Research Abstract:
Standing at the conceptual intersection between various fields (i.e., Communication, Human-Computer Interaction, Consumer Behavior, Social Psychology, and Usability), this research investigates the influence of social functionalities on consumers’ online attitude toward contributing content to the website. Relying on social psychology theories such as group influence and similarity-attraction, one of our central predictions is that when online consumers are exposed to Web sites containing features supporting the site sociability, their attitude toward contribution will be greater than when not exposed. Furthermore, galvanic skin response was used to assess emotional response during the task, to complement more traditional data collection methods. Our results show that online consumers’ attitude toward contribution is positively influenced by social functionalities, and that emotional reactions mediate this influence.

14 / 07 / 2009Search Interfaces: Usable Guidelines and references

“Hearst’s brilliant organization, lucid writing, and admirably comprehensive review … are gifts to scholars, implementers, and students who want to contribute to … user interfaces for information search and retrieval.” – Dr. Ben Shneiderman

When books in a research field can specialize as much as to focus on guidelines for a specific applied context: that’s a clear sign of maturity! Yes! Usability has become a mature field of research and practice! And here are the evidence!

The kind of maturity I am refering to here -for usability as a research and practice field- is linked to but different from what Jakob Nielsen suggested for the corporate environment with his 8 stages of Corporate Usability Maturity.

Search User Interfaces
is a new book by Dr. Marti Hearst, professor in the School of Information at the University of California, Berkeley (BA, MS, and PhD degrees in Computer Science). She was a Member of the Research Staff at Xerox PARC from 1994 to 1997.

Published by Cambridge University Press (50 US$), this book is also sold through Amazon (40 US$), and very surprisingly available for free online. (In the book’s blog, you can read how the author managed to convince the publishor to do such thing!)

It is recommended to start with the Preface, which gives an overview of the book’s contents which offers two main parts: Search fundamentals (Chapters 1-7) and advanced topics (Chapters 8-12)such as Chapter 8 which tackles Navigation and Search for instance. I particularly enjoyed the chapter dealing with emerging trends in user search interfaces, exploring mobile search and social search.

Beyond its practical reach, the book is filled with references to human-computer interaction papers.

I first heard of this book via a post by Alexandre Huete on the Ergo-IHM list on July 4th, 2009. Thanks Alexandre!

12 / 01 / 2006Theories used in IS (Information Systems) Research

Bonne année à tous mes fidèles lecteurs et passionnés d’ergonomie cognitive !

Pardonnez mon silence depuis la mi-décembre…entre les travaux de recherche doctoraux de fin de session, le sapin à monter avec les cadeaux de noël à courir, les partys de famille…et quand même un peu de repos…me revoilà en pleine forme avec une perle rare pour démarrer l’année en beauté et me faire pardonner !!!

Il s’agit d’un site de référence à bookmarker absolument les amis!

Il y a là une mine d’or pour nos travaux de recherche tout comme pour nos justifications de solutions dans les mandats pour l’industrie. Il s’agit du site de l’AIS (Association for Information Systems) de l’Université York de Toronto.

Ce site regroupe toutes les théories qui existent relativement aux systèmes d’information, de la célèbre théorie de l’Acteur-Réseau de Bruno Latour à la plus classique des classiques des théories dans notre domaine…the Information Processing theory ! Descriptions sommaires des fondements et concepts clés, schémas, références de la littérature, liens complémentaires,…bref tout est là !!!!

Enjoy folks ! Avouez que ça commence bien l’année 2006 non ? :-)

P.S.: Un gros merci à mon camarade Momin Mirza de McGill du cours IT Acceptance and Usage.
