Audio Description (AD) is a narration designed to enhance accessibility for visually impaired individuals by conveying the key visual elements of a video. Thus, automating AD generation for long-form videos, such as movies and dramas, provides high social value but is a challenging task. First, AD must reflect the narrative context of the entire…

This study aims to design and validate an automatic adaptive caption generation system that addresses the diverse linguistic needs of users who are excluded from conventional video caption services, which typically provide only direct speech-to-text conversion. These users include sign language users with hearing impairments, foreigners learning Korean, and individuals with language development disorders—groups…

Tactile graphics enable visually impaired people to access visual information via touch. Despite extensive guidelines and solutions, effectively representing color, vital for visual communication, remains a key challenge. This research aims to address this gap by developing RainbowTact, inspired by the correlation between visible colors and light wavelengths, to translate colors into intuitive tactile…

This research has analyzed the accessibility of the current metaverse platforms from the perspective of screen reader and switch scanning interface users, using the mixture of quantitative and qualitative assessments. To this end, the two representative metaverse platforms, ZEPETO and Roblox, were targeted. As a result, it was found that the current metaverse platforms…

The purpose of this study is to analyze the accessibility of current metaverse platforms from the perspective of screen reader users, to provide empirical data and the inferences necessary for improved accessibility of the metaverse environment. To this end, the two most representative metaverse platforms, ZEPETO and Roblox, were assessed. As a result of…

Since 2014, the Korean Ministry of Agriculture, Food and Rural Affairs has implemented the Low-Carbon Agricultural Product Certification System to promote voluntary greenhouse gas (GHG) reduction in the agricultural sector. The certification process involves document review, on-site inspection, and post-management, and is intended to be internationally recognized as part of national statistics. However, as…

This study developed an ICT-integrated wearable deep breathing facilitation technology to address key challenges in implementing and managing deep breathing exercises—one of the most widely used cognitive behavioral therapy (CBT) techniques for children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). These challenges include low adherence, difficulty in systematic administration, and lack of objective clinical…

We have developed an assistive technology, called ATCam(Assistive Technology Camera), which is based on deep neural network computer vision technology, to automatically detects and provides context-sensitive appropriate intervention to people with special needs in the context of using a variety of public facilities. The developed ATCam system consists of four inter-related modular components: sensing…

The purpose of this study is to design and validate a new alarm clock method called ‘Social Alarm’. It promotes better wake-up experience, which extends the traditional passive self-struggling wake-up experience into a mutually beneficial activity by sharing an alarm clock with friends who are willing to go together. The effectiveness of this method…

Research Objectives: To develop an AI-empowered technology that automatically evaluates sitting-pivot-transfer performance based on body motion tracking and ambient object recognition with a low-cost time-of-flight sensor.Design: The Cross Industry Standard Process for Data Mining (CRISP-DM) approach with the data collected from multi-site clinical trials was adopted.Setting: The multi-site clinical trials were assessed based on…
