The technology advancements greatly improved the medical services over time with virtual reality (VR) devices and applications. Currently taking advantage of these recent advancements is the medical rehabilitation field, heavily studied in past few years as a promising VR area. VR-based rehab brings several advantages over the traditional therapy and could deliver personalized in-home treatment without the need of a permanent dedicated supervisor. A device that could make this technology possible is the Microsoft’s new Kinect v2, an improved motion capture sensor available at low prices for personal use. This promising high-tech device can track body movements without the need of additional attached devices that could prove unconformable and expensive. In order to evaluate the medical rehabilitation utility for in-home usage we conducted some research studies and practical experiments focusing on the upper-part of the body in a seated pose in front of a desk. Results indicate that the Kinect sensor can successfully track the body in the proposed scenario and showed great reliability. Occlusion interferences can highly impact the sensor’s overall performance, but in a normal prepared in-home environment the sensor proves to be very efficient.

Natural language interfaces and, in general, Natural Language Processing (NLP) state of the art applications cannot handle satisfactory (if they can at all) conversational implicatures, illocutionary force, stylization, parody, inner disguised polemic, disguised dialogue and other similar phenomena. Considering the ventriloquism perspective in the context of the dialogic-polyphonic theories of Mikhael Bakhtin may provide a basis on trying to cope with such phenomena. The paper introduces some basic ideas of Bakhtin related to ventriloquism in an extended sense, discusses the approaches based on ventriloquism in other domains than NLP, then it analyzes several NLP applications from the perspective of this concept. Several ideas on how the analysis of ventriloquism might be done in NLP are introduced.

This paper aims to showcase a set of features which enables users to develop custom processing models using a specific interface for the workflow. The component presented in this paper, part of the ArcGIS software suite, is called ModelBuilder and allows a visual description of the processing flow, which enable users who do not have extensive programming knowledge to define custom processing models. The tool is also addressed for experienced programmers by having the ability to include scripts within the models and setting them parameters for integration with the workflow. This way, the models can be run either as stand-alone tools, on demand using specific interaction routines - GIS Add-ins, or can be embedded in WebGIS applications by exporting them as geoprocessing services and run through ArcGIS Server or through Cloud services provided by ESRI (the company that develops ArcGIS).
