We present an augmented virtuality system using low-cost or outdated devices as sensors, attached to tangible objects. Five interactions were implemented, featuring rotation, pressing, pulling, pushing and insertion movements, including passive mechanical resistance. Interactions were tied together by a puzzling narrative. Concerning storytelling, in contrast to AR, pure virtual reality offers unlimited visual possibilities and higher flexibility. Augmenting VR with physical objects allows ignoring most details of the physical environment and exploring ‘magical’ interactions. Precise registration was accomplished using wireless tracking system. The main challenge was the absent physical counterparts of the scenario, which was tackled by limiting user's reach to available interactions. Despite Leap Motion's erratic hand tracking, mouse and tablet sensors were precise enough and the augmented environment allowed a high sense of presence.

In this work, we present a hand-based natural interaction that allows performing fundamental actions such as moving or controlling objects and climbing ladders. The setup was restricted to available consumer VR technology, aiming to advance towards a practical unified framework for 3D interaction. The strategy was syncing the closest natural movement allowed by the device with primary task actions, either directly or indirectly, creating hypernatural UIs. The prototype allowed successful completion of the three challenges proposed by the 2018 3DUI Contest, as validated by a preliminary user study with participants from the target audience and also from the general public.

This demo presents a fully immersive and interactive virtual environment (VE) - the ArcheoVR, which represents Itapeva Rocky Shelter, a prehistoric archeological site in Brazil. W workflow started with a real world data capture - laser scanners, drones and photogrammetry. Captured information was transformed into a carefully designed realistic 3D scene and interactive features that allows users to experience the virtual archeological site in real-time. The main objective of this VR model is to allow the general public to feel and explore an otherwise restricted and ephemeral site and to assess prototype tools intended for future digital archaeological exploration.

In this work we present an interactive and collaborative 3D object manipulation system using the shelf mobile devices coupled with Augmented Reality (AR) technology that allows multiple users to collaborate concurrently on a scene. Each user interested in participating in this collaboration uses both a mobile device running android and a desktop (or laptop) working in tandem. The 3D scene was visualized by the user in the desktop system. The changes in the scene viewpoint changes and the object manipulations were performed using a mobile device through the AR. The system leverages user's knowledge of common tasks performed on current mobile devices such as pinching for zooming in and out; swiping with one or two fingers for object rotation and press-and-hold for 2 seconds for object translation. As you will see in this video, we built a prototype system (in a maze style) and applied an informal user study with three experienced VR researchers. Users had to carry a 3D cube through three square rings along the maze. In resume, we diagnosed that working in a collaborative way (users A and B) was better and easier than individual one (user C). We registered more than 2 minutes late for the individual experience comparing to the teamwork. It may happen because the two player team shared information, functions and had a multi-perspective view during the task.
