User experience

Yesterday I did the last step in my Media Informatics master endeavor: I presented my master thesis. After quite a few months of development on the Microsoft Surface, the application that resulted was a good start for a (possible) commercial product. We started from the idea that a multitouch table device […]

Breiny – Master thesis application

Overview of my Master thesis, it summarizes the work by presenting the contributions to the research field and also the future work based on the already created prototype. The Breiny application is meant to support the Brainstorming process by using computers in a modern way – Natural User Interface. After creating the prototype, a User Evaluation was used to prove or disprove the theoretical hypotheses

Master thesis – Conclusions

The Evaluation session started with the Prototype presentation. This was targeted only on the User Interfaces, explaining how and which actions can be performed with each area of interest (UserControls and Main SurfaceWindow from Implementation Chapter). The users were encouraged to experience the interface and ask questions during the presentation, in order to understand better the interaction with the prototype.

Master thesis – User evaluation

The theoretical evaluation of the thesis work starts with by assessing in which measure the research questions were answered by the proposed concept. Then, the analysis will focus on the comparison of the implemented prototype’s features with the ones presented in Related work, in order to see which ones were implemented and how the prototype’s features map on the array of desired ones.

Master thesis - Breiny's Architecture
The prototype implementation tries to follow as close as possible the recommended architectural patterns and guidelines. To support the argumentation, a class diagram will be presented to give a visual orientation through the prototype implementation presentation. The built prototype supporting Brainstorming Sessions on Microsoft Surface, further named Breiny, was developed as part of this thesis and uses all the above framework features.

Breiny - Second tap on the relation deletes it
This section will present the Breiny application’s user interface and the available interactions with it, features which will be evaluated by the users. Following the requirements for extensibility, modularity and flexibility, the subsequent visible objects were separated into several user controls.

BSCW architecture
Be careful when copying information from this article! The paper is already published and you will be charged with plagiarism! My thesis proposes several approaches as result of the research questions. Their validity of each approach should be verified by allowing users to interact with a prototype built to fulfill […]

Master thesis – Implementation of Repositories

Master thesis - Session Repository
is article presents the system architecture and the underlying decisions that were taken to achieve the above requirements. The system requires a repository for sessions, a repository for Brainstorming items and a native Windows application for achieving the baseline of desired features. Thus, a distributed client – server architecture is considered, exemplified here.

Master thesis – Architecture

In this section the application requirements will be presented. They are split into functional and non-functional ones. The first refers to all the features needed to be implemented, while the second category refers to performance, extensibility and scalability of the system.

Master thesis – Requirements elicitation

There are two sets of features that must or can be implemented: the first ones which regulate the brainstorming activity as a set of rules; the second ones add productivity to the process, enabling additional scenarios that improve the user experience.

Master thesis – Typical use case

My thesis claims as a basic concept that an ideal tabletop application supporting the brainstorming process must have an implemented answer to the issues raised above. Considering the first category of additional features which makes an application usable in the context of the brainstorming process, some properties were already mentioned and looked for in different applications: organization of ideas, relationships between ideas, sessions save and session restart for being continued.
