Conception, développement et évaluation de techniques d'interactions fluides pour des environnements multidimensionnels : application aux logiciels du service public

Abstract : The work of this thesis is part of a collaboration with the company Berger-Levrault, a major actor in the development of administrative management software for public services. This work is based on two observations. On the first hand, the policy of digitization of public services induces the need for software adapted to the professions of all public institutions. These software are complex and particularly rich compared to classically used office software (Office, mailbox, etc.). On the other hand, we observe that the devices used to interact with these software did not evolve. Since several decades, the mouse and the keyboard remain the norm in a fixed environment. However, these devices have only few input degrees of freedom. The manipulation of multidimensional data with these devices induces a greater number of steps to perform a task, thus lengthening the interaction path. In this context, the objective of these thesis work is to improve the interaction flow with multidimensional data contained in the software of the public service through the increase of the input degrees of freedom proposed by the devices. Indeed, a larger amount of input degrees of freedom would reduce the number of steps necessary to the accomplishment of a given task, thus improving the interaction flow. We propose three major contributions: a device with multiple degrees of freedom, the Roly-Poly Mouse; a design space, DECO; as well as a set of interaction techniques with mobile devices based on the principle of stacking. A first contribution of our work is the design of a new device with multiple degrees of freedom: the Roly-Poly Mouse (RPM). This device, whose base is rounded, aims to replace the traditional mouse. It has 6 degrees of freedom (3 translations of which 2 exploited and 3 rotations). We evaluated its performance and compared it to other devices for a task requiring 6 degrees of freedom (3D object manipulation). A second contribution of our work is the definition of a design space focusing on the physical aspect of the composition of devices: DECO. DECO relies on two axes: physical arrangement and physical manipulation. From this design space, we designed a compound device: the Roly-Poly Mouse 2, a device consisting of the combination of a Roly-Poly Mouse and a traditional mouse. We evaluated its performance and compared it to other devices through a RST task (Rotate-Scale-Translate, 5D task). [...]
