Shaping Compliance Inducing Haptic Illusion of Compliance in Different Shapes with Electrotactile Grains Abstract Compliance, the degree of displacement under applied force, is pivotal in determining the material perception when touching an object. Vibrotactile actuators can be used for creating grain-based virtual compliance, but they have poor spatial resolution and a limiting rigid form factor. We propose a novel electrotactile compliance illusion that renders grains […]
Flextiles Designing Customisable Shape-Change in Textiles with SMA-Actuated Smocking Patterns Abstract Shape Memory Alloys (SMAs) afford the seamless integration of shape-changing behaviour into textiles, enabling designers to augment apparel with dynamic shaping and styling. However, existing works fall short of providing versatile methods adaptable to varying scales, materials, and applications, curtailing designers’ capacity to prototype customised solutions. To address this, we introduce Flextiles, parameterised SMA […]
WRLKit: Computational Design of Personalized Wearable Robotic Limbs Abstract Wearable robotic limbs (WRLs) augment human capabilities through robotic structures that attach to the user’s body. While WRLs are intensely researched and various device designs have been presented, it remains difficult for non-roboticists to engage with this exciting field. We aim to empower interaction designers and application domain experts to explore novel designs and applications by […]
Double-Sided Tactile Interactions for Grasping in Virtual Reality Abstract For grasping, tactile stimuli to multiple fingertips are crucial for realistic shape rendering and precise manipulation. Pinching is particularly important in virtual reality since it is frequently used to grasp virtual objects. However, the interaction space of tactile feedback around pinching is underexplored due to a lack of means to provide co-located but different stimulation to […]
Biohybrid Devices: Prototyping Interactive Devices with Growable Materials Abstract Living bio-materials are increasingly used in HCI for fabricating objects by growing. However, how to integrate electronics to make these objects interactive still needs to be clarified. This paper presents an exploration of the fabrication design space of Biohybrid Interactive Devices, a class of interactive devices fabricated by merging electronic components and living organisms. From the […]
Design and Fabrication of Body-Based Interfaces (Demo of Saarland HCI Lab) This Interactivity shows live demonstrations of our lab’s most recent work on body-based interfaces. The soft, curved and deformable surface of the human body presents unique opportunities and challenges for interfaces. New form factors, materials and interaction techniques are required that move past the conventional rigid, planar and rectangular devices and the corresponding interaction […]
I Need a Third Arm! Eliciting Body-based Interactions with a Wearable Robotic Arm Abstract Wearable robotic arms (WRA) open up a unique interaction space that closely integrates the user’s body with an embodied robotic collaborator. This space affords diverse interaction styles, including body movement, hand gestures, or gaze. Yet, it is so-far unexplored which commands are desirable from a user perspective. Contributing findings from an […]
Handheld Tools Unleashed A Mixed-Initiative Physical Sketching with a Robotic Printer Abstract Personal fabrication has mostly focused on handheld tools as embodied extensions of the user, and machines like laser cutters and 3D printers automating parts of the process without intervention. Although interactive digital fabrication has been explored as a middle ground, existing systems have a fixed allocation of user intervention vs. machine autonomy, limiting […]
Interactive Bioplastics A DIY approach for composing soft interactive devices from bio-based and bio-degradable materials. Abstract Designers and makers are increasingly interested in leveraging bio-based and bio-degradable “do-it-yourself” (DIY) materials for sustainable prototyping. Their self-produced bioplastics possess compelling properties such as self-adhesion but have so far not been functionalized to create soft interactive devices, due to a lack of DIY techniques for the fabrication of […]
Next Steps in Epidermal Computing Opportunities and Challenges For Soft On-Skin Devices Abstract Skin is a promising interaction medium and has been widely explored for mobile, and expressive interaction. Recent research in HCI has seen the development of Epidermal Computing Devices: ultra-thin and non-invasive devices which reside on the user’s skin, offering intimate integration with the curved surfaces of the body, while having physical and […]
