Hello! I'm Alexa, a PhD Student at Stanford University.
My research interests are primarily in the fields of Human-Computer Interaction and Accessibility. I am interested in the design of physical interfaces that leverage multimodal perception to make spatial information more accessible for people who are blind. Application areas of interest include supporting design, collaboration, and information visualization.
Currently, I am part of the shape lab and the Stanford HCI Group, advised by Prof. Sean Follmer. Previously, I completed my M.S. in Mechanical Engineering also at Stanford and my B.S. in Biomedical Engineering at Georgia Tech with a minor in Computer Science.
Haptic PIVOT: On-Demand Handhelds in VR
PIVOT is a wrist-worn haptic device that renders virtual objects into the user’s hand on demand. Its simple design comprises a single actuated joint that pivots a haptic handle into and out of the user’s hand, rendering the haptic sensations of grasping, catching, or throwing an object – anywhere in space .
Virtual Reality Without Vision: A Haptic and Auditory White Cane to Navigate Complex Virtual Worlds
How might virtual reality (VR) aid a blind person in familiarization with an unexplored space? Exploring the design of immersive VR experiences accessible to blind people with the goal of facilitating orientation and mobility training.
shapeCAD: An Accessible 3D Modelling Workflow for the Blind and Visually-Impaired Via 2.5D Shape Displays
We describe our participatory design process towards designing an accessible 3D modelling workflow for the blind and visually-impaired. We discuss interactions that enable blind users to design, program, and create using a 2.5D interactive shape display.
shapeShift: A Mobile Tabletop Shape Display for Tangible and Haptic Interaction
We explore interactions enabled by 2D spatial manipulation and self-actuation of a mobile tabletop shape display (e.g. manipulating spatial-aware content, an encountered-type haptic device, etc). We present the design of a novel open-source shape display platoform called shapeShift.
