Girardin, F., Boursinou, E., Moghnieh, A., “Convince Woody”, a serious game on competence development in a distributed collaborative environment

Abstract: In this paper, we present the adaptation of a serious game in the context of an e-learning framework supporting distributed social networks. The game, “Convince Woody” takes stage in the digital movie production highlighting the problem of managing the competence development dimension involved in interdependent yet highly spread organizations. Our first objective is to demonstrate the utility of serious games in complex cooperative environments and converge on the provision of a suitable environment for validating and evaluating informal learning perspectives in an e-learning framework. Secondly, the pilot will prove a state-of-the-art environment for revising remote collaboration from an asynchronous communication perspective in order to evaluate the relevant tools’ efficiency in responding to the needs of our scenario. Lastly, we plan to explore the use of synchronous and asynchronous collaborative tools to maintain the flow of information, the interaction and the cooperation.

Common Models and Patterns for Pervasive Computing Workshop (CMPPC '07)

The Common Models and Patterns for Pervasive Computing Workshop will take place at Pervasive 2007 in Toronto, Ontario, Canada, May 13-16, 2007. The goal of CMPPC 2007 is to provide a forum to identify and address the issues to continue the rapid rate of progress and facilitate the wider deployment of pervasive systems. The workshop topic “Examples of pervasive systems used and supported by multiple projects and research groups avoiding reinvention and rework” provides me the opportunity to submit a paper on the development, deployment and run of EPFL’s CatchBob! and UBC’s The Fugutive.

Relation to my thesis: For quite some time now, I have been looking for the opportunity to write a workshop paper on CatchBob!

Heat Map of Barcelona Geotagged Images

Based on the data from “Location Granularity of Images in Flickr” and GeoIQ API. Unfortunately, GeoIQ does not seem to handle more than 500 locations, so I had to trim the data and remove the locations where less than 2 and more than 20 picture were taken. Applying a clustering algorithm could be a workaround for that constraint.

The whole city, with hotspots in the city center, Parc Guel, Sagrada Familia, and the whole Passeo de Gracia avenue.

The city center with hotspots at the Cathedral, Plaza Catalunya, the whole Rambla, Plaza Real, Born, and Museum of Art (MACBA)

Location Granularity of Images in Flickr

I am using Flickr to investigate the granularity of the position the users attach to their images in relation to where they have been taken. Here an example based on 5543 retrieved images with the tag “barcelona” and granularity 16 (i.e. street level. World level is 1, country is ~3, region ~6, city ~11, and street ~16).

Related to Granularities of User Experience in Ubicomp.

Relation to my thesis: Pet project in the 1-2am shift. Actually, exploring the different levels of location granularity used in the Flickr community could become an example that show where location accuracy is used in a urban space. Next steps, using the descriptions/tags of the images and exploiting GeoIQ.

CHI 2007 Workshop on "Mobile Spatial Interaction"

The Call for Participation for the CHI 2007 Workshop on “Mobile Spatial Interaction” is out.

The idea of Mobile spatial interaction (MSI) is becoming increasingly relevant, feasible and desired. Location and orientation sensing hardware is being integrated into a growing number of handsets and can be expected to be even more widespread in the near future. At the same time, geographic information systems and 3D models are becoming more sophisticated.

The workshop Mobile Spatial Interaction will aim to help researchers realize the vision of seamless and intuitive Mobile Spatial Interaction. The goal is to reach beyond the conventional model of location by creating a sense of space and orientation.

Original research results and concepts on the following topics are encouraged:
- Methods and ideas for the identification of application scenarios
- Modelling concepts for geo-spatial (end-user) content creation
- Conceptual designs and scenarios of spatially-aware interaction techniques
- Outdoor testing methods for spatially aware applications
- Augmented/parallel reality concepts in gaming, arts, tourism, etc
- Location/orientation sensing technologies and migration paths from legacy to state-of-the-art technology
- Mobile social applications and services involving the interaction with information created by other users
- Indoor navigation and spatial awareness
- Practicality and feasibility issues regarding technologies, application design and data modeling.
- Combination of spatial interaction with gesture-based interaction
- Dealing with sensor uncertainty e.g. what happens when GPS shadows occur or there is less accurate wireless transmitter triangulation?
- Multimodal integration, e.g. by adding spatial audio, touch, or scent

Relation to my thesis: A must submit workshop!

Bricks for a Urban Location Aware System

I am using different positioning techniques (GPS, WiFi and GSM) to investigating the fluctuating location quality and timeliness experienced in a large-scale coverage such as the Barcelona urban area.

(from left to right) Using a homemade S60 Application to collect GSM fingerprints in specific POI such as metro stations, WiFi map (courtesy of Yuji Yoshimura, Agencia d`Ecologia Urbana de Barcelona), GPS drifts in of of the many compact low-rise buildings area of Barcelona.

Relation with my thesis: toying around to come up with design ideas and contexts for their implementations.

Mobile LBS Market

Presented at the LIAISON-ISHTAR Workshop in September of this year, Mobile LBS Market by C. Desiniotis, J. G. Markoulidakis from Vodafone, and J-Fr Gaillet from NAVTEQ presents the reasons for the low adoption of LBS during the past years as well as the drivers that are expected to push the still emerging LBS market in the near future.

The authros first define the different aspects of positioning techniques such as access technology, measurement, terminal vs. network based, indoor vs. outdoor, and software/hardware implications. Positioning techniques performance can be evaluated using criteria such as accuracy, latency, availability, reliability and applicability. In fact, the achieved positioning accuracy is closely related to the implementation costs.

