Design Considerations for Human Oversight of AI: Insights from Co-Design Workshops and Work Design Theory

As AI systems become increasingly capable and autonomous, domain experts’ roles are shifting from performing tasks themselves to overseeing AI-generated outputs. Such oversight is critical, as undetected errors can have serious consequences or undermine the benefits of AI. Effective oversight, however, depends not onl…

How are Vibrotactile Experiences Visually Represented? A Taxonomy of Illustration Characteristics

Vibrotactile experiences (VTX) consist of a multitude of design parameters and experiential dimensions that can be challenging to communicate visually. To understand how this is commonly done in scientific communication, we systematically reviewed VTX illustrations in academic publications. Using inductive and deducti…

Beyond Descriptions: A Generative Scene2Audio Framework for Blind and Low-Vision Users to Experience Vista Landscapes

Current scene perception tools for Blind and Low Vision (BLV) individuals rely on spoken descriptions but lack engaging representations of visually pleasing distant environmental landscapes (Vista spaces). Our proposed Scene2Audio framework generates comprehensible and enjoyable nonverbal audio using generative models…

HaptEx: Investigating Haptic Notification Channels for Exoskeletons Across Different Levels of Actuation

Exoskeletons are increasingly deployed in real-world contexts, where communicating critical system states or unexpected events is important for effective interaction. Haptic feedback offers a direct communication channel, integrating naturally with the actuated body region. Yet, it remains unclear how well haptic feed…

Forefeel the Move: Investigating Proprioceptive Feedback for Communicating Imminent Motions of Body-actuating Systems

Systems actuating the body can proactively assist users in diverse tasks. However, unexpected body actuation may pose safety risks. We propose proprioceptive feedback to inform users about an imminent actuation before the system takes control. In a user study, we compare different proprioceptive cues that either inter…

EmbroForm: Digital Fabrication of Soft Freeform Objects with Machine Embroidered Pull-up Strings

Pull-up objects form 3D shapes by pulling a string routed through a 2D material, offering low-cost 2D fabrication and reversible transformation. However, existing approaches rely on origamic folding, which creates faceted, oftentimes rigid surfaces and requires manual pull-up string routing. We introduce EmbroForm, a…

Emotion Through Motion: How Shape-Changing Jewelry Conveys Emotions

Shape-changing wearables are known to convey emotions to wearers and observers, and jewelry is commonly worn for self-expression and to be seen by others. But how do individual shape change parameters impact the emotions communicated? In a first study, participants observed a shape-changing necklace; the second incl…

Privacy & Safety Challenges of On-Body Interaction Techniques

On-body computing systems offer new forms of interaction, but while they are increasingly integrated into everyday contexts, their unique privacy and safety challenges remain understudied. This paper examines these challenges through a two-round interview study with $N = 15$ experts in human-computer interaction, an…

Efficient Human-in-the-Loop Optimization via Priors Learned from User Models

Human-in-the-loop optimization identifies optimal interface designs by iteratively observing user performance. However, it often requires numerous iterations due to the lack of prior information. While recent approaches have accelerated this process by leveraging previous optimization data, collecting user data remain…

User-reconfigured Haptics: Combining User-Reconfiguration and Visual Manipulations to Enhance Dynamic Passive Haptic Experiences for VR

Virtual Reality (VR) depends on haptic feedback to create immersive experiences. Traditional passive proxies align physical props with their virtual counterparts but remain limited in scalability and expressiveness, or require bulky actuators to support reconfiguration. We introduce User-reconfigured Haptics, an appro…
