Participatory Design Meets Mixed Reality Design Models

Participatory design and model-based approaches are two major HCI design approaches. Traditionally opposed, the first ones promote user’s creativity while the second ones support a more systematic approach of the design space. In Mixed Reality domain, combining these two aspects is especially crucial in order to support the design and to help the users to take into account the wide variety of emerging technologies. We introduce in this paper a solution to bring these two approaches together. In addition, we illustrate how the outcomes of this combination of formal and informal approaches serve as input for the implementation of the designed solution

Observation and capture of multimodal interaction in mobile situations

This paper describes a method and a data collection infrastructure for capturing data about the use of a mobile multimodal system in the field, under realistic conditions. The infrastructure includes instrumentation worn by the user to capture his perspective while moving, a means of capturing a wider view of the context and a multimodal data logger.

Co-conception d'expériences interactives augmentées dédiées aux situations muséales

This paper shows the different steps of a co-design process dedicated to build augmented interactive experiments in Museums. This process enables an analytic framework listing the different dimensions to tackle during the design of augmented interactions. These different steps are illustrated by a case of study in the classification of life.

Etude empirique de l'interaction multimodale en mobilité: approche méthodologique et premiers résultats

This paper sums up the first results of an empirical study on the use of a multimodal device in mobility in the context of a collaborative game. The main features of the data gathering and analysis platform is described, then some results on the use of multimodality are presented.

Instrumentation de focus-group dans la co-conception de systèmes mixtes

This paper introduces and illustrates a process that integrates Focus-Group into early phases of a mixed systems design process. This process supports the systematic exploration of mixed interaction design solutions and offers a framework to present data collected in a Focus-Group. We also present a connection between this process and an existing tool for the design of mixed systems.

Experimental studies of a graphical authentication system based on semantic categorisation

This article sums up results from two experimental studies conducted in the context of a research project on the design and assessment of a graphical authentication system (HSA® for Human Semantic Authentication). The three experiments address different issues related to the usability of the system (performance), and its cognitive demands (memorisation and categorisation). The results put into evidence that, despite the fact that this type of system presents some advantages in terms of use (providing some requirements are observed), it raises nonetheless different problems which put uncertainty on its potential acceptabilty and use in real world situations. The results illustrate the traditional tension between security and usability.

Etude exploratoire des usages d'une application sociale mobile

This paper investigates issues related to the use of mobile social applications which aim at supporting coordination and communication, and enhancing the feeling of connectedness and social presence. To explore these assumptions, we conducted an empirical study of an application that enables group of users to share awareness information about their status and location. We present the results of the study, focusing on three issues: patterns of usage of awareness information, evolution of the usage, and privacy.

SIMBA: méthodologie et plateforme de prototypage moyenne fidélité pour les systèmes interactifs mixtes

In this paper, we present SIMBA, a prototyping approach dedicated to Mixed Interactive Systems (MIS). This approach supports the use of an existing co-design process of MIS. SIMBA combines a «medium fidelity» prototyping platform based on simulation, and a model-driven development process. Simulation-based prototyping allows for a fast and inexpensive generation of mixed interactive prototypes. A model-driven development process enables such prototypes to be tightly coupled with design choices established in earlier design phases. It also supports an incremental evolution into the final, not simulated, MIS. The prototyping approach that we present is based on the identification of the roles of the different actors involved in a MIS development process and the collaboration between them. An augmented museum application is used throughout this paper to illustrate the proposed prototyping approach.