More interesting, they provide a classification of 18 mass-market LBS applications with their different needs in terms of required quality of service (accuracy, integrity, indoor coverage, etc.) and the different groups of users they address

The reasons why LBS is not yet the “killer application” in wireless communications are a combination of reduced take-up of mobile data services as a whole, and low take-up specifically of mobile LBS. Some of the most important reasons responsible for this turn are summarized as follows:

• Poor tracking performance
• Inherent customer perception issues
• Low throughput mobile networks
• Significant investment required
• User adoption requires time
• Not well defined business models
• Unfriendly User Interfaces

They conclude that:

Technology hype and low adoption of the existing model of LBS (first wave of services) lead the market to rationalise and refocus. It is evident that users lacked of interest in the existing offer during the past years. The expectations for the second wave of LBS should thus be more conservative in terms of the market growth.

Relation to my thesis: The paper concurs with the many discussions with Nicolas about the failed state of LBS and the expectations of a second wave (i.e. “how LBS failed as a technology-driven product but how it was a success in the dissemination of such applications in people’s mind”). I am not sure the “drivers” mentioned in this papers are the key for the take-off of a second wave of LBS. Indeed, users still do not seem to be in the center of preoccupation of LBS practitioners and analysts.

In my work, I acknowledge poor tracking performance and low throughput mobile networks as potential initiator of issues on the usability of a location-aware application. However, I do not consider that improvements in positioning techniques and data communication as the unique key factors for a usable application. I investigate the management and integration of the technological constraints in the design of the system.

The LIASON Project – Bringing Combined Positioning and Communications Technologies to Market

LIAISON is a 3.5 years initiative with 30 partners from 10 European countries to develop and implement a new generation of location-based services (LBS) for the professional market. The project approach, based on what is called ‘enhanced assisted GPS’, is designed to improve the speed, accuracy and reliability of existing GPS systems, allowing a whole new range of time, cost and life-saving services to be developed. The key difference between the enhanced assisted GPS being implemented by LIAISON and standard GPS is a ‘”substantial” improvement in every aspect of the location-based services, the coordinator notes. By combining GPS with an external server to refine the raw location data, LIAISON can pinpoint a person’s location to within one or two meters. Even more importantly, a user can pick up the signal and identify their location within seconds, not minutes, and the system works even in the most challenging environments, such as in urban canyons surrounded by high buildings or in dense forests.

The first tests involve deploying location-based services to aid remote workers for French broadcast service provider TDF, and also to enhance data collection for Ama, a waste management company in Rome. The second set of trials, which are scheduled to begin May 2007, entail assisting maintenance workers for Spanish electricity supplier Endesa, and operating an automated dispatch system for taxi drivers in Greece. In the third test phase, beginning January 2008, LBS will be implemented for the Sussex police force in the United Kingdom and for fire fighters in Italy.

A workshop has been held in September 2006 (proceedings).

Relation to my thesis: A big european project to improve speed, accuracy and reliability of LBS. The efforts are concentrated on professional applications rather than the public. I particularly like the Rome test on enhancing data collection of a waste management company. Even if the use of location information are different in each test, the core components of the system remain the same. It does not seem that the projects aims at covering my research question: “how certain (accurate) do positional and tracking systems have to be in order to be useful and acceptable?”.

I hope the outcome of the project will surpass the current louzy italian-based project web site.

Defining Usability, User Expericence, Utility, and Usage

Some of the feedback I receive on my research plan highlight my misuse of the terms usability, user experience, utility, and usage. Sara Ljunblad’s User Driven Design course provide some clarifications.

First of all HCI aims at developing or improving the safety, utility, effectiveness, efficiency, and usability of systems that include computers (Interacting with Computers, 1989, p. 3). Utility refers to the functionality of a system and usability is about making systems easy to learn and easy to employ.

Usability can be broken down into the following goals:

• Effective to use (effectiveness)
• Efficient to use (efficiency)
• Safe to use (safety)
• Have good utility (utility)
• Easy to lean (learnability)
• Easy to remember how to use (memorability)

Interaction design aims at creating user experiences that enhance and extend the way people work, communicate and interact. It shares the same fundamentals as HCI in terms of usability goals and design methodology, but it is also concerned about creating systems that are:

• Satisfying
• Enjoyable
• Fun
• Entertaining
• Helpful
• Motivating
• Aesthetically pleasing
• Supportive of creativity
• Rewarding
• Emotionally fulfilling

Usage is the act, manner or amount of using.

Relation to my thesis: I do not investigate in the field of user experience as its scope is very large and highly subjective therefore difficult to quantify and evaluate in a scientific way. I mention “enhance the usability of location-aware system” as a very abstract goal. This might need to be reformulated.

New Experiments with ShoutSpace

ShoutSpace is an application for collaborative annotations of a map in a nomadic setting (Stamps being the mobile version), I developed with Mauro Cherubini at the Swiss Federal Institute of Technologies Lausanne (EPFL). This week, we modified the system for Mauro to run experiments in fixed settings with a very specific task and 3 experiments conditions. The first where participants can communicate using a standard chat utility. The second where participants enrich the conversation with spatial information and finally a mixed condition where they are free to use a standard utility or the spatialized one.

The three experimental conditions

Relation to my thesis: Mauro’s work over the years has given me lost of insights on spatial annotations and how to run experiments in mobile settings.
