Demo 1: Video-Based Demonstration: Hands-Free / Eyes-Free Support for Mobile Equipment

Authors: Max Mühlhäuser, Dirk Schnelle, Erwin Aitenbichler, Jussi Kangasharju
Affiliation: Technische Universität Darmstadt, FB20-Telecooperation;

Abstract: We have studied one of the three large application areas of Talking Assistants (TAs) in the automotive field (besides car manufacturing and driver/passenger support): supervisor & technician support at service stations / carshops. The results of these studies have been combined

into a running demo of structured audio information retrieval (Stairs) enabled TAs, showing their use by several employees during the process of automotive maintenance, from customer arrival through pick-up of the repaired car. The demo was built using MundoCore, a distributed development environment with ubiquitous middleware, support for 2D and 3D world models, distributed debugging, a unified distributed programming paradigm (for Java and C), support for vertical migration from large to very small footprint nodes, and more. Presented as a video, it demonstrates TAs, Stairs, and the Stairs navigations structure with the added use of IR-based tags and badges.

Abstract:  This demo system consists of the Profile Aggregator (PA), profile management server, and a mobile terminal equipped with a RFID tag reader. Profile gathering software has been developed on the mobile terminal and the functions at the PA have also been developed. The runtime in the PA is acceptable for running a shopping navigation service. In this demo, the shopping navigation service and the visualization of the user profiles aggregated from several sources are demonstrated. In the current implementation, the overall history of the user’s activities has been preserved.


Demo 3: Context-Aware Content-Provision Service for Shopping Malls or Department Stores Based on Ubiquitous Service-Oriented Network Framework

Authors: Michiharu Takemoto* and Takeshi Okuda**

Affiliation:  *NTT Network Service Systems Laboratories, NTT Corporation

Abstract: This is a context-aware content-provision service, and the content is assumed to be commercial advertisements in a shopping mall. It is like the automatic “audio-guide services” in museums. The system detects the context, determines suitable content for the context, and provides the content to the user through an output device suitable for the context. Here, the context includes present information and attributes of the user, and content from the shops. The system determines the content and display devices, and it invokes the display devices using a content-showing operation. The invocation mechanism is achieved with our proposed service-provision framework, which is called the Ubiquitous Service-Oriented Network (USON).


Demo 4: Zig Zag: Tactile Handheld Navigation Platform

Authors: John Miller, PhD, Javier Rodriguez Molina, Tracy Woo and Kyle Tarpalee

Affiliation: Calit2

Abstract: The Zig Zag is an RF transmitter/receiver analog device. It is composed by a 3 channel FM 2 stick radio transmitter which sends the signal to an analog module box. The receiver standing inside the analog module box feeds the signal to the RC Switch (35 RAM). From here, the input received gets modulated in order to output the necessary square wave signal. The signal leaves the analog module through a DB9 connection to reach the hand-held box consisting of a HS 322 servo and a vibrating motor. This last box will be the output of our system. The servo will point to the direction indicated by the transmitter and the vibrating motor will go off signifying that the final target location has been reached or the necessity of an immediate stop.


Demo 5: "511" traffic information service

Affiliation: Calit2

Abstract: This next generation mobile Traffic Notification System allows first responders as well as the general public to get real-time traffic information through their cell phones. The system we have developed allows for on-demand, anytime anywhere access of traffic information through any phone. It provides you with highly personalized traffic reports including commute time based on the current traffic conditions and fastest route to your destination based on the current traffic conditions. No other system can provide such personalized information on demand, today. This system currently has over 5000 registered users and receives about 30,000 calls a month. The system is capable of dynamically changing voice prompts to accommodate special announcements from the Police Department. The police used the system to get access real time traffic information from the field and also to communicate between the fleet through the special announcements feature. The system is available via the toll free number (866) 500-0977 and its associated web site is


Demo 6: Cellular Platform for Location Tracking

Name: John Zhu

Affiliation: Calit2

Abstract: The system is built with latest Assisted GPS(AGPS) technology.  Based on AGPS, a mobile phone is used to track the position and speed of objects, e.g., campus bus. A real-time map is provided to view of location, speed, and identity of objects. The GPS tracking is done via a commercial cell phone instead of a separated GPS device.  AGPS is the combination of GPS and Mobile Technology. It is small and embedded inside mobile. It works indoor and outside and the cell phone is integrated with AGPS, voice and data capable of performing lots of smart applications.

Demo 1: Proxy-based Hand-off of Web Sessions for User Mobility – Tool demo presentation

Authors: G. Canfora, G. Di Santo, G. Venturi, E. Zimeo, M. V. Zito

Affiliation: RCOST - University of Sannio via Traiano, 82100 - Benevento, Italy

Abstract: A proxy, called MuffinSH, is presented that was built by extending a filtering system, Muffin (, freely available under GNU General Public License, and supports HTTP/0.9, HTTP/1.0, HTTP/1.1 and SSL. MuffinSH uses the filters inherited from the Muffin interfaces to implement a session hand-off. The main interfaces implemented by MuffinSH are: RequestFilter, ReplyFilter, ContentFilter, HttpFilter, and RedirectFilter. The proxy is installed on a PC. The demo will show a session connection, through MuffinSH, to some well-known web sites, such as, by using the web browser installed on the PC. After the navigation the browser window is closed and the session will be continued by using a PocketPC.


Demo 2: USHA: A Practical Seamless Vertical Handoff Solution

Authors: Ling-Jyh Chen, Tony Sun, Mario Gerla

Affiliation: UCLA Computer Science Department, Los Angeles, CA 90095, USA

Abstract: In this demo, we demonstrate Universal Seamless Handoff Architecture (USHA), a simple handoff solution that satisfies the requirements for seamless handoff. Compared to other seamless handoff solutions, USHA is simple and requires minimal changes to the current Internet infrastructure. Therefore, it is instantly ready for real-world deployment. We show USHA by observing TCP (FTP downloading) and UDP streaming behavior during vertical handoffs. The demo shows that USHA can successfully maintain the application connectivity in all cases.
