<p>In Alzheimer association’s clinique practice, there was a need to communicate with people with mild dementia. Videophone is considered as one of the best assistive communication tool for these people since video communication is not only a tool to break an isolation caused by the disease, but also a powerful way to help people demonstrate their ideas and understand what is said in a conversation with pictures, signs and body language. Therefore, an easy-to-use videophone for people with mild dementia is needed.</p><p>The goal of this master thesis is to design a graphical user interface (GUI) of an easy-to-use videophone for people with mild dementia according to their characteristics and difficulties of using everyday technology. User centered design (UCD) was used in the design. To get familiar with the user, literature research was conducted before design.</p><p>Low-fidelity prototype was created. With the help of Karolinska institute’ research group on people with dementia, the prototype was refined twice. Based on the refined low-fidelity prototype, an interactive prototype with navigation, sound and animation effect was created. A usability testing was conducted on older adults with this interactive prototype.</p><p>In addition to the GUI of functions for people with mild dementia, GUI of functions for other care givers was also created and presented in this master thesis.</p>

This thesis is devoted to the study of a deformable material interface between two immiscible moving media, both of them being magnetizable. The first part concerns the establishment of a complete set of dynamical equations allowing a complete description of the non equilibrium phenomena including a coupling between the internal angular momentum and the electromagnetic field. The effects of the relaxation processes are also discussed. We show that the deformation of the interface introduces a nonlinear term, proportional to the mean curvature, in the surface dynamical equations of mass momentum and angular momentum. That term intervenes also in the singular magnetic and electric fields inside the interface which lead to the influence of currents and charge densities at the interface. In a second part, we give the expression for the entropy production inside the interface as well as in the bulk phase. Using the general principles of non equilibrium thermodynamics, we compute the different thermodynamical fluxes.

The goal of this master thesis is to design a graphical user interface (GUI) of an easy-to-use videophone for people with mild dementia according to their characteristics and difficulties of using everyday technology. User centered design (UCD) was used in the design. To get familiar with the user, literature research was conducted before design. Low-fidelity prototype was created.

Lacome is a multi-user cross-platform system that supports collaboration in a shared large screen display environment. Lacome allows users to share their desktops or application windows using any standard VNC server. It supports multi-user concurrent interaction on the public shared display as well as input redirection so users can control each other's applications. La-come supports separate types of interaction through a Lacome client for window management tasks on the shared display(move, resize, iconify, de-iconify) and for application interactions through the VNC servers. The system architecture provides for Publishers that share information and Navigators that access information. A Lacome client can have either or both, and can initiate additional Publishers on other VNC servers that may not be Lacome clients. Explicit access control policies on both the server side the client side provide a flexible framework for sharing. The architecture builds on standard cross-platform components such as VNC and JRE. Interaction techniques used in the window manager ensure simple and transparent multi-user interactions for managing the shared display space. We illustrate the design and implementation of Lacome and provide insights from initial user experience with the system.
