There is a great variety of applications targeting the creation of music on mobile computing platforms. These applications range from emulated instruments to complex multi-track recording and editing systems. However, the interaction is usually restricted to simple touch input. The lack of haptic feedback and the absence of pressure sensing create an “input bottleneck”, an unbalance between powerful sound processing and poor handling. While there have been various approaches to extend the input capabilities by exploiting the sensors embedded in modern mobile devices, little work has been done to investigate the use of tangibles in combination with mobile devices in order to create new possibilities for expressive interaction within music creation contexts.

The goal of this thesis is to prototype a tangible object which allows for expressive musical interaction by implementing a pressure sensing mechanism.

Research Questions

• How can low-fidelity pressure sensing for musical tangibles on tablet devices be accomplished?
• What musical tasks can be executed using pressure-sensitive tangibles on capacitive touchscreens?
• Do pressure-sensitive tangibles allow for a precise and reliable control of musical parameters?

Tasks

• Build a tangible prototype using sensors and electronics prototyping platforms (e.g. Arduino)
• Create a software interface (iOS/Android) that communicates with the tangibles and produces musical control data (e.g. MIDI-Messages)
• Think about application scenarios
• Conduct a user study to evaluate the implemented prototype

Requirements

• Student in Media Informatics, Computer Science or related field
• Solid programming skills in an object-oriented programming language (i.e. Java, C#, C++, Python)
• Musical background (e.g. instrumentalist, producer, composer, etc.)
• Preferably: First experiences with mobile computing and/or electronics prototyping
• Interest in creating new musical interfaces

Usually, the interaction in musical tabletops is limited to rotating and moving objects on a two-dimensional surface. The goal of this thesis is to prototype a tangible object which augments the simple rotation of tangible objects by designing objects with touch-sensitive surfaces. Rotating these objects should affect different musical parameters depending on where users grab them.

Research Questions

• Which object shapes are suited for controlling multiple musical parameters with one tangible?
• Do such tangibles allow for new forms of expressive tangible musical interaction?

Tasks

• Design and build tangible controller objects
• Create a software interface (iOS/Android) that communicates with the tangibles and produces musical control data (e.g. MIDI-Messages)
• Think about application scenarios
• Build and evaluate a prototype application

This project involves the re-design of the eLabBench for Microsoft Surface 2 tabletops. It is a collaboration with students and researchers from the IT University of Copenhagen.

The eLabBench is a tabletop application for biologists (video in danish). It augments laboratory benches digital capabilities and links data from desktops computers to tabletops or other devices. The goals of the eLabBench re-design are 3 fold:

• Port the application from Flex to .Net and leverage the Microsoft Surface specific apis to provide a better experience.
• Connect to new cloud services developed at the IT University of Copenhagen for handling the data. These services rely on Activity Based Computing (ABC) principles where users' data is organized around activities rather than hierarchical files and folders. The current services are built on top of AppHarbor.- This part may be handled by students from the IT University of Copenhagen.
• Explore how the MS Surface hardware could handle the constraints of laboratory work. Example questions to answer: Should a new glass plate be added on top of the Surface to protect from liquid spills, can the existing surface be cleaned with alcohol...

This project(s) is the follow up to the NoxDroid.org project (paper, poster).

It involves building mobile sensors plugged to Android phones that can report information about the environment (air quality, radio-activity, noise, etc.).The idea behind the project is of using low-cost and easy to build sensors which lets citizens gather information about their environment, rather than relying on expensive and precise sensors managed by public or private laboratories. In the long run, the hope is that the quantity of data collected will balanced the lack of precision.

This project is big and can be divided into 3 sub-projects (carried by different students):

• A plug and play sensor platform based on the IOIO board (Arduino for Android).
• A mobile (Android) app, gathering, caching and uploading the sensor data. Providing live feedback on the sensor data.
• A web platform (based on the Google App Engine or equivalent), gathering data from the mobile app (you should develop a REST API), providing visualization both of the personal data of a user and anonymized/aggregated data.
• Alternatively a sub-project could be to develop the sensor platform and mobile application for iOS devices

Most tabletop applications assume that the whole tabletop will be free of objects and the whole screen real estate available for display. Yet with their horizontal surfaces, tabletops afford objects laying on them as we could notice in the eLabBench project.

This projects aims at studying how people are currently using tables or desks, and analyzing data from existing tabletop applications (mainly from the eLabBench) to better understand the types of objects laying on them.

There are plenty of projects augmenting or integrating physical objects on tabletops. The idea here is rather to define the types and properties of objects that shouldn't be augmented (e.g. a sandwich on a meeting table).This qualitative and quantitative information would be useful for the next step: designing mechanisms to handle occlusion such as this project from Purdue Univ.

Many "smart" or programmable watches are currently reaching the market, but they are often cumbersome to program and require extensive JAVA or C knowledge.

The goal of this project is to build an toolkit that designers could use to develop applications for watches. The toolkit should provide access to the watch functionalities (sensor data, display) in a designer friendly environment (Flash, Processing, Max/MSP or others).

For reference:

List of watch candidates: inpulse, Texas Instruments EZ430 Chronos (get) metawatch, LiveView, dynawatch.

An extra set of things would be to provide easy to use machine learning or gesture recognition mechanisms.

The aim of this project is to explore the design of wireless devices that do not rely on embedded batteries to operate. Instead these devices gather energy from an electro-magnetic field present in the environment (using the same principle as RFIDs but with interactive capabilities). This principle could be used to create wireless and battery-less remote controls.

Some information on the first practical steps are available here to give you an idea of the ease (or difficulty).

Tasks:

• Build a first prototype capable of reading a defined ID stored on the micro-controller
• Build a second prototype capable on transmitting input information
• Build a third prototype capable of displaying feedback (turning LEDs on/off)
• Evaluation/Benchmarking of the technical limits of the prototype (number of input per seconds, ability to handle many inputs at the same time)
• Brainstorming and concept development of applications
• Build device a series of small prototypes (remote-control, presence sensor, etc.)
• Written thesis and presentation of your work

Ein Smartphone ohne Touchscreen? Das ist heute kaum mehr vorstellbar. Doch Touchscreens haben nicht nur Vorteile:
Ein Problem ist ihre Schmutzanfälligkeit. Hierdurch werden sogenannte „smudge attacks“ möglich, bei welchen ein Angreifer das Passwort anhand von Flecken auf dem Bildschirm ableitet. Dies kann zu schwerwiegenden Sicherheitslücken führen. Vorallem musterbasierte Passwörter, wie sie von Andriod Geräten bekannt sind, neigen dazu, Spuren auf dem Display zu hinterlassen.
Das Ziel dieser Arbeit ist es, eine Konzept zu finden, welches smudge attacks bei musterbasierten Passwörtern entgegen wirkt. Die Eingabe soll dabei ähnlich intuitiv und einfach von statten gehen, wie es bei der Originalimplementierung von Android der Fall ist.

Folgende Teilaufgaben sind zu erfüllen:

• Recherche verwandter Arbeiten
• Planung und Implementierung des Prototypen
• Evaluation des Prototypen
• Ausarbeitung und Präsentation der Ergebnisse
