Workshop on Image and Audio Analysis for Multimedia Interactive Services
Telecom ParisTech, Paris,
France
3-5 July 2013

WIAMIS 2013, the Workshop on Image and Audio Analysis for Multimedia Interactive Services, is a major event in the multimedia community, offering the possibility for researchers and developers to exchange ideas on issues linked to interactive services. This 14th edition, paid particular emphasis to audio analysis and audio-driven multimedia analysis research.

On the second day of the workshop, from 15:30 – 17:00 in the EU project demo session, Paul Chippendale presented a live VENTURI interactive demonstration which attracted a great deal of interest from the attendees.

It illustrated the integration of results coming from the first steps of the project and consisted of a software and hardware technology showcase woven into the form of an AR game experience on a table-top 0.8m x 0.8m miniature city. One player has to accomplish a set of missions (i.e. burger deliveries in a limited time), by steering a virtual car with a mobile AR device through the real city. Spatial 3D audio effects add to the immersive experience of the game, The demonstration showed state-of-the-art real time markerless 3D tracking on a mobile device. In order to deliver a ‘nailed down’ AR experience, the pose (or 6 -DOF) of the device, with respect to the 3D city model, is estimated at 20fps. Visual feature extraction/tracking and advanced hardware sensor data fusion algorithms were exploited to provide a high level of robustness and performance.

Mobile World Congress 2013

March 1st, 2013 Comments off

The VENTURI project was again present at the Mobile World Congress 2013 (Feb 25-28, Barcelona, Spain). Oliver Ruepp from consortium partner metaio presented the VENTURI first year demonstrator at the ST Ericsson public Booth. This was a major visual enhancement, as compared to the earlier demonstrator at MWC2012, as it showed the correct handling of occlusions between real and virtual objects. This was made possible by geometrically reconstructing the city in an offline stage and using the resulting 3D models for occlusions.

The demo ran on the experimental prototype mobile platform from VENTURI partner ST Ericsson, showcasing sensor-aided markerless feature-based tracking, including Hillcrest Labs’ Freespace sensor fusion technology for enhanced tracking stability and robustness.

State of the Map 2012

State of the Map 2012 – SotM2012
The 6th Annual International OpenStreetMap Conference
Tokyo, Japan, September 6th – 8th, 2012
Attendee: Jacques Lemordant (INRIA)

The subject of the presentation was navigation using MEMS sensors and the title was From Web to Urban Navigation.

Jacques Lemordant (INRIA) presenting at SotM 2012

The Open-data movement exemplified by OpenStreetMap, aims to exploit MEMS sensors in mobile phones (accelerometers, magnetometers, gyroscopes) to create practical Augmented Reality technologies. This drive, enabled by the increasing capabilities of our mobile phones, will change the way we think about traveling through our cities, thanks to the increasing availability of real-time urban information systems and personalisable on-board geographical information.

GPS navigation systems, when used in an urban environment, are limited in precision and are only capable of providing instructions down to street-level and not of sidewalk-level. As GPS is limited to outdoor navigation, a delicate transitioning system is required when switching to another positioning system for indoor navigation.

In Jacques’ presentation, he talked about VENTURI’s work in the field of pedestrian navigation for blind users. Traditionally, pedestrian navigation systems are built around the Inertial Measurement Unit (IMU) of mobile devices, harnessing on-board geographical data through a routing engine. A precision accuracy of two or three steps can be obtained, with user feedback being done through a mix of spatialized vocal instructions and 3D audio. The distinction between indoor and outdoor navigation is blurred as an IMU-based location engine can run indoor and outdoor. audio-based Augmented Reality queries on nodes or POIs, and ‘ways’ and ‘relations’ can be predefined for efficiency, suitability and quality of information motivations.

ISMAR 2012

November 20th, 2012 No comments

At ISMAR 2012 (Nov 5-8, Atlanta Ga, USA), Selim BenHimane (metaio) hosted a demo area dedicated to the VENTURI City game.

The demo presented a multi-player Augmented Reality game that takes place on a table-top. The players have to accomplish a set of missions in the city (deliveries in a limited time, fire extinguishing, etc.). The real-time visual localization employed in this demo was based on the tracking partly described in the ISMAR 2012 paper by Kurz et al. “Representative Feature Descriptor Sets for Robust Handheld Camera Localization”. The demo ran on the experimental prototype mobile platforms from ST Ericsson. The system showcased sensor-aided markerless feature-based tracking. The virtual appearance of the city was geometrically reconstructed in an offline stage for the correct handling of occlusions. A continuous communication between the mobile platforms permitted multi-player interaction.

This demo is the result of the first step in the project that consists of the integration of the technology, the software and the hardware to showcase an indoor multi-player AR game.
