ExTouch: Spatially-aware embodied manipulation of actuated objects mediated by augmented reality

As domestic robots and smart appliances become increasingly common, they require a simple, universal interface to control their motion. Such an interface must support a simple selection of a connected device, highlight its capabilities and allow for an intuitive manipulation. We propose "exTouch", an embodied spatially-aware approach to touch and control devices through an augmented reality mediated mobile interface. The "exTouch" system extends the users touchscreen interactions into the real world by enabling spatial control over the actuated object. When users touch a device shown in live video on the screen, they can change its position and orientation through multi-touch gestures or by physically moving the screen in relation to the controlled object. We demonstrate that the system can be used for applications such as an omnidirectional vehicle, a drone, and moving furniture for reconfigurable room

Second surface: multi-user spatial collaboration system based on augmented reality

An environment for creative collaboration is significant for enhancing human communication and expressive activities, and many researchers have explored different collaborative spatial interaction technologies. However, most of these systems require special equipment and cannot adapt to everyday environment. We introduce Second Surface, a novel multi-user Augmented reality system that fosters a real-time interaction for user-generated contents on top of the physical environment. This interaction takes place in the physical surroundings of everyday objects such as trees or houses. Our system allows users to place three dimensional drawings, texts, and photos relative to such objects and share this expression with any other person who uses the same software at the same spot. Second Surface explores a vision that integrates collaborative virtual spaces into the physical space. Our system can provide an alternate reality that generates a playful and natural interaction in an everyday setup

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

We-Coupling!

Positive social and collaborative effects are hailed as a major advantage of embodied and tangible approaches to interaction. This studio offers a hands-on exploration of potentially extreme versions of such benefits Systems and techniques that somehow share or transfer embodiment between two or more people. Through participatory demos, studio attendees will explore and compare a variety of approaches to experiencing the perspectives of another body, and controlling bodies other than their own. These comparisons will be a launch pad for collaboratively combining existing "body sharing" systems and mocking up new design concepts. By bringing together ideas and approaches in an actionable manner, this studio will share and develop imagination, theory, and skills relevant to the design and study of interactive systems in which the body plays a central role
