Kinect 1.7 SDK Released

Posted by PL   |   Filed under: UX

The new Kinect SDK will be release on 18th March. This release should include a new and improved Human Interface Guidelines (HIG) and a new Interaction flow management, that should allow the recognition of new gesture at library level, such as push, grip and support for smart ways to accommodate multiple users and two-person interactions.

Accelerating Shadow Rays Using Volumetric Occluders

Posted by PL   |   Filed under: 3D

A paper focused on the use of volumetric occluders stored within a kd-tree in order to accelerate shadow rays cast on a closed, watertight mesh. Intersection with a volumetric occluder is much cheaper than intersection with mesh geometry, although performing these intersections requires modification to the traversal order through the kd-tree.
Authors' approach provides a performance improvement of up to 2.0x for their test scenes while producing images identical to those produced by the unaccelerated baseline.
Authors: Peter Djeu and Sean Keely, University of Texas at Austin; Warren Hunt, Intel Labs.

Using the Doppler Effect to sense gestures

Posted by PL   |   Filed under: UX

Microsoft Research has presented a new technology (called Soundwave) that allows users to control the software on their computers with the movement of their hands.
The goal is reached without using camera (like Kinect): Soundwave relies only on speaker and microfone, and uses the Doppler Effect (at human-inaudible frequency tone) to recognize various gestures, when the user moves hands in front of the screen interrupting the tone.
It's an interesting technology because of does not need any hardware sensor other then microphone and speakers that are already present on common device (pc and mobile).

WWW2012 - Declarative 3D for the Web Architecture

Posted by PL   |   Filed under: 3D

The Dec3D2012 workshop will take place on Tuesday morning, April 17th 2012, Lyon, as part of WWW2012 Meeting.
The aim of the workshop is to encourage researchers from both the Web and 3D graphics communities to meet and talk about an integration of interactive 3D graphics capabilities into the Web technology stack. The goal of the workshop is to provide a forum for the communities, in which participants can:

  • Present and discuss approaches to publishing 3D graphics on the Web in a declarative way;
  • Discuss how the general principles, that are/were valid for the Web, translate to 3D declarative graphics, what are the difficulties, how can that goal be achieved in the current ecosystem of web development;
  • Explore how the incorporation of declarative 3D graphics can be done in currently popular web browsers; we expect to showcase innovative applications that deeply integrate 3D graphics and HTML, among others, Fraunhofer and DFKI will report on X3DOM and XML3D as models for an easy to use 3D hypermedia publishing frameworks;
  • Shape the agenda and identify upcoming research issues for the next development stage of the 3D Web.
The program of the workshop is here.

Developing Web Applications with COLLADA and X3D

Posted by PL   |   Filed under: 3D

This whitepaper is intended to assist developers in understanding the similarities and differences between COLLADA and X3D, the design goals that informed their development, and how and where the two standards are used in practical applications. Rather than making a decision between the two technologies, many implementers will find that COLLADA and X3D can be used together as a powerful tool set for developing their Web and enterprise applications.
Authors: Dr. Rèmi Arnaud (Sony Computer Entertainment) and Tony Parisi (Media Machines, Inc.)

Temporal Database Applications

Posted by PL   |   Filed under: database

This whitepaper is focused on methodologies for manage manage time-varying data in databases. This article show different approaches that have been introduced for developing time-oriented database application, on top of existing DBMS technologies. Then, authors addressed several issues concerning developing a technique that enables database designers to understand the way in which time-varying behavior can be modeled and mapped into tabular form.
