International audienceWe present SLAPbook, an application using SLAP, translucent and tangible widgets for use on vision-based multi-touch tabletops in Single Display Groupware (SDG) environments. SLAP stands for Silicone ILluminated Active Peripherals and includes widgets such as sliders, knobs, keyboards, and buttons. The widgets add tactile feedback to multi-touch tables while simultaneously providing dynamic relabeling to tangible objects using the table's rear projection. SLAPbook provides multiple users the ability to add and edit content to a guestbook, browse other peoples' entries, and access personal data using a token-based personalization system. Interaction with the table takes place in the personal and public space so that users can make use of personal and shared controls to perform separate and coordinative actions

Rozhovor Britských listů 404. Můžeme po tornádu ignorovat klimatickou katastrofu? [Britské listy Interview 404. Can we afford to ignore the climate catastrophe, after a tornado has devastated villages in the Czech Republic?]

On 24th June from about 7.20 pm, unusually, a tornado devastated a number of villages in Southern Moravia, Czech Republic. Central Europe has recently experienced a number of instances of extreme weather. Can this impact of global warming be ignored or what action should be taken? Jan Čulík talks about this to the Czech environmentalist Jan Hollan from Czech Globe, the Institute for the Study of Global Change at Masaryk University, Brno. The interview was broadcast on the Czech cable TV station from 2nd july, 2021

ObjecTop: Occlusion Awareness of Physical Objects on Interactive Tabletops

In this paper, we address the challenges of occlusion created by physical objects on interactive tabletops. We contribute an integrated set of interaction techniques designed to cope with the physical occlusion problem as well as facilitate organizing objects in hybrid settings. These techniques are implemented in ObjecTop, a system to support tabletop display applications involving both physical and virtual objects. We compile design requirements for occlusion-aware tabletop systems and conduct the first in-depth user study comparing ObjecTop with conventional tabletop interfaces in search and layout tasks. The empirical results show that occlusion-aware techniques outperform the conventional tabletop interface. Furthermore, our findings indicate that physical properties of occluders dramatically influence which strategy users employ to cope with occlusion. We conclude with a set of design implications derived from the study

Mapování světelného znečištění a negativní vlivy osvětlování umělým světlem na živou přírodu na území České republiky

Cílem úkolu je zmapování zdrojů umělého osvětlení na území České republiky, zjištění vlivu jednotlivých typů zdrojů na životní prostředí, ocenění negativních vlivů na složky živé přírody a procesy v přírodě probíhající. Podařilo se shromáždit přehledy problematiky z několika oborů a provést některé výzkumy poprvé ve světovém měřítku. Hlavní závěry: noční prostředí je již velmi narušené, populace hmyzu jsou ztenčené vinou venkovního svícení na zlomky původních, alespoň milionu obyvatel denně vadí nemístné světlo v noci, obloha se za uplynulé půlstoletí stala světlejší jednoznačně vinou rostoucích emisí, škodlivé emise lze bez újmy na funkčnosti venkovního osvětlení velmi snížit technickými opatřeními

Slap widgets: bridging the gap between virtual and physical controls on tabletops

We present Silicone iLluminated Active Peripherals (SLAP), a system of tangible, translucent widgets for use on multitouch tabletops. SLAP Widgets are cast from silicone or made of acrylic, and include sliders, knobs, keyboards, and buttons. They add tactile feedback to multi-touch tables, improving input accuracy. Using rear projection, SLAP Widgets can be relabeled dynamically, providing inexpensive, battery-free, and untethered augmentations. Furthermore, SLAP combines the flexibility of virtual objects with physical affordances. We evaluate how SLAP Widgets influence the user experience on tabletops compared to virtual controls. Empirical studies show that SLAP Widgets are easy to use and outperform virtual controls significantly in terms of accuracy and overall interaction time.
