I’m very glad to have two articles accepted for presentation at the 19th International Conference on Information Visualisation, which will take place at the University of Barcelona on July 22-24th 2015.
The first article is titled “The Design Process: A Visual Model.”
Abstract: “Knowledge visualizations are often created by practitioners and managers, not necessarily by expert graphic designers. Non-experts – as well as novice designers – can be puzzled and overwhelmed by the complexity of the design process: it is unclear how to start and which are the main phases and their sequence. Often times even experienced designers mistakenly start by selecting a tool or a solution, instead of considering the audience and its needs. The aim of this conceptual piece is to assemble the main phases (and related procedures and tools) of the design process to provide a pragmatic visual guide for students and practitioners. It also highlights the highly cyclical nature of designing through a structured iterative process of prototyping and testing. The model can be utilized for a broad spectrum of applications, including the creation of knowledge visualization, information visualizations, graphic design or other types of product. The examples provided in this paper are specifically related to knowledge visualization.”
The second article is co-authored with Marta Perez Garcia,of the Birmingham City University. We discuss “The Role of Visual Templates on Improving Teamwork Performance.” by giving evidence both from lab experiments and from field work.

Yesterday April 28th 2015 the Impact Investing and Social Finance Conference 2015 took place at the University of St. Gallen.
It has been a remarkable event in which impressive spekers presented thier cases and opinions on the topic of Social Impact Investment, especially in the context of Latin America.
The conference was organized by the Impact Investment organizing team: more information about the IILA Knowledge Platform, for which I’m very gladly part of the academic network, can be found at thier website: http://www.impactinvesting.com.br/

Today we start the second part of Module 5 on Linguistics and Semiotics at the Università della Svizzera italiana, for the Executive Master of Advanced Studies in Intercultural Communication.
Here you can find the presentation of the course:
I’m looking forward to meet again the MIC 7 group!

I’m very honored to have all my 3 papers accepted at the next Academy of Management meeting in Vancouver this August 2015!
The first paper is: “Intercultural Groups and Visual Collaborative Systems: Increasing Structuring to Improve Precision.” written in collaboration with Alice Comi of Aalto University, Finland. In this paper we present the results of an experiment in which groups of 5 managers from different nationalities worked together. Our results show, as predicted, that when a digital visual template is provided, both nationally homogeneous and nationally diverse groups perform better than when no visual support if provided.
The second paper is “The Effect of System-embedded Visual Restrictiveness on Experience Sharing.” co authored with Alexander, E., and Eppler, M. J. has been selected as best paper and will be included in the conference proceedings. The study examines the effects of visual restrictiveness on group process and outcome and finds that a medium level of visual restrictiveness leads to significantly better performances compared to no support or to a highly restrictive system.
The third paper is “A Visual Re-Play Methodology for Group Discussion Analysis.” co-authored with Elitsa Alexandered and Martin Eppler, reports an innovative mixed methods methodology for the analysis on group discussion through the replay of screen captures.

At the University of St. Gallen we just had a presentation on IBM Watson, the impressive 3000 core technology developed by the IT giant.
My favourite application of Watson in the healthcare field and can be seen in the picture below: Watson helps doctors and hospitals identify patients illnesses based on symptoms and personal history (which includes all medical records of the patient). Watson “cognitive” abilities are really impressive: you can type the patient symptoms and in less than a second Watson proposes a list of illnesses. The doctors can then improve the system by giving “feedback” to Watson, which in turns learns to improve its predictions. Very impressive! I can already imagine very useful apps in healthcare to support healthcare staff in remote areas of the world and in particular for the poorest patients who cannot afford to travel to hospitals to get a medical checkup.

Our research on Extending TAM to Information Visualization: A Framework for Evaluation is forthcoming in the Electronic Journal of Information System Evaluation.
Studies on the evaluation of information visualization techniques are flourishing, and related methodologies have been discussed in a growing number of recent studies. Yet, these evaluations concentrate mostly on usability measures and cognitive evaluations. In contrast, this contribution focuses on the various factors that drive the adoption of information visualization techniques. The Technology Acceptance Model and the Diffusion of Innovations theory are deployed to develop a framework for evaluating information visualization adoption. These seminal theories are extended and adapted to Information Visualization, resulting into a framework with three main dimensions: perceived ease of use, perceived usefulness, and perceived authority. The application of this theoretically-based evaluation framework is illustrated through positive and negative examples. As many visualization solutions have not achieved a wide use, the question of which factors foster their adoption seems to be a particularly relevant yet under-researched topic.
