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 […]
SparseIMU: Computational Design of Sparse IMU Layouts for Sensing Fine-Grained Finger Microgestures Abstract Gestural interaction with freehands and while grasping an everyday object enables always-available input. To sense such gestures, minimal instrumentation of the user’s hand is desirable. However, the choice of an effective but minimal IMU layout remains challenging, due to the complexity of the multi-factorial space that comprises diverse finger gestures, objects and […]
Computational Design and Optimization of Electro-Physiological Sensors Abstract Electro-physiological sensing devices are becoming increasingly common in diverse applications. However, designing such sensors in compact form factors and for high-quality signal acquisition is a challenging task even for experts, is typically done using heuristics, and requires extensive training. Our work proposes a computational approach for designing multi-modal electro-physiological sensors. By employing an optimization-based approach alongside an […]
Weirding Haptics In-Situ Prototyping of Vibrotactile Feedback in Virtual Reality through Vocalization Effective haptic feedback in virtual reality (VR) is an essential element for creating convincing immersive experiences. To design such feedback, state-of-the-art VR setups provide APIs for programmatically generating controller vibration patterns. While tools for designing vibrotactile feedback keep evolving, they often require expert knowledge and rarely support direct manipulation methods for mapping feedback […]
BodyStylus Freehand On-Body Design and Fabrication of Epidermal Interfaces In traditional body-art, designs are adjusted to the body as they are applied, enabling creative improvisation and exploration. Conventional design and fabrication methods of epidermal interfaces, however, separate these steps. With BodyStylus we present the first computer-assisted approach for on-body design and fabrication of epidermal interfaces. Inspired by traditional techniques, we propose a hand-held tool that […]
bARefoot Generating Virtual Materials using Motion Coupled Vibration in Shoes Many features of materials can be experienced through tactile cues, even using one’s feet. For example, one can easily distinguish between moss and stone without looking at the ground. However, this type of material experience is largely not supported in AR and VR applications. We present bARefoot, a prototype shoe providing tactile impulses tightly coupled […]
PhysioSkin Rapid Fabrication of Skin-Conformal Physiological Interfaces Advances in rapid prototyping platforms have made physiological sensing accessible to a wide audience. However, off-the-shelf electrodes commonly used for capturing biosignals are typically thick, non-conformal and do not support customization. We present PhysioSkin, a rapid, do-it-yourself prototyping method for fabricating custom multi-modal physiological sensors, using commercial materials and a commodity desktop inkjet printer. It realizes ultrathin skin-conformal […]
Soft Inkjet Circuits Rapid Multi-Material Fabrication of Soft Circuits Using a Commodity Inkjet Printer Despite the increasing popularity of soft interactive devices, their fabrication remains complex and time consuming.

Tactlets Adding Tactile Feedback to 3D Objects Using Custom Printed Controls Rapid prototyping of haptic output on 3D objects promises to enable a more widespread use of the tactile channel for ubiquitous, tangible, and wearable computing. Existing prototyping approaches, however, have limited tactile output capabilities, require advanced skills for design and fabrication, or are incompatible with curved object geometries. In this paper, we present a […]
Multi-Touch Kit A Do-It-Yourself Technique for Capacitive Multi-Touch Sensing Using a Commodity Microcontroller Mutual capacitance-based multi-touch sensing is now a ubiquitous and high-fidelity input technology. However, due to the complexity of electrical and signal processing requirements, it remains very challenging to create interface prototypes with custom-designed multi-touch input surfaces. In this paper, we introduce the Multi-Touch Kit, a technique enabling electronics novices to rapidly prototype […]
