User-generated videos are an increasingly important source of information online, yet most online inaccessible to blind and visually impaired (BVI) people. To find that accessible, or understandable without additional description the visual content, BVI people in our formative studies reported they used a time-consuming trial-and-error approach: clicking on video, watching portion, leaving repeating process. also video accessibility heuristics characterize accessible videos. We instantiate 7...

Olfactory dysfunction is an early pre-motor symptom of Parkinson's disease (PD) but the neural mechanisms underlying this remain largely unknown. Aggregation α-synuclein observed in olfactory bulb (OB) during stages PD, indicating a relationship between pathology and hyposmia. Here we investigate whether how aggregates modulate activity OB at single-cell synaptic levels. We induced aggregation specifically via overexpression double-mutant human by adeno-associated viral (AAV) vector. found...

In recent years, there has been a proliferation of multimedia applications that leverage machine learning (ML) for interactive experiences. Prototyping ML-based is, however, still challenging, given complex workflows are not ideal design and experimentation. To better understand these challenges, we conducted formative study with seven ML practitioners to gather insights about common evaluation workflows.

Video conferencing solutions like Zoom, Google Meet, and Microsoft Teams are becoming increasingly popular for facilitating conversations, recent advancements such as live captioning help people better understand each other. We believe that the addition of visuals based on context conversations could further improve comprehension complex or unfamiliar concepts. To explore potential capabilities, we conducted a formative study through remote interviews (N=10) crowdsourced dataset over 1500...

Images on social media platforms are inaccessible to people with vision impairments due a lack of descriptions that can be read by screen readers. Providing accurate alternative text for all visual content is not yet feasible, but certain subsets images, such as internet memes, offer affordances automatic or semi-automatic generation text. We present two methods making memes accessible semi-automatically through (1) the rich and (2) creation audio macro memes. Meme authors create templates...

The fusiform face area (FFA) is a widely studied region causally involved in perception. Even though cognitive neuroscientists have been studying the FFA for over two decades, answers to foundational questions regarding function, architecture, and connectivity of from large (N>1000) group participants are still lacking. To fill this gap knowledge, we quantified these multimodal features face-selective regions 1053 Human Connectome Project. After manually defining 4,000 regions, report five...

Authors make their videos visually accessible by adding audio descriptions (AD), and auditorily closed captions (CC). However, creating AD CC is challenging tedious, especially for non-professional describers captioners, due to the difficulty of identifying accessibility problems in videos. A video author will have watch through manually check inaccessible information frame-by-frame, both visual auditory modalities. In this paper, we present CrossA11y, a system that helps authors efficiently...

Situationally Induced Impairments and Disabilities (SIIDs) can significantly hinder user experience in contexts such as poor lighting, noise, multi-tasking. While prior research has introduced algorithms systems to address these impairments, they predominantly cater specific tasks or environments fail accommodate the diverse dynamic nature of SIIDs. We introduce Human I/O, a unified approach detecting wide range SIIDs by gauging availability human input/output channels. Leveraging egocentric...

In recent years, live captions have gained significant popularity through its availability in remote video conferences, mobile applications, and the web. Unlike preprocessed subtitles, require real-time responsiveness by showing interim speech-to-text results. As prediction confidence changes, may update, leading to visual instability that interferes with user's viewing experience. this paper, we characterize stability of proposing a vision-based flickering metric using luminance contrast...
