World Haptics Conference

Hybrid actuation approaches for haptic interfaces generally suffer from asymmetry in active and passive torque capabilities. This paper describes the design of a high-performance balanced hybrid haptic device, which addresses the asymmetry by combining a high-power, low-impedance active compliant actuation (series-elastic actuator) with energy absorbing high-force passive actuation in parallel with a fast, low-power secondary active actuation.

Perceptual Limits of Visual-Haptic Simultaneity in Virtual Reality Interactions

IEEE World Haptics Conference

The goal of this work is to establish the range of visual-haptic asynchronies that go unnoticed when touching an object. To perform a psychophysical study, however, we would need asynchronous visual-haptic stimuli, but because the contact of the finger with a real object inevitably creates synchronized haptic feedback, here we employ instead a virtual reproduction of the interaction.

Tactile Echoes: A Wearable System for Tactile Augmentation of Objects

IEEE World Haptics Conference

We present Tactile Echoes, a wearable system for augmenting tactile interactions with any object. This system senses vibrations in the fingertip that are produced by interactions of the finger with a touched object. It processes the vibration signals in real-time via a parametric signal network and returns them to the finger as “Tactile Echoes” of the touch interaction.

“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.
