MT4j - A Cross-platform Multi-touch Development Framework
This article describes requirements and challenges of crossplatform
multi-touch software engineering, and presents the open source framework
Multi-Touch for Java (MT4j) as a solution. MT4j is designed for rapid
development of graphically rich applications on a variety of contemporary
hardware, from common PCs and notebooks to large-scale ambient displays, as
well as different operating systems. The framework has a special focus on
making multi-touch software development easier and more efficient. Architecture
and abstractions used by MT4j are described, and implementations of several
common use cases are presented.Comment: ACM EICS 2010, Workshop: Engineering patterns for multi-touch

Hacking with Multi-touch for Java (MT4j)
Developing applications for touch devices is hard. Developing touch based applications for multi-user input is harder. The Multi-Touch for Java (MT4j) toolkit supports developing touch based applications for multiple users. In this paper, we outline our experience using MT4j for developing a number of software applications to support developers working in co-located teams. Our experience using the toolkit will help developers to understand the nuances of the toolkit and design issues that can be applied to other toolkits for developing multi-user touch based applications
Making Gestural Interaction Accessible to Visually Impaired People
International audienceAs touch screens become widely spread, making them more accessible to visually impaired people is an important task. Touch displays possess a poor accessibility for visually impaired people. One possibility to make them more accessible without sight is through gestural interaction. Yet, there are still few studies on using gestural interaction for visually impaired people. In this paper we present a comprehensive summary of existing projects investigating accessible gestural interaction. We also highlight the limits of current approaches and propose future working directions. Then, we present the design of an interactive map prototype that includes both a raised-line map overlay and gestural interaction for accessing different types of information (e.g., opening hours, distances). Preliminary results of our project show that basic gestural interaction techniques can be successfully used in interactive maps for visually impaired people
A Multi-Touch Explorer Environment for Eclipse
The Multi-Touch Explorer Environment (MTEE) is a tool to aid developers during the production of multi-touch enabled applications. The MTEE tool integrates into the Eclipse IDE and can be used to record and playback user interactions with the program, compare sessions of recorded user interactions and investigate the evolution of the program behaviour. The tool presented in this thesis focuses on the Eclipse IDE and Multi-Touch for Java framework, as they are tools used by both Students and Professional developers. It is demonstrated that the Multi-Touch Explorer Environment can be integrated seamlessly into the Eclipse IDE. It is also demonstrated that the MTEE tool can be used to profile the user’s program with little impact on the performance of both the system or the program itself
Multi-Touch
The main contribution in this project is first, by optimize the multi-touch simulation to demonstrate the multi input abilities and proceed with hardware implementation which will be in the second stage of this project, Final Year Project (FYP) II
Brainstorming und Mind-Mapping im Multi-Device-Kontext. Konzeption und prototypische Implementierung fĂĽr Multi-Touch-Tabletop und Smartphone
Die vorliegende Arbeit beschreibt die Konzeption und prototypische ImplemenÂtierung einer Anwendung zur elektronischen UnterstĂĽtzung von Brainstorming- und Mind-Mapping-Sitzungen an einem multitouchfähigen Tabletop mit SmartÂphones. Während der Tabletop durch seine groĂźe, horizontal ausgerichtete Oberfläche die kollaborative Erstellung und Strukturierung von Ideen in Gruppen unterstĂĽtzt, werden Smartphones einen zusätzlichen Eingabekanal zur VerfĂĽgung stellen sowie Individualarbeit fördern. Somit wird zunächst einerseits die Motivation fĂĽr die Verwirklichung einer Anwendung zum Brainstorming und Mind- Mapping am Tabletop und andererseits das Potential einer Ergänzung eines solÂchen Systems durch zusätzliche private Geräte im Sinne der Multi-Device-InterÂaktion erläutert werden. Um eine geeignete theoretische Basis zu schaffen, wird darĂĽber hinaus ein detaillierter Ăśberblick ĂĽber die Entwicklung der TabletopÂtechnologie in den letzten Jahren und den dabei zentralen Forschungs- und ProÂblemfeldern im Kontext der Entwicklung von Benutzerschnittstellen fĂĽr Tabletopsysteme gegeben. Zudem werden schlieĂźlich auch im Rahmen der Arbeit relevante Aspekte der Multi-Device-Interaktion skizziert. Diesem theoretisch ausgerichteten Teil der Arbeit folgt schlieĂźlich eine Beschreibung der Entwicklung des Anwendungskonzepts und der dabei formulierten Anforderungen und Designzielen, welche in Form eines ersten, papierbasierten Prototypen visualisiert werden. Aufbauend auf diesen konzeptuellen Ăśberlegungen wird schlieĂźlich die konkrete technische Umsetzung der Anwendung Multi/Touch/Device Mind Mapper in Form eines High-Level-Prototypen auf Basis des MT4j-Frameworks (Tabletop) und des Android-Betriebssystems (Smartphone) beleuchtet. Eine DisÂkussion dieses finalen Prototypen und erster praktischer Erfahrungen sowie ein Ausblick auf Erweiterungsmöglichkeiten des Systems und ĂĽber den Rahmen der Arbeit hinaus gehende Fragestellungen schlieĂźen die Arbeit ab. Schlussendlich kann gezeigt werden, dass die im Rahmen des Anwendungskonzept definierten Anforderungen mit Hilfe der verwendeten Frameworks bis auf wenige Ausnahmen erfolgreich umgesetzt werden konnten. DarĂĽber hinaus kann der Anwendung durch die aus dem Testbetrieb gewonnenen Erkenntnisse eine grundsätzli che Praktikabilität attestiert, ebenso konnten einige Ansatzpunkte fĂĽr weitere Verbesserungen und Tests aufgedeckt werden
Interactive audio-tactile maps for visually impaired people
International audienceVisually impaired people face important challenges related to orientation and mobility. Indeed, 56% of visually impaired people in France declared having problems concerning autonomous mobility. These problems often mean that visually impaired people travel less, which influences their personal and professional life and can lead to exclusion from society. Therefore this issue presents a social challenge as well as an important research area. Accessible geographic maps are helpful for acquiring knowledge about a city's or neighborhood's configuration, as well as selecting a route to reach a destination. Traditionally, raised-line paper maps with braille text have been used. These maps have proved to be efficient for the acquisition of spatial knowledge by visually impaired people. Yet, these maps possess significant limitations. For instance, due to the specificities of the tactile sense only a limited amount of information can be displayed on a single map, which dramatically increases the number of maps that are needed. For the same reason, it is difficult to represent specific information such as distances. Finally, braille labels are used for textual descriptions but only a small percentage of the visually impaired population reads braille. In France 15% of blind people are braille readers and only 10% can read and write. In the United States, fewer than 10% of the legally blind people are braille readers and only 10% of blind children actually learn braille. Recent technological advances have enabled the design of interactive maps with the aim to overcome these limitations. Indeed, interactive maps have the potential to provide a broad spectrum of the population with spatial knowledge, irrespective of age, impairment, skill level, or other factors. To this regard, they might be an efficient means for providing visually impaired people with access to geospatial information. In this paper we give an overview of our research on making geographic maps accessible to visually impaired people
