Update: Our paper “proCover: Sensory Augmentation of Prosthetic Limbs Using Smart Textile Covers” received the Best Paper Award at UIST 2016! Today’s commercially available prosthetic limbs lack tactile sensation and feedback. Recent research in this domain focuses on sensor technologies designed to be directly embedded into future prostheses. We present a novel concept and prototype…
Enhancing Mobile Interaction with a Flexible Sensing and Display Cover FlexCase is a novel flip cover for smartphones, which brings flexible input and output capabilities to existing mobile phones. It combines an e-paper display with a pressure- and bend-sensitive input sensor to augment the capabilities of a phone. Due to the form factor, FlexCase can…
In FlexTiles we demonstrate , a flexible, stretchable pressures sensitive tactile input sensor consisting of three layers of fabric. We show the implementation of FlexTiles for covering large areas, 3D objects, and deformable underlying shapes. In order to measure these large areas with high framerate, we present a measurement implementation and a tiling architecture. To…
A Transparent Self-Sensing Deformable Surface We present FlexSense, a new thin-film, transparent sensing surface based on printed piezoelectric sensors, which can reconstruct complex deformations without the need for any external sensing, such as cameras. FlexSense provides a fully self-contained setup which improves mobility and is not affected from occlusions. Using only a sparse set of…
Idea Archipelago allows users to collect, organize, and share all project related information assets. It can be defined as a project management tool that helps organizing data. The prototype introduces a novel visualization, designed for direct pen-based interaction on digital whiteboards, with the purpose of supporting long-term design projects. Our design has been guided by…
Exploring Pressure-Sensitive Multi-Touch Gestures on Trackpads In this paper, we present Presstures, an extension to current multi-touch operations that enriches common multi-finger gestures with pressure information. By using the initially applied pressure level for implicit mode switching, a gesture can be enhanced with different functionalities to enlarge the interaction space for multi-touch. To evaluate the…
Triggering commands on large interactive surfaces is less efficient than on desktop PCs. It requires either large physical movements to reach an interaction area (e.g., buttons) or additional operations to call context menus (e.g., dwell). There is a lack of efficient ways to trigger shortcuts. We introduce Kolibri – a pen-based gesture system that allows…
Ferroelectric material supports both pyro- and piezoelectric effects that can be used for sensing pressures on large, bended surfaces. We present PyzoFlex, a pressure-sensing input device that is based on a ferroelectric material. It is constructed with a sandwich structure of four layers that can be printed easily on any material. We use this material…
When multiple users are simultaneously sharing a workspace, it is not always clear what should happen when a user invokes an undo action. We explored different user interfaces for undo/redo for co-located collaborative workspaces, such as large interactive whiteboards. A preliminary study revealed that users expect neither a global nor personal undo, but rather a…
In this project we present the NiCE Formula Editor, which recognizes handwritten formulas to provide in situ computation and visualization. Our editor uses a novel hardware setup, suitable for use as a desktop or whiteboard that disambiguates pen and multi-touch input. In our interface, the pen writes and performs gestures, while touch manipulates. Multiple users…
