Style Blink: Exploring Digital Inking of Structured Information via Handcrafted Styling as a First-Class Object

Structured note-taking forms such as sketchnoting, self-tracking journals, and bullet journaling go beyond immediate capture of information scraps. Instead, hand-drawn pride-in-craftmanship increases perceived value for sharing and display. But hand-crafting lists, tables, and calendars is tedious and repetitive. To support these practices digitally, Style Blink ("Style-Blocks+Ink") explores handcrafted styling as a first-class object. Style-blocks encapsulate digital ink, enabling people to craft, modify, and reuse embellishments and decorations for larger structures, and apply custom layouts. For example, we provide interaction instruments that style ink for personal expression, inking palettes that afford creative experimentation, fillable pens that can be "loaded"with commands and actions to replace menu selections, techniques to customize inked structures post-creation by modifying the underlying handcrafted style-blocks and to re-layout the overall structure to match users' preferred template. In effect, any ink stroke, notation, or sketch can be encapsulated as a style-object and re-purposed as a tool. Feedback from 13 users show the potential of style adaptation and re-use in individual sketching practices

Sketchnote Components, Design Space Dimensions, and Strategies for Effective Visual Note Taking

Sketchnoting is a form of visual note taking where people listen to, synthesize, and visualize ideas from a talk or other event using a combination of pictures, diagrams, and text. Little is known about the design space of this kind of visual note taking. With an eye towards informing the implementation of digital equivalents of sketchnoting, inking, and note taking, we introduce a classification of sketchnote styles and techniques, with a qualitative analysis of 103 sketchnotes, and situated in context with six semi-structured follow up interviews. Our findings distill core sketchnote components (content, layout, structuring elements, and visual styling) and dimensions of the sketchnote design space, classifying levels of conciseness, illustration, structure, personification, cohesion, and craftsmanship. We unpack strategies to address particular note taking challenges, for example dealing with constraints of live drawings, and discuss relevance for future digital inking tools, such as recomposition, styling, and design suggestions

Understanding Multi-Device Usage Patterns: Physical Device Configurations and Fragmented Workflows

To better ground technical (systems) investigation and interaction design of cross-device experiences, we contribute an in-depth survey of existing multi-device practices, including fragmented workflows across devices and the way people physically organize and configure their workspaces to support such activity. Further, this survey documents a historically significant moment of transition to a new future of remote work, an existing trend dramatically accelerated by the abrupt switch to work-from-home (and having to contend with the demands of home-at-work) during the COVID-19 pandemic. We surveyed 97 participants, and collected photographs of home setups and open-ended answers to 50 questions categorized in 5 themes. We characterize the wide range of multi-device physical configurations and identify five usage patterns, including: partitioning tasks, integrating multi-device usage, cloning tasks to other devices, expanding tasks and inputs to multiple devices, and migrating between devices. Our analysis also sheds light on the benefits and challenges people face when their workflow is fragmented across multiple devices. These insights have implications for the design of multi-device experiences that support people's fragmented workflows

AirConstellations: In-Air Device Formations for Cross-Device Interaction via Multiple Spatially-Aware Armatures

AirConstellations supports a unique semi-fixed style of cross-device interactions via multiple self-spatially-aware armatures to which users can easily attach (or detach) tablets and other devices. In particular, AirConstellations affords highly flexible and dynamic device formations where the users can bring multiple devices together in-air - with 2-5 armatures poseable in 7DoF within the same workspace - to suit the demands of their current task, social situation, app scenario, or mobility needs. This affords an interaction metaphor where relative orientation, proximity, attaching (or detaching) devices, and continuous movement into and out of ad-hoc ensembles can drive context-sensitive interactions. Yet all devices remain self-stable in useful configurations even when released in mid-air. We explore flexible physical arrangement, feedforward of transition options, and layering of devices in-air across a variety of multi-device app scenarios. These include video conferencing with flexible arrangement of the person-space of multiple remote participants around a shared task-space, layered and tiled device formations with overview+detail and shared-to-personal transitions, and flexible composition of UI panels and tool palettes across devices for productivity applications. A preliminary interview study highlights user reactions to AirConstellations, such as for minimally disruptive device formations, easier physical transitions, and balancing "seeing and being seen"in remote work

Mécanisme de formation de la couche diffuse à l'entrée d'une conduite de section circulaire

Dans cette étude les phénomènes de formation de la couche diffuse sont analysés à partir de la détermination de la charge convectée dans la couche diffuse s'établissant à l'entrée d'un tube. Le profil des vitesses est déterminé théoriquement ainsi que la charge convectée. Les expériences réalisées pour plusieurs longueurs et diamètres de tubes sont ensuite présentées. Enfin, l'étude des résultats expérimentaux obtenus grâce à l'analyse théorique élaborée nous montre que le courant de paroi est très important dans la zone d'entrée du tube

Etude des courants d'écoulement dans un tube rugueux en régime laminaire

Dans ce travail, une première partie est consacrée à l'étude hydrodynamique d'un écoulement laminaire dans un tube muni de rugosités périodiques. Tout d'abord, une analyse théorique permet de déterminer les lignes de courants au voisinage immédiat des aspérités, les dimensions de celles-ci restant toujours très petites devant le diamètre intérieur de la conduite. Ces résultats conduisent dans une deuxième partie, à définir les zones de la couche diffuse qui sont entraînées par l'écoulement puis à calculer la charge convectée et à la comparer aux valeurs obtenues expérimentalement

Mécanisme de formation de la couche diffuse à l'entrée d'une conduite de section circulaire

In this paper we analyse the processus of diffuse layer formation through the phenomenon of charge convection in a diffuse layer appearing at the entrance of a pipe. The velocity profile and the charge convected is computed. Then the experiments obtained for different diameters and lengths of tube are presented. At least, the analyses of the experimental data through the theory elaborated point out the importance of the wall current at the entry of the tube.Dans cette étude les phénomènes de formation de la couche diffuse sont analysés à partir de la détermination de la charge convectée dans la couche diffuse s'établissant à l'entrée d'un tube.
