Sebastian worked as a research assistant from May 2018 to April 2024. His research involved using the human himself as input, rather than the conventional mouse or touch interactions. These research projects converge in a PhD thesis on new implicit and explicit interaction methods for mobile devices that become possible through visual tracking of facial features.
He also developed multiple iOS and macOS software projects for industry clients and different research projects. While some of them are in Objective-C, most new projects are written in Swift. Speaking of Swift, he is also an Apple Certified Trainer for App Development with Swift. Therefore, he taught in multiple iterations of the iOS Application Development and Designing Interactive Systems 2 lectures.

Software Projects

Personal Orchestra

Real time conducting simulator

For this signature exhibit at House of Music in Vienna I defined the software architecture and coordinated media recording with development and deployment. For the exhibited I implemented—among others—a real-time AV manipulation pipeline and a driver for a proprietary USB device.

Centre Guide

Museum Guide Platform

The Aixplorer platform provides the foundation for our tourist guides. The Centre Charlemagne app uses this platform to provide guides for different exhibitions with multimedia content. I coordinated the integration of different exhibitions into the app, implemented, and maintained the iOS codebase.

Kieke App

Museum Guide and CMS

This app for iOS and Android guides visitors through Freilichtmuseum am Kiekeberg. AR features bring history to life and allow unique memories. I led this project, mediated between different stakeholders to shape a product with great cost–benefit for our customer.

Terra Mosana

Novel MR Interactions for the Aachen Cathedral

Visit the 3D scan of the Aachen cathedral through a magic lens on your iPhone. I have implemented the iOS app and used it as testbed to answer multiple research questions.

Inventory

Digitalization of asset management

This software allows the lab to keep track of its inventory. The inventory system helps to find items, print rental forms, and assists the reinventorization process. I created the iOS and macOS client apps.

FLApp

The Future Lab Aachen App

This mobile tourist guide showcases scientific activities in the city center with multimedia and AR content. During my time as student assistant my I was the lead software architect for the iOS app.

iEat

Mensa menu for iOS and watchOS

I created this app completely altruistically and not just because I wanted to see the mensa menu on my watchface... /s

Touch Up

Touchscreen Driver for macOS

This user-space driver can inject common mouse events and pinch-to-zoom gestures with any USB HID-compliant touchscreen. I open-sourced the code on my GitHub.
