Projektarbeit „Entwicklergruppenspezifische Codegenerierung bei 3D-bezogenen Anwendungen“

• Entwicklung von 3D-bezogenen Anwendungen ist interdisziplinär

• Unterschiedliche Entwicklergruppen arbeiten mit unterschiedlichen Werkzeugen, Formaten und Sprachen

• Integration der verschiedenen Entwicklungsergebnisse in ein Produkt aufwendig und fehleranfällig

à Es sind Codegenerierungswerkzeuge zu entwickeln, die aus einem Entwurfsmodell einer 3D-bezogenen Anwendung Code für verschiedene Entwicklergruppen generieren

Dist Scroll - A new User Interface(Programming, User study)

• The research group Embedded Interaction (www.hcilab.org) has developed a new interaction device that allows browsing of a hierarchical data structure (e.g. menus) by using distance as a input parameter.

• The goal of the project is to evaluate the usability and utility of this new interaction device by conducting a user study.

• To successfully evaluate this prototype and close open design issues, a little C programming is to be done to customize the program of the prototype as required in the user study.

• The user study is to be conducted with the envisioned user groups.

• No previous knowledge is required!

Displays Everywhere (Analysis, Programming, Implementation, Study)

• Push Services (e.g. SMS services for mobile phones) lack the ability to evaluate the user context before delivery. This results in a high annoyance factor with this services, e.g. when the user works highly concentrated and does not want to be disturbed.

• It is therefore reasonable to provide the desired information in the right context, e.g. weather forecasts when the user is deciding on whether or not to take his umbrella with him.

• The goal of this project is to build three information appliances using Smart-Its technology and deliver them into a real environment. The programming language is C under Windows using Microchips MPLAB IDE (integrated development environment).

• Bei einer Geschäftsidee ist es schwer, vorherzusagen, ob sie für die Kunden attraktiv ist

• Geschäftsidee: Handel mit Songs zwischen den Kunden in einer /(legalen) P2P-Tauschbörse

• Idee: Simuliere tausende Kunden mit jeweils eigenen Eigenschaften (“Alter”, “Bereitschaft zum Geldausgeben” , “hat zu 87% Spaß”)

• Kunden interagieren in der Simulation miteinander, Beobachtung der Gesamtkundenzahl/Zufriedenheit über bestimmten Zeitraum

• Aufgabe:

– Modellierung des Kundenverhaltens

– Implementierung der Simulation


Simulation einer Geschäftsidee


• Existierende “Validator”-Tools für Usability haben Problem: Oft nur dann Usability analysierbar, wenn zusätzliche Informationen vorhanden

• Beispiel: Information “Website für Kinder bestimmt” => Begrenzung des benutzten WortschatzesBeispiel: “Dieser Teil der Seite enthält Navigation” => Platzierung auf der Seite sollte einem der de-facto-Standards folgen

• Aufgabe: Programm z.B. in Java mit folgender Funktionalität

– Herunterladen und Layout-Analyse einer existierenden Seite

– Vom User auszufüllen: Fragebogen mit zusätzlichen Infos

– Durchführung einiger automatischer Usability-Tests


Tool zur semi-automatischen Usability-Analyse bestehender Webseiten


• Bei der Usability-Analyse von Websites sind “echte” User Tests aufwändig, direkte Beobachtung der User nötig

• Idee: Existierende Webseiten um JavaScript-Funktionalität erweitern, sodass sämtliche User-Aktionen (Klicks, Maus-Bewegungen, Scrollen auf der Seite) geloggt werden können

• Implementierung als HTTP-Proxy: Konvertierung erfolgt “on the fly” während Weiterleitung der Seiten

• Implementierung in Java oder C (evtl. Erweiterung bestehender Open-Source-Proxyimplementierung)


“Usability-Proxy” für Webseiten


Entwicklung von Multimedia-Anwendungen

• Multimedia-Entwicklung, z.B. Autorennspiel mit Flash (siehe MMP)• Wenig Unterstützung für Programmierung von Anwendungslogik• Stand der Technik bei „herkömmlicher“ Softwareentwicklung:

UML-Modelle + Codegenerierung=> Benötigt: Modellierung + Codegen. für Multimedia-Anwendungen

Aktueller Stand:• Einfach zu handhabende Modelle zur Übersicht über Fachklassen, Medien, User

Interface, Interaktion• Eclipse-basiertes Modellierungswerkzeug;

bisher: einfache Editoren, Codegenerierung für SVG

Offene Probleme:• Entwicklung grafischer Diagramm-Editoren• Konzepte für Integration in das Flash-Autorenwerkzeug

Webradio related research projects

Automatic detection and extraction of audio-streaming-URLs inwebradio websites

• Many websites that offer live audio-streams (webradio) only give access to their streams by the use of an "embedded player". These embedded players are often realized with javascript or some special software, eg. a plugin, a java application or a flash movie.... Hidden behind that there is often just a well known type of media stream like mp3, windows media or real media.

• The idea of this work is to develop a method to find and extract these stream urlsfrom such websites automatically, so that the stream can be accessed without using a webbrowser.

Design and evaluation of an user interface on a standalone box (settop box) for listening to webradio stations

• Imagine a standalone box like a regular hifi tuner with which one can access all available internet radiostations without using a pc or other additional equipment (like a tv). How can this huge amount of available stations be managed? How can a search be realized? How has the interfaces for controlling this box to look like? Is a remote control and a small display the right thing?

• These questions and a lot more have to be explored and new ideas have to be found and tested.

Webradio related research projects

Collaborative webradio listening toolbar for the webbrowser• Currently there are two types of directory services for webradio stations: human edited

and automatically build listings which get their information from the stream provider (upstream) by the use of specialized software (eg. NullSoft lists on shoutcast.com, live365.com only lists when using (and paying) their services, and this also applies to realmedia).

• The idea here is to integrate a webradio tuner toolbar into the browser where the user can browse entries of webradio stations that are already listed and where he can add new entries (like a bookmark) that are uploaded to the directory server and so shared with others. One of the major problems here is how to categorize the many links and how to get the required metadata from the user.

Other Webradio and Audio related projects also possible.
