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 […]
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 […]
SoloFinger Robust Microgestures while Grasping Everyday Objects Using microgestures, prior work has successfully enabled gestural interactions while holding objects. Yet, these existing methods are prone to false activations caused by natural finger movements while holding or manipulating the object. We address this issue with SoloFinger, a novel concept that allows design of microgestures that are robust against movements that naturally occur during primary activities. Using […]
Grasping Microgestures Eliciting Single-hand Microgestures for Handheld Objects Our work informs gestural interaction with computer systems while hands are busy holding everyday objects. We present results from the first empirical analysis of over 2,400 microgestures performed by end-users. We call those gestures as Grasping Microgestures. Our key finding is to answer how grasps and object geometries affect the design space of microgestures performed on handheld […]
SmartSleeve Real-time Sensing of Surface and Deformation Gestures on Flexible, Interactive Textiles, using a Hybrid Gesture Detection Pipeline Over the last decades, there have been numerous efforts in wearable computing research to enable interactive textiles. Most work focus, however, on integrating sensors for planar touch gestures, and thus do not fully take advantage of the flexible, deformable and tangible material properties of textile. In this […]
