Opera.Guru is an application suite to provide subtitles for live opera performances. (see www.opera.guru for details) The existing application contains a web-based frontend and smartphone app (Android/iOS) and a web-based CMS. The task of this thesis is to add new funcionality and improve existing ones. The goal of this extension is to use the Opera.Guru application suite for events other than opera and to access new user groups as well as new application scenarios. Basic programming skills and knowledge with mobile, web and server applications are recommended. The work for this thesis will include a user study to evaluate the web app.

See the project's website for further information and finished theses about opera.guru.

Die Elektrifizierung der Gitarre und der Synthesizer haben vor hundert bzw. fünfzig Jahren die Musik drastisch verändert. Heute sind es digitale und mobile Technologien aller Art von Smartphones, über Mikrocomputer bis hin zur Sensortechnik und künstlicher Intelligenz, die Musik, das Musikmachen und den Musikkonsum verändern. Dazu gehören neue digitale Musikinstrumente und Klangwelten genauso wie neue Interaktionsformen in der Live-Musik, die das Publikum mit den Musikern "vernetzen". Aufbauend auf unsere Forschungsprojekte Breaking The Wall (https://www.piglab.org/breakingthewall) und Sparkling Instruments (http://www.piglab.org/sparkling-instruments) sowie Music Participation (http://www.musicparticipation.com/) bieten sich viele Möglichkeiten für Bachelor- und Masterarbeiten sowie Praktika (P1 und P2) für alle Musik- und Computer-Interessierten.

Design or method cards are an approach to find inspiration and promote innovation, to think about user needs, behaviour and interaction, to seek for sustainability and to enable gamification and playfulness. The Design Cards To Go Web App (https://designcards.cosy.univie.ac.at/) is a web-based application to provide card sets online. Currently, the app implements the TMAP Design Cards for the design of technology-mediated audience participation in live music. This topic can be done as Bachelor thesis or Praktika (P1, P2).

Die Wiener Ballsaison ist nicht nur einzigartig und ein besonderes Erlebnis für alle Besucher, sondern auch ein wichtiger Faktor für den Tourismus, die Wirtschaft und das Image der Stadt Wien. Egal ob auf großen oder kleinen Bällen, im Vordergrund stehen Musik, Tanz und Unterhaltung in eleganter Atmosphäre. Doch auch in den Ballsaal hat auch nach über hundert Jahren die digitale Technik Einzug gehalten. Seien es die Smartphones der Besucher, große Bildschirme auf den Gängen, komplexe Lichtshows oder Barcode-Scanner am Eingang statt der herkömmlichen Eintrittskarte. Die Ballbesucher tanzen und unterhalten sich nicht mehr ausschließlich, sondern posten die schönsten Eindrücke online in diversen sozialen Medien. Am Charakter eines Balles selbst hat sich nun nicht viel geändert. Aber die Möglichkeiten zur Kommunikation, Interaktion und letztendlich Unterhaltung in diesem Rahmen sind mehr geworden. Das wirft unmittelbar Fragen auf: Wie können digitale Systeme im Rahmen eines Balles genutzt oder weiterentwickelt werden und welchen Bedarf gibt es? Die konkreten Fragestellungen für eine Abschlussarbeit in diesem Themenkomplex sind vielseitig und können sowohl technischer als auch gestalterischer Natur sein.

The Mastodon network - currently 4.4 million active accounts on +4000 servers - is regarded as the most successful alternative online social network yet:

https://joinmastodon.org

Unlike Twitter, Facebook, Instagram, TikTok - this service is NOT based on manipulative strategies like targeted advertising and algorithmic outrage maximisation - which are posing imminent threats to democracies worldwide - and for this reason, the network keeps evolving rapidly.

→ However, its decentralized nature creates exciting challenges for monitoring "network health".

Your task is to:

1. Conduct research on the current state-of-the-art in monitoring of federated network statistics (e.g. nr. of posts per instance over time, blocking events, outages...)
2. Apply your insights and ingenuity to help improving the situation, e.g.
   
   1. Aggregation of publicly available statistical data (via mastodon server APIs)
   2. Setup a public monitoring service directory - similar to https://git.feneas.org/feneas/fediverse/-/wikis/instance-monitoring-sites
   3. Propose new ideas on "how to measure network health" of a federated online social network

If you are interested in the future of online social networking systems (democratically legitimised moderation and algorithms + resistance against spam, censorship, denial-of-service...) then this topic may be something for you

The ESP8266 offers an interesting WiFi-enabled small-scale embedded platform. Your task is to extend the MicroPython firmware available for it to enable its wireless interface's promiscuous mode. This lets an ESP8266 act as a passive WiFi sensing and measurement device. Based on your implementation, you design a distributed experiment with multiple devices that makes use of your new feature, e.g. track WiFi beacons from smartphones across geographical areas in a privacy-preserving manner.

The Optimized Link State Routing protocol version 2 (OLSR2 on GitHub, RFC 7188) is a routing protocol for wireless mesh networks. Your task is to automate tests against OLSR2 that try its functionality and check its correct functioning for a variety of valid and invalid inputs, both from the network and from local configuration. Vectors include the syntax and semantics of OLSR2's RFC 5444-encoded messages, but also any config files that the deamon uses, or the operating system's routing tables (see e.g. Routing Tables of Death). Since OLSR2 aims to run on low-power embedded hardware platforms such as WiFi routers, DoS scenarios (memory / CPU / storage exhaustion) are in scope as well. Additionally, glitches should be analysed for their effect on a practical mesh network of ~10 devices. Since OLSR2 is Free, Libre Open Source Software (FLOSS), you should also disclose responsibly and fix any bugs you may find!

Academic work includes presenting one's research results to the community at conferences and in printed publications. Unfortunately, the dissemination of conference dates, times, places etc. through calls-for-papers happens in an ad-hoc manner, e.g. by e-mail or on websites.

Your task is to design a metadata system for conference organizers that encodes deadlines, keywords, tracks, formats, roles and so on in a structured, machine- and human-readable form and includes interfaces for both professional conference management systems and end-user calendar software. You design both the format for data exchange, and the distributed, federated system architecture that provides a simple implementation path for interested parties (servers and clients).

The Smart Home communication protocol environment is heavily fragmented and many standards compete for integration. Thus, interoperability and unified control are not possible in most cases.  

Your task is to:

1. Research the most widely used Smart Home communication standards and the corresponding APIs
2. Design and Develop an API to cover all identified use cases/API calls from all of the aforementioned standard

Your Project should be implemented in a lightweight language such as MicroPython. Experience programming for microcontrollers (Arduino, ESP, NodeMCU) would be a plus.

Die am MIT betriebene "Moral Machine" (http://moralmachine.mit.edu/) ist eine Plattform zur publikumswirksamen Diskussion ethischer Dilemmata in der IKT, z.B. im Kontext von autonomen Fahrzeugen. Im Rahmen des Projekts PANDORA (https://cosy.cs.univie.ac.at/research/projects/project/271/) werden verwandte Fragestellungen vor dem erweiterten Horizont der langfristigen gesellschaftlichen Entwicklung und im Hinblick auf das zugrundeliegende Menschenbild erforscht, um so aus der Disziplin der Informatik heraus den Diskurs über eine nachhaltige IKT aktiv zu gestalten. In dieser Arbeit soll, basierend auf einer detaillierten Analyse der Moral Machine, hierzu eine web-basierte Plattform entstehen, die deren Konzept im Hinblick auf Fragestellungen aus der philosophischen Anthropologie erweitert.
