HapticLens: Interactive Vibrotactile Haptic Generation from Spatially Localized Video Motion

Unlike visual and auditory media, physical sensations are difficult to create and capture, limiting the availability of diverse haptic content. Converting common media formats like video into haptics offers a promising solution, but existing video-to-haptics methods depend on specific characteristics, such as camera…

Sound2Hap: Learning Audio-to-Vibrotactile Haptic Generation from Human Ratings

Environmental sounds like footsteps, keyboard typing, or dog barking carry rich information and emotional context, making them valuable for designing haptics in user applications. Existing audio-to-vibration methods, however, rely on signal-processing rules tuned for music or games and often fail to generalize across…

Describe Now: User-Driven Audio Description for Blind and Low Vision Individuals

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 professionals or novice describers is time-consuming and offers little customization or control to BLV viewers on description length and c…

Text Entry for XR Trove (TEXT): Collecting and Analyzing Techniques for Text Input in XR

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 between TETs remains challenging due to the lack of a consolidated collection of techniques, and limited understanding of how interaction attribu…

HapticGen: Generative Text-to-Vibration Model for Streamlining Haptic Design

Designing haptic effects is a complex, time-consuming process requiring specialized skills and tools. To support haptic design, we introduce HapticGen, a generative model designed to create vibrotactile signals from text inputs. We conducted a formative workshop to identify requirements for an AI-driven haptic model.…

ChatHAP: A Chat-Based Haptic System for Designing Vibrations through Conversation

In contrast to design tools for graphics and audio generation from text prompts, haptic design tools lag behind due to challenges in constructing large-scale, high-quality datasets including vibrations and text descriptions. To address this gap, we propose ChatHAP, a conversational haptic system for designing vibratio…

VideoA11y: Method and Dataset for Accessible Video Description

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 short due to limitations in the quality of human annotations within training datasets, resulting in descriptions that do not fully meet BL…

AdapTics: A Toolkit for Creative Design and Integration of Real-Time Adaptive Mid-Air Ultrasound Tactons

Mid-air ultrasound haptic technology can enhance user interaction and immersion in extended reality (XR) applications through contactless touch feedback. Yet, existing design tools for mid-air haptics primarily support creating tactile sensations (i.e., tactons) which cannot change at runtime. These tactons lack expre…

Designing Distinguishable Mid-Air Ultrasound Tactons with Temporal Parameters

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 Tactons easy to distinguish for users. In this paper, we investigated the distinguishability of temporal parameters of ultrasound Tactons…

CHI '244th AuthorAR Navigation & Context Awareness +1

Using the Visual Language of Comics to Alter Sensations in Augmented Reality

Augmented Reality (AR) excels at altering what we see but non-visual sensations are difficult to augment. To augment non-visual sensations in AR, we draw on the visual language of comic books. Synthesizing comic studies, we create a design space describing how to use comic elements (e.g., onomatopoeia) to depict non-v…
