While directional guidance is essential for spatial navigation, little has been studied about providing nonvisual cues in 3D space individuals who are blind or have limited visual acuity. To understand the effects of different feedback guidance, we conducted a user study with 12 blind-folded participants. They were asked to search virtual target laser pointer as quickly possible under 6 designs varying mode (beeping vs. haptic beeping+haptic) and presence stereo sound. Our findings show that...
Providing directional guidance is important especially for exploring unfamiliar environments. However, most studies are limited to two-dimensional when many interactions happen in 3D spaces. Moreover, visual feedback that often used communicate the position of a particular object may not be available situations target occluded by other objects or located outside one's field view, due overload light conditions. Inspired prior finding showed users' tendency scanning space one direction at...
A number of studies have been conducted to understand the accessibility issues that people with visual impairments experience. However, most these are limited navigation and object recognition tasks. In this study, we focused on providing mealtime assistance. We first a preliminary online survey 91 participants an in-depth interview study eight two social workers. Based findings, identified various difficulties face during mealtimes, types dish-related information they wish get before meals....
It is difficult for people with visual impairments to have balanced nutrition, and one of the reasons because it challenging them shop grocery items. In this study, we focused on designing descriptions items help making purchase decisions independently. To identify types information be provided, first conducted an online survey 73 participants impairments. Then in-depth phone interview eight understand how better design different Based findings, provide implications a camera-based wearable...
This paper describes a community effort to improve earlier versions of the full-text corpus Genomics & Informatics by semi-automatically detecting and correcting PDF-to-text conversion errors optical character recognition during first hackathon Annotation Hackathon (GIAH) event. Extracting text from multi-column biomedical documents such as is known be notoriously difficult. The was piloted part coding competition ELTEC College Engineering at Ewha Womans University in order enable...
It is difficult for non-experts to build machine learning (ML) models at the level that satisfies their needs. Deep are even more challenging because it unclear how improve model, and a trial-and-error approach not feasible since training these time-consuming. To assist novice users, we examined interactive explainable feedback while deep network can contribute model performance users’ satisfaction, focusing on data preparation process. We conducted user study with 31 participants without...
Conveying directional feedback is important for individuals who are blind or have limited visual acuity. However, most studies focused on supporting two-dimensional guidance. In this work, we investigated the effects of different nonvisual conditions providing guidance in a three-dimensional space. We conducted user study with six people low vision to investigate stereo sound (on vs. off) and modalities (beeping vibration beeping+vibration). Participants were asked point series virtual...
