SkillComposer: Learning Reusable Skills for Natural-Language Robot Programming
John Woods, Hasti Seifi
Natural-language interfaces can lower the barrier to programming robots, but existing systems struggle when users request complex tasks. While large language models (LLMs) perform…
VisionPulse: A Virtual Reality System Enabling Accessible Discovery and Navigation for Blind and Low Vision Users
Samuel Martin, Pooyan Fazli, Hasti Seifi
Free exploration is an important aspect of many engaging virtual reality (VR) experiences, yet remains largely inaccessible to blind and low vision (BLV) users due to its reliance…
Adaptive Geodesic Conformal Prediction for Egocentric Camera Pose Estimation
Aishani Pathak, Hasti Seifi
Egocentric pose estimation for Augmented Reality (AR) and assistive devices requires not just accurate predictions but guaranteed uncertainty regions. Conformal prediction (CP) pro…
Sound2Hap: Learning Audio-to-Vibrotactile Haptic Generation from Human Ratings
Yinan Li, Hasti Seifi
Environmental sounds like footsteps, keyboard typing, or dog barking carry rich information and emotional context, making them valuable for designing haptics in user applications.…
DescribePro: Collaborative Audio Description with Human-AI Interaction
Maryam Cheema, Sina Elahimanesh, Samuel Martin +2
Audio description (AD) makes video content accessible to millions of blind and low vision (BLV) users. However, creating high-quality AD involves a trade-off between the precision…
ChartQA-X: Generating Explanations for Visual Chart Reasoning
Shamanthak Hegde, Pooyan Fazli, Hasti Seifi
The ability to explain complex information from chart images is vital for effective data-driven decision-making. In this work, we address the challenge of generating detailed expla…
Text Entry for XR Trove (TEXT): Collecting and Analyzing Techniques for Text Input in XR
Arpit Bhatia, Moaaz Hudhud Mughrabi, Diar Abdlkarim +4
Text entry for extended reality (XR) is far from perfect, and a variety of text entry techniques (TETs) have been proposed to fit various contexts of use. However, comparing betwee…
VideoA11y: Method and Dataset for Accessible Video Description
Chaoyu Li, Sid Padmanabhuni, Maryam Cheema +2
Video descriptions are crucial for blind and low vision (BLV) users to access visual content. However, current artificial intelligence models for generating descriptions often fall…
Can a Machine Feel Vibrations?: A Framework for Vibrotactile Sensation and Emotion Prediction via a Neural Network
Chungman Lim, Gyeongdeok Kim, Su-Yeon Kang +2
Vibrotactile signals offer new possibilities for conveying sensations and emotions in various applications. Yet, designing vibrotactile tactile icons (i.e., Tactons) to evoke speci…
Describe Now: User-Driven Audio Description for Blind and Low Vision Individuals
Maryam Cheema, Hasti Seifi, Pooyan Fazli
Audio descriptions (AD) make videos accessible for blind and low vision (BLV) users by describing visual elements that cannot be understood from the main audio track. AD created by…
Hovering Over the Key to Text Input in XR
Mar Gonzalez-Franco, Diar Abdlkarim, Arpit Bhatia +6
Virtual, Mixed, and Augmented Reality (XR) technologies hold immense potential for transforming productivity beyond PC. Therefore there is a critical need for improved text input s…
An Interactive Tool for Simulating Mid-Air Ultrasound Tactons on the Skin
Chungman Lim, Hasti Seifi, Gunhyuk Park
Mid-air ultrasound haptic technology offers a myriad of temporal and spatial parameters for contactless haptic design. Yet, predicting how these parameters interact to render an ul…
Designing Distinguishable Mid-Air Ultrasound Tactons with Temporal Parameters
Chungman Lim, Gunhyuk Park, Hasti Seifi
Mid-air ultrasound technology offers new design opportunities for contactless tactile patterns (i.e., Tactons) in user applications. Yet, few guidelines exist for making ultrasound…
AdapTics: A Toolkit for Creative Design and Integration of Real-Time Adaptive Mid-Air Ultrasound Tactons
Kevin John, Yinan Li, Hasti Seifi
Mid-air ultrasound haptic technology can enhance user interaction and immersion in extended reality (XR) applications through contactless touch feedback. Yet, existing design tools…
Clustering Social Touch Gestures for Human-Robot Interaction
