Human-Robot Interaction: RoSylerNt

Image souce: Capture from video on youtube   The RoSylerNT funded by the Federal Ministry of Education and Research, Germany (BMBF) develops interactive robotic training systems for physical and cognitive stimulation. For this purpose, the learning robot should possess basic skills to perceive posture, movement and human load. This enables the robot to adapt to the person, his or her ability and the respective situation. The attending physician can use the newly gained time more effectively and look after the patients. The newly developed basic skills can also be transferred to domestic or professional scenarios and provide meaningful support for people...

Plan3D: Viewpoint and trajectory optimization for aerial multi-view stereo reconstruction

Plan3D introduces a new method that effciently computes a set of viewpoints and trajectories for high-quality 3D reconstructions in outdoor environments. The goal is to automatically explore an unknown area, and obtain a complete 3D scan of a region of interest (e.g., a large building). Images from a commodity RGB camera, mounted on an autonomously navigated quadcopter, are fed into a multi-view stereo reconstruction pipeline that produces high-quality results but is computationally expensive. In this setting, the scanning result is constrained by the restricted fight time of quadcopters. To this end, Plan3D introduces a novel optimization strategy that respects...

Photoportals: Shared References in Space and Time

Photoportals build on digital photography as a unifying metaphor for reference-based interaction in 3D virtual environments. Virtual photos and videos serve as threedimensional references to objects, places, moments in time and activities of users. Our Photoportals also provide access to intermediate or alternative versions of a scenario and allow the review of recorded task sequences that include life-size representations of the captured users. The research project at the Bauhaus-Universität Weimar (Germany) proposes to exploit such references to structure collaborative activities of collocated and remote users. Photoportals offer additional access points for multiple users and encourage mutual support through the...

HistStadt4D – Urban History in 4 Dimensions

Image source: Julius-Maximilians-Universität Würzburg Dresden scientists are currently working on an App that will make it possible to dive into historic Dresden via the mobile phone.  HistStadt4D is a cooperation project of the Technical University of Dresden and the Julius Maximilian University of Würzburg funded by the Federal Ministry of Education and Research within the framework of the eHumanities Initiative from 01.08.2016 to 31.07.2020. Vision and Objectives The aim is to investigate and develop methods and technologies to transfer extensive repositories of historical media and their contextual information into a three-dimensional spatial model, with an additional temporal component. This...

Indian Women invented Virtual spead breakers

Virtual, a term revisited using the example of an initiative of two women from India According to Oxford dictionary “virtual” in context of computer technology means something that does physically not exist but made by software to appear to do so such as a virtual disc drive or virtual memory. Usually the term virtual is associated or even equated with digital which is because all computer-generated virtual entities are based on digital processes and digital formats. This context is indeed often the case and results in a confusion of meanings, but in fact the meaning of “virtual” is not...
